The required Working Load Limit (WLL) – The WLL of the hoist must be more or equal to the maximum weight that is to be lifted. Remember to factor in any extra rigging equipment required to sling the load (e.g. spreader bar, hooks, shackles etc.)
The required lifting height – Most hoists will lift between a maximum of 3 and 9 meters. Other custom-built sizes may be available.
The available power supply – Many hoists require three-phase power for operation. Some are also available for single phase power use.
The operating environment – Take into consideration: humidity, extreme temperatures (both hot and cold), work environments high in salt or other corrosive chemicals, heat from sun exposure. Extreme or corrosive environments may accelerate wear and tear on electric chain hoists.
The frequency of use – Take into consideration the number of starts per hour, number of hours used per day, and number of days used per year. Also consider the type of work the hoist will be doing: moving back and forth along a beam or constantly lifting to its capacity in both weight and height.
