SWING LOCK DEVICE FOR CONSTRUCTION EQUIPMENT |
摘要 |
A swing locking device for a construction machine is disclosed, which enables an operator in a cabin to confirm the locking/unlocking state of the locking device that locks a swing device or to operate the locking device. The swing lock device for a construction machine includes a lower driving structure, an upper swing structure mounted to swing on the lower driving structure by a swing device, a ring gear for locking the swing device formed on an outer surface of a ring gear for the swing device that forms the swing device, an actuator correspondingly formed to be tooth-engaged with the ring gear for locking the swing device to engage or disengage a locking gear fixed to a cylinder rod, an alignment setting confirmation sensor detecting whether setting is completed by the tooth-engagement between the ring gear for locking the swing device and the locking gear through driving of the actuator, and a swing lock/unlock detection sensor detecting a swing lock state in which the locking gear is engaged with the ring gear for locking the swing device or a swing unlock state in which the locking gear is disengaged from the ring gear (10) for locking the swing device through the driving of the actuator. |
