The ring chain electric hoist is an electric lifting device that uses high-strength alloy steel chains as the lifting mechanism, featuring a compact structure and strong adaptability. 1. Power system Motor type: Three-phase asynchronous motor (for conventional industrial use), single-phase motor (for small tonnages), explosion-proof motor (Ex dIICT4) Power range: 0.25kW-15kW (corresponding to loads of 0.5-20 tons) 2. Transmission mechanism Gear reduction method: Planetary gears, helical gears (worm gear reducer with self-locking feature) Speed ratio range: 1:10 to 1:120 (based on the lifting speed requirements) 3. Load-bearing system Chain specification: G80 grade alloy steel chain Chain diameter selection: ∅6mm-∅10mm。
