New solid-mount and optional Roller Suspension system undercarriages are available for select Bobcat 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. These new front idlers, along with wider rollers, help reduce vibration and in turn reduce 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 opens up more room between the carriage and track for easier cleanout. The undercarriage is sloped on both sides to shed material, such as sand, dirt, mud, and debris. Additionally, a raised cutout between the rollers allows for easier cleaning.
Depending on the model, 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 improved by up to 29 percent, helping operators travel through mud, sand and other soft soil conditions more easily.
Clearance at the rear of the machine has been increased. This allows machines to travel over curbs and other obstacles with less chance of catching on them.
Narrow and wide tracks for compact track loaders are interchangeable at a Bobcat dealership.
