Description

【0001】
【発明の属する技術分野】
本発明は、クローラ式荷役車両に関する。
【0002】
【従来の技術】
この種、クローラ式荷役車両としては、クローラクレーン(例えば、実開平3ー66988号参照)やクレーン付きクローラダンプ(例えば、特開平6ー127441号、実開平4ー75783号、実開平4ー34184号参照)が有る。
【0003】
クローラクレーンはクローラ式の下部走行体上に上部旋回体を有し、上部旋回体上にクレーン、運転席及び駆動源を有する。この車両では例えば、クレーンで機材を吊り、別の場所で待機中の運搬車両まで移動し、旋回し、積載する。
【0004】
一方、クレーン付きクローラダンプはクローラ式の下部走行体上に上部機体を固設され、上部機体上に旋回自在なクレーン、ダンプ式の四角形の荷台、運転席及び駆動源を有する。この車両では例えば、クレーンで機材を吊りつつ、旋回し、荷台に積載し、自走し、ダンプする。
【0005】
【発明が解決しようとする課題】
ところで近時、偏狭かつ狭隘な傾斜地や木々が密生する山林でも、電柱や丸太等の長尺機材を機動性よく、素早く積載し、運搬できる荷役車両の提供が要請されている。ところが上記従来のクローラ式荷役車両では、次に示すように、上記要請に対応できない問題がある。
【0006】
(1)上記クローラ式荷役車両は下部走行体がクローラ式であるため、偏狭かつ狭隘な傾斜地や木々が密生する山林でも難なく走破できる。ところがクローラクレーンでは荷台が無いため、運搬車両もクローラ式としなければならず、不経済である。一方、クレーン付きクローラダンプは運転席が旋回しないため、偏狭かつ狭隘な傾斜地や木々が密生する山林等で頻発する後進走行時、オペレータに疲労を与えることになる。
【0007】
(2)上記クローラ式荷役車両はクレーンを搭載している。ここでクローラクレーンではクレーンを搭載する上部旋回体が旋回する。一方、クレーン付きクローラダンプではクレーン自体が旋回する。このため車両が停車状態でも、クレーンのリーチ範囲内で吊荷作業を行える。ところが偏狭かつ狭隘な傾斜地や木々が密生する山林では、仮に丸太等の長尺機材を吊り上げても、その長尺機材が密生する木立や傾斜地等で遮られて長尺機材の移動可能空間が狭いときが多々ある。このようなとき、狭い空間に長尺機材をすり抜けさせるため、長尺機材を押し引きする手作業が必要となる。即ち少なくとも2人作業となり、作業効率が悪い。
【0008】
(3)上記クレーン付きクローラダンプは荷台を有するために積載物を集荷して運搬できる。ところが荷台が単なる四角形であるため、長尺機材の長さを予め揃えておかないと、運搬不能、積み残し、重複往復等の問題が生ずる。仮に荷台からはみ出して長尺機材を積載したり、荷台の前縁や側縁上に長尺機材の一端部を乗せると、傾斜地や不整地では長尺機材の積載が不安定となり、高速走行が困難となる。
【0009】
本発明は、上記要請及びこの要請に対する従来技術の問題点に鑑み、たとえ偏狭かつ狭隘な傾斜地や木々が密生する山林でも、電柱や丸太等の長尺機材を機動性よく、素早く積込んで運搬できるクローラ式荷役車両を提供することを目的とする。
【0010】
【課題を解決するための手段および作用・効果】
上記目的を達成するため、本発明に係わるクローラ式荷役車両の第1に、クローラ式の下部走行体と、下部走行体上に設けた上部旋回体と、上部旋回体上に設けた運転席、駆動源、旋回基台及び荷台と、旋回基台に基端をピン連結された関節アームと、関節アームの先端に設けた把持手段とを有することを特徴とするクローラ式荷役車両において、 (1) 運転席を上部旋回体上の前部に配置し、 (2) 駆動源と旋回基台とをこの順で運転席の左右いずれか一方に前部から後方に向けて配置し、 (3) 前縁が運転席の後面と、旋回基台の運転席側面と、旋回基台の後面とに沿って延設された荷台を上部旋回体上の後部に配置したことを特徴としている。
【0011】
上記第1構成によれば、クローラを自走させ、停止させ、上部旋回体や旋回基台を旋回させ、停止させ、関節アームを起伏させ、停止させ、また把持手段を作動させることにより、偏狭かつ狭隘な傾斜地や木々が密生する山林でも、関節アームのリーチ範囲内に存在する電柱や丸太等の長尺機材を機動性よく、素早く荷台に積載し、運搬できる。具体的にはクローラ式であるため、偏狭かつ狭隘な傾斜地や木々が密生する山林でも難なく走破できる。しかも運転席が上部旋回体上に搭載されているため、後進時でも上部旋回体を旋回させて運転席を後進方向に向けることができ、この結果、前記後進方向を前進方向にすることができる。従ってオペレータの疲労を軽減できる。また把持手段を有しているため、空間において長尺機材を固定的に把持でき、従って狭い空間での手作業によるすり抜け移動を機械的に行うことができる。
そして、長さが多少異なる長尺機材でも他の長尺機材と共に荷台に一括して積載できる。このため積み残しや重複往復が無く、一度に運搬できる。
【0014】
第2に、上記第1構成において、(1)運転席と旋回基台とをこの順で上部旋回体上の前部から後方に向けて配置し、(2)駆動源を運転席と旋回基台との左右いずれか一方に配置し、(3)荷台の前部の駆動源側が駆動源の上方を経て前方へ延設されると共に、この前方へ延設された荷台の前部の運転席と旋回基台との側の縁が旋回基台の後面を経て後方へと延設された荷台を上部旋回体上の後部に配置したことを特徴としている。
【0015】
上記第2構成によれば、長さが全く異なる超長尺機材でも他の長尺機材と共にに荷台に一括して積載できる。このため積み残しや重複往復が無く、一度に運搬できる。
【0016】
第3に、上記第1又は第2構成において、荷台の底面の左右端部の夫々に前後方向に長い凹部を有したことを特徴としている。
【0017】
上記第3構成によれば、荷台に転がり易い丸太等の長尺機材を積載しても、最初に積載される丸太が先ず荷台の底面の左右端部のいずれかの凹部に転がり落ち、停止してそれ以上転がることがなくなる。次の丸太が前に積載した丸太と荷台との間にできた空隙に転がり落ち、停止してそれ以上転がることがなくなる。以降順次積載される丸太がこれを要領で停止してそれ以上転がることがなくなる。従って傾斜地での走行時でも丸太等が荷台上で転がることがなく、作業性が向上する。
【0018】
【発明の実施の形態及び実施例】
以下、第1実施例なる例機を図1〜図4を参照し説明する。図1〜図3に示すように、例機はクローラ式の下部走行体10上に旋回軸J1回りに旋回自在とされた上部旋回体20を有する。そして上部旋回体20上に運転席30と、駆動源40と、旋回軸J2回りに旋回自在とされた旋回基台50と、荷台60とを有す。そして旋回基台50上に関節アーム70を有し、関節アーム70の先端に把持式手首80(いわゆる、クランプ80)を有す。尚、以下に記載の「左、右、前、後」の方向用語は運転席30を基準としている。
【0019】
荷台60は、図4にも示すように、四角形であり、次の通りダンプ可能とされている。即ち荷台60の底の後部裏面と、上部旋回体20の後部とが第1ピン61でピン連結される。また荷台60は底に前後方向に長い凸部62を有する。そして凸部62の裏側上面に、かつ第1ピン61の位置よりも前方位置に、油圧シリンダ63のロッド先端が第2ピン64でピン連結される。そして油圧シリンダ63のボトム側端は第3ピン65で上部旋回体20の後部にピン連結される。また荷台60の左右側面にはサイドバー66を出入れ自在に立設してある。
【0020】
関節アーム70は、図2に示すように、旋回基台50に基端をピン連結され、第1油圧シリンダ71によって起伏自在とされた第1アーム72と、第1アーム72の先端にピン連結され、第2油圧シリンダ73によって起伏自在とされた第2アーム74と、第2アーム74の先端にピン連結され、同じく第2油圧シリンダ73によって起伏自在とされた第3アーム75とを有する。そして第3アーム75の先端にクランプ80が設けられ、油圧シリンダ(図示せず)によって開閉自在とされている。
【0021】
尚、図1〜図3に示すように、上部旋回体20上の運転席30の右側位置、旋回基台50の前方位置、かつ駆動源40の上方位置には旋回基台50、関節アーム70及び駆動源40等を操作するための各種レバーや計器等を配置した操作盤90と、これら各種レバーを操作するためのオペレータ用の座席100が設けてある。
【0022】
上記構成によれば、クローラを自走させ、停止させ、上部旋回体20や旋回基台50を旋回させ、停止させ、第1、第2油圧シリンダ71、73によって第1〜第3アーム71、72、75を起伏させ、停止させ、またクランプ80を開閉させることにより、偏狭かつ狭隘な傾斜地や木々が密生する山林でも、関節アーム70のリーチ範囲内に存在する電柱や丸太等の長尺機材を機動性よく、素早く荷台60に積載し、運搬できる。
【0023】
尚、例えば短い長尺機材や土砂等を積載するときは、予め、前後サイドバー66、66間に仕切り板を設け、ことにより荷台60を油圧シリンダによってダンプさせることによりこれらを積み下ろしできる。勿論、ダンピング作業が主体となるときは、上記図1〜図4に示したサイドバー66式の荷台60ではなく、図5に示すような左右囲い式の荷台60Aの方が望ましい。
【0024】
上記第1実施例の作用効果をより具体的に項目列記する。
(1)例機はクローラ式である。このため偏狭かつ狭隘な傾斜地や木々が密生する山林でも難なく走破できる。
【0025】
(2)しかも例機は運転席30が上部旋回体20上に搭載されている。このため後進時でも、上部旋回体20を旋回させて運転席30を後進方向に向けることができ、この結果、前記後進方向を前進方向とすることができる。従ってオペレータの疲労を軽減できる。
【0026】
(3)また例機は従来技術のようなクレーンでなく、クランプ80を搭載している。このため空間において、長尺機材を固定的に把持できる。従って従来の狭い空間での手作業によるすり抜け移動を無くすことができる。
【0027】
(4)また例機は荷台60の底に前後方向に長い凸部62を有する。即ち荷台60の左右端に前後方向に長い凹部を有する。このため転がり易い丸太を荷台60に積載しても、最初の丸太が先ず凹部62内に落ち込んでその転がりが阻止される。そしてその後、次々と積載される丸太も互いの隙間に落ち込んで互いの転がりが阻止される。即ち、例機が傾斜地を走行しても丸太が転がることがなく、作業性が向上する。
【0028】
(5)また例機は凸部62の裏側上面に油圧シリンダ63のロッド先端を第2ピン64でピン連結している。このため荷台60の伏せ状態での油圧シリンダ63の傾倒角を大きくすることができる。従って油圧シリンダ63を小形化、また油圧を低くできる。この理由は次の通り。
【0029】
例機は上部旋回式のクローラ式荷役車両である。従って第3ピン65を、上部旋回体20が旋回した時でも、第3ピン65の部位が下部走行体10やクローラ上の土砂に衝突しないように、下部走行体10の上面以上(即ち上部旋回体20の下面以上の高さ)の位置に設ける必要がある。一方、第2ピン64は、例機全体の重心位置を低める観点から、より低いことが望ましい。このため、荷台60の伏せ状態での油圧シリンダ63の傾倒角が小さくなるという背反事象が生ずる。背反事象である理由は、このように荷台60の伏せ状態での油圧シリンダ63の傾倒角が小さいと、荷台60を起立へ移行させるとき、油圧シリンダ63では極めて大きな起立力を発生させなければならないからである。
【0030】
他の実施例を項目列記する。
【0031】
上記例機の荷台60、60Aは、図1〜図5に示したように、四角形であり、上部旋回体20上で運転席30と旋回基台50との後面から後方に配置されている。このような荷台60、60Aに対し、次のような荷台60B、60Cとすると、作業効率の向上を機体できる。尚、以下において、上記図1〜図5と同一要素には同一符号を付して重複説明を省略する。
【0032】
(1)図6に示すように、運転席30を上部旋回体20上の前部に配置し、駆動源40と旋回基台50とをこの順で運転席30の右側(又は左側)に前部から後方に向けて配置した例機において、図7に示す荷台60Bを上部旋回体20上の後部に配置したものである。即ち荷台60Bは、図7に示すように、その前縁が運転席30の後面F1と、旋回基台50の運転席30側面F2と、旋回基台50の後面F3とに沿って延設されて構成される。このような荷台60Bによれば、長さが多少異なる長尺機材でも、積み残しや重複往復することなく、他の長尺機材と共に一度に積載し運搬できる。
【0033】
(2)図8に示すように、運転席30と旋回基台50とをこの順で上部旋回体20上の前部から後方に向けて配置し、駆動源40を運転席30と旋回基台50との左右いずれか一方に配置した例機において、図9に示す荷台60Cを上部旋回体20上の後部に配置したものである。即ち荷台60Cは、図9に示すように、その前部の駆動源40側が駆動源40の上方を経て前方へ延設されると共に、この前方へ延設された荷台60C 前部の運転席30と旋回基台50との側の縁S1が旋回基台50の後面S2を経て後方S3へと延設されて構成される。尚、旋回基台50は車体中央部寄りに設ける方が、車体の左右外側位置での関節アーム70のリーチ範囲が均等化するという利点がある。そこで本例では、前記運転席30と旋回基台50とを車体中央部に設け、左側に所定角θだけ回転自在とされた座席台110を設け、この座席台110上に操作盤90と座席100とを設けた。このような荷台60Cによれば、長さが全く異なる長尺機材でも、積み残しや重複往復することなく、他の長尺機材と共に一度に積載し運搬できる。

BACKGROUND OF THE INVENTION
The present invention relates to a crawler type cargo handling vehicle.
[0002]
[Prior art]
As this type of crawler type cargo handling vehicle, a crawler crane (see, for example, Japanese Utility Model Laid-Open No. 3-66988) or a crawler dumper with a crane (for example, Japanese Patent Laid-Open No. 6-127441, Japanese Utility Model Laid-Open No. 4-75783, Japanese Utility Model Laid-Open No. 4-34184). Issue).
[0003]
The crawler crane has an upper swing body on a crawler type lower traveling body, and has a crane, a driver's seat, and a drive source on the upper swing body. In this vehicle, for example, the equipment is suspended by a crane, moved to a transport vehicle waiting in another place, turned, and loaded.
[0004]
On the other hand, a crawler dumper with a crane has an upper body fixed on a crawler type lower traveling body, and has a crane, a dump-type square loading platform, a driver's seat, and a drive source that can turn freely on the upper body. In this vehicle, for example, the crane turns while hanging the equipment with a crane, loads it on the loading platform, self-propels, and dumps.
[0005]
[Problems to be solved by the invention]
By the way, recently, even in narrow and narrow slopes and forests with dense trees, it is required to provide a cargo handling vehicle that can load and transport long equipment such as utility poles and logs quickly with high mobility. However, the conventional crawler type cargo handling vehicle has a problem that it cannot respond to the request as described below.
[0006]
(1) Since the above-mentioned crawler type cargo handling vehicle has a crawler type lower traveling body, the crawler type cargo handling vehicle can run without difficulty even in a narrow and narrow sloped land or a mountainous forest. However, since a crawler crane does not have a loading platform, the transport vehicle must also be a crawler type, which is uneconomical. On the other hand, the crawler dumper with a crane does not turn the driver's seat, so that it causes fatigue to the operator during reverse travel frequently occurring in a narrow and narrow slope or a forest with dense trees.
[0007]
(2) The crawler type cargo handling vehicle is equipped with a crane. Here, in the crawler crane, the upper turning body on which the crane is mounted turns. On the other hand, in a crawler dumper with a crane, the crane itself turns. For this reason, even when the vehicle is stopped, the lifting work can be performed within the reach range of the crane. However, in narrow and narrow slopes and forests where trees are densely populated, even if long equipment such as logs is lifted, the long equipment can be blocked by dense trees and slopes, and the space for moving long equipment is narrow. There are many times. In such a case, it is necessary to push and pull the long equipment in order to pass the long equipment through the narrow space. That is, at least two people work and work efficiency is bad.
[0008]
(3) Since the crawler dumper with a crane has a loading platform, it can collect and transport a load. However, since the loading platform is a simple quadrilateral, problems such as inability to transport, unloading, and overlapping reciprocation occur unless the length of the long equipment is aligned in advance. If you load a long piece of equipment out of the loading platform or place one end of the long piece of equipment on the front edge or side edge of the loading platform, the loading of the long piece of equipment becomes unstable on sloping or uneven terrain, and high-speed running It becomes difficult.
[0009]
In view of the above-mentioned demand and the problems of the prior art for this demand, the present invention quickly loads and transports long equipment such as utility poles and logs with good mobility even in narrow and narrow slopes and forests with dense trees. An object of the present invention is to provide a crawler type cargo handling vehicle.
[0010]
[Means for solving the problems and actions / effects]
In order to achieve the above object, first of the crawler type cargo handling vehicle according to the present invention, a crawler type lower traveling body, an upper swing body provided on the lower travel body, a driver seat provided on the upper swing body, driving source, a swivel base and loading platform, and joint arm is pin-connected to the base end to the swivel base, the crawler type handling vehicle, characterized in that it comprises a gripping means provided at the distal end of the articulated arm, (1 ) The driver's seat is arranged at the front of the upper revolving structure, (2) The drive source and the swivel base are arranged in this order on either the left or right side of the driver's seat from the front to the rear, (3) The front edge is characterized in that a cargo bed extending along the rear surface of the driver's seat, the side surface of the driver's seat of the turning base, and the rear surface of the turning base is arranged at the rear portion of the upper turning body.
[0011]
According to the above first configuration, the crawler is self-propelled, stopped, the upper swing body and the swing base are swung, stopped, the joint arm is raised and stopped, and the gripping means is operated. Even in narrow, sloping terrain and forests with dense trees, long equipment such as utility poles and logs existing within the reach range of the joint arm can be quickly loaded and transported on the platform. Specifically, because it is a crawler type, it can run without difficulty even in narrow and narrow slopes and forests with dense trees. Moreover, since the driver's seat is mounted on the upper revolving structure, the upper revolving structure can be turned to turn the driver's seat in the reverse direction even when moving backward, and as a result, the reverse direction can be set to the forward direction. . Therefore, operator fatigue can be reduced. In addition, since the gripping means is provided, it is possible to grip a long piece of equipment in a fixed space, and thus mechanically move through by hand in a narrow space.
Even long equipment with slightly different lengths can be loaded together with other long equipment on the carrier. For this reason, there are no leftovers or overlapping round trips, and it can be transported at once.
[0014]
Second, in the first configuration, (1) the driver's seat and the turning base are arranged in this order from the front to the rear on the upper turning body, and (2) the drive source is placed on the driver's seat and the turning base. (3) The driving source side of the front part of the loading platform is extended forward through the driving source, and the front driver's seat of the loading platform extended forward And a pedestal of which the edge on the side of the slewing base extends rearward through the rear surface of the slewing base, and is arranged at the rear part on the upper slewing body.
[0015]
According to the second configuration, even ultra-long equipment having completely different lengths can be loaded on the carrier together with other long equipment. For this reason, there are no leftovers or overlapping round trips, and it can be transported at once.
[0016]
Thirdly, in the first or second configuration , each of the left and right end portions of the bottom surface of the loading platform has a concave portion that is long in the front-rear direction.
[0017]
According to the third configuration, even when a long piece of equipment such as a log that is easy to roll is loaded on the loading platform, the first loaded log first rolls down into one of the left and right recesses on the bottom of the loading platform and stops. No more rolling. The next log rolls down into the gap created between the previously loaded log and the loading platform, stops and stops rolling any further. Logs that are sequentially loaded thereafter stop this and stop rolling any more. Therefore, even when traveling on an inclined land, logs and the like do not roll on the loading platform, and workability is improved.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
An example machine according to the first embodiment will be described below with reference to FIGS. As shown in FIGS. 1 to 3, the example machine has an upper revolving unit 20 that can be swung around a revolving axis J <b> 1 on a crawler-type lower traveling unit 10. A driver seat 30, a driving source 40, a turning base 50 that can be turned around the turning axis J <b> 2, and a loading platform 60 are provided on the upper turning body 20. A joint arm 70 is provided on the turning base 50, and a gripping wrist 80 (so-called clamp 80) is provided at the tip of the joint arm 70. The direction term “left, right, front, rear” described below is based on the driver's seat 30.
[0019]
As shown in FIG. 4, the loading platform 60 has a quadrangular shape and can be dumped as follows. That is, the rear rear surface of the bottom of the loading platform 60 and the rear portion of the upper swing body 20 are pin-connected by the first pin 61. The loading platform 60 has a convex portion 62 that is long in the front-rear direction at the bottom. The rod tip of the hydraulic cylinder 63 is pin-connected by the second pin 64 on the upper surface on the back side of the convex portion 62 and at a position ahead of the position of the first pin 61. The bottom end of the hydraulic cylinder 63 is pin-connected to the rear part of the upper swing body 20 by a third pin 65. Further, side bars 66 are erected on the left and right side surfaces of the loading platform 60 so as to be freely put in and out.
[0020]
As shown in FIG. 2, the articulated arm 70 is pin-connected to the turning base 50 with a base end and is connected to the tip of the first arm 72 by a first hydraulic cylinder 71 and a first arm 72. The second arm 74 can be raised and lowered by the second hydraulic cylinder 73, and the third arm 75 is pin-connected to the tip of the second arm 74 and can be raised and lowered by the second hydraulic cylinder 73. A clamp 80 is provided at the tip of the third arm 75 and can be opened and closed by a hydraulic cylinder (not shown).
[0021]
As shown in FIGS. 1 to 3, the turning base 50 and the joint arm 70 are located at the right side position of the driver's seat 30 on the upper turning body 20, the front position of the turning base 50, and the upper position of the drive source 40. An operation panel 90 on which various levers and instruments for operating the drive source 40 and the like are arranged, and an operator seat 100 for operating these various levers are provided.
[0022]
According to the above configuration, the crawler is caused to self-run and stop, the upper swing body 20 and the swing base 50 are swung and stopped, and the first to third arms 71 and 73 are moved by the first and second hydraulic cylinders 71 and 73, respectively. Long-range equipment such as utility poles and logs that exist within the reach range of the joint arm 70 even in mountainous forests with dense and narrow slopes and trees by raising and lowering 72 and 75, and opening and closing the clamp 80 Can be quickly loaded and transported on the platform 60 with good mobility.
[0023]
For example, when loading a short long piece of equipment or earth and sand, a partition plate is provided between the front and rear side bars 66 and 66 in advance, and the loading platform 60 can be dumped by a hydraulic cylinder so as to be loaded and unloaded. Of course, when the dumping operation is mainly performed, the left and right enclosure type loading platform 60A as shown in FIG. 5 is preferable instead of the side bar 66 loading platform 60 shown in FIGS.
[0024]
The operational effects of the first embodiment will be described more specifically.
(1) The example machine is a crawler type. For this reason, it can run without difficulty even in narrow and narrow slopes and forests with dense trees.
[0025]
(2) Moreover, the driver's seat 30 is mounted on the upper swing body 20 in the example machine. For this reason, even at the time of reverse drive, the upper swing body 20 can be turned to turn the driver's seat 30 in the reverse drive direction, and as a result, the reverse drive direction can be set as the forward drive direction. Therefore, operator fatigue can be reduced.
[0026]
(3) Moreover, the example machine is not a crane as in the prior art but is equipped with a clamp 80. For this reason, long equipment can be fixedly held in the space. Therefore, it is possible to eliminate the slip-through movement caused by manual work in the conventional narrow space.
[0027]
(4) Moreover, the example machine has a convex part 62 that is long in the front-rear direction on the bottom of the loading platform 60. That is, the left and right ends of the loading platform 60 have concave portions that are long in the front-rear direction. For this reason, even if a log that is easy to roll is loaded on the loading platform 60, the first log first falls into the recess 62 and is prevented from rolling. After that, the logs that are loaded one after another fall into the gaps between each other and prevent each other from rolling. That is, even if the example machine travels on a sloping ground, the log does not roll and workability is improved.
[0028]
(5) In the example machine, the rod tip of the hydraulic cylinder 63 is pin-connected by the second pin 64 to the upper surface on the back side of the convex portion 62. Therefore, it is possible to increase the tilt angle of the hydraulic cylinder 63 when the loading platform 60 is in the down position. Therefore, the hydraulic cylinder 63 can be downsized and the hydraulic pressure can be lowered. The reason is as follows.
[0029]
An example is a crawler-type cargo handling vehicle with an upper turning type. Therefore, even when the upper turning body 20 is turned, the third pin 65 is not less than the upper surface of the lower traveling body 10 (ie, the upper turning body) so that the portion of the third pin 65 does not collide with the lower traveling body 10 or the earth and sand on the crawler. It is necessary to provide it at a position (height higher than the lower surface of the body 20). On the other hand, the second pin 64 is desirably lower from the viewpoint of lowering the position of the center of gravity of the entire example machine. For this reason, a contradiction event occurs in which the tilt angle of the hydraulic cylinder 63 becomes small when the loading platform 60 is in the down position. The reason for the contradiction is that if the tilt angle of the hydraulic cylinder 63 with the platform 60 lying down is small, when the platform 60 is shifted to the upright position, the hydraulic cylinder 63 must generate a very large standing force. Because.

Other examples will be listed below.
[0031]
As shown in FIGS. 1 to 5, the platform 60, 60 </ b> A of the above example is a quadrangle, and is disposed on the upper swing body 20 from the rear surface of the driver seat 30 and the swing base 50 to the rear. If the following loading platforms 60B and 60C are used for such loading platforms 60 and 60A, the working efficiency can be improved. In addition, below, the same code | symbol is attached | subjected to the same element as the said FIGS. 1-5, and duplication description is abbreviate | omitted.
[0032]
(1) As shown in FIG. 6, the driver's seat 30 is disposed in the front part on the upper swing body 20, and the drive source 40 and the swing base 50 are placed in front of the driver seat 30 on the right side (or left side) in this order. In the example machine arranged rearward from the part, the loading platform 60B shown in FIG. 7 is arranged at the rear part on the upper swing body 20. That is, as shown in FIG. 7, the front edge of the loading platform 60 </ b> B extends along the rear surface F <b> 1 of the driver seat 30, the side surface F <b> 2 of the driver seat 30 of the turning base 50, and the rear surface F <b> 3 of the turning base 50. Configured. According to such a loading platform 60B, even long equipment having slightly different lengths can be loaded and transported at the same time with other long equipment without being left unstacked or repeatedly reciprocating.
[0033]
(2) As shown in FIG. 8, the driver's seat 30 and the turning base 50 are arranged in this order from the front to the rear on the upper turning body 20, and the drive source 40 is placed on the driver's seat 30 and the turning base. In the example machine arranged on either the left or right side of 50, the loading platform 60 </ b> C shown in FIG. 9 is arranged on the rear part on the upper swing body 20. That is, as shown in FIG. 9, the loading platform 60 </ b> C has its front drive source 40 side extending forward through the drive source 40 and the front loading seat 60 </ b> C extending forward. The edge S1 on the side of the turning base 50 is configured to extend to the rear S3 through the rear surface S2 of the turning base 50. It should be noted that providing the turning base 50 closer to the center of the vehicle body has an advantage that the reach range of the joint arm 70 at the left and right outer positions of the vehicle body is equalized. Therefore, in this example, the driver's seat 30 and the turning base 50 are provided in the center of the vehicle body, and a seat base 110 that is rotatable by a predetermined angle θ is provided on the left side. An operation panel 90 and a seat are provided on the seat base 110. 100. According to such a loading platform 60C, even long equipment having completely different lengths can be loaded and transported at the same time with other long equipment without being left unstacked or repeatedly reciprocated.
