Pneumatic car arrester
Product description of pneumatic car arrester
Series pneumatic car arrester is an indispensable safety protection device in the process of coal mine rail transportation and is used for coal mine transportation. During the route, it controls the positioning and stopping of the minecart, prevents the minecart from sliding away, divides the minecart and removes the hook, etc. The series of pneumatic car arresters are wheel blockers. This device uses gas power to open and close the wheel blocks, which can easily block and stop the mine cars, thus providing an effective guarantee for the safety of coal mine rail transportation. This product has been widely used in coal mining enterprises across the country.
The series of pneumatic car arresters include pneumatic, manual universal type, simple type, and two-way blocking type.
Structural features of pneumatic car arrester
.Simple structure, low cost, easy installation and maintenance
.Pneumatic operation, labor-saving operation, safe and reliable.
Working Principle of Pneumatic Car Arrester
The wheel blocks of the series of pneumatic car arresters are designed on the outside of the track. The working principle is to pull the control valve of the air control box, and the cylinder pushes the wheel blocks to open. When the mine car passes , reversely pull the control valve of the pneumatic control box, and the cylinder pushes the blocking wheel block to close, thereby blocking and stopping the mine car.
