Bobcat has introduced a new solid-mount and optional Roller Suspension system undercarriages for select compact track loaders, including the T550, T590, T630, T650, T740, T750 and T770.
Dual-flange front idlers now ride on the rubber track’s roller way. According to Bobcat, these new front idlers, along with wider rollers, help reduce vibration, which improves operator comfort while reducing track wear on the inside of the track. Single-flange idlers are still found on the rear of the machine to help minimize de-tracking.
The optional Roller Suspension system has also been changed to optimize ride and operational characteristics. It also incorporates the dual flange front idlers, wider rollers, along with mono-leaf springs, for smoother action. The front idlers have been relocated to enhance machine operation.
A horizontally mounted tension cylinder is designed to open up more room between the carriage and track for easier cleanout. Bobcat says the undercarriage is sloped on both sides to shed material, such as sand, dirt, mud and debris, better than the previous design. Additionally, raised cutouts between the rollers allow for easier cleaning.
The change also means increased fuel capacity. Depending on the model, Bobcat says operators will see an increase in fuel capacity by up to 45 percent. Actual volume and operational time will vary by machine model.
Ground clearance at the center of the undercarriage has been increased by up to 29%, which should allow operators to travel through mud, sand and other soft soil conditions more easily. Clearance at the rear of the machine has also been increased. This allows machines to travel over curbs and other obstacles with less chance of catching on them.
Finally, narrow and wide tracks for compact track loaders are interchangeable at a Bobcat dealership.
