Liebherr HS882 HS882HD Sprocket Drive Wheel for Crawler Crane

Details of HS882 HS882HD Sprocket

Production of HS882 HS882HD Sprocket

• Pig iron smelting. Melt raw material into liquid iron at high temperature.
• Sand casting. Making mold – Box mold – Combining box – Pouring – Sand dropping.
• Heat treatment. Quenching, heat the casting to a certain temperature and then cool it quickly to improve hardness and strength. Tempering, heat the quenched casting to a lower temperature again and keep it warm for a period of time to eliminate quenching stress and improve toughness.
• Rough machining and finished machining, achieve the required size and accuracy.
• Quality inspection. Inspect the size, hardness, metallographic structure, and other items of the processed drive wheel to ensure that the product quality meets the requirements.
• Paint and packing.

Advantages of Crawler Crane Sprocket:

• Efficient Traction and Anti-Slip. The sprocket drives the tracks by engaging with the track pins or track shoes directly, preventing slippage on complex surfaces (muddy, loose soil) and provide powerful driving force.
• Heavy Load Capacity and Stability. The sprocket distributes the power from the hydraulic motor to the tracks, and combined with the large ground contact area of the tracks, enables the crawler crane to move while carrying heavy loads.
• High Climbing Ability. Due to the direct power connection and high traction, the sprocket allows the crawler crane to operate stably on slopes, adapting to mountainous areas or construction sites.
• Compact Structure and High Wear Resistance. The sprocket is usually cast from high-strength alloy steel, ensuring wear resistance under long-term load and high friction, reducing downtime for maintenance.
• Low Ground Pressure. In conjunction with the track shoe design, the sprocket system allows large machinery to adapt to softer or uneven ground without excessive sinking.
