Compact A2B with Stowage Cut-out, Install/Adjustment Instructions
The purpose of the Stowage Cut-out system is to prevent a situation
whereby the wire rope is over-tensioned when the load block / wire rope is attached to the stowage hook on the bottom of the primary boom assembly.
However, the OPERATOR is ultimately responsible for ensuring that the
wire rope is not over-tensioned when stowing the wire rope and boom
assembly into the boom rest.

CAM LOBE
1.
Initially, apply a light torque to the nyloc full nut (Item #1), such that the
axle bolt & cam welded assembly can be rotated / adjusted in the steps below.
2.
Position the cam
lobe
(Item #2)
so that it is pointing towards the housing
/ mechanism
3.
Hang the load block on the open stowage hook under the primary boom.
4.
Thread the wire rope through the load block in a two-line configuration; the wire rope end / eyelet is pinned in the standard position on the tertiary boom tip
5.
Actuate the Winch Up function until the load block and wire rope are
taut
enough to prevent the load block from bouncing during transit,
but do
not tighten excessively so as to prevent damage to the wire rope.
6.
Rotate the axle bolt & cam welded assembly towards the housing
(clockwise in standard configuration) until the cam lobe makes contact
with and trips the wobble micro switch and actuates the A2B function.
7.
Once adjusted, torque the nyloc full nut (Item #1) to 100 ft*lbs to prevent
further rotational movement of the axle bolt & cam welded assembly.
8.
Test the A2B trip-point by slackening and tightening the wire rope / load block assembly (Winch Up/Down); the point at which the A2B trips should be consistent and repeatable in terms of wire rope tension when stowed.
