Electric chain hoist is better than wire rope electric hoist, reasons are as follows:
1. For same capacity hoist, wire rope electric hoist volume is bigger several times than electric chain hoist. Especially lifting height is higher, rope drum of wire rope electric hoist will get bigger, which will reduce horizontal travelling length for same span compared with electric chain hoist.
2. For same capacity hoist and same height crane, lifting height of electric chain hoist is higher than wire rope electric hoist because of small volume of chain hoist.
3. Similar with first reason, big rope drum, during lifting, hook will move horizontally, and the higher lifting, rope will twine more round in drum, which cause hook large move horizontally, that makes lifting material not that accurate.
