ZFZ2200(2600)/ 16/24 Hydraulic Support for Top Coal Caving
Product description: the bracket adopts a simple pendulum mechanism, which simplifies the structure of the bracket, reduces the weight, and has enough ventilation section and pedestrian space; Adopt integral top beam and add integral steel parts. Both the top beam and the tail beam are provided with movable side guard plates, which can realize full sealing and play a role in righting the support. The tail beam is provided with a swinging jack and a movable inserting plate, and the swinging amount and expansion amount of the tail beam are controlled by the jack, so that the size of the top coal caving port is changed and the coal caving effect is enhanced; An anti-falling jack is added to the top beam, and two holes are opened in the front axle, which can be used at an inclination angle of 20 -35 degrees, thus improving the anti-sliding and anti-falling function of the bracket and adapting to a larger inclination angle; The floating piston push rod mechanism is adopted for pushing, which makes the push-pull frame more balanced, improves the connecting force with the conveyor and protects the safety of the conveyor. Support greatly meets the needs of coal mine, and it is a new product in top coal caving support.
The support is suitable for coal seams with dip angle less than 25, coal seam thickness of 3.5- 15m and coal hardness f= 1-3. There is no need to lay nets: the dip angle of coal seam is between 20-35 degrees.
