When you purchase hoist, parameters need to offer as followings:
1. Lifting capacity
2. Lifting height
3. Working class (how many hours the crane will work in one working day)
4. The Voltage, frequency
5. The beam model to match (I beam or box type beam)
6. Whether exist long traveling mechanism?
7. Hoist model (wire rope hoist or chain hoist, if chain hoist, manual type or electric type, whether need trolley)
8. Working environment(temperature, humidity, elevation)

When you purchase complete crane, parameters need to offer as followings:
1. What kind of crane? (overhead crane, gantry crane , suspension crane, lifting mechanism is hoist type or winch type)
2. What is the purpose of crane? or what you lift with crane?
3. Lifting capacity
4. Span (you can supply workshop layout or the workshop length and width)
5. Lifting height
6. Working conditions (how many hours the crane work in one day, how about weight you lift at one time? how long time only in one working period? how many the cycle times in one day?)
7. Working environment (temperature, humidity, elevation)
8. The Voltage, frequency
9. Wind speed (when need gantry crane)
10.Do you have some special functions requests? (Working area, intelligent functions etc.)
