earckens Posted January 16, 2017 Report Share Posted January 16, 2017 Hi, for my TR4 maintenance I plan on installing a car "bridge" on which to lift the car to work underneath it. The bridge is detailed in the attachments. Is it ok to mount this car on this type of "bridge", by that I mean to rest it on 4 chassis points? Quote Link to post Share on other sites
boxofbits Posted January 16, 2017 Report Share Posted January 16, 2017 (edited) Hi I have put my TR4a on a similar lift with no problems. In fact there is plenty of strong chassis rail to support it on these cars. Regards Kevin Edited January 16, 2017 by boxofbits Quote Link to post Share on other sites
Paul J Posted January 16, 2017 Report Share Posted January 16, 2017 I have one of these for my 4A, works very well good strong chassis points for the rubber pads to locate. My only concern is that the suspension hangs unsupported so I don't leave it on for any long periods. Maybe ok but just my way of thinking. Paul Quote Link to post Share on other sites
earckens Posted January 16, 2017 Author Report Share Posted January 16, 2017 Thanks for the replies! I rest assured now. Erik Quote Link to post Share on other sites
Alec Pringle Posted January 16, 2017 Report Share Posted January 16, 2017 Hi Erik, the most important aspect is ensuring that the 2-post lift is sufficiently well secured to the garage floor - which implies 15 or 20cms of good quality concrete into which the base plates are bolted.

Motorsport Mickey Posted January 16, 2017 Report Share Posted January 16, 2017 (edited) Erik, Something to consider the 2 Post lifts are amongst the most "picky" as regards their fitment. The concrete base of the garage MUST be the correct quality as advised in the Lift fitting instructions, something like 3000lbs square inch with a minimum depth of 8" or 200mm, if you don't get this right the lift may be very dangerous in use and break away from the floor. Mick Richards Snap ! Alec was quick on the typing. Edited January 16, 2017 by Motorsport Mickey Quote Link to post Share on other sites
earckens Posted January 16, 2017 Author Report Share Posted January 16, 2017 Hi Mickey and Alec, thanks for that very important reminder! The garage is being built at the moment and luckily I was aware of this as the French contractor had provided 12cm of concrete floor thickness and I gave him in writing the instructions to provide an absolute minimum of 20cm thickness at any point within half a metre of the probable mounting place for the pillars, to use 350kg of cement per ton of concrete and a steel mesh concrete fortification for the whole floor. I originally had intended a pit but then the car wheels never would be freely accessible. I wanted to know if mounting a TR4 this way is doable before spending 2.500 euro on the bridge.

bookend69 Posted January 16, 2017 Report Share Posted January 16, 2017 Hi Erik I recently ordered a two post lift which should be delivered in about 8 weeks. I can't wait! My floor slab is of reinforced concrete, about 250mm thick, and 3000 lb/sq inch compressive strength. My garage has a roof height of 3.8 meters. I want to use the lift for both working on my cars, but also possible storage and have been warned that prolonged periods with the wheels off the ground can damage the suspension, particularly the shock absorbers. As it happens, this will not be of too much of a concern to me as I plan to completely strip and rebuild the suspension on my Rover. Once rebuilt however, I will have to devise a way of supporting the wheels. I've also read that the TRs should be ok on the 4 point (2 post) lift but take care on the positioning of the rubbers as it can result in flexing of the chassis. I haven't tried this yet, but will be doing so at some point I'm sure. Good luck Martyn Quote Link to post Share on other sites
Guest Posted January 19, 2017 Report Share Posted January 19, 2017 My favorite way of tinkering with the TR. Hanging suspension isn't a problem within reasonable time periods. Don't leave the suspension hanging for a winter when you 'store' the car like that. But a week or so is no problem. Good that you've decided against a 'pit'. I don't know anything about building regulations in other countries, but constructing a garage pit in Holland is more or less a 'NO!'. That has to do with fumes, gasses, electric sparks, ventilation etc. You can paint the picture. Perhaps over regulated, but in this case I can see the point of strict regulations.

clifish Posted January 19, 2017 Report Share Posted January 19, 2017 I much prefer the drive on 4 post lift that I have, no real worries about concrete, just get the sliding jack and you can easily get 1 axle off the ground to work on the suspension. It is also the only real way to stack/store the cars...that way you have room to get more for the collection. Quote Link to post Share on other sites

I want a bridge where the car is suspended on the chassis. And it would be for work only, so max a day in the air. Quote Link to post Share on other sites
Guest Posted January 19, 2017 Report Share Posted January 19, 2017 (edited) And it would be for work only, so max a day in the air. No problem then! A bridge is also the perfect machine for separating and joining the body and the chassis if you ever want to restore the car. Technically, you can put the body on the chassis without any help from friends - Saves you a lot of beer! About the pit... Well we're pretty good at controlling the water level. Although sometimes things get rough. But that's mostly after the winter when the snow melts and the rivers swell. And for me, well, I am on top of the hill... 12 meters above sea level! My feet stay dry. Thing is, when the ice caps melt, my house will be 100m from the new coastline according to Al Gore's stories! Drifting off topic here... only to mask my jealousy that you'll be able to put up a bridge in your garage and I am not. For one, the roof is too low.

badhuis Posted January 23, 2017 Report Share Posted January 23, 2017 The issue with this lift is that the wheels are not free. I want a bridge where the car is suspended on the chassis. I have an old s/h 4 poster lift, with a sliding jack as mentioned above. Whenever there is the need for free-hanging wheels I just put a beam on the jack, slide it under the car near the axle and suspend it on the chassis. Best of both worlds I think. I am never too sure about using a two poster lift, especially with flimsy cars or nose heavy cars (Citroën CX for example). Quote Link to post Share on other sites
