TRUCK MIXER AND DRUM EMERGENCY DRIVE TOOL OF TRUCK MIXER

摘要

PROBLEM TO BE SOLVED: To provide a truck mixer and a drum emergency drive tool that can rotationally drive a mixer drum when an engine or the like fails.SOLUTION: A drum emergency drive tool 20 is used for a truck mixer 100 that comprises a fluid pressure motor rotating by engine power and a decelerator 7 having an inner peripheral spline 76A (normally-used input part) with which the fluid pressure motor is coupled and decelerating the rotation of the normally-used input part (inner peripheral spline 76A) to transmit the same to a mixer drum 2. The drum emergency drive tool comprises a relay shaft 25 coupled with the inner peripheral spline 76A with the fluid pressure motor 6 removed from the decelerator 7, where the relay shaft 25 has an emergency input part 27 with which a tool 30 capable of rotational actuation is coupled.SELECTED DRAWING: Figure 3A
