Zhonggong supplies a full range of components and parts for crane and hoist, such as crane motor, crane brake, wire rope, crane reducer.
Crane control handles can be a wire pendant, realizing wireless remote control, joystick control, or radio control.
Crane hook is one of the most important spare parts for a crane. With the help of pulleys, the crane hook group can realize the hoisting and lifting function.
It is generally installed on the high-speed shaft of the mechanism to reduce the braking torque.
It is a crane operator room with console for crane control.
We offer types of electromagnetic chucks with different sizes to meet various needs of your electromagnetic overhead cranes.
For your different needs, we provide crane motors of various well-known brands.
It is a metal groove or ridge that holds, guides, and reduces friction for a moving device and a steel-striped line used for a running trolley.
It is to reduce the high speed of the motor to the working speed required by each mechanism.
Crane wheels are used for sustaining the crane. The wheel and the angle bearing housing are assembled together to form a wheel group.
The gear motor is 3-in-1 drive equipment which combines motor, reducer/gear box and brake into one machine.
It features large grasping force, which is suitable for loading and unloading of large ore, pig iron block, scrap steel, garbage, iron powder, straw, slag and other materials.
Simple structure, quick response, safe, reliable, and automatic control.
It is a part of the hoisting mechanism used to wind the steel wire rope.
It is divided into fixed pulley and movable pulley block.
It’s constituted by steel wire, rope core and grease, which is used for lifting, towing, straining and load bearing.
The lifting mechanism includes brake, motor, reducer, drum and pulley block. The motor drives the drum to rotate through the reducer, so that the steel wire rope can be wound on or unwound from the drum to lift the weight. Trolley frame is used for supporting and installing hoisting mechanism. Trolley running mechanism and other components are usually of welded structure.
The driving modes of crane operating mechanism can be divided into centralized driving and separate driving. Small and medium-sized bridge cranes mostly adopt the "three in one" driving mode composed of brake, reducer and motor. In order to facilitate installation and adjustment, the driving device of ordinary bridge cranes with large lifting capacity often adopts universal coupling.
The bridge is composed of main beam and end beam, which is divided into single main beam bridge and double beam bridge. The main beam is rigidly connected with the end beam, and wheels are installed at both ends of the end beam to support the bridge to run on the elevated rail. A track is welded on the main beam for the operation of the lifting trolley.
