Again, thanks! | | | | Joined: May 2013 Posts: 51 Wrench Fetcher | | Wrench Fetcher Joined: May 2013 Posts: 51 | Looking for ideas for working under the dump bed of my truck and want the safety of not being squished like a bug. So my question is what do you guys use for locking the bed in the up position? I need to do body work on the back of cab. Any suggestions much appreciated. Thanks Jon

On his dump truck (80's model GM- I don't know specifics) there is a bracket made to insert a post(?) somewhat like a engine hood support. I don't guess we ever had the post, and we weren't ever under the thing for bodywork...
I'd use 2- 6"x6" posts on end as a brace. Find a good attachment point on the truck frame & the bed frame to tie off or bolt through. Stack up a bunch of tires. Or, use a steel gantry crane (minus the casters) assembled in place. I'm just throwing out some ideas- you could even frame a 2"x4" structure under there (think "lean-to") if you think the bed will be raised for quite a while. Edit- Even if there is a designed/functional/factory way to lock the bed in the upright position, I'd still build something else if I was going to be under it.
Brad Wrench Fetcher, PhD | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy JH51, I would use at least one piece of 4 X 4 wood located between the chassis and dump box in the up position. Position the support on a chassis crossmember or frame rail and against a substantial part of the underside of the dump box. You should come up with a method of holding the brace in place, something other than the weight of the dump box resting on the support, that way it can't be accidentally knocked out of place. If you have a substantial piece of steel you could tack weld it in place also. More than one piece of wood or steel would be better, try to position the brace(s) so they are not in your way while working. Good luck, be safe. | | | | | Joined: May 2013 Posts: 51 Wrench Fetcher | | Wrench Fetcher Joined: May 2013 Posts: 51 | Thank you Brad and 3b. 6x6's and a gantry crane sounds pretty good and maybe some welded braces can't be to careful right. Thanks again

Years ago most dumps had to raise the bed to fill gas. We kept drive shafts for the guys to use for a safety while filling gas. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | Please, please, please be EXTRA careful.

Clamp the pipe over the hydraulic ram for the bed lift cylinder so it cannot retract. I did a lot of maintenance on dump trucks when I worked for a concrete company and we had a custom-fitted ram lock for every truck in the company. Our ram locks were made out of schedule 80 steam pipe and had hinges and welded-on flanges for several bolts to hold them clamped over the ram. Jerry

Otherwise, do as 3B suggested. Jerry's method also seems like a good idea. Whatever you do, be careful and be safe. As Alvin mentioned, I also knew a guy who was killed by one. | | | | | Joined: Jul 2008 Posts: 326 'Bolter | | 'Bolter Joined: Jul 2008 Posts: 326 | x2 on Jerry's idea. But you will need the 4x4 or 6x6 during fabrication of the ram lock. Take a look at these folks to get some other fabrication ideas. http://dump-lok.com/Be extra careful.

Definitely going to use most all of them expecially Jerry's ram lock. Safety is number one and most important to me.
