I bought an Autovip car tilter at the end of last year as I had a job to do that really needed the car on it's side or upside down. A rotisserie would have been my prefered choice but a lack of garage length would have made walking around the car difficult and this Autovip 1700 came up at the right price unused. As I need to tilt the car on both sides more than once per side, this would require unbolting the mounting brackets from the hubs and refitting the wheels to push the car outside and turn it round. This would be very time consuming and I would need someone to help push so I decided to make an adjustable chassis dolly that would attach to the Autovip hub brackets. Luckily I had been given some 450kg capacity braked castors as used on scaffold towers that might come in handy one day so I designed the dolly around those using 48.3mm diameter 3mm wall steel tube for the uprights that drop into the castors. The main dolly frame is 50 x 50 x 3mm box section with 100 x 8mm plate cut to 200mm long for the clamping plates. These are drilled for 4 off M10 bolts to give plenty of adjustment catering for any vehicle that will fit the Autovip frame and the whole assembly can be easily disassembled for storage. The Autovip frame is held together by six 10mm pins retained with R clips and once removed four of these go through the chassis dolly uprights then the frame is assembled under the car. The frame is very rigid once clamped together and moves relatively easily for an oversized shopping trolley! I can now move the car outside on my own and turning it round is easily achieved by locking a brake on an individual castor. I have just enough room to roll the car fully in my garage, a 1966 Jensen CV8. Adjustable for any vehicle that will fit on the Autovip frame, large...... ......or small! Uprights drop into the castors, clamp plate welded to upright. Lower plate has full weld to box section. Each castor braked. Outside for the first time in a while.
