Profile
YT4-8A Hydraulic pusher is a mine mobile device relates to mine area. The structure of the cylinder wall
at the front and rear in the same direction are respectively fixed with front and rear hydraulic valves and hydraulic valves,
the valve between the two opposite sides of the outer wall of the fixed cylinder with a positioning axis Between
the two valve the two opposite sides of the cylinder wallfixed with positioning axes; cylinder by positioning axes located on
the bracket lengthwise hole; holder fixed with the bottom floor, floor near the end of the piston rod upturned;
holder fixed on top of the top seat with choking, choking the top portion of the groove structure seat tilted back,
and with the horizontal angle of 20 ° -24 °.
The utility model design is reasonable, hydraulic liquid injection gun injection fluid and the cylinder separation,
push the slide is easy to move the cylinder adjustable at both ends; piston rod connected with the block of coal plates normal contacts,
extended equipment life.
