Special high yield strength angle steel in the mast, basic mast and fixing angles with eight pins clamping of mast from external and internal side pins interlocked, offer strong fastening of masts, good stiffness stability and high reliability and sustain higher wind loads. Ladder with safety cage and rest platform for the convenience of operator and maintenance crew on masts. Introduction trolley is provided for adding the mast, which is safe and efficient. Hook made for changing from four fall to two fall. Nylon pulley on hook provided for safety. The hoisting mechanism is designed to lift 5 tonne, having larger size rope cable drum. Option of non-variable frequency motors (three speed-pole changing motor) provide simple and reliable hoisting operation. According to the demand of users, the frequency altering and step less regulated, eddy-brake and electro mechanical brake or thruster, the brake speed regulated motor is adopted in hoisting mechanism. Safety features The safety features of these tower cranes include: Trolley limit switch stops the trolley movement when it approaches the jib end. Moment limit was integrated with over weight limit.
