1.0 Introduction
The CLS Series Cargo Lift scale is a rugged, dependable cargo lift scale that can withstand many years of
repeated use. When mounted on a forklift, the CLS Series can weigh, transfer and collect data in one efficient
operation. It saves operator time, equipment costs and eliminates the middle step.
The CLS Series is used with either Rice Lake’s 920i ® HMI digital weight indicator or the 420 digital weight
indicator.
