位置に設置される。2. Description of the Related Art A working vehicle such as a crane truck is transported by self-propelled movement or mounted on a trailer or the like. During transportation, the vehicle travels on public roads. At this time, transport restrictions on the vehicle body are specified by laws and regulations. Further, a wire rope type crane is usually equipped with three types of winches on the upper revolving structure: a main winch for performing a main suspension operation, an auxiliary winch for performing an auxiliary suspension operation, and an undulating winch for raising and lowering a boom.
However, this type of crane is also used for excavation work by attaching a grab bucket or clamshell bucket to a wire rope in addition to crane work such as moving a suspended load. When used for excavation work, in addition to raising and lowering the bucket, opening and closing operations are also required, and crane work is also required as an auxiliary work for excavation work. Therefore, the above-described main winch, auxiliary winch, and undulating winch are required. In addition, additional winches have been added. The main winch and auxiliary winch have a wide winch drum so that the rope can be wound long because of the necessity of lifting the lifting load and securing the excavation depth. Are installed in series in the front-rear direction. The drum of the hoisting winch is used for the hoisting operation of the boom, but the width of the drum is set to be narrower than that of the main winding and the auxiliary winch. They are arranged on the upper revolving unit with both ends of the rotary shaft of the winch drum supported by bearing members. As shown in FIG. 13, the auxiliary winch B to be added is installed at the lateral position of the undulating winch A with both ends of the rotating shaft of the winch drum 1 supported by bearing members 5 and 6 different from the undulating winch A. Is done.

る。As described above, the width of the crane is also limited by the transport dimensions of the vehicle body. Therefore, when an auxiliary winch is added, the width of the vehicle body defined by the transport dimensions is limited. The width of the drum of the auxiliary winch must be set accordingly. Furthermore, since the auxiliary winch is arranged in parallel with the undulating winch, it is difficult to set the width of the winch drum wide. To secure the rope length for crane work, it is necessary to wind the rope in multiple layers in the radial direction of the drum. There is. However, when a rope is wound in multiple layers, when a load is applied to the rope, the upper layer rope bites into the lower layer rope, and the state of the aligned and wound rope becomes a so-called turbulent winding state, and the rope rubs, bends, etc. There is a problem of promoting damage and shortening the life of the rope.
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention secures a dimension in the width direction of a drum of an auxiliary winch to be added, prevents multilayered winding of a rope wound around the drum of the auxiliary winch, and extends the life of the rope. It is intended to aim at.

In the winch support device according to the fourth aspect, the second bearing member is formed so as to be accommodated within the width of the support leg of the first bearing member when the second bearing member is fitted to the first bearing member. Therefore, when the second winch is added to the first winch, the width of the winch can be increased by the width of the second bearing member, and the number of winding layers of the wire rope to be wound can be reduced. The generation of winding can be suppressed, and the service life of the wire rope can be extended. The additional winch device according to any one of claims 5, 6 and 7 includes the second bearing member having the fitting recess that can be fitted to the fitting projection of the first bearing member on the second winch. When the second winch is added to the first winch, the fitting recess of the second bearing member supporting the second winch is fitted to the fitting projection of the first bearing member. Attachment is possible, space in the width direction is saved by the width of the fitting protrusions and recesses, and the width of the second winch can be increased by this space, so that the number of winding layers of the wire rope to be wound can be reduced. In addition, the occurrence of turbulence can be suppressed, and the service life of the wire rope can be extended. The method of attaching an additional winch according to claim 8, wherein the fitting of the second bearing member attached to the second winch is fitted to the fitting projection of the second bearing member on the guide portion provided on the first bearing member. Since the fitting is performed by fitting the mating recesses, the mounting work can be easily performed, and the workability is improved. According to a ninth aspect of the present invention, in the method for mounting an additional winch, the supporting protrusion of the second bearing member is brought into contact with a guide portion provided on the first bearing member, thereby forming a fitting protrusion of the first bearing member. Since the fitting recess of the second bearing member is guided and aligned in the portion, the second winch can be easily attached to the first winch, and workability is improved.

During transportation, the vehicle travels on public roads. At this time, transport restrictions on the vehicle body are specified by laws and regulations. Further, a wire rope type crane is usually equipped with three types of winches on the upper revolving structure: a main winch for performing a main suspension operation, an auxiliary winch for performing an auxiliary suspension operation, and an undulating winch for raising and lowering a boom.
However, this type of crane is also used for excavation work by attaching a grab bucket or clamshell bucket to a wire rope in addition to crane work such as moving a suspended load.

チAの側方位置に設置される。When used for excavation work, in addition to the vertical movement of the bucket, opening and closing operations are also required, and a crane operation is also required as an auxiliary work for the excavation work. In addition to the undulating winch, an auxiliary winch has been added. The main winch and auxiliary winch have a wide winch drum so that the rope can be wound long because of the necessity of lifting the lifting load and securing the excavation depth. Are installed in series in the front-rear direction. The drum of the hoisting winch is used for the hoisting operation of the boom, but the width of the drum is set to be narrower than that of the main winding and the auxiliary winch. They are arranged on the upper revolving unit with both ends of the rotary shaft of the winch drum supported by bearing members. As shown in FIG. 13, the auxiliary winch B to be added is installed at the lateral position of the undulating winch A with both ends of the rotating shaft of the winch drum 1 supported by bearing members 5 and 6 different from the undulating winch A. Is done.

助長し、ロープの寿命を低下させるという問題がある。As described above, the width of the crane is also limited by the transport dimensions of the vehicle body. Therefore, when an auxiliary winch is added, the width of the vehicle body defined by the transport dimensions is limited. The width of the drum of the auxiliary winch must be set accordingly. Furthermore, since the auxiliary winch is arranged in parallel with the undulating winch, it is difficult to set the width of the winch drum wide. To secure the rope length for crane work, it is necessary to wind the rope in multiple layers in the radial direction of the drum. There is. However, when a rope is wound in multiple layers, when a load is applied to the rope, the upper layer rope bites into the lower layer rope, and the state of the aligned and wound rope becomes a so-called turbulent winding state, and the rope rubs, bends, etc. There is a problem of promoting damage and shortening the life of the rope.
