Undercarriage Engineered for performance Suspended Undercarriage Design Absorbs impact loads, to reduce the shock loads transferred to the undercarriage, by up to 50%. Bogie Suspension Bogie suspension conforms closely to the ground providing up to 15 percent more ground contact, especially in uneven terrain. Higher traction means less slippage, better balance, and a smoother ride. Integrated Carrier Roller Mount The carrier roller mount is cast into the track roller frame making it easier to add the optional carrier roller in the field, if conditions require it. Rollers and Idlers Feature...
