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.

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 work 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 due to the necessity of lifting the 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, and the width of the drum is set to be narrower than that of the main winding and the auxiliary winch. They are respectively installed 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 digs into the lower layer rope, and the state of the aligned and wound rope becomes a so-called turbulent winding state. There is a problem of promoting damage and shortening the life of the rope.

The purpose is to extend the life.
