Electric rope hoist mainly refers to electric wire rope hoist. It is widely used for lifting, moving, loading and loading material. It is also applied to building construction enterprise, bridge construction, electric power, and road, mine etc. As a small and light duty electric hoist, wire rope hoist has advantages as compact structure, light weight, small volume, universal parts, simple operation. It can be installed on the I-beam steel individually, it can also be used together with single or double girder overhead crane, gantry crane and jib crane. Ellsen Group, a famous electrical hoists supplier, produces types of wire rope hoists with attractive quality and price.
How does lifting mechanism work?
Lifting motor drives the rope drum to rotate through coupling and reducer, and makes wire ropes drive the hook device to up and down.
When the lifting height is more than 6m, a jaw coupling is used to connect motor shaft and input shaft of reducer; more than 9m, intermediate shaft and rigidity connector are increased; more than 18m, a supporting structure is needed to increase the rigidity of intermediate shaft and ensure stable rotation.
Reducer adopts helical gear. The gear and shaft are made of alloy steel or high quality carbon steel, and are through suitable heat-treatment to ensure reliability and long-term service life. The box body and box cover are made of cast iron with good property of shock absorption and reliable sealing.
How to maintain wire rope?
Wire rope is an important part of the lifting mechanism, so it is necessary to maintain wire ropes well. Wire rope should be protected from damage and corrosion caused by physical and chemical factors. When the rope rolls and disentangles, avoiding knotting and twisting. When the ropes are cut off, measures should be taken to prevent rope strands from loose. Good lubrication for wire rope is necessary. The lubricant should meet the wire rope standard. Daily check for wire rope is a must. It includes the fixed connection of end part, wire rope of balance wheel and safety judgment.
What to do if wire ropes are in disorder?
Rope guide is small but very important. With rope guide, wire ropes can arrange in order, if this item is in trouble, disorder happens. Rope guide is easy to damage, if damaged seriously, it can’t guide the rope, so it is needed to change a new guide-rope device. For lifting work, dragging in sideway can badly damage the rope-guide, thus the wire rope should be kept vertical straight.
