Types of Elevators
Freight elevators are of two types, hydraulic or traction. Traction lifts are fitted with a motor which is electrically powered which pulls a strong steel cable placed in a grooved pulley whereas hydraulic lifts have a piston which pushes the lift upwards.

Most of them have two doors that are manually operated and then inside of them I such are finished with strong materials which can withstand wear and tear. In some cases the vehicles in which the goods are transported are loaded directly into the elevators, there are lifts which are specially designed for this purpose.
