Crawler Excavator Counterweights

Designed for Stable Performance in Heavy Excavator Operations

The rear counterweight is an important balancing component of crawler excavators. It works together with the machine structure to provide additional weight at the rear section, helping maintain proper balance during working cycles.

The Crawler Excavator Counterweights are developed for applications where equipment requires:

· Improved balance during excavation operations.

· Suitable weight distribution during rotation.

· Reliable performance under continuous workload.

· Accurate matching with original installation structures.

For different excavator models, the counterweight shape, weight, and mounting structure may vary. Shengjian Fanrong supports customized manufacturing based on actual equipment requirements.

Material Selection and Structural Design

HT200 Gray Cast Iron for Heavy Machinery Applications

Shengjian Fanrong mainly uses HT200 gray cast iron for excavator counterweight manufacturing.

This material provides:

· High density for effective weight balancing.

· Suitable wear resistance for industrial environments.

· Good shock absorption characteristics.

· Stable mechanical performance during long-term operation.

The material selection is based on the functional requirements of heavy machinery counterweight applications.

Engineering-Based Structure Design

Crawler excavator counterweights generally feature a curved “bread-shaped” structure.

The main structural characteristics include:

· Curved outer surfaces matching equipment design.

· Flat bottom mounting surface.

· Embedded screw holes inside the structure.

· Controlled positioning accuracy for installation.

These design elements help ensure proper connection between the counterweight and excavator body.
