Shengjian Fanrong manufactures hydraulic excavator counterweights for excavator manufacturers, construction machinery suppliers, and replacement parts distributors requiring customized balance components.
A counterweight is not simply a heavy casting added to an excavator. Its position, weight distribution, mounting structure, and overall dimensions directly affect machine balance during digging, lifting, and swing operations.
Shengjian Fanrong produces cast iron, pig iron, and ductile iron excavator counterweights according to customer drawings, existing samples, excavator models, and installation requirements.
From engineering review and mold development to casting production, surface finishing, inspection, and export packaging, each counterweight project follows a controlled manufacturing process designed around equipment compatibility.
A hydraulic excavator counterweight is installed on the rear section of the excavator upper structure to help maintain balance between the working attachment and machine body.
During operation, excavators experience constantly changing forces caused by:
The counterweight must provide sufficient balancing force while matching the original machine structure.
For OEM customers, the key requirements are:
Different excavator models have different rear structures, mounting systems, and operating conditions.
Before manufacturing, Shengjian Fanrong engineers review:
The purpose is not simply producing a heavier component.
The objective is manufacturing a counterweight that matches the equipment design and maintains proper weight distribution during operation.
Shengjian Fanrong supports OEM production for:
Customers can provide:
For projects without original drawings, engineers can evaluate available samples and equipment information to determine manufacturing feasibility.
Different applications require different material characteristics.
Suitable for:
Advantages:
