Power Unit for Wheelchair Lifts and Other Applications

By Editor | October 7, 2013

Even though a component is targeted at a specific market, such as medical, it may be useful in a number of other applications with requirements similar to its primary market. Butler Mobility, for example, uses a high-quality, high-tech power lift for its inclined platform wheelchair lift. That same power unit can also be used for other applications and purposes, including material lifts, low-speed mixing purposes, packaging machinery, conveyors for a high-value product, and also as a control for batch or continuous processes, such as baking or heat treating.

The power unit has a rigid, double-decker chassis design that includes thick aluminum plates and durable fasteners. It also features a brake that safely holds the motor without power, as well as a gear box in a sealed unit. The power design also keeps the output from moving. The unit’s chain drive is rated for more than a 6,000 lb capacity.

Controls allow the system to operate on a 24-Vdc power supply. With the PLC and expansion module wired to three front-panel connectors, there are three switch circuits, including forward, stop and reverse applications.

An emergency stop switch circuit also passes through two of the connectors and disconnects the ac drive from the motor, releasing the brakes to hold the motor. With UL listed electrical components and a battery backup for at least five minutes of full-load operation, the power unit can be used by a variety of industries.
