Safety First - So I don't kill myself or somebody else...
I am new to the M936, but reading the TM seems like the right thing to do. TM 9-2320-272-10 (Pages 2-136 to 2-140) show and explain the use of Shipper Braces that provide boom stability on the road. The TM also explains those other two arms for the boom (called Boom Jacks) that attach to boom then sit on the ground for heavy lifting.
In a "past life" I worked for a company called RH Bouligny. They were a steel high-line contractor (now defunct) that used primarily WWII era IHC's, Deuces, 5-Tons, Dodge Weapons Carriers and M4's. All were heavily modified for working where nobody else wanted to go. In the swamps and in the Virginia hills. I loved that job. Anyway, as the years went by I went from being a wrench turner to a hydraulic mechanic.
Earlier today, I raised the boom on my M936. Max up with Max extension on the Crowd Boom. The great news is that there was no "popping" sound as it sat there. No obvious leaks - although I can't imagine why because the deck is pretty nasty. The boom sat like that for about 4 hours. I was preparing to stow the boom and decided to climb up and press the far left lever (boom control) forward to verify that the check valves were functioning correctly. It should not have moved - but it did. This boom does not appear to have check-valves?
Everything we used had "CHECK VALVES" in the lines where a boom was in the air. Where a catastrophic hydraulic line failure would cause the boom to come crashing to the ground. Again, this truck does not appear to have that safety feature. Is that normal?
Picture below shows the M936 lifting without the Shipper Braces. It is a rotator. If they hadn't intended it to be able to pick and swing - the Shipper Braces would have been attached permanently - right? One of the uses for this truck is to remove and replace a 5000# rocket pod from a MRLS. Pick from behind, rotate to the side, drop on the new pod... Rotate being the key.
Just thinking out loud here, but I would think dropping that - if a hydraulic hose busted would cause a really bad day.
