Coupler/Hitch
The coupler/hitch on most Ver-Mac PCMS units is a pintle hook and lunette ring combo. It
provides a more secure coupling than a ball-type trailer hitch, especially over rough surfaces
and on construction sites and is used in place of a ball coupler.
Some PCMS
units are fitted with an optional 2″ ball coupler.
8.1
Pintle Hook and Lunette Ring Combination
WARNING
Verify that the retaining pin for the pintle hook is properly locked
to avoid accidental release of the pintle hook and the trailer.
A 72 mm (3″ I.D.) round metal lunette ring is fixed horizontally on the trailer. The pintle
hook is a vertical ring that opens and has a jaw that attaches to a tow vehicle.
NOTE
Verify that pintle hook and draw bar on the tow vehicle have adequate capacity
for the trailer and all safety (or locking) cotter pins are in place and in good
condition.
8.2
Ball Coupler/Hitch
NOTE
This component is an option on Ver-Mac PCMS. Please check that your PCMS
has this component
before
proceeding.
CAUTION
Make sure that the trailer ball is completely engaged in the
coupler
.
When you attach the trailer to the tow vehicle, make sure it is hitched securely.
Use the trailer jacks to lower the coupler onto the ball
Make sure the coupler is in the loose position and that the clamp in the coupler
has dropped open
The trailer tongue should be snug on the ball when locked.
You have the proper adjustment when the coupler is as tight as possible on the ball
and you can still open and close the locking lever.
NOTE
If adjustment nut is too tight, handle does not lock.
