Function of Every Part:

The tow body is made up of sub-frame, under-lift, boom, boom rotary device, outriggers and toolbox.

(a) Sub-frame is the foundation for every tow body parts. The weight of tow body could be equally distributed to sub-frame, which improved the force bearing condition of chassis. It transfers the load to outriggers while lifting.
