Mini digger ramp






I need to rent a mini digger to deal with the remaining mess in the garden. There's a good ten tonnes of concrete foundation left from my guestimation, and it's covered in untillable clinker, hardcore and rubble, which all needs moving.

For ten minutes, I stood gimping around with the hinges on the uPVC door we've just had fitted, at a cost of £400 with the window and jamb. The digger is just small enough to get through, but it's too close for my liking with the door it' self in place. I was trying to take it off.

After all that, I found I could simply lift it off the pivots without doing anything, it's own weight hangs it. And those hinges are really nice! They have three adjustment screws on each of the three hinges that allow you to adjust the tilt and pan of the door by gently tweaking the hex fittings. Much better than normal internal doors that need both adjusting and fixing into place in the same operation.

I can't run the digger over the door jamb without it's 850kg fatness pulverizing the plastic. Instead, I found some reasonably straight 6x2 or close (probably thicker) aged timber in the garage and chopped it up on the mitre saw to create a ramp. Lots of glue screws and actual screws later, it's very sturdy. But the acid test is yet to come of coarse, it's too hard to predict how such heavy weights and high forces will behave until you've had some hands on experience with them.
