Jiaozuo brake

Additional devices

Various additional devices can be installed according to user needs to meet different work needs;

Rising or falling valve: the rising valve "H", the falling valve "S" or the rising and falling valves "H, S" can extend the rising and Fall time steplessly, and the adjustable value can reach 10-20 times of the rated value. The valve is adjusted externally. The rising and Fall time time of the thruster with valve will be extended, the short stroke will be extended by 0.1-0.2s, and the long stroke will be extended by 0.2-0.4s;

Brake spring: It generates braking force, and the spring force listed in the technical parameters is 1/3 of the rising stroke (2/3 of the falling stroke);

Return spring: The working principle is the same as C-spring, but the return spring force is relatively small;

Cushion spring: (only applicable to short stroke) mainly regulates the braking process. The non periodic transient process of buffering braking ensures smooth braking. It replaces the connecting block of the push rod and is installed on the piston rod without changing the stroke of the pusher.

Heater: In areas with ambient temperatures below -20 ℃, additional heaters can be installed according to user needs. The heaters are AC200V or AC110V voltage, and should be specified when ordering. The temperature control and adjustment method is chosen by the user themselves;

Travel switch: According to user requirements, the pusher can be equipped with a mechanical travel switch.
