The Elfatek OCS-CU02 dual input overload control indicator works together with the load cells and connects easily to industrial control devices. This robust control unit for cranes has 8 relay outputs and, on double hoist or double hook cranes, measures the load on each hook separately as well as the total load.
- 2 load cell inputs, 8 relays (RL1–RL8) with adjustable switching points
- 2 analog outputs and 4 digital inputs
- RS232 and CANBus communication
- Load per hook and total load for double hoist cranes
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.
