る欠点があつた。 Install towers supporting power transmission lines, telephone lines, etc. in mountainous areas.
The base of a crane used when constructing on sloped ground such as a hilly area is made by excavating a wide area of sloping ground with an L-shaped cross section to form a flat surface, and then forming a flat surface with a wide area on which to attach the support legs of the crane. Build a foundation by pouring large concrete with sufficient volume.
The pedestal of the crane was fixed to the horizontal surface of this concrete foundation using mounting bolts, etc., and the tower was assembled and disassembled using this crane. For this reason, moving a large amount of earth and sand by excavating the sloped ground requires a long time, a huge amount of labor and cost, and a large amount of concrete must be used. Furthermore, once the tower assembly work is completed, it is necessary to remove the crane and restore the sloped ground by crushing the large amount of concrete foundation that served as the base of the crane. However, this method has the drawback that it requires the labor and expense of many people over a long period of time.

高低を有する地面に適用することができない。 Japanese Unexamined Patent Publication No. 55-56986 discloses that a post is installed vertically on a traveling device horizontally, a crane frame with triangular sides is provided under the post, and the drive device and the post are pivoted with a pin, and the post is attached to the bottom of the post. This crane is a slope-traveling type crane with a hydraulic cylinder attached to it so that it can travel on a slope and stop at a required point to perform work.It has a triangular crane mount in order to move up and down slopes that are sloped in only one direction. However, it cannot be applied to ground that has uneven heights in the vertical, horizontal, or diagonal directions.

Since the tail leg of the tripod is particularly long and the workbench is attached to it, the tail leg must be extended or retracted by turning the adjustment handle on each tripod, and the base mounting part of each tripod must be adjusted to the same height and height. It is impossible to adjust.

に大きく回転することが不可能である。 Utility Model Publication No. 53-814 is a traveling cargo handling device that fixes the vehicle body by extending multiple outriggers around the vehicle body to the sides during crane work, and fixes the vehicle body by attaching one end of the rope to the vehicle body. Fix the tip of the link plate that is pivoted to the box with a pivot pin to the winding drum of the pivot pin of the float, wrap the middle part of the float around the sheave, and lock the other end of the rope to the engagement end surface of the outrigger box. The structure is such that the float is fixed to a slider that is shaped like this, the bottom surface of the float is in contact with the ground in the working position, and the float can be rotated approximately 100 degrees around its pivot pin in the running position to retract the float and allow the float to travel on the vehicle body. However, the purpose and structure of the crane tower is different from that of standing vertically and fixing it on a sloped ground, and it is impossible to install it on a flat surface of a small concrete foundation with height differences set on a sloped ground. be. In other words, the tip of the link plate is operated by moving the legs at different inclination positions above or below the horizontal plane containing the shaft on small concrete foundations that are set at different heights on uneven ground with large height differences. Even if you try to erect the tower vertically on the leg mounts by placing each float, which is pivoted on the base with a pivot pin, on a small concrete foundation, the slider can be moved vertically by rotating the link plate around the pivot pin. The bottom surface of the float tilts due to collision with the engaging end surface of the float, making it impossible to rotate the float significantly upward from a horizontal plane including the pivot pin with the bottom surface level.

クレーンを提供するにある。 The purpose of this invention is to install the legs of a crane tower on an irregularly shaped slope with high and low heights, so that the tip of each of the four legs arranged in a cross shape on the leg mount of the crane tower can be mounted independently. and attach it to the shaft.
Four small concrete pieces corresponding to the number and setting positions of the legs of the crane tower's leg mount are fixed to the irregularly sloped ground by adjusting the movement up and down to a greater extent than the horizontal plane including the shaft attachment part. By simply moving a small amount of earth and sand, the foundations are placed at different heights along the uneven slope of the slope.
By fixing the legs, which are arranged in a cross shape and pivoted to the crane tower's leg mounts using mounting bolts, to the four concrete foundations using mounting bolts, etc., the sloped ground can be leveled and excavated to a horizontal surface. In order to create a depression for concrete pouring without removing a large amount of earth and sand, a concrete foundation can be created by simply removing a small amount of earth and sand from four locations, and when removing the crane tower after the steel tower is completed, the crane To provide a crane capable of restoring a sloped ground by crushing and removing the concrete foundation on the sloped ground with a small amount of human power in a short time after removing each of its four legs from the concrete foundation.

る。 As described above, in the present invention, the lower parts of the foundations of the legs 3, 4, 5, and 6 are attached to the leg mounts 11 horizontally provided at the lower end of the crane tower 2 by shafts 12, so that the lower parts of the bases of the legs 3, 4, 5, and 6 are mutually shaped like a cross when viewed from above. The turnbuckles 18 are attached to the upper parts of the bases of these crisscross-shaped legs 3, 4, 5, and 6 and the upper part of the leg mounting base 11, and the crisscross-shaped legs 3, 4, 5, and 6 are Four concrete foundations 7, whose tips extend upward and downward from the horizontal plane 13 including the shaft 12 and protrude along the slope 1;
8, 9, and 10, so when constructing a steel tower or the like on a slope in a mountainous area, there is no need to excavate a large amount of soil on the slope and transport it to another location. There is no need to invest personnel, and only a small amount of concrete is used.
After constructing a steel tower, etc., the crane can be removed, the concrete laid on the sloped ground can be crushed and removed, and the work of leveling the ground can be done quickly with a small number of people, which can provide great benefits when installing cranes on sloped ground. The four legs are pivoted to the leg mounts in a criss-cross pattern, so even if the crane tower were to topple over due to wind pressure blowing from the side, each leg would work together to firmly secure it to the four concrete foundations. Because of this function, there is no need for a particularly large crane tower base, making assembly and disassembly work easier.
