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.

Resolving excess production capacity in the steel and coal industries The inter-ministerial joint meeting on poverty alleviation and development work held a national video and telephone conference in Beijing on March 1. At the meeting, Xu Shaoshi, director of the National Development and Reform Commission, emphasized that we must step up efforts to reduce overcapacity and ensure that the annual targets and tasks are completed.
The meeting reported on the current progress of China's steel and coal overcapacity reduction. In terms of steel, official data shows that in this month, individual steel-producing regions and central enterprises across the country completed a cumulative reduction of 10,000 tons of steelmaking capacity, accounting for 10% of the annual task volume. Among them, Zhejiang and other provinces have completed their full-year tasks, Hebei, Liaoning and other provinces have work progress of between %% and more. The work of resolving excess steel production capacity has not yet been substantially started.
In terms of coal, as of the end of the month, more than 10,000 tons of coal production capacity across the country had been withdrawn, completing 10% of the annual task. The progress of overcapacity reduction varies across regions. Some provinces have completed 10% of the annual task, while the coal overcapacity reduction work in Inner Mongolia, Guangxi and other places has just started. The amount of coal overcapacity reduction tasks arranged by various localities in the fourth quarter accounted for more than % of the whole year, and the monthly proportion accounted for more than one-third.
Xu Shaoshi pointed out that the reason why the progress of overcapacity reduction is uneven across regions is that a few regions do not fully understand the importance and urgency of overcapacity reduction and are worried that overcapacity reduction will affect economic development. This is also related to the fact that some regions and enterprises are affected by the price of steel and coal. The rebound is related to the wavering of determination to cut overcapacity.
