HOWO A7 Tractor Driving Type 6×4
Tractor truck and trailer is the transport vehicle for the short distance transport and long-distance transport of the trackless train. Tractors are used to pull trailers, sometimes for traction, traction aircraft or air cushion handling devices. Tractors are generally used in conjunction with trailers. Tractor and trailer connection way has two kinds: the first is a trailer after a half in front of the tractor segment on the traction saddle, to bear part of the weight of the trailer tractor at the back of the bridge, which is half hanged; The second is the front end of the trailer, which is attached to the rear end of the tractor. The tractor only provides the forward pulling force, dragging the trailer, but not withstanding the weight of the trailer, which is all hung.
