XXL CRAWLER SYSTEM

Size matters when it comes to carrying the immense weight of the P&H 4100XPC machine. With its superior performance the XXL Series undercarriage is sure to become the norm. JRK has taken the original design and improved on it. We implemented our tried and true internal structure optimization and opened the roll path by approximately 20% giving us enhanced load dispersion. The forged XXL series lower rollers are enlarged dimensionally both at the thrust face and rolling surface. Our track shoe drive lugs and tumbler drive lugs have been enhanced to provide exceptional engagement and greater side frame clearance throughout life. Optional widened front idlers and guide rails complete the system. Altogether the XXL series 4100XPC crawler system is certain to out perform the original equipment design.
