Two Types of Suspension Available on Terex Compact Track Loader Undercarriages

Construction Equipment Guide

Terex compact track loader undercarriages feature two types of suspension: single level or dual level. On single level suspended undercarriages, the entire undercarriage is suspended from the chassis of the machine by torsion axles. These torsion axles are independent, so there are four suspension points connecting the chassis to the undercarriage. This creates a smooth ride, and takes away much of the vibration and shock associated with running over rocks, curbs, and other rough terrain, according to the manufacturer.

On dual level suspended undercarriages the same suspension system is used as on the single level, but a second level is added. This second level allows the bogie wheels of the machine to flex as well, creating enhanced ride comfort and traction.

All Terex compact track loaders use undercarriage technology with suspension that maximizes traction and flotation while giving operators the most comfortable ride possible.

Terex Posi-Track undercarriage technology relies on more than 25 years of technology that provides performance and durability by using modern track technology and components used and proven in much larger equipment, such as metal faced seals.

Terex offers three different track options for its undercarriages. The standard track on all Terex CTLs is the general purpose track. The general purpose track features a moderate tread pattern that the company recommends for use in the widest range of applications, from wet, soft ground to working on soft, delicate landscaping, to operations on pavement or asphalt. These tracks are made of a special rubber compound that is tough, durable and relatively lightweight when compared to steel-imbed tracks used on other machines. Tracks with less weight give Terex machines the ability to travel faster and offer better performance than other commonly-used tracks, according to the manufacturer.

Terex also offers a special turf track on select models. Turf tracks are ideal for landscapers and anybody working over fragile or improved surfaces. They feature a special smooth tread that allows Terex CTLs to maneuver on virtually any surface with barely a trace. Scuffing and rutting is practically eliminated, even when used in sharp turns. Terex recommends its turf tracks for applications where the surface needs special protection and the conditions are generally dry. Many landscape construction contractors use Terex turf tracks throughout much of their work season, whether on dirt or turf.

Users of Terex mid-sized CTLs have the option of outfitting their machine with a specialized track option that improves machine performance in the most extreme ground conditions. These extreme terrain tracks are wider and feature more aggressive treads to give users added traction for working through the most difficult conditions with better results than ever before. The new extreme terrain tracks give machine users yet another option for even higher performance in difficult ground conditions.

Terex extreme terrain tracks measure 16.5 in. (42 cm) wide, spreading the machine weight even more than standard tracks that measure 15 in. (38 cm) wide. This lowers the ground pressure of machines equipped with extreme terrain tracks by 10 percent. Lower ground pressure translates into higher flotation for better operation in soft conditions.

These special tracks also have a noticeably deeper tread pattern that gives them more traction in soft, wet conditions and wider spacing between tread lugs makes them self-cleaning. As a result, they remain free of packed material and the treads are more effective, even in sticky, cohesive materials. Because these tracks are designed for use in special, extreme and soft ground conditions, Terex does not recommend them for use on normal, dry or firm ground conditions.
