Whether it is a compressed garbage truck or other special vehicles, household vehicles, etc., there are handbrakes, and this handbrake must also be used, so don't underestimate this handbrake!
The professional name of the handbrake is the parking brake, and its working principle is to use a steel wire to connect to the rear brake shoe to brake the car. A return spring is also used in conjunction with the handbrake. When the handbrake is pulled up to brake, the spring is elongated; when the handbrake is released, the spring returns to its original length.
Friendly reminder: It is not suitable to use the handbrake for a long time. Long-term use of the handbrake will deform the steel wire and reduce the effectiveness of the handbrake; in addition, it is not suitable to use the handbrake when parking for a long time, especially when parking on a slope for a long time. The correct approach is to first apply the handbrake, then "eye" in the front and back of the wheel, release the handbrake after making sure to stop, and put the gear to forward or reverse gear.
The method to manually detect whether the hand brake function of the compression garbage truck is normal is as follows:
Drive the compression garbage truck to a steep road, first step on the brake, put the gear in neutral, apply the handbrake, and then release the footbrake. If the car does not slide, the handbrake is effective. If there is a small distance of sliding and then parking, the handbrake is also considered normal. Otherwise, it is time to go to the service station for overhaul.
