Caterpillar expands Tilt Rotate System (TRS)

Design benefits
The compact design of the TRS4, TRS6 and TRS8 allows the mini excavator to maintain high digging forces. A reinforced TRS gearbox with a specially designed bearing ring distributes working forces to reduce stress on the TRS and the host machine. A no-maintenance lubrication system for the rotation system effectively distributes heat. The high-torque rotation system quickly positions work tools, and an integral self-locking mechanism enables digging at any angle required. Single/minimal grease points for TRS models delivers quick, efficient greasing of all joints requiring lubrication.

Integrated load-hold valves for the double-acting tilt cylinder maintains holding pressures and prevents cylinder movement under load. Cylinder design features hardened pistons and maintenance-free bearings, and its scratch-resistant, rust-proof surfaces require no maintenance.

An integrated, dealer-installed field control kit, which includes specially designed joysticks, suits all boom-and-stick combinations and provides intuitive control of the TRS and integral grapple. The TRS monitor informs the operator of the attachment’s position, and an engagement/disengagement sensor assures that work tools are secured via a safety locking mechanism with indicator. Activated by a joystick button, all TRS models offer a bucket-shake feature to facilitate even spreading of materials.
