Shengjian Fanrong manufactures OEM wheeled excavator counterweights for construction machinery manufacturers, aftermarket suppliers, and equipment distributors. The company develops cast iron, ductile iron, and pig iron counterweights based on excavator models, existing samples, and technical drawings, supporting single-piece casting from 1 to 15 tons.
From reverse engineering and mold development to casting, finishing, inspection, and export packaging, Shengjian Fanrong provides complete manufacturing support for replacement and OEM counterweight projects.
Wheeled excavators operate in different conditions from crawler excavators. They are frequently transported between working locations and commonly perform digging, lifting, and swing operations on uneven surfaces.
The counterweight must match the excavator structure and operating conditions to maintain proper balance during machine movement.
During engineering review, Shengjian Fanrong considers:
A properly matched counterweight helps maintain suitable weight distribution between the working attachment and the machine body.
Many replacement counterweight projects begin with an existing component rather than original CAD drawings.
For discontinued equipment or unavailable spare parts, Shengjian Fanrong supports development based on:
The engineering process includes:
This approach allows customers to reproduce counterweight components when original supply channels are unavailable.
Shengjian Fanrong manufactures wheeled excavator counterweights using materials selected according to equipment requirements and application conditions.

The company operates under ISO 9001, ISO 14001, and ISO 45001 management systems.
Shengjian Fanrong does not only manufacture according to finished drawings.
For replacement projects, engineers can evaluate existing components and develop production solutions based on available information.
Counterweight projects are managed through:
Engineering review → Mold development → Casting production → Finishing → Inspection → Shipment
This reduces communication between multiple suppliers and simplifies OEM cooperation.
With single-piece casting capability from 1 to 15 tons, Shengjian Fanrong supports medium and heavy construction machinery applications requiring customized counterweight components.
