❇️ Appliances of Spare Parts ❇️
In the following, we will mention and introduce some of the most important mentioned tools. For more complete information, contact our consultants to provide the necessary guidance. Floors: are used to connect the brake and wind system to the tractor. Yellow and red tiles cannot be placed together. Their endurance is 8 times and their temperature strength can be changed from 35 to 85 degrees Celsius. Yellow: brake system Red: main system wind circuit + air filter Lifting valve: It is used to adjust the axis of the lift and, in addition to raising and lowering, it adjusts the axis of the balloons in terms of drop or pressure strength. Park lock valve: When necessary, this valve is used to stop or start the trailer. But if the trailer does not have the double booster mechanism, this will not be possible. This feature is available in trailers with the possibility of a double booster.
Red button: It is used to brake the trailer when parking. This button works like a handbrake. (Having a full stop) Pressing this button disables the rear axles. In fact, its double boosters are disabled. When there are special conditions, this stop button should be used to make sure the trailer stops. Because if it is not activated, and the couplings are connected, even if you activate the black emergency button, the brake will remain free and will not stop. So you will face a critical situation.
Black button: This button is used in emergency work. If the yellow rudder was inactive or the wind system was cut off in any direction, the black button is used for emergency movement. Because the suspension of the trailer wind system automatically prevents the trailer from moving. Therefore, we need to activate this button for emergency movement.
Lift axle control valve: This tool is used to adjust the lift height in the trailer. Actually, according to the amount of cargo, the height and air pressure of its balloons are adjusted. If this tool is physical and not automatic, it will determine its height by measuring (through the valve) the amount of load.
