My thoughts were that the wooden top would distribute a lot of the load. As I said it was built for a much smaller tank...

I know this thread well, and understand what they say. Still I have what I have...maybe I will add wooden feet to the floor under the corners..

Actually I am just after peoples thoughts. Mild steel.. and I welded it. I have had a fish tank similar size in the same spot years ago, so the floor is OK. There is a wooden floor that goes in the bottom... No liability for anyone... just your thoughts and why.. I'm in NZ.. we do not sue...

Tank volume is 768l plus the tank and rock to go inside 2000m x 640mm wide x 600mm high Stand is made of 35mm square x 3mm wall thickness. Tank width is the same as the steel frame, notice the tank is not over the end legs. Wooden top is 50mm thick pined and glued planks... 4x top supports...

I all - thanks for the advice. I am looking at using an airbag. I have found quite a few that will fit perfectly, I will bolt the lifting frame to the air bag. I am pricing one from China -...

Thanks - Noted. Cheers!

HI Tom... good thing I have not purchased any cylinders yet, really appreciate your help. So larger cylinders could work? I just need to know what size I would need? Would pneumatic cylinders have enough power? Only wanting to raise and lower one end of the ramps. My 3.5 ton jack can lift both...

Righty Ho... here is another option using the cylinder to push. Remember this is upside down and it would be mounted to the underside of the ramp and there would be a wheel on the end of the arm which will push on the ground and lift the ramp.

Just to add - I only want to lift and lower the one end the the car drives on to, the front will pivot. Lift the rear end, remove 2 x supports, lower the rear end and back down and off the ramps. I do not think pneumatic would have enough power, worked with them for years, but if the hydraulic...

Hi Tom, Thanks for your reply, what if I turn the whole thing around so the cylinder is pushing to lift the car? I did not think about the reduction in force due to the area of the cylinder rod... assuming I am on track? I have no experience with hydraulic power. Hi Mike, with pneumatic...

I currently jack up the end of the ramps using the channel frame and a 3 1/2 ton jack, because of the height of the channel frame I have to have it sitting quite far back under the car for clearance when the ramp is lowered down to drive off. I have to push the jack a long way under the car to...
