Rollers by Qiming Casting

Electric shovel rollers play a dual role in supporting the machine’s weight and guiding the track’s underside. They are crucial in ensuring a smooth glide for the track shoes, facilitating effortless movement and uniform weight distribution across the track framework. These rollers enhance the weight distribution capabilities of tracked vehicles, leading to reduced ground pressure and enhanced stability.

Drawing from our rich experience in field casting, Qiming Casting are positioned as a leading provider of specialized steel casting services.

The “Rollers” of an electric shovel usually refer to the rollers in its crawler system, including idler rollers and drive rollers, etc. These rollers play a key role in the operation of the electric shovel.

Function

  • Rollers: support the tracks of the electric shovel, reduce the sagging and wear of the tracks during operation, and help guide to ensure that the tracks are properly aligned.
  • Drive wheels: engage with the tracks and provide power to drive the electric shovel forward or backward.
  • Reduce friction and wear:
    Rollers reduce wear and extend the service life of the tracks and the body by reducing direct friction between the tracks and the ground or the body of the vehicle.
  • Improve stability:
    By evenly distributing the weight of the electric shovel, Rollers help improve the stability and maneuverability of the vehicle on various terrains.
  • Power transmission:
    The drive wheels transmit the power of the engine to the tracks, thereby driving the electric shovel to move.

Types

  • Idler Rollers:
    Includes upper and lower idlers, located above and below the track, respectively, to support and guide.
  • Drive Rollers:
    Located at the rear or front end of the track system, transmitting power through engagement with the track.
  • Carrier Rollers:
    Directly in contact with the ground, supporting the weight of the electric shovel and reducing the pressure of the track on the ground.

Materials and Design

  • Material:
    Usually made of high-strength steel, such as alloy steel, to withstand heavy loads and impacts.
    The surface may be specially treated, such as heat treated, to increase hardness and wear resistance.
  • Design:
    The design needs to consider durability, load-bearing capacity and impact resistance.
    The drive wheels usually have special tooth shapes to effectively mesh with the track.

The rollers of an electric shovel are an important part of its traveling system and have a direct impact on the overall performance and reliability of the electric shovel. Therefore, it is very important to choose the right rollers and perform correct maintenance and care. Qiming Casting, as a professional electric shovel parts manufacturer, can provide customers with high-quality and stable rollers.
