1. Structure: Level-luffing portal crane is composed of lifting mechanical components, luffing mechanism and traveling mechanism. Lifting machinery components include main beams, lifting mechanisms, hooks, etc.
2. Lifting mechanism: The lifting mechanism consists of motor, reducer, brake and reel. The motor converts electrical energy into mechanical energy through the reducer and drives the drum to lift the wire rope to realize the lifting movement of the lifting object.
3. Luffing mechanism: The luffing mechanism is used to realize the luffing motion of the crane, allowing it to move and turn in the horizontal direction. The luffing mechanism usually consists of a motor, gears, racks and rollers. The electric motor drives the rack movement through the gear transmission system, thereby moving the crane in the horizontal direction.
4. Traveling mechanism: The traveling mechanism is used to realize the traveling motion of the crane. It usually consists of electric motor, gears and tires. The electric motor drives the tires to rotate through a gear transmission system, allowing the crane to travel in a horizontal direction.
5. Control system: Level-luffing portal crane is also equipped with a control system to control the movement and operation of the crane. The control system usually consists of buttons, remote controls and sensors, etc., which can realize the lifting, luffing and walking operations of the crane.
The level-luffing portal crane realizes operations such as hoisting, lifting, luffing and walking of heavy objects through the coordinated movement of the hoisting mechanism, luffing mechanism and traveling mechanism. The control system plays the role of controlling and monitoring the movement of the crane to ensure the safety and accuracy of the operation.
