This counter balance design is ideal for die loading, machine feeding, and for loading and unloading trucks. An ergonomic handle features easy-to-operate throttle with infinite adjustment of forward and reverse speeds, lift/lower controls. When actuated, the emergency reverse belly switch instantly reverses direction and moves the unit forward (away from the operator) until the switch is released or after five seconds have elapsed. The built-in safety circuit will automatically disable the entire unit if the emergency reverse belly switch is activated for more than 5 seconds after which the unit must be re-set to return to normal operating conditions. Stacker rolls smoothly on poly-on-steel steer & load wheels. Features 0.7 KW drive and 2.0 KW lift motor. 3-4 hour operation at full charge - 8 hours when used intermittently.
