Advantages of the VM® Hitachi Lower Track Roller for Crane:
1) VM® PD90 bottom rollers are forged from premium alloy steel for superior strength. The advanced heat treatment ensures a deep, uniform hardness that extends service life. Every VM® bottom roller and idler is 100% tested for dimensional accuracy and rotational smoothness, ensuring it matches the performance of our top rollers and sprockets.
2) High-quality materials with high tensile strength (≥800 MPa) support heavy loads of crawler cranes, ensuring stable operation. Pre-lubricated design reduces maintenance frequency, saving time and labor costs for customers
Customer Feedback of VM® Hitachi PD90 Undercarriage Parts:
The VM® track shoe, bottom roller, top roller, sprocket, and idler we installed on our Hitachi have outlasted the previous part by over 30%. The seal is excellent, and the build quality is solid. We will be sourcing our other crane parts from VM® next time.” – Carlos G., Maintenance Manager.
