LIS-SE: Load measurement and evaluation system that measures the voltage and current on all three phases of the hoist motor. Optional functions: load display in the push button pendant and load population recorder.

LIS-SV: this load indicator system offers all the functions of the LISSE system, but uses load measurement sensors in addition to motor current measurements. This system is an attractive proposition for systems with several hoists where the overall total load of all hoists needs to be limited. This system increases measurement accuracy. The load can be indicated either on the display in the pendant control or on a large load display
