REVOLVING WORK VEHICLE PROVIDED WITH ELEVATABLE OPERATOR CAB

摘要

PROBLEM TO BE SOLVED: To provide a revolving work vehicle provided with an elevatable operator cab capable of solving a problem that the operator cab installed at a revolving machine body so as to freely elevate is largely swung by reaction when the revolving machine body starts to revolve and stops at a "moving up position" without deteriorating revolving manipulability and also without deteriorating the balance of the revolving work vehicle.

SOLUTION: This revolving work vehicle includes: the operator cab installed at the revolving machine body to be moved between the "moving up position" and "a moving down position" so as to freely elevate; a controller controlling the operation of a revolving actuator revolving the revolving machine body based on an output from the operating unit of the operator cab; and an adjusting means adjusting the output from the operating unit when the operator cab is in the "moving up position" to decelerate the operating speed of the controller in comparison with that in the "moving down position".
