TAIL RAMP POWERPACK / MANUAL LEVER CONTROL PACKAGE
This listing is just for an hydraulic power pack + manual valve.
Powered by 12 or 24 Volt DC this compact Hydraulic Power Pack is ready to fit where you prefer to use a directional control lever(DCV) instead of a full electric control pendant style (see other listings). It is an ideal tail ramp power / control unit. The rams & fittings are not included, as there is no 'one size' fits all ram. Most trailer ramps use a 2.5" Bore ram, but the 'stroke' will vary with your set up. Please see our Cylinder listings. We are happy to quote out a full pack, ready for install. Please call, or email us.
This P & T powerpack is designed to supply an oil flow of 5 Lt/Min at a Pressure of 2500 PSI. The Directional Control Valve has a in built micro switch that automatically starts/ stops the powerpack when the lever is moved. The Directional Control Valves lever will spring back to centre automatically, thus stopping current to the powerpack, and also locking your ramps in place. This powerpack is well sized for most tail loaders. However if your trailer ramps are very large, we also have a high powered powerpack available. The advantage of this higher power, is it's higher flow rate. 9Lpm. This means ramps move quicker, thereby reducing the 'duty cycle' of the power pack. See other listings, & choose P & T model to go with this DCV. You will need to buy this micro switch valve from a stand alone listing.
There are THREE options to choose from with this package;
Single acting control valve. This allows the ramps to come down using only gravity, & uses the powerpack to raise. Advantages of this, is that you only require one hose per cylinder. It will also 'hold' in centre lever position.
Double acting control valve. This will power ramps both up & down, and also 'hold' in centre lever position.
Double Acting + "Float". This is a best option if you ever park on very soft muddy ground. Ramps will power both up &down, and also 'hold' in centre lever position, but it also has a 4th extra position, so that when ramps are down, they are not locked. This is important if ramps are driven on in soft ground. With other two valves, ramps are locked, & a heavy machine in mud can actually bend Ram rods if ramps are not supported firmly.
Please keep in mind all DC powerpacks use a lot of amperage & create a lot of heat. The are designed only for intermittent use. See bottom of this page for an estimate of duty cycle.
Items required additionally;(NOT Supplied) A 1/4" pressure & a 3/8" oil return hose going from the power pack to the Directional Control Valve, two hoses from Directional Control Valve to your rams, often Tee pieces are used for two rams. Adapters to join hoses to Directional Control Valve & the powerpack. Cable, wire for electric hook up. High amp welding cable is ideal from battery to powerpack. These are all parts we make & supply. Contact us for custom length crimped hoses, or buy from our field fit re usable section.
