Title:
Construction machinery provided with a turn controller and this
Document Type and Number:
Japanese Patent JP6115121
Kind Code:
B2
Abstract:
The invention provides a rotation control device (5) capable of reducing a loss of a power of a hydraulic pump (15) in a backward direction operation and also provides a construction machine (1) including the same. The controller (24) controls a capacity of the hydraulic pump (15) such that, in a forward direction operation in which an operating direction detected by the operation sensor (18A, 18B) and a rotating direction detected by a rotation sensor (23) coincide with each other, the capacity of the hydraulic pump (15) is increased in accordance with an increase in the operation amount detected by an operation sensor (18A, 18B), on the other hand, restricts the capacity of the hydraulic pump (15) more in a backward direction operation, in which the operating direction detected by the operation sensor (18A, 18B) and the rotating direction detected by the rotation sensor (23) are reverse to each other, than in the forward direction operation.
