LSW LIMITLOAD
LSW & SRW LIMITLOAD
Crane Overload detection
LSW LIMITLOAD units can be used on Overhead Cranes to effectively reduce the possibility of overload conditions. By clamping onto a static rope the unit can sense the load and switch out at a preset level. The units are fitted with 2 synchronous switches providing additional security of operation when connected in series to each other. Alternatively the 2 independent circuits can be connected via a safety PLC.
SRW LIMITLOAD units can be used to detect slack rope conditions or when a lifting beam has bottomed out. The units operate in the same way as the LSW units but require alternative wiring connections.
These units comply with the requirements of BS EN12077-2 & BS EN13849-2.
