Frame
The main frame consists of a weldment which hangs the front and rear link arms. The
front alignment yoke and rear tension link are cast members, allowing for close tolerance
machining and structural rigidity.
Axles
Front and rear axles are machined from the yoke castings, allowing for dimensional
stability and few moving parts. They feature oil bath hubs mounted on tapered bearings
and mechanical seals for extreme working conditions. Each hub has its own oil reservoir
with access port for maintenance and checking oil levels.
Idlers and Midrollers
The idlers have the function of guiding the rubber track by acting on the lateral surfaces of
the guide lugs. Inner sides of idlers are subject to wear, but can be rotated to extend life.
The midrollers distribute the majority of the machine weight to the ground. They are
mounted on pivoting arms connected to the frame reducing vibration and shock loads.
Tensioning system
The tensioning system is located between the 2 rear idlers. The tension force is provided
by a mechanical spring mechanism. Track tension is provided by the spring and does not
need adjustment during operation and changing field conditions. Provisions are made to
compress the spring allowing for removal of idlers and track assemblies during
maintenance and servicing.
Rubber track
The rubber tracks are manufactured with high quality rubber and high strength steel
cabling inside for superior durability and reliability. The tread layout ensures good
flotation, excellent life, and self-cleaning characteristics.
