This article will evaluate four types of lifting and hoisting equipment: roof-mounted hoists, truck-mounted conveyors, telescopic elevators and track hoists.
To adapt the hoist to the many different types of materials used on the roof, accessories are required at the cable end. These accessories include gravel buckets, hoisting forks, hoist slings, and platforms. Roof-mounted hoists can be powered by small gas engines with mechanical power transmissions, electric motors, LPG-powered engines and hydraulic drives.
