            lift or not to lift, that is the question
 Dr Gavin Bailey (RV8 BRG 0766 and V8 Glacier White 0199) from 
            Surrey describes how he tracked down a hydraulic lift and has found 
            it very useful. (Jun 04)
 
 After 
            a number of years dragging a trolley jack around my driveway, and 
            latterly my garage, to lift my MGBGTV8 onto axle stands, and even 
            then having limited clearance underneath to work on the car, the thought 
            of an arrangement that would give greater access was of increasing 
            appeal. From my early days of working on cars in my father's garage, 
            I had long lusted after some kind of ramp or pit, and following a 
            recent move to a house with a garage that had sufficient space to 
            accommodate such an arrangement, I started to look in earnest at the 
            various options.
 
 What are 
            the ramp or pit options?
 If one wants good access to the underside of the car, there are really 
            only two serious alternatives: some form of pit sunk into the garage 
            floor with boards covering it when it's not in use; a ramp to lift 
            the car off the ground. The latter come in two basic forms - the four 
            post variety which you drive on and which lifts the whole car off 
            the ground, wheels in channels and which is a necessity for MoT testing 
            stations; and the two post variety or variations on the theme which 
            have swinging arms with rubber pads which when placed under the jacking 
            points, allow you to raise the car off the ground. The latter option 
            crucially, allows the wheels to hang free giving good access to the 
            brakes and suspension.

 Having 
            explored the options, I was quickly able to rule out a pit, as even 
            with the launch of the excellent 'Mechmate' (which is essentially 
            a lined fibreglass moulding for the pit), they all required

 a significant 
            amount of excavation which was a non-starter with my existing garage. 
            I then started to look at the other option of a lift which had to 
            be compact enough to operate in my garage which although wide, had 
            limited headroom given the rafter arrangement supporting the roof.
 
 As chance 
            would have it I came across an AL-2006 'portable' hydraulic ramp 
            made by Autec of Holland on Holden Classic & Vintage's stand 
            at the Goodwood Festival of Speed. The web addresses are:

 Their display attracted a great deal of attention as the lift was 
            supporting their large Transit van. Although I was impressed with 
            the engineering, I was not ready at that point to shell out the £1,200 
            (now £925 + VAT), they were asking for it. Being a disciple 
            of eBay, I started to look for second-hand ramps, and quickly found 
            that there were many advertised for sale, commonly coming from garages 
            that were closing down. After a short search I was lucky enough to 
            find one second-hand on eBay, and eventually ended up paying just 
            over half the new price for a ramp that was only a few years old, 
            having had only light occasional use. I would mention at this point 
            that one needs to be careful when buying second-hand equipment of 
            this kind, ensuring that the equipment has been regularly serviced 
            and is safe to use. One can take no chances with a ramp that is going 
            to support the weight of a motor vehicle, especially when you're going 
            to be

 working underneath it! After getting the lift home (although 
              described as 'portable', four of us just managed to lift it into 
              my 6x4 trailer), I installed it in my garage. After changing the 
              hydraulic fluid it was ready to use.
 
 So 
              how does it work?
 From the photographs you can see it is essentially comprises a steel 
              frame with a large hydraulic ram that lifts the platform to which 
              four swinging arms carrying rubber jacking pads are attached. The 
              ram is connected to a separate single-phase 240v hydraulic control 
              unit which has two switches - one to power up the unit, and a separate 
              toggle to
 lift or lower the ram. To use the lift, you simply drive the car 
              over the lift, swing the arms out, and position the rubber jacking 
              pads (which slide along the lifting arms thus offering a multitude 
              of adjustment), under the jacking points. It's then a simple matter 
              of checking that all jacking pads are aligned under the relevant 
              jacking points before operating the lift and raising the vehicle. 
              The ramp will lift a vehicle of up to 2 metric tonnes up to a maximum 
              of just over a metre in just over 50 seconds.
 
 Given the weight of the vehicle, and the fact that you are going 
              to be working underneath it, safety is a prime consideration. To 
              ensure the vehicle is safely supported when raised, the lift has 
              a series of stops or detents, which are essentially steel stops 
              which are welded to the bottom frame of the lift. As you raise the 
              vehicle, the lift 'clicks' past each detent in turn. Once you have 
              reached the desired height, it's a simple matter of lowering the 
              ramp slightly so that the lift locks firmly in place against the 
              steel stop. There's no need for any further support as the weight 
              of the vehicle is off the hydraulics, and the ramp is securely and 
              physically locked in place. To lower the vehicle, simply raise the 
              ramp slightly before 'capsizing' a catch on one of the supporting 
              arms. This lifts the arm sufficiently to pass over the metal stops 
              and lower the vehicle to the ground.
 
 So how 
              does the ramp work with an MGBGTV8 and RV8?
 I first tried it with my MGBGTV8 (a chrome bumper car, although 
              rubber bumper cars should be no different), and the lift worked 
              perfectly. The car had sufficient ground clearance to drive over 
              the ramp, and once swung into position, the pads located securely 
              under the spring pans on the front suspension, and under the rear 
              spring hangers just in front of the rear wheels. With the RV8 however, 
              it was a different story. Firstly, the lower ground clearance posed 
              a problem and I had to source two short planks of timber to place 
              alongside the ramp so that when I drove the car over the ramp, the 
              catalysts did not foul the ramps frame. Once in position however, 
              the supporting pads on the front jacking arms were again placed 
              under the spring supporting pans at the front, whilst the rear pads 
              fitted under the spring and torsion bar mounting brackets at the 
              rear. Although more of a fiddle with the RV8, the whole setup makes 
              the car far easier to work on compared to scrabbling around on the 
              ground under a car supported by axle stands.
 
 Extent 
              of the access
 Lastly, one of the most important issues when choosing a ramp or 
              lift is the extent of access to the underside of the vehicle when 
              up in the air. Of course a two-post lift with swinging arms is the 
              ultimate wheel-free lift which also gives access to the underside 
              of the vehicle for changing exhausts, gearbox etc. On my Autec model, 
              access to the underside of the vehicle whilst on the lift is of 
              course restricted by the frame of the lift itself. All is not lost 
              however, as Autec can supply extra long axle stands which, when 
              place under the vehicle, allow the ramp to be lowered (and even 
              removed) leaving the vehicle up in the air and with full access 
              to the underside.
 
 So in 
              conclusion, if you do all the maintenance work on your own cars 
              and have the space, a ramp is a very worthwhile investment. My next 
              step is to sink the ramp into a shallow pit in the floor of the 
              garage which will allow me to ensure the floor is clear when the 
              ramp is not in use. I've got the steel frame waiting for the pit 
              aperture - it's now just a question of getting digging!!!If 
              anyone has any further questions, I'm happy to answer them by email 
              (see the V8 Website for my contacts) or at Silverstone.
