The transmission of hydraulic oil from the reservoir by the pump through the valves to RAM & CYLINDER which converts the hydraulic pressure into a mechanical force is by means of a HYDRAULIC CIRCUIT. 4. All hydraulic cylinders consists of two basic elements-the outer housing is called the CYLINDER body and the inner sliding element is called the RAM (or piston or plunger) which actually converts the hydraulic pressure into mechanical force and transmits to the desired point for performing the function.

Hydraulic oil is pumped into the cylinder and as more and more oil is forced into the cylinder pressure builds up and when enough oil is force into the cylinder the resultant pressure will cause the ram, plunger or piston to move and consequently lift, press, push, pull or bend any object as the case may be. NOVELTY OF THE INVENTION * This invention of HYDRAULIC HEAD & TOE JACK WITH INTEGRAL PUMP which is used for lifting a load upto 10 ton on head or toe. This Jack has a hydraulic lift of 230 mm (9.05 inches) as explained in diagram No. 4. This has a closed height of 530 mm (20.87 inches) as explained in Diagram No. 3. This Jack has a base size of 164 mm x 265 mm ( 6 ½ X 10 ½ inches) and toe size is 64 mm X 62.5 mm (2 ½ X 2.4 inches) with grooves. The maximum toe height in closed position is mm ( 2 inches) from ground as explained in Diagram No. 2. This Jack has a plunger relief valve set at 11 ton capacity whereby it will start relieving the excess pressure back to tank in the event of overload. This Jack can be operated in any orientation that is vertical, horizontal and upside down (inverted) position. This Jack can be lifted to its full height within 58 strokes of the pump plunger. Positive stop is provided to prevent the hydraulic cylinder from coming out of the housing at maximum lift position. A replaceable saddle on the cylinder head is provided with grooves.
