5.1 Under the Frame Sections [13 & 14] suspend by rope or chain, a 2x4 x 8 foot board as
shown in Fig. G
5.2 With the “Square Tube Section” of the Frame Weldment Assembly [12] still on the
ground, lift the “Drop V” Section of the Weldment Assembly [12] and place on top of
the 2x4 board and in position to (later) be bolted to the frame.
5.3 Using a come-a-long attached at the front pivots, draw the Side Channels [13 & 14]
together as you raise the “Square Tube Section” of the Weldment Assembly [12] into
the bolting position, and loosely attach the “Square Tube Section” [12] to the Side
Channels. Fasteners per side: (4 ea.) 1/2” x 1-1/2” bolt, nut lockwasher and
flatwasher on slotted holes.
5.4 Attach the “Drop V” Section of the Frame Weldment Assembly [12} to the Side

Step Procedure
Leveling the Hoist
6.1 Stand at the rear of the hoist and sight from the rear Cross Channel [11] to the front
Cross Channel to make sure the front and rear are parallel and that there is no twist or
warp in the hoist. If one corner appears to be low, place a block under that corner, as
necessary, to align the corners.
6.2 Stand at the side of the hoist and sight across the Side Channels [13 & 14] to make
sure that they are parallel and that there is no twist or warp in the hoist. If one corner
appears to be low, place a block under that corner, as necessary, to align the corners.
Tightening All
Fasteners
6.3 With the Unit Level Tighten all 1/2” bolts to approximately 65 ft.-lbs. of torque.
Exception: The 5” Hull Support bolts previously tightened. Note: When tightening
bolts on the frame, the end plates of the Cross Channels and Weldment Assembly
MUST be against the web of the side Channel - NO GAP should exist between the
parts.
