Do excavators have wheels or tracks?
Track excavators are best when you have a long-term project and the excavator can stay on-site for a while. Wheel excavators move well between job sites and can be driven on the road, making them best for short-term, fast-paced projects.
YYR offers a complete range with its rollers for both excavators and bulldozers from 0.8 to 100 tons. We produce all bottom rollers and top rollers based on OEM specifiions. The production is finished on high-tech CNC machinery with precision tools, high-grade seals and bronze bushings (bimetal).
DIFFERENT TYPES OF BOTTOM ROLLERS
Bottom rollers for excavators have a thick axle for bearing the machine’s weight These bottom rollers have a smaller running surface diameter, because the machines do not need to do much mobile work.
