Chocks

[tbearatkin]

Somewhere at a location overseas about the year 1987. The conversation in the office must have went something like this: "Petty Officer Brunelle, why do you need a wrecker at the Test Cell this morning? You had your crew doing what in the dark while it was pouring rain? Do you know what wheel chocks are?"


What do you mean the parking brakes don't work on these 5 tons?

Looks like Ron was driving it.

I watched a Marine M818 roll down a hill at a very small camp in El Salvador some years ago. As it rolled from the motor park down hill into the ditch that bisected the camp, the Marine jumped from the cab. From my perspective it looked like he **** near rolled into the path of the truck right before it crashed into the ditch. Chock blocks are indeed critical items.

The person that did this said his boot did not stop it either, nor did the yellow tape they made us put around our projects to stop things from entering the area.
I can see the problem from here, The asphalt gave out around the front of this perfectly parked 5 ton. No SeaBee I know would ever let this happen? HAAAAAAA Who the **** am I kidding.

I'll bet this poor Bee had to wear the wheel chocks around his neck for a week.

Not really, I drove (flew)the 819 out of the ditch, did a field repair or 2, then DROVE it to the maintenance yard 1 1/2 mile away, where it waited transport to its home LZ for permanent repairs, sure was not like someone I knew who laid his truck on its side and required a LOT of help just to get wheels DOWN.

I'm still in and I can see the purpose for them on the older air over hydraulic trucks and the HMMWV's but we still have to use them on straight air trucks with spring brakes such as LMTV's, Hemmt's, LHS's, PLS's and such. As long as you pull the parking brake diamond out, it's not going anywhere. Forget to pull that out, once it leaks down to 60 psi, it's popping out on it's own. Chock blocks on current trucks are overkill but for the older stuff we roll in, not a bad idea.

When I first saw the title of this thread, I thought it was about cucvs, and since cucvs are not very high on the important list, did not read it the first or second time around.

I keep my parking brake nice and tight but I use clocks too just in case. At the storage lot the parking area slopes back a little so I back the deuce up against a nice thick railroad tie. I then apply the parking brake and chocks.

OOPS!

OK that comment got me subscribed.

This one ought to end up pretty humorous.

OK. Subscribed.

In Crash Crew, we keep a crash truck with full crew on the runway during all flight ops (hotspot). They can be on an aircraft in seconds when there is trouble. We were on an operation one time, and a 2ndLt walks up to one of my crash trucks at hotspot. He asks the crew chief why he does not have the truck chocked? My young Marine could only say "really?Sir?

Where do you put your chocks? I put 2 behind the driver side rear wheels (middle axle and rear axle). It rests on a small incline.

When you're not on an incline where do you put them?


After looking at the video below I should put 2 behind my rear right and left tires.

Those tires looked under-inflated:

- wonder if that monster rig might have rolled over those chocks if the tires were at full pressure?

Not sure, would that make a difference?

I would think a truck under power would be able to negotiate the chocks without incident?.

Yep, a certain 819 has been known to drive over forgotten 6x6 blocks at times.
