Key Features of Truck Crane with 8-Speed Gear Box

• The crane is equipped with 8-speed gearbox which changes gear smoothly and is of simple structure and makes maintenance convenient.
• The crane is fitted with a 40m long hexagon-section boom which is made of high-strength steel, so the boom has strong resistance to bending and torsion.
• The unique manual full proportional control incorporates the advantages of traditional lever control and electric-hydraulic pilot control. It not only reserves the merits of safety & reliability of original control structure and low maintenance cost, but also realizes that the working speed of actuating mechanism is only proportional to the opening degree of control valves rather than affected by the load.
• The slewing mechanism has the functions of protecting the crane automatically when the crane is overloaded, reducing the impacts, and activating hydraulic brake when the hydraulic control valve is in neutral position as well as free swing. In addition, it can automatically make boom, wire rope and lifted load slew simultaneously, and minimize the sway of boom and load while the crane starts or stops quickly, and accelerates or decelerates slewing.
