The performance of the rail platen has been well developed

Rail clips with adjustable by rail clips can overcome the past traditional rail clips in use in fault, traditional platen in use is often directly and rail pressure of the rail steel on steel, after installation can't guarantee the platen and rail have reliable contact, some of the pressure plate after installation can't to adjust the horizontal direction, This is easy to wear after the normal load or thermal expansion and contraction caused by longitudinal movement of the track, resulting in loose plate bolts, plate rotation, resulting in track surface wear and gnawing rail, serious rail breakage, which will also affect the wear of the host wheel and drive mechanism damage. When the adjustable combined rail platen is used, the rail can be fixed in the horizontal direction and the rail position can be adjusted horizontally. For example, the QU80 platen allows the lateral adjustment of the distance to the rail to be 15mm. QU120 platens allow lateral adjustment of the spacing to 20mm on the track. And has the self-locking function, can reliably fix the track, in order to avoid the track in the big wheel pressure when the offset. An elastic force is used to fix the track in the vertical direction. That is, the hot rubber tongue on the track pressure head is made of wear-resistant, oil-resistant, high-temperature resistant and corrosion-resistant synthetic rubber.

The rubber composite pad is laid at the bottom of the rail, and the rail is pre-pressed, so as to prevent the local rail lifting force generated in the movement of the big wheel pressure, resulting in the loosening of the bolt and affecting the damage of each device. It can also allow the track to move longitudinally when the track is subjected to thermal expansion and cold contraction without wear on the platen track, and the bottom surface of the track can keep close contact with the rubber composite pad laid on the track. In order to make the crane can run smoothly, now often use laying welding track, that is, the crane whole section of the track welded into one, there is no segment joint in the middle, and this form of installation requirements are higher, and there is a large heat expansion and cold shrinkage. The debuggable combined track pressing plate is especially suitable for this type of track fixation, which can eliminate the adverse factors caused by the use of welded track.
