Abstract
The load limiting device for hydraulic cranes comprises load sensing means incorporating two way two position response valve (10) which picks up pressure signal from end of hydraulic cylinder (4). Response valve connects with pump (14) and send line (11) through which signal is transmitted. When signal from cylinder (4) exceeds maximum rated capacity of crane valve opens and stops fluid flow to lift cylinders.
