2.The distance between the bottom of I-beam to the center of the electric hoist hook : you should pay more attention to the distance of the up-and-down hook.Because it have certain specific request for the electric hoist hook spacing. If you have strict requirements on hook spacing, low building height can meet your requirements.
3 Voltage: there are different types of voltage for electric chain hoist in various industry. The domestic load is 220V and industrial electricity 380V, and there are some non-standard power supply,440 v, 60 hz, 380 v, 60 hz.
4 Hoisting height: it has strict requirements on hoisting height as a kind of promotion tool. So you should choose the height of lifting heavy objects according to the height of the building. The regular hoisting heights are 6, 9, 12, 18, 24, 30m, and you can choose non-standard design according to user requirements on special occasions.
5.Motor power: different hoist uses different motors.
