|This quarry at Horton-in-Ribblesdale has developed a system for mobile plant which engineers out the complicated and potentially hazardous procedure involved in traditional jump-starting vehicles.
The system works by simply connecting leads via two jack plugs (one positive and the other negative) into a receiver box on the vehicle, which are in turn connected to the batteries. The plugs have one male and one female connection at each end of the leads, making it impossible to connect them to the wrong terminal. Once the plugs have been connected, the procedure for starting and disconnecting is the same as with normal jump leads.
