Caterpillar says that the addition of the new TRS23 Tiltrotator System (TRS), from its Work Tools division delivers a full portfolio of TRS configurations for its wheeled and crawler excavators weighing 23-30tonnes. The TRS23 has an integrated control system that boosts carrier versatility and attachment control. The unit can rotate 360° in either direction and tilt up to 40° left and right. This allows the carrier to reach more work areas from a single position and to manoeuvre around obstacles.
The TRS23 is available with pin-on and coupler interfaces for handling a range of grading and trenching buckets (with CW-, CWs-, or S-coupler tops and bottoms), and an available swivel can operate such work tools as compactors and grapples. An optional grapple module allows picking and placing material without changing work tools.
The tool has the firm’s SecureLock device, which is said to ensures a positive tiltrotator connection to the carrier using both hydraulic and mechanical locking. It also has a sensor-based confirmation system with audible signals and visual in-cab indicators. Integral load holding valves are designed to maintain cylinder stability and to secure loads, even if lines are cut.
Long-term reliability and durability for the TRS23 result from the heavy-duty bolted joint that secures the housing, rotator, and coupler as a unit. The worm gear drive is designed with wide bearing surfaces to distribute forces in all directions. In addition, the gear drive is submersed in oil to ensure positive lubrication. Pins, shafts, and bushings feature heavy-duty construction, and the hydraulic rotator motor is protected inside the cast rotator housing.
