LOCATION AND DESCRIPTION OF MAJOR COMPONENTS CONTINUED
The pump assembly (Figure 1, Item 13) is a reciprocating piston type unit, incorporating ball inlet and discharge
valves. Two adjustable relief valves are included to maintain an operating pressure of 1750 psi.
CYLINDER AND RAM ASSEMBLY
The cylinder and ram assembly (Figure 1, Item 5) transforms the hydraulic oil pressure of the pump into a vertical
lifting force. This is effected by the ram, which is caused to rise by the incoming oil at the bottom of the cylinder.
TRIPOD/FOOT AND CASTER ASSEMBLIES
The tripod assembly and the three foot assemblies, along with the necessary braces and links, make up the struc-
tural members of the tripod hydraulic jack. These members provide the ¿rm foundation required to support the
cylinder and ram assembly during the lifting operation.
