The Rice Lake Wheelchair Scale is a heavy-duty scale that easily accommodates wheelchairs with its large
platform size and easy-access ramp in either a single ramp (RL-350-5) or dual ramp model (RL-350-6). It
provides exceptional performance in applications where typical wheelchair scales are not large enough to meet
the needs of the patient.

steel shear beam load cells, with the cells recessed into the frame channels for protection. The Rice Lake
Wheelchair Scale offers two integrated handles and wheels for ease of portability.

Load cell cables are run through the main channels, and held down with replaceable cable ties near eac
eliminating the possibility of cable damage in portable applications.

The adjustable feet are used to allow leveling the scale to make up for minor floor irregularities. T
feet sit inside the foot keeper plates located on the front of the ramp.
