DRC-MP radio controls, a better substitute to wire-connected controls, provide control over hoists, cranes, industrial machinery, doors, and installations, with a choice between the DRC-J joystick transmitter and the DRC-10 key-actuated transmitter. Further advantages are better safety (due to increased distance to load), better data transmission reiliability (frequency hopping), ergonomic design, and commissioning that is quick and simple.
