1. Make sure the hoist is rated to lift the maximum height your job requires.
2. Make sure the hoist is rated to lift the maximum weight your job requires. A portable hoist usually means up to about a 2000 lb. capacity.
3. Take into consideration the lifting speed. If you are trying to lift and set your material into place you may want to look for a hoist that offers dual speeds. High lifting speeds are optimal for long lifting requirements but for short distances a slower hoist may be the answer.
4. Find out what your mounting options are on your construction site. Find a hoist that will easily mount to your location. How many workers will it take to successfully install the hoist at each location? If you are purchasing a hoist it is also a good idea to find out if there are other mounting options and how easily you can change from one to another. This will enable you to use your hoist on different projects. If you own your own scaffolding or routinely rent scaffolding it may be best to select a hoist that will mount to frame scaffolding or ride-up scaffolding. Some other mounting options are to an I-Beam or a hoist mounted on the ground with a cable and pulley.
5. Find out what your power options are. Some hoists operate on 110V power and others on 220V power. Some are also available in gasoline and/or diesel models. Hydraulic hoists powered by either gasoline, diesel or electric are also available.
6. Make sure you understand the proper way to use the hoist and inquire about safety features. Like with many types of construction equipment the operator may only receive basic training. Find out if the hoist has built in safety features that will ensure personal safety and give the hoist a long life. Some questions you can ask:
