Freight Elevators

A freight elevator, or goods lift, is an elevator designed to carry goods, rather than passengers. Freight elevators are generally required to display a written notice in the car that the use by passengers is prohibited, though certain freight elevators allow dual use through the use of an inconspicuous riser. Freight elevators are typically larger and capable of carrying heavier loads than a passenger elevator, generally from 2,300 to 4,500 kg. Freight elevators may have manually operated doors, and often have rugged interior finishes to prevent damage while loading and unloading. Although hydraulic freight elevators exist, electric elevators are more energy efficient for the work of freight lifting.

Stage and Orchestra lifts are specialized lifts for use in the performing arts, and are often exempt from some requirements[citation needed]. Local jurisdictions may govern their use, installation and testing; however they are often left out of local code enforcement provisions due to their infrequent installation.
