LDA type electric single beam bridge crane is used with electric hoist CD, MD type, a lightweight crane with rail operation, which is also one of the best-selling models on the market. This product is a general purpose crane. Electric single-beam bridge crane has the characteristics of light weight, small size, compact structure, variety specifications, smooth operation, etc., and is widely used in machinery manufacturing, assembly workshop and warehouse.
Structure Characteristics and Working Principle
Electric single-beam bridge crane composed of the bridge frame, lifting mechanism, car operation, car operation and electrical four main parts, the use of trolley type wire rope electric hoist as the lifting mechanism.
Main Beam
The electric single-beam bridge crane adopts three-beam structure, the main beam and the end beam are connected with high-strength bolts, in order to prevent the operating mechanism from traveling to the limit position, the left and right sides of the main beam are provided with buffer blocks.
Hoisting Mechanism
The electric hoist used in the lifting mechanism is jointly designed and produced by professional manufacturers. The structural
Electrical Equipment
The operation of each mechanism of the crane is operated by the ground operator. The lifting mechanism of the single-beam crane is completed by the electric hoist. The rated voltage is 380V, the rated frequency is 50HZ, the insulation level is F, and the protection level is IP44.
Brake
The brake is cone brake.
Motor
The reducer adopts electric hoist transmission.
characteristics of the electric hoist are detailed in the manual.
Vehicle
