Counterweights for Construction, Sanitation & Agricultural Machinery
Precision Cast Iron from Zunhua Shengjian Fanrong Machinery Parts Co., Ltd.
Zunhua Shengjian Fanrong Machinery Parts Co., Ltd. is a manufacturer and exporter of cast-iron counterweights located in Zunhua, Hebei, China. Since 2017, we have specialized in the design, casting, and finishing of counterweights for excavators, wheel loaders, sweepers, harvesters, and industrial forklifts. Our export business serves buyers in Southeast Asia, Europe, the Middle East, and Africa, with standard parts held in stock and custom parts produced to order.
What a Counterweight Does, and Why Quality Matters
A counterweight balances the machine, improving stability, reducing operator fatigue, and extending component life. In construction, sanitation, and agricultural equipment, an off-tolerance or poorly cast weight can affect lift performance and safety. That is why our production is standardized end to end:
Raw material selection and chemistry control;
Precision casting to target density;
Finish grinding for dimensional accuracy;
Dimensional and density inspection before packing;
Anti-corrosion surface treatment for outdoor service.
Rather than relying on general statements, we publish measurable parameters on every product sheet:
| Parameter | Typical value | Your part |
| Weight tolerance | ±【数值，如 ±1.5】 % | per drawing |
| Key dimension tolerance | ±【数值，如 ±2】 mm | per drawing |
| Density | 【数值，如 7.2】 g/cm³ | per material |
| Surface treatment | 【如 anti-rust paint / zinc】 | optional |
Standard counterweights: stocked in common models for excavators, loaders, and forklifts; ready for fast dispatch.
Custom counterweights: produced from your drawing, with a prototype available before mass production. Custom options include shape, weight, mounting holes, and surface finish.
We produce both single-piece and batch orders, from small trial lots to large procurement for machinery manufacturers and distributors.
