Frame
The main frame consists of a weldment or casting which hangs the front alignment
assembly and rear tension link. 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. 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.
