Porto-Power Operation and Use Session Reference: 1 Topic: Porto-Power Operation and Use Time Required: Four Hours Materials:    • Complete Porto-power Set    • Assorted Cribbing    • 1-2 Acquired Vehicles...

  6. Female Adapter – adapter threaded on inside of female end to permit attachment to ram plunger;

      male end fits inside extension.

  7. Flat Base – threaded flat attachment used where larger base needed for ram cylinder or plunger.

  8. Hose - transmits oil under pressure from pump to ram, wedgie, or spreader; flexible and reinforced

      to withstand internal pressure of system.

  9. Lock-on Connector – used to connect two extensions together; lock pins used to hold extensions

      in place on connector.

  10. Lock Pin – used to hold extension onto lock-on connector or male or female adapter.

  11. Male Adapter – adapter threaded on outside of male end to permit attachment inside ram

        cylinder; other male end fits inside extension.

  12. 90-degree V-Base – threaded V-shaped base with notches on both sides for gripping on round


  13. Pipe Coupling – used to connect two extensions together using threads on outside of each


  14. Plunger Toe – threaded attachment for ram plunger to permit spreading in tight areas.

  15. Pump - hand operated unit that creates hydraulic pressure in system by operating handle.

  16. Ram – used primarily for spreading in all directions and in any position; complete range of

        capacities from l-1/2 through 50 tons (only component of system to operate at capacity); can also

        be used for limited pulling; one end of the ram threaded on outside of cylinder while other end

        threaded on inside; end of plunger also threaded; travel distance of plunger eight inches; when

        used with extension, capacity of ram reduced by 50%.

  17. Rubber Flex Head – threaded round rubber attachment for end of ram plunger or extension.

  18. Serrated Saddle – threaded round serrated base for plunger.

  19. Single Chain Plate – threaded attachment for cylinder to permit chain to be attached to each end;

        plunger pushes against object to create tightening.

  20. Slip Lock Extension - adjustable extension inserted inside extension and secured with lock pin;

        adjustment mechanism threaded with quick release to extend.

  21. Smooth Saddle – threaded round smooth base for plunger.

  22. Spee-D-Coupler – threaded coupling used to connect hose to ram, wedgie, or spreaders.

  23. Spreader – device used for widening opening; spreader has opening distance of approximately

        twelve inches and capacity of approximately 1,200 lbs.

  24. Wedge Head – threaded wedge-shaped attachment for ram plunger or extension with notch in

        center for gripping.

  25. Wedgie - small spreader (sometimes called a duckbill) has opening distance of approximately

        three inches; capacity of approximately 600 lbs.

B. Care and Maintenance

  1. Protect threads and couplings with proper protective devices or caps

  2 Avoid overpowering attachments

  3. Hydraulic lines should never be disconnected while under pressure

  4. Attachments tightened by hand utilizing Spee-DCouplers

  5. When utilizing extension tubes, utilize lock on connectors or lock pins

  6. Tape measurements should be taken to ascertain desired extension reach prior to assembly

  7. Check jack oil level - add SAE 10 motor oil if needed to level of notch on stem of filler plug

  8. Do not overfill pumps beyond recommended capacity



A. Principles of Operation

  1. Do not overpower pump with pipe attachments or additional weight application; stop pumping

      when pumping becomes more difficult

  2. Spreaders and wedgies normally are the most misused piece of equipment utilized with portopower


  3. Pump handle for application of force. When using spreader or wedgie, hold pump in hands with

      hose pointing down, and squeeze pump handle against pump housing. Stop pumping when   

      resistance is felt.

B. Protection of Equipment

  1. Do not overload rams, use largest ram and base as possible within available space
