Main Structure Schematic Diagram of Heavy – duty Towing and Lifting Integrated / Rotary Boom Type Wrecker
Only the classification of medium – and heavy – duty wreckers according to the conventional configurations of the upper body is introduced here. Based on the functions of the upper – body configurations of wreckers, their structures can be divided into two major categories: the integrated towing and lifting type and the rotary boom type.

Wireless and wired remote controllers; 22.Oil pump; 23.Power take – off (PTO);24. Front outrigger operation panel; 25.Front outriggers; 26.PTO operation switch; 27.Vehicle body and toolbox
Notes:
① For heavy – duty wreckers, the front outriggers can be classified into H – type horizontal – extending, A – type horizontal – rotating, and A – type outward – spreading types.
② The types, structures, configurations of various special devices and accessories of the wreckers described above may differ from what users require. The actual situation shall prevail.
