摘要： PROBLEM TO BE SOLVED: To surely hold a turning body in a stopping state, to smoothly perform the turning deceleration/stopping and acceleration action, to prevent an energy loss for stopping and holding; and to use an existing mechanical brake as it is.
SOLUTION: A section for stopping-holding the turning body only by the mechanical brake 27, a section for holding the turning body only by position holding control and a section for simultaneously operating both are set in a neutral range of a preset operation lever 28a. At turning deceleration time, when a turning speed becomes a preset position holding control starting speed or less, the position holding control is started, and when a state of being not more than a brake operating speed continues for a specific time, the mechanical brake 27 is operated.
