Function of the Liebherr HS852 Track Roller
- Support the weight. The track roller transfers the weight of the crawler crane to the tracks, which then transfers the weight to the ground.
- Guide the tracks. Track roller guides the tracks along the predetermined path to ensure the smooth travel of the machine.
- Bear impact and friction. When the rollers travel on uneven roads, they will be impacted by the ground and also bear the friction between the tracks and the wheel rims.
- Prevent derailment. The structural design of the track roller can prevent the tracks from detaching from the wheels during movement, ensuring the normal operation of the crawler crane.
Production of Liebherr HS852 Track Roller
- Raw Material Preparation. Prepare high-strength forged steel raw materials.
- Roller Body Forming. Manufacture the track roller blank using forging methods.
- Perform rough and finish machining on the blank, processing key parts such as bearing seats and sealing grooves.
- Heat Treatment. Quench and temper the roller body surface to improve wear resistance and hardness.
- Bearing and Seal Installation. Install roller bearings (or sliding bearings) and sliding ring seals into the roller body.
- Assembly and Closing. Insert the roller shaft into the roller body, install the retaining ring and plug, forming a complete track roller assembly.
- Sealing Test. Conduct an airtightness test on the assembled track roller to ensure sealing performance.
- Surface Treatment. Perform surface treatments such as rust removal and painting.
Why choose us for Liebherr Track Roller?
- Adopt high-level raw material 40Mn, forged roller body, strong hardness, and wear-resistance.
- Whole quenching and tempering, and surface hardening, ensure that the place that comes into contact with the track chain is more wear-resistant.
- Pure copper bushing, reducing friction and extending the service life of the bottom rollers.
- Good O-ring and floating oil seals offer better sealing performance, reducing the risk of oil leakage.
