1.0 Introduction
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.
The Rice Lake Wheelchair Scale is a fully el
.86 m), and has a capacity up to 1000 lb (450 kg). The Rice Lake Wheelchair uses four corner-mounted, alloy
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.
The Rice Lake Wheelchair Scale comes equipped with a anti-slip rubber surfa

The following sections describe the correct installation procedures when installing the Rice Lake Wheelchair
Scale.
3.1 Unpacking Your Scale
The Rice Lake Wheelchair Scale comes shipped in a wooden two piece box. Place the unopened box in an open
area that has ample room for unpacking the scale.
Recommended tools needed to set up your scale inc

3.5 Cable Connections
Ten feet of 4-wire cable to connect the scale to the weight indicator is supplied with each scale.
The cable is pre-installed from the factory.
The cable must be routed to the indicator in a manner that will protect the cable from damage.
Cabling should exit the underside of the scale on the portable wheel side of the scale and not the ramp side(s).
When planning cable routing, leave a loose coil of excess cable under the scale to facilitate future lifting of the
scale for servicing or cleaning.
