Porto-Power Operation and Use

  2. Do not overextend ram. Empty space should be filled prior to application of force. (This assures

      most efficient use of force)

  3. Spring retaining screws on 20 and 50 ton rams should never be tampered with

  4. Refrain from utilizing excessive off center loads; try to work at right angle of load

  5. Do not abuse hose by dropping heavy equipment or kinking lines in such manner as to damage


  6. Provide adequate clearances while working with equipment and do not drag hose lines across

       jagged materials

  7. Maintain clean oil lines by utilizing dust caps

  8. Dress damaged threads and protect from additional damage by utilizing guards

  9. Keep equipment away from fire and heat sources as it will break down packing and weaken


  10. Never attempt to lift a load that exceeds the capacity of your ram. Overloading causes cracked

       cylinders, blown cups, bent plungers

  11. Pump carefully. When you feel that you have to pump unusually hard - stop operation. Adjust

        setup so that off-center load is not as great. Excessive off-center loads produce considerable

        strain on the ram plunger and extension tubes.

  12. Do not carry Porto-power unit by hose.

  13. Collapse ram if connected to pump, permitting oil to flow back into pump. Clamp pump at foot

        bracket in vise as shown. Remove filler plug at end of pump. Add hydraulic oil until it is level with

        notch on stem of filler plug, using the stem as a dipstick.

C. Operation of Porto-power Units

  1. Porto-power attachments can be threaded to the top of the ram plunger, top of the ram or into the

      ram base. While assembling combinations always screw attachments as far down as possible.

  2. When using Lock-On tubing for push operations slip speedy Lock-On Connectors and Lock-On

       Adapters between extensions or extensions and ram. For direct pull operations slip Lock Pins

       through drilled holes.

  3. Operation

       a. Close release valve finger-tight by turning knob near hose end of pump clockwise.

       b. Hold pump in any position, horizontal to vertical with hose end down.

       c. Release valve for lowering load by turning knob near hose end of pump counterclockwise.



A. The Porto-power is a device used primarily to displace members of a wrecked motor vehicle. By exerting a force between two members of a wreck, one or both will generally distort or displace allowing better access to an entangled victim.

B. The most widely used accessory for the porto-power is the spreader or wedgie. The device allows a good deal of displacement with application of force. Most spreaders or wedgies are levered so that cylinder ram travel is amplified. Of course, when this is the case there is reduction of force at the tips.

C. The hydraulic hose and couplings are generally selfsealing ball and needle connectors to limit the amount of hydraulic fluid lost during connection and disconnection and the amount of air entering the system. Usually the ball is spring mounted and must be displaced by the needle before the couplers mate. After the couplings are attached, they must be secured by tightening the coupling nut so that the system will not leak.

D. To use the porto-power, there must be an adequate amount of hydraulic oil supplied to the pump. If this is present, the pressure release valve must be closed, usually by turning a relief valve clockwise until it seats.

E. Use Tips

  1. There should always be at least two persons operating the device, one with the ram to monitor the

      progress, the other with the pump.

  2. When using the spreaders to pop open a door, remember that the door will release only after

      considerable stress is placed on the vehicle frame.  When the door finally does open, it does so

      with much force. The pump operator should lean against the door to reduce the violence of the

      door opening. The pump operator should be positioned behind the jaw operator and slightly to the
