Main Feature

  • Automatic compensation device that can automatically adjust the lever length when the brake pads wear to ensure the safety travel of the brake and effectively prevent the wear of the brake pads causing the loss of braking power.
  • Automatic arc face centering device for the brake shoe, which avoids the brake lining floating on the surface of the brake drum during the opening of the brake and automatically centers without manual adjustment and maintenance.
  • Interlocking equalizing device for the stroke, which automatically adjusts the gap between the brake shoe and the brake drum on both sides to ensure that the brake lining surface is completely separated from the surface of the brake drum during the release, and avoids the phenomenon of one-sided wear of the brake lining.
  • Adjustable braking time device that can adjust the different braking times of the brake according to the needs of various working conditions.

 

OPERATING CONDITION

  • Automatic compensation device, when the brake pads are worn, can automatically adjust the length of the tie rod to ensure the safe travel of the brake, effectively prevent the brake force failure caused by the wear of the brake pads.
  • Automatic centering device for brake shoe arc surface, avoids brake pad floating on the surface of brake wheel when brake is opened, and automatic centering does not require manual adjustment and maintonance.
  • interlocking equal retraction equalizing device automatically adjusts the clearance between brake shoe and brake wheel on both sides, When loosening the brake, it ensures that the arc surface of brake pad is completely separated from the surface of brake wheel and avoids brake pad one-sided eccentric wear.
  •  Adjustable braking time device. which can adjust different braking time according to various operating conditions.
