In a significant cross-border collaboration, a delegation of heavy equipment clients from Indonesia recently visited the VM® Crawler Crane Manufacturing Factory to assess our production capabilities and finalize a bulk order for Hitachi Sumitomo SCX550 crane undercarriage parts.
Hitachi Sumitomo SCX550 is one of the best 55-ton class crawler cranes, which is commonly employed in various construction sites in Indonesia, ranging from oil refinery industries to heavy machinery workshops, amongst many others. Unfortunately, procurement of quality parts that match up to OEM standards for the Hitachi Sumitomo SCX550 has always been an uphill task for local fleet owners.
During their visit to our factory premises, the customers thoroughly inspected the production line of VM in relation to the manufacture of the following parts:
Hitachi Sumitomo SCX550 Track Rollers
Carrier Rollers
Hitachi Sumitomo SCX550 Sprockets
Idlers
Hitachi Sumitomo SCX550 Track Shoes
After reviewing material certification certificates, hardness test reports (covering a range of HRC 52–58), and welding integrity test results, the clients made an immediate decision to place an order for a complete set of Hitachi Sumitomo SCX550 undercarriage parts.


Precise Fitment — Designed for direct installation and replacement on Hitachi Sumitomo SCX550 equipment, with absolutely no modifications required.
Deep Hardened Layer — Effectively maximizes resistance to premature wear on track rollers and sprockets.
Sealing Reliability — Utilizes floating oil seals that have undergone rigorous testing to withstand contamination and corrosion in tropical, high-humidity environments—such as those found in Indonesia—ensuring long-lasting and stable sealing performance.
