The cooling system is double cycle system, including engine middle-cooling cycle system and integrative radiator-sheath cycle system. Medium in hydrodynamic mechanical transmission is refrigerated by heat exchange.
Cab
The cab used a frame design. Heat and sound insulated. There are cool-warm air Condition and shock-absorbed operator's seat which can be adjusted to satisfy. Operator requirement in cab. Comfortable environment is established for operator.
Frame
A box-section design, made of variable-sections box beam which are welded with hardened and tempered abrasion-resistant alloy steel plate, equality intensity transverse beam and torsion tubes.
Body
Floor and sidewall made of hardened and tempered abrasion-resistant alloy steel plate. Body floor plate is heated by exhaust in order to avoiding cargo frozen in winter.
