a. General. Bolster trucks covered in this manual are designed to transport utility poles and
bridging sections weighing up to 20,000 pounds over highway, or 10,000 pounds cross-country.
They are equipped with a cab protector, front and midships winches, and a bolster trailer. The
bolster trailer is transported on the bolster truck carrier top when not in use.
Never disengage the power takeoff (6) when
the transfer (7) is in NEUTRAL. This will
disengage the power takeoff pump, and the
resulting lack of lubrication can cause
transfer bearing failure.
b. Untoading P-14 Trailer From Truck.
(1) Position bolster truck on a level surface, apply handbrake (8), and stop the engine.
(2) Release and remove chain binder (10) at rear of trailer. Remove tiedown chain(13)
from lifting shackles (9) on trailer and towing shackles (11) on truck.
(3) Hold ring (16) on L-bolt (15)
while turning handle (17) to loosen L-bolt.
After L-bolt is loose, turn bolt until it drops
through slots in ramps. Repeat procedure on
opposite side. Remove ramps (14) from
catwalk and install in mounting brackets
(12) attached to rear support of bolster
carrier. Set L-bolts aside.
