Cylinder Descriptive Background Information


The first order of business in a JACKING SYSTEM is to pick the right Ram/Cylinder for the job you need to do.

Generally speaking, the cylinders are rated at 10,000 PSI of Hydraulic Fluid Pressure and start at 5 ton capacity and move on up to over 1000 tons.
To lift greater loads they can be ganged together - Three 500 ton Rams will output 1500 tons of Force and so on.

Because of different needs several different styles of cylinders have evolved.


STANDARD RAMS


CutAway Cylinder
For simple Load Pushing or Lifting STANDARD SPRING RETURN or LOAD RETURN Rams will do the job.

As the names imply SPRING RETURN Rams have a spring (internally) that helps close the ram once the pressure is released.

LOAD RETURN Rams require that either the Load be left on to close the ram or else some means of force will be needed to retract the ram (for instance, standing on it or pushing by hand).

For SPRING RETURN Images, Specs & Prices choose:

ENERPAC SPRING RETURN RAMS
POWER TEAM SPRING RETURN RAMS
SIMPLEX SPRING RETURN RAMS

For LOAD RETURN Images, Specs & Prices choose:

ENERPAC LOAD RETURN RAMS
POWER TEAM LOAD RETURN RAMS
SIMPLEX LOAD RETURN RAMS


LOW & ULTRA LOW PROFILE RAMS


Often a very large machine or load needing lifting will have a very low clearance underneath it with which to work with. A Standard sized Ram will not fit under the beast and a special LOW PROFILE or ULTRA LOW PROFILE ram is required.

For LOW PROFILE Images, Specs & Prices choose:

ENERPAC LOW PROFILE RAMS
POWER TEAM LOW PROFILE RAMS
SIMPLEX LOW PROFILE RAMS

For ULTRA LOW PROFILE Images, Specs & Prices choose:

ENERPAC ULTRA LOW PROFILE RAMS

Low Cylinder

LOCK NUT RAMS


Lock Nut Cylinder
Sometimes it is necessary to lift a large load and leave it up for several hours, days, weeks or even longer. Rather than leave the pump, hoses, accessories and Rams themselves under pressure for so long a very simple and quite clever holding screw collar has been built into LOCK NUT Rams. With it the user is able to lift a load hydraulically then HOLD the load mechanically with the LOCK NUT while the pressure is released, and perhaps the pump is moved on to do other work.

POWER TEAM LOCK NUT RAMS
SIMPLEX LOCK NUT RAMS


DOUBLE ACTING RAMS


Some jobs such as production Pressing require that a load be pressed then the Ram be quickly retracted to remove the first item so the next item can be set into the press to repeat the operation. Rather than wait for a Spring Return Ram to do the job a DOUBLE ACTING RAM is used for speed of operation.
Here's how it works - The pump (equipped with a special valve to operate Double Acting Rams) switches the oil pressure from the bottom of the Ram to a port at the top of the Ram and it, more or less, throws the Ram into "Reverse" and quickly closes it.

Also, DOUBLE ACTING RAMS offer both PUSHING a load with pressure and PULLING a Load with pressure. But because of the Laws of Physics one gets two DIFFERENT pressure Forces when pushing or pulling.
What happens is this - When PUSHING the oil is filling the entire bottom of the Ram Cylinder. However when PULLING (or Retracting) the oil is only filling the small gap between the Cylinder wall and the Piston itself instead of the whole Cylinder resulting in much less Force, "roughly" a 5 to 1 Force drop. Meaning you might be able to PUSH with 20 tons but only PULL with 4 tons.

ENERPAC DOUBLE ACTING RAMS
POWER TEAM DOUBLE ACTING RAMS
SIMPLEX DOUBLE ACTING RAMS

Double Acting Cylinder

HOLLOW RAMS


Hollow Cylinder As the name indicates, HOLLOW RAMS have a hole through the middle of them through which threaded rods or steel cable can be passed to perform heavy duty pulling operations.

DOUBLE ACTING HOLLOW RAMS are also available for quickly releasing Force and repositioning.

For SINGLE ACTING Images, Specs & Prices choose:

ENERPAC HOLLOW SINGLE ACTING RAMS
POWER TEAM HOLLOW SINGLE ACTING RAMS
SIMPLEX HOLLOW SINGLE ACTING RAMS

For DOUBLE ACTING Images, Specs & Prices choose:

ENERPAC HOLLOW DOUBLE ACTING RAMS
POWER TEAM HOLLOW DOUBLE ACTING RAMS
SIMPLEX HOLLOW DOUBLE ACTING RAMS


ALUMINUM RAMS


ALUMINUM RAMS are becoming popular for their dramatic decrease in weight versus Standard steel Rams. They are particularly nice if one has to carry the Rams around the worksite a great deal and/or is constantly repositioning them.

An important downside to ALUMINUM RAMS is that they don't handle Side Loads well - If you're Pushing or Lifting off center Loads stick with Steel!

For Images, Specs & Prices choose:

ENERPAC ALUMINUM RAMS
POWER TEAM ALUMINUM RAMS
SIMPLEX ALUMINUM RAMS

Aluminum Cylinder

SPREADER RAMS


Spreader Cylinder SPREADER RAMS (also called Duckbills) are used somewhat like CrowBars for getting into a very tight spot and nudging it open.
With their unique design they are able to slip into places that a normal Hydraulic Ram couldn't possibly fit, but with much less Force than conventional Rams - Usually 1/2 to 1 ton.
