There are occasions when a high altitude work platform is installed for the sailing work of ships and various structures. The high altitude work platform connects the bar materials such as steel bars to construct a frame of the hypothetical frame and places a large number of patriarchs on the frame. .

After the complaint is completed, the elevator workbench must be removed. If the height of the elevator workbench is high, a crane is needed to lift and transport the various members involved in the dismantling process.

The winch guide device according to the present embodiment is attached to the support frame 12 of the elevating platform so that the winch 10 can be used as a crane and thus the crane for conveying various members can be easily .

The strut frame 12 of the elevated workbench may comprise a plurality of vertical members 34 that are vertically upright, forming the columns of the false frame. A plurality of transverse frames and an inclined material are coupled between the vertical members 34 to form a framework of the elevating platform.

In this embodiment, as shown in Fig. 3, the four vertical members 34 will be described with respect to the supporting frame 12 in which the rectangular members are erected in a rectangular shape. A plurality of transverse frames and an inclined member can be coupled between the support frames 12.

The upper fixing table 14 and the lower fixing table 16 are spaced apart from each other along the longitudinal direction of the supporting frame 12. [ As shown in FIG. 4, the upper and lower fixing tables 14 and 16 are for fixing the winch guide apparatus according to the present embodiment to the support frame 12, And are separated from each other.

Both ends of the rotary member 18 are rotatably coupled to the upper fixing table 14 and the lower fixing table 16. The rotary member 18 may be made of a linear long bar, and both ends of the rotary member 18 are rotatably coupled to the upper fixing table 14 and the lower fixing table 16. The rotary member 18 is coupled to a boom frame 20 to be described later so that the boom frame 20 can be rotated about the support frame 12. [

The boom rope 20 is coupled to the rotary member 18 at one end so as to extend laterally in the rotary member 18. The boom rope 20 is coupled so as to extend in the lateral direction on the outer periphery of the vertically disposed rotary member 18. The boom frame (20) is coupled to the rotary member (18) and can be rotated about the support frame (12).

There is a fear that breakage may occur at one end of the boom frame 20 when the boom frame 20 is attached to the rotary member 18 in the form of a cantilever.
