  • dump body floor

    Started this late yesterday. Floor was hammered, rotted & patched. I cut out the flat part, added a few cross member sections where it was smashed down, now I'll weld in a new floor. It will follow the bend up the side about 2" above where the 45* pc. meets the side.

    One flat sheet centered & then I bent up two side pcs. The reason for doing it this way is handling the side pcs. while bending is easier as there is no crane or fork truck access to the brake I use. It requires an extra seam but the easier handling makes up for it.

    Looks like quite a job. Did you use a plasma cutter to remove the floor?

        I have a C65 I carry 13000 in a 14' dump box, sometimes boulders. I'm pretty careful setting them in but it can get rough dumping them. Oak 2-1/4" floor held up OK about seven years, now it's rotten. I have considered yellow pine pressure treated or steel. Cross members are about 16" apart Could steel work better? How thick, would it be lighter than 200 lb planks 10" wide? Should I add cross members for steel?

          I would not use pine or pressure treated as it won't hold up. If going wood replacing the oak with oak would be best.

          If you went steel 1/4" plate is 10.2# sq. ft. 3/16" plate is 7.15# sq. ft. Load will slide out better with steel. You could always add a few extra cross members while the floor is out.

            Finally got to finish this up. Ran out of time on Monday. Left the floor long in the back & then cut to fit it to the gate. No bigger gap than 1/8" now. First pic is from the other day.
