2.Application:
QW, QWZ5 series pneumatic drum brakes, widely to brake or stop in various crane, belt transport, port handling and metallurgical machinery with gas source.




3.Main Feature:
1) the safe and reliable performance, smooth braking, high frequency of action;
2) the main drivers of the hinge point is equipped with self-lubricating bearings, high transmission efficiency, long life, the use of the process without lubrication;
3) Equalize the clearance of the device of interlocking tile with the digital device automatically, you can always keep the pad on both sides to equalize the clearance without the need to adjust completely to avoid sticking to brake wheel side brake pads due to retire from the unequal phenomenon;
