Cat’s TRS23 Tiltrotator System for Wheel and Track Excavator

Published: 19/8, 2019

The TRS23, featuring a fully integrated control system that enhances carrier versatility and attachment control, rotates 360° in either direction and tilts up to 40° left and right, allowing the machine to reach more work areas from a single position, and to manoeuvre around obstacles. The new 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 which can operate such work tools as compactors and grapples. An optional grapple module allows picking and placing material without changing work tools.

Cat’s “SecureLock” ensures a positive tiltrotator connection to the carrier by using both hydraulic and mechanical locking mechanisms, as well as 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. Heavy-duty bolted joints secure the housing, rotator, and coupler as a unit. The worm gear drive is designed with wide bearing surfaces that distribute excavation forces in all directions. In addition, the gear drive is submersed in oil to ensure positive lubrication in all operating conditions. Pins, shafts, and bushings feature heavy-duty construction and the hydraulic rotator motor is protected inside the cast rotator housing.

Other features include bucket pulse, designed to automatically spread material evenly and quickly. Optional RPS sensors track the position of the tiltrotator, showing data on the in cab monitor, as well as sharing information with grade control systems. For precise attachment control, the TRS23 allows “home” positions to be stored for returning the tiltrotator (with the press of a button) to a user defined position. The Innovative Lubrication System (ILS) simplifies daily maintenance, allowing the tiltrotator to be greased from one location or connected to the machine’s automatic lubrication system.
