Title: Lift controller for ground operating machine
Inventor: KATO HIRONOBU
IPC: A01B63/11
Filed: 1988-09-13
Abstract: PURPOSE:To prevent accidental movement by locking the machine so as not to be driven to rise upward, even when the switch is operated upward, once the actual height is detected higher than the upper limit position. CONSTITUTION:At start, the actual height of the machine by the lift sensor 15 is compared with the lifting limit of the setter 20 in the computing unit 21 and judged in the unit 27 whether the lifting movement of the machine should be locked or not, and only in the case when locking is needed, the lifting movement of the machine is locked. This locked state is automatically unlocked by detecting the relationship between the actual height of the machine by the operation of the switch 18 and the lifting limit position, thus it is not troublesome for the operator. Thus, wrong operation can be detected and locking can be done, when needed, and there is no troubles that the lock must be released, every time when the engine is started.
