MODULAR FREIGHT TROLLEY CRANE BRIDGE TYPE

摘要

The utility model refers to the lifting and transporting equipment, namely to supporting cargo trolleys, intended for lifting and moving cargo along the crane metal structure. The principal novelty of the utility model of the cargo trolley proposed is the metal structure of the frame, consisting of a central X-shaped link 1 (Figures 1, 3, 4), on which the segment modules of frame 2 and 5 (Fig. 1, 4). Each individual module can be equipped with a main or auxiliary lifting mechanism 3 including the upper pulley block 4 (Fig.1, 4), the electrical equipment elements 6 (Figures 1, 4) or used as the maintenance site 7 (Figure 1) . Thus, each segment module, together with the elements placed on it, is a separate, unified assembly unit. The motor-reducers of the movement mechanism 8 (Figures 1, 4) are attached directly to the wheel blocks 9 (Figures 1, 4) on which the trolley rests. The technical and economic advantage of the utility model is to reduce the weight of the trolley's metal structure, to shorten the design time by simultaneously developing different components of the same trolley, increasing the speed of the overall trolley assembly by allowing parallel assembly of its individual modules, simplifying the reconstruction of crane trucks by replacing the necessary modules, and operation of the trolley.
