A load cell shackle warns crane operators of excessive crane loadings when lifting heavy equipment for a mining company in South Australia.
As the crane operator is unable to see if the 70t mantle is fouling on other equipment further down the shaft during the lifting operation, the load cell shackle is proving to be invaluable by eliminating the chance of damage caused by the mantle suddenly “letting go” after being snagged during lifting.
The load cell shackle outputs the load reading using a wireless interface back to a control box containing a digital weight indicator fitted to the crane cab. In this application, a load in excess of 72t triggers a setpoint relay to activate a local alarm to warn the crane operator of excessive loading which indicates a fouling problem.
Due to the success of this application, the client also requested a smaller load cell shackle with a load capacity of 8.5 t for use on a smaller crane.
