Abstract

A one-handed joystick for cranes allows an operator to make all necessary motions with a single hand and arm for manipulating various components of a crane. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring, an industrial joystick base, a rocker switch and at least two push button switches. Motions of the rotatable cylinder bar, the rotatable ring, the industrial base and the rocker switch are used to raise and lower the auxiliary hoist; raise and lower the telescopic boom for luffing a hoist; raise and lower the main hoist; slew the boom base in a clockwise or counterclockwise direction; and extend or retract the telescoping boom. The speed of main and auxiliary hosts may be changed with the two push button switches. A Deadman's switch may be installed on a back side of the rotatable cylinder bar.
