Product overview
ZT6-450 type brake slack adjuster (hereinafter referred to as “slack adjuster”) can be widely used in fundamental braking devices of various wagons, whose design conforms to the UIC standard. In braking, the slack adjuster can extend or shrink with the change of the shoe clearance, so as to maintain the brake cylinder piston within the scope of specified stroke and keep normal clearance between the brake shoe and the car wheel, thus ensuring the braking force of the car and improving safe operation. ZT6-450 slack adjuster is composed of two parts – the proper and the control. The ZT6-450 type slack adjuster is designed so that train shock will not cause false take-up or unintentional pay-out of brake shoe clearance. And the brake system will not be activated in the testing of the way.
The basic role of the slack adjuster: In short, it is a lever, but it is made into two sections, one is made into a screw, and the other is made into one end -of -the -frame hollow "tie rod". And adjust the position of the nut on the screw with the changes in the actual gap of the gate, so that the total length of the gate device is elongated or shortened, and the goal of adjusting the gap between the gate to normal values to normal values is achieved.

Product advantages
·CRCC, IRIS, ISO, TSI certification approved
·Good of manually rotated against the external body of the slack adjuster, so that the screw extension increases the gap. Under normal circumstances, due to the automatic adjustment of the gateor, there is no need to adjust the gap between the gates after replacing the gate.
·Good of small volume
·Light weight,43 KG.
·The characteristics of good adjustment performance
·Can be used for various railway trucks
·Replace other UIC slack adjuster.
Slack adjuster is composed of the body part and the control part. The body part is mainly composed of cylindrical body, sleeve, guiding nut spring box, front cover, screw, protective tube, spring, lever, etc. The control part is composed of the control rod and the control rod head. See the figure.
