The Elfatek OCS-CU01 series overload control indicator works together with the load cell and connects easily to industrial control devices. It is a sturdy, high-quality control unit for cranes with 4 relay outputs: it reads one load cell, shows the load and switches the relays to warn and stop hoisting at the limits you set.
- 1 load cell input, 4 relays (RL1–RL4) with adjustable switching points
- 1 analog output (voltage or current)
- RS232 or CANBus communication (optional)
- Simple calibration with the crane rope unloaded
TMA supplies Elfatek crane safety equipment in Egypt as Elfatek’s agent, with selection, installation, calibration, spare parts and after-sales support from our crane engineers.
