Clamp crane is a special crane, which has a weight limiter to prevent unsafe factors caused by overload, a height limiter to prevent the pulley or drum from being damaged by excessive lifting, and is widely used in outdoor and indoor environments, such as steel mills, shipyards, ports, storage yards and warehouses, for loading and unloading steel plates, section steels, etc.

Lifting mechanism of clamp crane

The lifting mechanism adopts an independent transmission system. The billets, coils and other objects are lifted and handled by clamps under the hooks. The clamp spreader includes mechanical and electric types. The mechanical clamp adopts the lever principle. Through self-locking, the clamp locking of billet or coil can be realized without external assistance. The electric clamp adopts an electric control system to realize the opening and closing of the clamp, and the size of the opening can be freely controlled.

Traveling mechanism

The crane traveling mechanism of the clamp crane is arranged on the same trolley frame, which is driven by the motor through the coupling to transmit the power to the reducer and drive the driving wheel to complete the vertical reciprocating motion. The end wheel is equipped with a rail cleaner, so that the obstacles on the rail surface can be automatically removed during the crane traveling, so as to ensure the safety of the crane.

Lifting mechanism

The lifting mechanism of the clamp crane is the same as the trolley traveling mechanism, with a separate driving device. The lifting mechanism is composed of motor, coupling, brake, gear motor, drum, pulley block, hook group, steel wire rope, etc. Driven by the motor, the drum is driven to lift the hook after the gear is decelerated. The transmission arrangement of the lifting mechanism is compact and easy to maintain, so as to ensure safety and reliability.

Bridge

The bridge is the main component and the main stressed component of the crane. The bridge is a double beam and double track structure, which is composed of main beam, end beam, walkway, railing, ladder and other auxiliary metal structures. The main beam is a box structure with sufficient strength, stiffness and overall stability. The reasonable layout of the traveling mechanism and electrical equipment of the clip on crane ensures the convenient movement of people in the bridge.
