All DC Powered Cranes have a Limited Duty Cycle as per S.A.E. J706 (section 6.2) and is limited by the heat buildup in the motors and the declining charge of the batteries. Failure to provide adequate voltage and observe duty cycle constraints will result in premature motor failure. All DC Powered cranes need to have an auxiliary battery mounted as near to the crane as possible to insure adequate voltage. On Cranes 3200 lbs. and above it is required.
