The LD single-beam crane is mainly composed of four parts: metal structure, operating mechanism, hoisting mechanism and electrical equipment. Our editor will give you a brief introduction to these four parts:
1. LD electric single beam crane Metal structure
The main girder of the single-beam crane adopts a U-shaped groove formed by steel plate rolling, and then is assembled and welded with an I-beam to form a box-shaped main girder. , The beams can be disassembled and transported, and high-strength bolts are used to form a bridge during installation.
2. LD electric single beam crane Operating agency
The operating mechanism of a single-beam crane generally adopts a separate driving mode, and the driving and braking are completed by a conical motor, and the transmission adopts an "open-close" type gear transmission.
3. LD electric single beam crane Lifting mechanism
Single-beam cranes generally use wire rope electric hoist as the lifting mechanism, and the electric hoist can be of type CD1 or MD1. The electric hoist is hung on the I-beam under the main beam and walks left and right by the trolley.
4. LD electric single beam crane Electrical equipment
The motor used in this product is a conical motor with a brake device. The control box is a dedicated electrical control box (when operating on the ground) or a protective cabinet plus cam controller operation control (when operating in the driver's cab). The running speed when operating on the ground: 20m /min; 30m/min; control room operation is 45m/min; 60m/min. The crane is equipped with safety devices and has high reliability.
