Swamp shoes are critical attachments designed for excavators operating on soft, swampy, or marshy terrain. For a 20-ton excavator, such as the Hitachi EX200-5 or comparable models, swamp shoes enable the machine to distribute weight more effectively over soft ground, preventing sinking and improving stability. These specialized track shoes are engineered to enhance flotation, durability, and traction in challenging environments.
Material and Structural Design
Swamp shoes for 20-ton excavators are usually fabricated from high-strength alloy steels such as China WISCO’s HG785D steel, noted for its exceptional yield strength (around 685 MPa) and tensile strength (approximately 785 MPa). This material also features impact energy resistance above 47 joules at -20°C, ensuring resilience even in cold and harsh weather.
The track shoe cleats are integrated with the chassis framework, which benefits from reinforced welds to prevent deformation. Heat treatment processes, including quenching and tempering, enhance wear resistance and toughness, enabling these shoes to withstand high-abrasion environments common in swampy areas.
Key Specifications
Swamp shoes substantially increase ground contact surface area, reducing ground pressure and enabling excavators to float on soft soil rather than sink. This effect is critical in wetland restoration, pipeline work, and other operations where ground disturbance must be minimized.
The reinforced box design track shoes also improve traction during operation, aiding in mobility when "paddling" in water or mud. High wear resistance reduces the frequency of part replacements, which decreases downtime and improves project efficiency.
Maintenance Recommendations
To sustain the longevity of swamp shoes:
Projects working in wetland environments have noted that using high-strength swamp shoes allows 20-ton excavators to maintain productivity where conventional tracks would fail due to sinking or loss of traction. One operator shared that upgrading to reinforced swamp shoes reduced traditional grounding delays by over 40% on a large logging site in marshlands.
Manufacturers continually innovate with materials and structure, seeking to strike the optimal balance of strength, flexibility, and weight. Their advancements contribute to safer, more reliable excavator operations in sensitive ecosystems.
Summary
Swamp shoes designed for 20-ton excavators are specialized heavy-duty track shoe assemblies made from high-strength steel and wear-resistant materials. They provide essential flotation, traction, and durability required for swamp and soft terrain operations. Proper maintenance and high-quality materials ensure these shoes deliver extended operational life, reduce downtime, and maximize equipment effectiveness in challenging environments.

Key Specifications
- Track Shoe Width: Varies around 780 mm depending on model
- Track Chain Rollers: Made from DIN 41Cr4 steel (40Cr), heat-treated to hardness levels between HRC50-56 for wear resistance
- Wear Pads: Constructed from NM400, a wear-resistant material significantly enhancing the lifespan of the pontoon structure by approximately 1-2 years
- Anti-corrosion Screws: Treated with Dacromet processes and pass salt spray tests up to 1000 hours to ensure long-term durability in wet environments
- Hydraulic Oil Pipes and Fittings: High-quality imported brands with PVC protective wrapping for corrosion and wear resistance, arranged neatly to simplify maintenance

Maintenance Recommendations
To sustain the longevity of swamp shoes:
- Regularly inspect cleats and track chains for wear or damage, replacing worn parts timely
- Keep anti-corrosion treatments intact, reapplying protective coatings if needed in corrosive environments
- Monitor hydraulic pipe arrangements for wear or abrasion, ensuring they remain intact and properly secured
- Clean and lubricate moving parts to prevent premature wear
