The invention belongs to the technical field of cranes, and particularly relates to a multi-control electric control handle and a crane. Through the arrangement of the sliding control piece, linear displacement proportion signal output can be achieved by pushing the sliding key, and when the sliding key is loosened, the sliding key and the connecting block can automatically recover to the middle position under the action of the reset piece. One or more sets of sliding control pieces are additionally arranged on the basis of an original double-shaft movement self-resetting handle, two sets of angular displacement proportion signals in the front-back direction and the left-right direction can be output by shaking a grip, and a third set of linear displacement proportion signals can be output by pushing up or down a sliding key on a panel. The electric control handle can output three groups or more groups of electric proportional signals, so that more proportional valves of the crane can be conveniently controlled.
本发明属于起重机技术领域,尤其一种多控制电控手柄及起重机。通过滑移控制件的设置,推动滑动键可以实现线位移比例信号输出,松开滑动键,在复位件作用下滑动键和连接块会自动恢复到中位。在原有双轴运动自复位手柄的基础上增设一组或多组的滑移控制件,摇动握把可以输出前后方向、左右方向的两组角位移的比例信号,上推或下推面板上的滑动键,可输出第三组线位移比例信号。本发明的电控手柄能够输出三组或者更多组的电比例信号,方便起重机更多比例阀的控制。
