Not only will you need to think about the amount of weight your hoist will typically be lifting, but you’ll also need to think about the preferred speed and the height you’ll need for the lift.

You should choose a hoist that can cater to both your present and future needs, which is why you should be critical when making your decision. http://www.baotgroup.com/electric-hoist/
