The Cat 317 series hydraulic excavator undercarriage provides incredible stability. Precision robotic welding helps ensure quality welds that increase rigidity, reduce stresses and enhance durability for the chassis and track roller frames. Featuring a modified X-shaped chassis design, Cat undercarriage components are purposely oversized to meet heavy-duty demands over a long life. All track links are sealed, while track rollers, carrier rollers and idlers are also sealed and lubricated for excellent service life. Smoother auto shifting two-speed travel motors offer top travel speeds and plenty of pull on slopes or turns. Long (L) undercarriage maximizes stability and lifting capacity. Long and Narrow (LN) undercarriage is also available to ease transportability of the machine. With proper undercarriage maintenance, a Cat 317 series hydraulic excavator can outperform the competition.
