Crawler Crane Idler

Production introduction

The crawler crane idler is used to guide the track to rotate correctly to prevent track deviation and detailment. Most of crawler crane front idlers also act as track rollers.this can increase the contact area between the track and the ground and reduce the grounding pressure.the surface of crane front idler is made into a smooth surface and the middle arm ring acts as the guide.and the the torus on both sides support the track link.The smaller the distance between the crane idler and the nearest track roller, the better guidance.

Detailed information of crane idler group as below:

Advantages

Each crane idler roller is produced using dished out quality steel plates of generous thickness for maximum strength. An abundance of internal reinforcements sage guard shape is against twist from severe usage such as ripping.

Maximum strength

The idler roller shaft is machined by the utilization of the most modern technological advances known to the industry. Grinding and finishing methods ensure a mirror like finish and tempering with medium to low frequency heat treating equipment guarantees maximum strength.

Cost saving service life

The heavy profiles of idler roller rims are carefully heat treated in depth for extra service life.

Precision care

Each front idler is precision machined to house special high impact low wear bimetallic bushings.

Our crane idlers are applieable to below models:

What are the differences between the friction-welded track roller and the traditional type of track roller?

1. Friction-welding track roller is better in the wear-resistance and has longer working lifetime.

2. Consumption of material
For traditional track roller, the roller bodies are connected by the welding rod.
For friction-welding track roller, the roller bodies are connected by the friction between roller bodies.Friction part of roller will be added more material to make sure roller is conformed to the standard size after friction-welding.

3. Interior parts
For traditional track roller, the welding is done after two processes of fine machining, therefore the requirement to the size of interior parts is not that severe.
For friction-welding track roller, after the welding, there is one more fine ma-chinning with concentric locating to make sure the conformity of inner sizes.And for which, the requirement to the size of interior parts is severe.Interior parts for friction-welding track roller are with higher standard.

4. Differences on the manufacturing processes
