Hydraulic Scissor Lift Repair/Refurb Assistance
Discussion
Hi all. Looking for some help please. When i bought my current house in 2013 there was a full height hydraulic scissor lift fitted in the garage.
As you can imagine this made me rather happy! That was until i went to use it for the first time and whilst it worked perfectly to get me car up in the air, once there it did not want to bring it down again… I managed to slowly release the pressure over a couple of hours to eventually get it back on the floor. I suspect that the valves that control the flow of oil are in need of replacement?
So i kind of forgot about using it as life always has other r priorities and i had no real need for it. Fast forward to today and I have just bought a ‘66 MGB and it would definitely now start to earn its space in the garage.
I suspect the rubber pipes between the control box and ramp could definitely do with being replaced. The lowering issue also needs addressing. I am based near Newmarket, does anyone have any recommendations for someone how could take a look with the idea to service and repair the ramps? Having had a look online a new similar set able to accommodate an MGB Roadster are approx £1,500 so service/repair willl need to come in cheaper than that.
I did have a google of local garage repair services but this didn’t throw anything up. I also called a couple of local firms that work with farm machinery as i assumed they would be familiar with pumps and hydraulics but they were not interested.

The coils on the left of the hydraulic unit picture will be there to control the oil flow. One or both of them will be the return to tank that allows the lift to lower. It looks like there is a label on the coil to show what voltage they run on. It's almost certainly one for up, one for down.
In the centre of the post the coil is mounted to you can see a small detent. On most valves of this type you can press this in to operate the valve if the coil fails (it physically moves the shuttle within the valve).
I would raise the ramp and press the detent in each valve to see if it works. The vast majority of the time it will, and your failure will be either the coil or its electrical supply. You can test to see if the coil is receiving power (test lamp or multimeter, depending on coil voltage). You can also power the coil directly to confirm it and the valve work.
Coils are very cheap, you just need to know the size of the hole through the centre and the voltage. Can you read any identifying marks on them?
