M1022A1 Dolly Set…
hrow a shelter of PM over a shelter-carrying M1022A1 dolly set! Follow all the
info in your TMs, for sure, and then take note of these extra protectors.
Eyeball the cable harness
that attaches to the control
valve box on each of the
dolly set’s four lift cylinders.
Look for rubbed areas
where the harness sits next
to the tire. When the dolly is
folded, the harness can rub
against the tire, wearing
holes in the harness.
Ease off on sharp turns
when you’re backing a dolly
set with a 5-ton truck. The
dolly set turns shorter than the
truck when being backed, so
while your truck is still turn-
ing, the tie rods on the dolly
set are bending and breaking.
Then you dump whatever the
dolly set is carrying.

Worn through, the har-
ness shorts out during
operation of the dolly set.
Then the lift cylinder
won’t extend or retract.
If you see a rub, use
one or more tie straps,
to wrap the harness’s
cables together so they
stay away from the tire.
The dolly set’s tool box
looks like a convenient step
to use during checks and
services, but forget it.
Your weight will break the
mounting brackets that hold
the box in place on the dolly
set’s support frame. A busted
or missing tool box means
there’s no place to keep the
dolly set’s tools.
Cable Harness Rubbed Raw?
Stay Off Tool Box
Tight Turns Reminder
Use tie straps
