Function of the 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.
