Compared with wire rope electric hoist, ring chain electric hoist is light and flexible. The ring chain electric hoist is composed of an electric motor, a drive mechanism and a chain wheel, and the biggest difference between the electric hoist and the wire rope electric hoist is that the chain electric hoist adopts a chain instead of a steel wire rope. Lifting capacity is generally 0.5 to 60 tons, lifting height of 3~120 meters.
The weight of chain electric hoist: 240kg, 300kg, 0.5T, 1t, 2T, 3T, 5T, 10t, 20t, 25t, 30t, 35t. Speed of ring chain hoist: double speed, single speed, frequency conversion start, double speed conversion start, domestic technology has been able to achieve double speed electric hoist manufacturing requirements.
DHY type fast electric chain hoist, a hand chain hoist is light and convenient, and improved the manual chain hoists and enhance slow enough, DHY type electric hoist chain hoists and agglomeration advantages of electric hoist in a body, the disc brake motor as power cycloid reducer reducer, DHY series electric chain hoist has the advantages of compact structure, small volume, light weight, high efficiency, convenient use, reliable braking, simple maintenance.
Brake for chain electric hoist: side brake, cone type single brake, double brake (side brake + mechanical brake).
According to the hoisting mode, the chain hoist can be divided into two parts: right suspension, reverse reverse lifting and stage lifting.
The characteristics of electric hoist chain: the performance of advanced structure, small size, light weight, reliable performance, convenient operation, electric chain hoist is suitable for a wide range, very convenient for lifting heavy objects, loading and unloading work, maintenance equipment, lifting goods, electric chain hoist can also be installed on the air suspension I-beam, curve track, spin crane rail and fixed lifting hoisting heavy weights.
Ring chain electric hoist access power 110V-690V (domestic now can achieve), standard, usually 380V.
The switch control voltage of electric chain hoist is 24V/36V (if not through the built-in control switch transformer into 36V safe voltage will do harm to the body so that the control voltage of most electric chain hoist is 24/36V).
The standard configuration of the chain hoist must include a limit switch and a phase sequence protector
