Caterpillar’s new Dual-Lock Tilt pin-grabber-type hydraulic coupler gives 5- and 8-ton mini hydraulic excavators the ability to rotate work tools through a 180-degree arc. New rotary actuator provides up to 35% more holding torque, reduces overall weight by 15%, and simplifies hydraulic-line routing, compared with after-market actuators. Helically cut and hardened gears used in the actuator ensure positive action and long-term durability. Work tools can be changed from inside the cab, with a primary locking system that uses a wedge plate positioned via a hydraulic cylinder with an integrated check valve. The secondary lock is spring-applied and hydraulically released.
