It is an ideal tail ramp power/control unit. The rams, hose & fittings are included.

This Single or double Acting power Unit is designed to supply an oil flow of 5 Lt/Min at a Pressure of 2,800 PSI.

On the Single Acting Unit: When you press the down button, the powerpack will not start, but the ramps will lower with gravity.

On the Double Acting Unit: When you press the down button, the powerpack will also start, and the ramps will be driven down.

The adjustable Knob on the "reverse check flow control Valve" : will allow you to control and set the descent or ramp lowering speed.

Pressing the Up button on the pendant controller: will automatically Start the Hydraulic power Unit and the ramps will raise (possibly at different rates to the top)
They will then hydraulically lock in place when pendant button is released.

Please note with this set up, ramps are hydraulically locked, & a heavy machine in mud can actually bend Ram rods if ramps sink or are not supported firmly on the ground. Click here to see our D/A Float ramp package D/A ramp package

Also supplied are safety 'burst' valves which insert into the bottom ram ports. These stop the ramps falling if ever a hose is damaged or ripped of. We supply hose, fittings & field fit reusable hose tails that allow you to custom make your own hoses.

Please contact us for custom-length crimped hoses,

Please keep in mind all DC Hydraulic power packs require High amperage & create a lot of heat.
They are designed only for intermittent use.
See the bottom of this page for an estimate of the duty cycle.




How Do I Work Out What Stroke Rams I Need?

The measurements of the ram you need to take note of, are the 'open & closed' sizes.

These are measured from pin to pin with the ram fully closed & then fully extended.



Mark a spot on the rear of the trailer where you are going to weld your 1" thick ram bottom mount.



Then, mark a spot up on the ramps for the top mount, ie for a 28” ram,

mark at 1733mm with ramp in an upright position. If possible weld mount where the ram is fully extended, this way, the ram's 6-tonne force is contained on full extension.

Then, drop the ramp on the ground, and use our given 'closed' measurements to mark in pen or tape a spot on the ramp.

Keep in mind, you need to leave a few inches of the rod showing when the ramp is on the ground, this is to allow for uneven ground, etc.

Then lift the ramp, & again use our 'Open measurement to see what ram has the closest open & closed measurements to suit your build.

There are two photos of a customer's ramps below. These rams are a 28" stroke. As you can see when ramps are on flat hard ground, there are several inches of ram travel left. This means if ramps ever had to be lowered onto sloping ground, they could further descend.

Intermittent use only!
e.g. Mini Cranes, Tail Gate Loaders, Ramps on trailers and low loaders Camper van or camper trailer leveling or any other hydraulic circuit requiring intermittent use, low flow, and high-pressure hydraulic oil.


This Unit is capable of generating up to 200 Bar (3000 PSI) Pressure at a reduced flow rate.
Pressure relief is set at 2500 psi as standard
