Crane Bottom Roller
Crawler crane bottom rollers, also known as track rollers or lower rollers, are the core load-bearing parts of the crane undercarriage. They are typically installed at the bottom of the track crane's underframe, evenly distributing the weight of the entire crane to the track pads and guiding the track to wind smoothly and steadily during movement. They are a crucial link connecting the chassis and the track shoe.

What are crawler crane bottom rollers?
Crawler crane bottom rollers, also known as track rollers or lower rollers, are the core load-bearing parts of the crane undercarriage. They are typically installed at the bottom of the track crane's underframe, evenly distributing the weight of the entire crane to the track pads and guiding the track to wind smoothly and steadily during movement. They are a crucial link connecting the chassis and the track shoe.
Main functions of crane bottom rollers:
Supporting the weight of the crawler crane: As a primary load-bearing part, support rollers bear the crane's own weight and the immense pressure during lifting, evenly distributing it to the crane track pads to prevent the equipment from sinking due to excessive localized pressure.
Ensuring smooth movement: The crane's bottom rollers roll on the track tracks, enabling the track crane to move and turn smoothly on uneven construction sites or muddy roads.
Assisting track operation: Working in conjunction with the sprocket and idler, they guide the track forward in a predetermined direction, reducing track friction and improving transmission efficiency.
