Definitions

  • the invention relates to the transport of a crane undercarriage and a method that is used when transporting a crane undercarriage.
  • a tower crane in particular a tower crane, usually includes a so-called undercarriage.
  • the undercarriage forms the base of the crane's tower. It can be provided that the undercarriage is movable on the ground on which it stands. However, it can also be provided that the undercarriage rests firmly and immovably on the ground.
  • the undercarriage is composed of several components that must be connected and assembled together for the crane undercarriage to be used. When operational, the width of a crane undercarriage is too large to be transported on a truck and on a road. When operational, the crane undercarriage would protrude beyond the long sides of the truck.
  • the crane undercarriage must be dismantled into its individual components for transport - for example from one construction site to the next.
  • the individual components are loaded individually onto the truck using a crane and lashed there. This procedure requires numerous crane lifts and is therefore time-consuming and costly.
  • the invention is based on the object of specifying a device which enables a quick and cost-effective transport of a crane undercarriage.
  • a further object of the invention is to provide a method that enables a crane undercarriage to be transported quickly and cost-effectively.
  • components of a crane undercarriage can be connected to form an elongated transport unit.
  • the invention is based on the idea of using the components of a crane undercarriage to form an elongated transport unit.
  • the components of the crane undercarriage, which are used to form the elongated transport unit include at least one long support beam which extends in a first longitudinal direction, a first short support beam which extends in a second longitudinal direction and a second short support beam which extends in a third longitudinal direction extends.
  • the crane undercarriage that is not being used is in a serviceable condition.
  • the components of the crane undercarriage are connected to one another for use as the undercarriage of a crane.
  • the crane undercarriage is in transport condition.
  • the components of the crane undercarriage are at least partially connected to the elongated transport unit.
  • the first short support beam and the second short support beam form an overall beam.
  • the overall beam crosses the long support beam.
  • the claimed device set comprises at least a first connecting traverse, a second connecting traverse and a connecting element.
  • the connecting element is designed so that the first short support beam and the second short support beam are rigidly connected to one another in the transport state of the crane undercarriage by means of the connecting element Transport bar can be connected to each other.
  • the first short support beam and the second short support beam can be connected to one another in the transport state of the crane undercarriage by means of the connecting element in such a way that they extend one behind the other with respect to the second longitudinal direction. This results in the transport bar, which can be easily connected to the long support bar.
  • the first connecting traverse and the second connecting traverse are designed in such a way that they allow the long support beam and the transport beam to be connected to a rigid transport base frame of the transport unit.
  • the first connecting traverse and the second connecting traverse are designed so that a connection of the long support beam and the transport beam is possible in such a way that the long support beam and the transport beam lie next to each other in the direction transverse to the first longitudinal direction of the long support beam.
  • the transport beam and the long support beam form opposite outer sides of the transport base frame.
  • the first connecting traverse and the second connecting traverse expediently form opposite outer sides of the transport base frame.
  • the transport base is frame-shaped.
  • the transport beam, the long support beam, the first connecting traverse and the second connecting traverse advantageously form a frame.
  • the transport underframe can be used to transport the remaining components of the crane undercarriage that are not required to form the transport underframe. This makes it easy to transport the crane undercarriage.
  • the material costs and the transport costs for transporting the crane undercarriage can be kept to a minimum. It is not necessary to create a separate transport basket.
  • the device set can be used for existing crane undercarriages. It can be easily retrofitted.
  • the device set is a retrofit kit.
  • the transport undercarriage offers the advantage that the remaining components of the crane undercarriage can be accommodated in it, so that in order to load the components of the crane undercarriage onto a truck, only a single crane lift is required, with which the transport undercarriage is loaded onto the truck. Similarly, when unloading the components of the crane undercarriage, only a single crane lift is required. This brings great cost and time savings.
  • Lashing the components of the crane undercarriage is also much easier.
  • the components of the crane undercarriage stored on the transport undercarriage simply need to be lashed against the transport undercarriage standing on the truck. In this way, the transport underframe - and thus other components of the crane undercarriage - are already lashed to the truck.
  • the support bars include the long support bar, the first short support bar and the second short support bar.
  • connection of components of the crane undercarriage to the transport undercarriage using the device set according to the invention is also advantageous for storing a crane undercarriage.
  • the remaining components of the crane undercarriage which are not required to form the transport undercarriage, can be stored clearly and orderly on the transport undercarriage. It is therefore not necessary to store individual components separately from each other.
  • a crane undercarriage stored in this way is easy to find and easy to grab.
  • the transport unit formed in this way combines all parts of the crane undercarriage in a simple manner. In this way, the risk of individual components of the crane undercarriage being mixed with those of other crane undercarriages or other stored parts and/or being lost is minimized.
  • the first connecting traverse and the second connecting traverse are advantageously designed in such a way that they can be attached to the long support beam and to the transport beam exclusively by means of components of the crane undercarriage.
  • the components for fastening the first connecting traverse and the second connecting traverse to the long support beam and to the transport beam include bolts which are required in the operational state of the crane undercarriage to connect the components of the crane undercarriage.
  • no further components are required to form the rigid transport underframe other than the two connecting beams, the connecting element and the components of the crane undercarriage. This saves time and storage costs.
  • To transport the crane undercarriage and to form the transport undercarriage only the two connecting beams and the connecting element to the crane undercarriage must be brought along or present in a ready-to-use state.
  • the second longitudinal direction of the first short support beam corresponds to a fourth longitudinal direction of the transport beam.
  • the long support beam and the transport beam can expediently be connected to one another by means of the first connecting traverse and the second connecting traverse in such a way that the first longitudinal direction of the long support beam runs parallel to the fourth longitudinal direction of the transport beam.
  • the long support beam and the transport beam are at a distance from one another in the direction perpendicular to the first longitudinal direction. This makes it possible to create a stable transport base. Due to the distance between the transport beam and the support beam, the transport base frame can be designed with sufficient width to accommodate the other components of the crane undercarriage.
  • the width of the first connecting traverse is advantageously at least 0.3 m, in particular at least 0.5 m, in particular at least 0.7 m.
  • the width of the first connecting traverse is at most 2.5 m, in particular at most 2.0 m, in particular at most 1.5 m.
  • the first connecting traverse and the second connecting traverse expediently each have at least one attachment point, in particular at least one attachment point for a hook, preferably for a crane hook.
  • the transport base frame can be easily connected to a lifting means, in particular a crane hook.
  • the connecting element is expediently designed so that the first short support beam, the connecting element and the second short support beam can be connected to one another exclusively by means of components of the crane undercarriage.
  • the components for connecting the first short support beam, the connecting element and the second short support beam include bolts which are required in the operational state of the crane undercarriage to connect the components of the crane undercarriage.
  • the long support beam has a first length measured in the first longitudinal direction.
  • the transport bar extends in a fourth longitudinal direction.
  • the transport bar has a total length measured in the fourth longitudinal direction.
  • the connecting element is expediently designed so that a connection of the first short support beam and the second short support beam to the transport beam is possible in such a way that the total length of the transport beam is 90% to 110%, in particular 95% to 105%, preferably 100% of the first length of the long supporting beam. This means that the long support beam can be connected to the transport beam particularly easily and in a space-saving manner.
  • the device set comprises a transport frame for holding components of the crane undercarriage.
  • the transport frame is designed to be arranged on the transport base frame.
  • the transport frame enables simple and comfortable transport of the components of the crane undercarriage that are not required to form the transport undercarriage.
  • the support beams have recesses for receiving tower shafts of a tower frame of the crane undercarriage.
  • the tower shafts of the tower frame are accommodated in the recesses in the support beams.
  • the transport frame expediently has extensions.
  • the transport frame is designed in particular so that the extensions correspond to the recesses in the support beams when the crane undercarriage is in transport state.
  • the extensions of the transport frame engage in a form-fitting manner in the recesses of the support bars of the transport base frame. This means that the transport frame is stable and securely connected to the transport base.
  • the transport frame can also contribute to the stability of the transport base through its connection to the transport base.
  • the engagement of the extensions of the transport frame in the recess of the support bars secures the transport frame in particular against movement relative to the transport base frame in the direction of travel or against the direction of travel of the vehicle with which the crane undercarriage is transported.
  • the positive connection acts in such a way that movement relative to the transport base frame in the direction of travel or against the direction of travel of the vehicle with which the crane undercarriage is transported is prevented.
  • the positive connection advantageously prevents movement of the transport frame relative to the transport base frame in the first longitudinal direction of the long support beam.
  • the transport frame is expediently designed in such a way that the extensions of the transport frame can be inserted into the recesses in the support bars when the support bars are connected to the transport base frame. This makes it possible to easily connect the transport frame and the transport base.
  • the transport frame has attachment points, in particular attachment points for a lifting device, preferably for a crane hook.
  • the transport frame can be easily lifted from the transport base frame by means of a lifting device, in particular by means of a crane.
  • the support beams are first required to assemble the crane undercarriage.
  • the attachment points of the transport frame make it possible to first lift the transport frame from the truck and to place the transport frame with the other components of the crane undercarriage to the side. The transport undercarriage can then be lifted from the truck and placed in the location where the crane undercarriage is to be set up.
  • the transport frame is designed to accommodate components of the crane undercarriage, in particular to accommodate support bars and/or edge beams of the crane undercarriage.
  • the transport frame expediently has a crossbar.
  • the transport frame can advantageously be arranged on the transport base frame in such a way that the cross bar runs transversely to the first longitudinal direction of the long support beam.
  • the crossbar limits movements of the components accommodated in the transport frame in the direction of the crossbar.
  • the crossbar limits movements of the components held in the transport frame in the direction of travel of the truck.
  • the crossbar enables effective load securing. During a braking process of the truck, the crossbar prevents the components accommodated in the transport frame from moving unhindered in the direction of travel relative to the truck due to their inertia.
  • the device set according to the invention is advantageously part of a crane underframe set, which includes a crane underframe and the device set.
  • the method according to the invention is used to create an elongated transport unit for transporting a crane undercarriage.
  • the transport unit includes a transport base.

  • the corresponding components of the crane undercarriage are connected to one another in such a way that the transport undercarriage can be used to accommodate further components of the crane undercarriage. Because components of the crane undercarriage are used to create the transport unit according to the method according to the invention, material and transport costs for a transport unit for transporting the crane undercarriage can be saved.
  • the crane undercarriage includes a long support beam that extends in a first longitudinal direction, a first short support beam that extends in a second longitudinal direction and a second short support beam that extends in a third longitudinal direction.

This allows the transport beam and the long support beam to be connected to one another in a simple manner.
  • the long support beam and the transport beam are expediently connected to a rigid transport base frame of the transport unit by means of a first connecting traverse and a second connecting traverse.
  • the connection to the rigid transport base frame takes place in such a way that the long support beam and the transport beam lie next to one another in the direction transverse to the first longitudinal direction of the long support beam. This results in a stable and compact transport base.
  • the two beams lying next to each other can be used to support other components of the crane undercarriage.

Then access to the support bars of the transport underframe is free and access to the components of the crane undercarriage, which are required at the start of assembly, is possible quickly and easily.
