All,
I purchased the HF 2-Ton engine/shop crane to lift my new Grizzly G4003G lathe. After putting it together there is a gap between the base and the crane post. This gap is there because the spring bars in the back were too short. I researched this and read that it is done this way intentionally to "pre-load" the spring bars. Now, the gap is on the side facing the load, so that is better than in the rear I would think, but it still has me concerned. Is this crane safe like this? Will it settle after I put it under load? I have tightened the bolts pretty tight, I would say they are probably near 100 ft pounds.
This type of engineering is way outside my area of expertise.
I am attaching a photo for review. The gap is somewhere between 1/16" and 3/32" at the front, and it is flush in the back.
