3. Lateral Tilt Assembly - The lateral tilt assem-
bly consists of two cylinders, pistons and connect-
ing rods. The connecting rods attach to the lateral
tilt lever which connects to the table side frames.
When hydraulic fluid is pumped into one cylinder,
the piston and connecting rod pushes the lateral tilt
lever which tilts the table top to one side. To tilt the
table top in the opposite direction, fluid is pumped
into the opposite cylinder. See figure 1-12.
5. Brake Cylinders - The brake cylinders are
single action type similar to the elevation cylinder.
The movable piston's ram is connected to a brake
pad. See figure 1-14. Oil pumped into the top of the
cylinder pushes the piston down raising the table
base off its casters. An internal return spring on the
bottom of the piston, pushes the piston up to return
the oil through the mini-valve to the reservoir.
Figure 1-12. Lateral Tilt Cylinder Assembly
4. Elevation Cylinder - This single action cylin-
der does not have hydraulic fluid on both sides of
the piston. It depends on the weight of the table top
assembly to lower it.
The cylinder is set in the center of the elevation
main column. The cylinder is elevated by the driven
force of the oil pressure. When lowering, the oil that
is accumulated in the cylinder is returned to the oil
reservoir through the mini-valve due to the table top
weight.
A slider support assembly is used to support the
weight of the upper table section. A stainless steel
shroud covers the flexible hydraulic hoses and
slider. See figure 1-13.

h. Elevation Cylinder Return Circuit
Three-way (single check valve type) mini-valves
control both the elevation and return circuits. The
elevation circuit operation within the mini-valve is
identical to the operation of the four-way valves
previously described (inlet pressure opens the
check valve allowing the oil to enter the cylinder).
In the return position, inlet pressure pushes the
pilot plunger up and opens the return check valve.
See figure 1-15. The open check valve allows a
path for the oil in the elevation cylinder to return to
the reservoir. When the pilot plunger valve is
opened, the continuing pump pressure opens the
pressure relief valve which provides a return oil
path to the reservoir.
