TRANSMISSION GEAR FOR WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To organically combine a technique for tow-controlling so as to be unable to travel during braking for parking as an electric control type transmission is adopted. SOLUTION: A driving operation type transmission He equipped with a hydraulic cylinder for operating a main speed change mechanism and the first subspeed change mechanism on a speed change command sent from a main speed change lever 26 is composed, and a departure locking means F is provided for controlling so that a speed change mechanism may be turned into a transmitting state so as to transmit power to a wheel only in the case where the main speed change lever 26 is changed over to a speed change position as a parking brake lever 23 is set at a releasing position from a state where a parking brake is in a nonfunction state, and the main speed change lever 26 is at a neutral position is provided.
