The Bobcat suspended undercarriage is a feature found in certain Bobcat machines, particularly their skid steers and compact track loaders. This technology is designed to enhance the machine’s performance, improve operator comfort, and extend the life of the machine when working in challenging terrains. In this article, we will take a detailed look at the design and benefits of the Bobcat suspended undercarriage, common issues, and best practices for maintenance to ensure optimal performance.
What is a Suspended Undercarriage?
A suspended undercarriage is a system where the undercarriage of a machine—usually the tracks or wheels—are mounted on independent suspension components. Unlike traditional undercarriages that are rigid, a suspended undercarriage allows for a certain level of movement, which provides enhanced shock absorption and greater flexibility in rough or uneven terrain. This results in smoother operation and better load handling, especially when working over rocky, muddy, or rugged surfaces.
Bobcat’s suspended undercarriage is especially prevalent in their compact track loaders (CTLs), such as the Bobcat T650 or Bobcat T870 models, where the undercarriage helps to maintain traction and stability, even in conditions that would cause other machines to struggle. The suspension system in these machines helps absorb shock and reduces the impact on the overall frame of the machine, making it more durable and reducing the risk of operator fatigue.
