建設機械用電気操作レバー。 In addition to the conventional spring, a feeling spring is added below the rod that is operated by an electric control lever for construction machinery, so that the operating force changes discontinuously at a specific position of the rod, and the discontinuity point and The starting point of the actuator is made to coincide with the starting point of the actuator, so that the operator can sense the starting point of the actuator's movement by changing the operating force.
Electric control lever for construction machinery.
