The Trencor 60 Series features Cat®-type undercarriages for reduced maintenance, and fast 2-speed drive motors for optimum travel speeds. The digging booms can be sectionalized for easy dimension changes, and many of the models can accommodate either a rocksaw or Roadminer® attachment.

The 665HD through 1860HD models have an exclusive mechanical powertrain. This technologically advanced approach has proven superior to the less powerful hydrostatic or competitive mechanical systems for hard rock applications. The Trencor Mechanical Powertrain® features a multi-speed powershift transmission with torque converter, heavy-duty differential, and fully enclosed chain final drive, all of which combine for a multiplication of torque output. With this arrangement, higher torque is available at lower chain speeds. Low chain speed operation allows better penetration, reducing tooth cost and machine wear.

There are two types of power trains currently in use with chain trenchers. In recent years, the hydrostatic drive has been perhaps the most common method of delivering power to moving parts. But the hydrostatic drive does have some short comings, including power lost due to heat, inherent inefficiencies with hydraulic pumps and motors, system complexity, high maintenance cost, and a short band of digging speeds. The mechanical drive, on the other hand, offers a range of positive benefits.

Increased torque- More than 90% of the engine horsepower can be delivered to the cutting tool.

Increased productivity- The cutting tool tends to break out more and larger pieces of material thanks to the slow-moving digging tooth and the force delivered by the high torque.

Broader range of chain speeds- There is a transmission in the Trencor mechanical drive that lets the operator choose a digging speed that matches the digging conditions.

Reduced fuel cost- The additional horsepower delivered by the system gets more work done in the same amount of time.

Ease of repair- The system is much less complex. In most cases, a simple visual inspection can lead to the diagnosis of a problem.

Lower repair cost- The components of the system are mostly off-the-shelf parts that can be replaced at a relatively low cost. There are also fewer moving parts to wear out or break.

Long machine life- A mechanical drive system can better absorb the pounding shocks of trenching operations. The average life of a Trencor mechanical power train trencher is quite long-which permits amortization of the machine over a longer period of time. More than 90% of the engine horsepower can be delivered to the cutting tool.

Trencor T1060 Mechanical Drive Chain Trencher The Trencor T1060 offers powerful trenching ability in a compact package. The first of two new Trencor models to be released this summer, the T1060 features a newly styled sloped hood, extraordinary performance, and the latest technology throughout its innovative design. The C-9 Tier 3 Stage IIIA Caterpillar 350-horsepower engine meets all emission standards and transmits power to the digging chain through a proven 3-speed Allison transmission, which allows maximum torque in each trenching speed. Like all Trencor models, the T1060 boasts the rugged frame construction for which Trencor is known—its unibody tractor frame is stronger than tube and bolt-on sheet metal designs. Extra-long, welded, heavy-duty undercarriage sits within an 8-foot, 5-inch overall width to work in tight job conditions. Narrow profile allows transportation without oversize permits.

Trencor Roadminers

While planers and profilers can only cut 8 to 15 inches deep, the Trencor Roadminer® can cut up to 16 feet wide and 6 feet deep in a single pass.
A Roadminer® eliminates blasting in most cases. The cut is clean, even, and ready for further construction.

Uses include certain quarry operations, road construction, building foundation work, and mass rock removal. A Roadminer® cuts wider than its tracks, therefore making multiple passes possible, which produces a vertical wall.
