The LP cantilever single girder crane operates by the coordinated action of the trolley running mechanism and the hoist running mechanism, allowing the hook to move in three-dimensional space, thus achieving the lifting and transportation of goods. Specifically, the trolley running mechanism drives the crane to move longitudinally along the factory track, while the hoist running mechanism drives the lifting mechanism to move transversely along the main beam track. The lifting mechanism, powered by an electric motor, drives the drum to raise and lower the steel wire rope or chain, achieving the vertical movement of the hook to lift and transport the goods to the designated position.
Main Beam Structure: The cantilever single girder design is adopted, with the main beam typically composed of I-beams or other types of steel and steel plates. This structural form provides good stability and load-bearing capacity during operation, while also reducing the weight of the crane, which lowers the requirements on the factory structure.
Trolley Mechanism: This includes an electric hoist or other lifting devices, installed at the cantilever position of the main beam. The trolley moves along the track of the main beam, achieving the horizontal movement of goods. The lifting mechanism drives the hook through steel wire ropes or chains, completing the lifting and lowering actions of the goods.
Bridge Running Mechanism: Consisting of a motor, reducer, wheels, and other components, this is installed at both ends of the crane. The bridge running mechanism drives the crane to move longitudinally along the factory track, allowing the crane to cover the entire working area.
Electrical Control System: Used to control the operation of each mechanism of the crane, including starting, stopping, and speed adjustment of the motors. Advanced PLC control systems are typically used, which are characterized by ease of operation, high control accuracy, and good safety performance.
Used for lifting and transporting various mechanical equipment and components, such as engine blocks, large gears, etc. It can also cooperate with production lines for precise assembly tasks.
Used for lifting and transporting high-temperature metal billets, steel, and other heavy items, but generally not used for lifting molten metals or red-hot metals.
Capable of lifting, stacking, and transporting various goods, facilitating storage and turnover of goods. It is especially suitable for use in low-ceiling warehouses with limited space.
Suitable for lifting and transporting large electronic equipment, components, etc. Due to its high positioning accuracy, it can meet the high-precision requirements for equipment handling in electronics production workshops.
In assembly workshops such as automobile manufacturing or furniture manufacturing, it can lift and transport components to designated positions, making it easier for workers to assemble and improving assembly efficiency and quality.
The cantilever single girder design is used, with the main beam typically composed of I-beams or other structural steel combined with steel plates. This structure provides good stability and load-bearing capacity during operation while reducing the weight of the crane, which in turn lowers the requirements for the factory building's structure.
This includes an electric hoist or other lifting devices, installed at the cantilever position of the main beam. The trolley moves along the track of the main beam to achieve the horizontal movement of the load. The lifting mechanism drives the hook through steel wire ropes or chains, completing the lifting and lowering movements of the load.
Consisting of a motor, reducer, wheels, and other components, this is installed at both ends of the crane. The bridge running mechanism drives the crane to move longitudinally along the factory track, enabling the crane to cover the entire working area.
This system controls the operation of each mechanism of the crane, including starting, stopping, and speed adjustment of the motors. It typically uses an advanced PLC control system, characterized by ease of operation, high control precision, and excellent safety performance.
