Shengjian Fanrong manufactures Bridge Crane Counterweights using HT200 gray cast iron and V-process vacuum casting technology for overhead crane manufacturers, industrial lifting equipment suppliers, and heavy machinery companies.
Founded in 2008, Shengjian Fanrong specializes in customized casting and mechanical component manufacturing. Our counterweights are produced according to customer drawings, samples, and technical specifications, covering casting, machining, surface treatment, inspection, and delivery.
With a 60,000㎡ manufacturing base and an annual production capacity of 80,000 tons of precision mechanical components, we support OEM projects requiring stable weight performance, consistent dimensions, and customized industrial casting capability.
Shengjian Fanrong produces HT200 gray cast iron Bridge Crane Counterweights for overhead cranes, bridge cranes, gantry cranes, and other heavy lifting systems.
In industrial crane applications, counterweights are used to maintain proper mechanical balance according to equipment structure and operating requirements.
Different cranes require different counterweight designs. Factors such as crane type, lifting capacity, installation position, connection method, and working environment influence the final component design.
Before production, our engineering team reviews customer drawings, samples, and technical requirements to confirm:
Shengjian Fanrong uses HT200 gray cast iron for customized bridge crane counterweight manufacturing.
HT200 is widely used for industrial cast components because it provides stable casting performance, suitable mechanical strength, and consistent material characteristics.
Key characteristics include:
Supports the production of heavy components where accurate weight distribution is required.
Suitable for producing customized industrial castings with complex shapes and large dimensions.
The graphite structure of gray cast iron provides natural vibration damping characteristics.
Allows secondary machining processes when required by installation specifications.
Shengjian Fanrong applies V-process vacuum casting technology for HT200 gray cast iron components.
The V-process casting method uses vacuum pressure and plastic film molding technology to maintain mold stability during casting production.
The manufacturing process includes:
Patterns are prepared according to approved drawings or existing samples.
A plastic film is applied over the pattern surface.
Vacuum pressure forms a stable sand mold without traditional chemical binders.
Molten iron is poured according to controlled production procedures.
After solidification, castings are removed for cleaning and inspection.
Additional machining and surface treatment are completed according to requirements.
Advantages of V-process casting:
| Item | Capability |
|---|---|
| Material | HT200 Gray Cast Iron |
| Casting Method | V-Process Vacuum Casting |
| Production Type | OEM Customized Production |
| Manufacturing Basis | Customer Drawing / Sample |
| Machining | Available |
| Surface Treatment | Shot Blasting / Coating |
| Inspection | Dimension / Weight / Appearance Inspection |
| Application | Overhead Crane / Bridge Crane / Gantry Crane |
Bridge crane counterweights require stable weight distribution, consistent dimensions, and reliable structural performance during long-term operation.
Compared with conventional molding methods, V-process casting provides advantages for customized industrial castings:
Vacuum molding helps maintain mold integrity during pouring, supporting consistent casting dimensions.
The plastic film molding process helps reduce surface defects and improves casting appearance.
V-process technology is suitable for producing large gray cast iron components with customized shapes.
Improved mold quality can reduce additional surface cleaning work after casting.
Shengjian Fanrong has supplied customized cast iron counterweight components for industrial lifting equipment manufacturers requiring stable weight performance, accurate dimensions, and reliable casting quality.
