1. Equipped with both superstructure and chassis engines with great economy and low cost. 2. Excellent lifting performance: 1) 5-sectio, elliptic boom with fully extended length of 43m 2) Adding 0.5m wire rope of height limiter, Max. lifting height for main boom is up to 42.67m. 3) Dividing of boom section is more reasonable. The medium-long booms at the same radius and lifting capacities are longer than those of other similar products. The boom base section has surpassed other similar products in lifting performance. 4) Equipped with big span outriggers, being of good stability in crane operating, 3. Outstanding advantages: 1) Both superstructure and chassis are provided with world top grade Cummins engines, the engine type of chassis is NTC-350, which has strong power reserve, and is better than other similar products. 2) Equipped with British LIPE clutch, imported German ZF steering gear and pump. 9-step gear transmission with German ZF technology. 3) Optional Steyer driving axles or self-made driving axles by using German Kesseler technologies are of good bearing capacity, big rigidity and automatic compensation for braking clearance. 4) Imported hydraulic piloted proportional control valve, solenoid control valve and balance valve. 5) Equipped with standard cool & hot air conditioners for superstructure and chassis. Hydraulic system adopts new leak-proof joints and pipe lines. Max. lifting capacity:8 0(t) Max. lifting height:42.67 (m) Power of engine:261Kw/2100r/min self-weight:46000 ( Kg )
