HF GANTRY CRANE MODIFIED FOR ROUGH/ UNEVEN TERRAIN

[IntheGroove]

My work area is dirt or ice depending on the season. I modified my HF gantry crane to work in these conditions.

First I replaced the four inch steel casters for eight inch rubber casters. Then I added six inch extensions to the four corners and mounted four trailer jacks. Four spirit levels were attached to the posts so it can be made plumb, level and square.

I have since replaced the original 4.5 inch I beam with a 15 foot long 6 inch I beam so when not in use it straddles my carport...
