Lift Profits, Lower Logistics Expenses with CLS Forklift Scales
The CLS Series forklift scale mounts directly to most Class II forklifts, saving material handling processes time and money. The CLS forklift scale system can be paired with a device for weight display through a cable or cableless connection. The weight display can either be a Rice Lake Weighing Systems indicator designed for the CLS or virtually through a device that supports the VIRTUi3 software application. There is also an optional USB, WPAN, and Wi-Fi connection available for connection to peripheral equipment.

- 9 to 26 VDC or 18 to 72 VDC power supply
- Cabled or cableless
- RS-232 serial port
- Wi-Fi
- WPAN
CLS-920i
The CLS-920i incorporates the flexibility, intelligence and programmability of the 920i in a smaller enclosure with a DC power supply for use on forklifts. The standard program offers weight indication, configuration, calibration and diagnostics specific to the CLS. Customize it for your application with an optional user program.
- Painted mild steel enclosure
- Backlit graphical LCD display
- Battery-backed time and date

CLS Virtual Solution
VIRTUi³
Weight data is displayed on a device using VIRTUi3 software, creating a virtual indicator. The CLS connects
to your device using RS-232, USB or WPAN. Choose between the CLS-M or CLS-IM configuration for static or in-motion use.
- Weight indication device (PC/tablet) is not included
- Consult factory to verify compatibility with your device
- WPAN connection available
- USB connection available
Cableless
The cableless option removes the coiled communications or power cable between the scale and the indicator. A rechargeable battery is secured to the scale, powering the scale and the paired wireless
modules provide communication.

WPAN
WPAN communication is a standard feature for the CLS-680 and is available as an external option for
the CLS-920i. It is also available in a communications/power box for the virtual solution.
Forklift Capacity Derating
During the initial scale installation, remind the customer that they must have an updated ID plate on the forklift stating the new lifting capacity and center of gravity information. This is required per OSHA rules and regulations.
| CLS Class II | 28-inch | 34-inch |
|---|---|---|
| Vertical center of gravity (VCG) of scale = | 8.06 in | 8.06 in |
| Horizontal center of gravity (HCG) of scale = | 2.09 in | 2.09 in |
| Effective thickness (ET) of scale = | 4.55 in | 4.55 in |
| Weight of scale = | 392 in | 420 in |
| Max capacity at 24-inch load center = | 5,000 lb | 5,000 lb |
