ความแตกต่างระหว่างรอกโซ่ไฟฟ้าและรอกสลิงไฟฟ้า

Electric chain hoists and electric wire rope hoists are both called electric hoists, but their prefixes represent that they are very different, and they have many differences in use. These two electric hoists are mainly composed of a magnetic brake motor, a reducer, a drum or sprocket, a wire rope or chain, a hook and electrical parts. The working principles of hoists are similar, but due to some differences in structure, the performance is different. They will be described below:

Motor: CD/MD wire rope electric hoist uses a conical rotor motor, while the chain electric hoist uses a cylindrical rotor motor. The braking principle of the side magnetic brake is the same. Under the condition of power on, the brake disc and the end The cover is separated, and under power-off conditions, the spring brakes, causing the brake to lock. In addition, among the two-speed รอกไฟฟ้า, the CD/MD wire rope electric hoist uses two lifting motors, while the chain electric hoist uses the same motor with double sets of windings.

Power transmission structure: The wire rope electric hoist uses a drum, and the wire rope is wound in the drum rolling groove in an orderly manner through the rope guide. The electric chain hoist uses a sprocket to guide the chain into the chain belt.

Scope of use: Wire rope electric hoists are often used in single-girder bridge cranes and single-girder gantry cranes, especially large-tonnage cranes above 5t. CD/MD wire rope electric hoists have an absolute advantage. รอกโซ่ไฟฟ้า are often used in cranes below 5t, especially in assembly lines, wind power and other projects, as well as light and small lifting equipment such as jib cranes and KBK cranes.

The main differences between wire rope electric hoists and chain hoists can be classified as follows:

1. Transmission medium: The transmission medium of the electric chain hoist is the chain, and the transmission medium of the electric wire rope hoist is the steel wire;

2. Lifting height: The lifting height of the electric chain hoist is low and is generally only suitable for lifting heavy objects of a few meters, while the รอกสลิงไฟฟ้า can lift heavy objects of tens of meters;

3. Lifting capacity: The load-bearing capacity of steel wire ropes can reach tens of tons, and are mostly used in large coal mines, bridges and other places; while electric chain hoists are often used for engineering lifting in small and medium-sized enterprises;

4. Running speed: The running speed of the electric chain hoist is relatively slow while the running speed of the wire rope electric hoist can be several times that of the chain;

5. Volume: Since the wire rope of the electric wire rope hoist is wound on the drum, the overall size is relatively large; the chain of the electric chain hoist is stored in the chain bag, and there is no huge drum, so the size is small.
