(1)In order to pick up goods quickly and conveniently, the door frame needs to tilt forward;
When handling the goods, in order to prevent the goods from falling, the door frame needs
to tilt back to ensure the stability of the goods. The forward and backward tilting of the portal
frame is accomplished by tilting the oil cylinder.
(2) The inclined cylinder is composed of piston, cylinder, piston rod, upper cover, lower cover,
pressing nut and other main parts.
(3) There are two oil holes in the inclined cylinder that can be used interchangeably as oil inlet
and outlet holes. The cylinder is divided into a front cavity and a back cavity by the piston.
The back cavity is filled with high-pressure oil when tilting forward, and the front cavity is
filled with high-pressure oil when tilting backward.
