New RBC-50000SPBW Self-Propelled Walk-Behind Mobile Crane is designed for indoor use where heavy components need to be lifted, transported, positioned, installed and assembled. Both eco-conscious and energy efficient, the unit can lift 50,000 pounds up to 240 inches high, while keeping facilities cleaner, quieter and safer (no fumes, no smell, no smoke). It features push-button controls, power steering, and a powered telescopic boom that can be maneuvered into hard-to-reach areas. Propulsion is DC battery-powered 48V, with solid-state control, and ten polyurethane wheels to spread loads and protect floors. The RBC series of cranes is available in a variety of capacities and sizes.
