Crawler board is commonly used accessories of paver. Today, Xiao Bian introduces ABG paver ABG423 crawler board of construction machinery house.

The common problems in paver work, when the output torque reached enough to balance the resistance torque value, the starting machine speed will be stopped, and on the basis of the continuous effect of the governor, the starting speed of the machine will have some rise.
However, if a wide range of speed drop occurs, that is, the speed value has now dropped to the peak value of torque in the motor characteristic curve, then the speed control mechanism based on the starting machine is not able to make the starting machine speed can be restored.

ABG paver ABG423 crawler board high assurance through a steady flow, through the one-way valve 3 (pressure 0.1MPa) into the lift cylinder, another oil: when the manual control valve 8 is in place, the flow of the one-way valve 3 is small, the oil hydraulic valve 5 to move to the right, the hydraulic oil flow to the other loop.

When the flow direction of the one-way valve 3 is large or the manual reversing valve 8 is in the right position, the lifting cylinder has the oil inlet in the rod cavity, and the ironing plate rises under the action of the solenoid valve 16 and 17, and the flow through the one-way valve 3 accelerates the lifting effect. Relief valve 6 should have a certain pressure to ensure that the reversing valve 5 is in the right position.

Caterpillar track of construction machinery house has 3 advantages:
The first: size standard. The connection dimension of the track plate and the rubber plate and the surface hardness of the steel plate are in line with the relevant standards of the industry, and the steel plate forging has no cracks.
Second: fine machining. Each batch of products has a chemical analysis report, tracked steel plate after painting treatment, the joint surface processing smooth.

Third: perfect design. The rubber on the rubber plate is selected for oil resistance, asphalt resistance, corrosion resistance, diesel resistance, wear resistance, no rubber plate crack, partial shedding phenomenon.
