Elevators are common sights in commercial buildings, but when you have a smaller structure needing better accessibility, the Freedom Commercial elevator may be what you need.
Using a hydraulic system, the Freedom Commercial elevator is able to support up to 1,400 pounds and moves at 30 feet per minute. Large enough for wheelchairs, most furniture, and equipment, the Freedom Commercial's car is 48 by 54 inches and 84 inches tall. Compliance for commercial structures is particularly crucial, and this commercial elevator meets Limited Use Limited Application (LULA) requirements for the United States and Canada and is ADA compliant. This type of commercial elevator, however, is not large enough for gurney access.
Installation for the Freedom Commercial takes 10 to 15 days. During this procedure, the car needs a functional telephone jack and smoke and fire alarms.
The Freedom Commercial is one type of elevator offered by Nationwide Lifts, but commercial systems in general may be hydraulic or traction. The Freedom Commercial uses a hydraulic system, which is quiet and moves the car up from the bottom. Installation for this type of elevator involves more than adding a hoistway, however. Planning for the Freedom Commercial must also take into account the pit and machine room.
Inside your building, an elevator like the Freedom Commercial is above a pit and attached to a fluid-driven piston mounted inside a cylinder, which is connected to a system of a tank, pump, and valve. The pump moves hydraulic fluid from the tank into a pipe, where a valve is located, connected to the cylinder. When the valve is closed, the fluid goes into the cylinder, which pushes the piston and the car up. Changing the fluid regularly is part of maintaining a commercial elevator.
Commercial elevators may use a traction, or electric, system, which may be geared or gearless. In either case, traction elevators have a few advantages. First, no machine room is needed, and second, the system is overall better for the environment. No hydraulic oil is used, and traction elevators tend to use one-third of the power that hydraulic systems need. Nevertheless, a traction system has a car suspended in a hoistway and is not the safest in the event of an earthquake or similar natural disaster.
