12. ASSEMBLING THE LOAD BAR
The load bar is to be assembled in place, directly below the two (2) mat hoists.
Do not
attempt to assemble in another area and then “carry” into place. The load bar, when
assembled, is approximately 450 lbs.
Having appropriate protection for the floor in place, lay the center and two end portions
in line, with the flanges butting each other. Using the sixteen (16) 1/2” x 1-3/4” long
Grade 5 machine bolts provided, fasten together, utilizing lockwashers and hex nuts
(see
Figure M
).
13. CABLE ATTACHMENT TO THE LOAD BAR AND DRUM
For units hoisting one (1) mat only (45’ x 45’ maximum), the 5/16” cable is attached
directly to the load bar clamp (see
Figure M
). The 5/8” x 4” long Grade 8 bolts must be
used at this connection. The 5/16” cables must now be secured to each drum by
means of the cable block and two (2) 5/16”x 1-3/4” long machine bolts provided for
each drum. Note that the barrel end of the cable terminates at the drum, and must be
installed in-line with the drum rotation, ensuring the cable rotation does not wind (the
initial cable wrap) 180° against the barrel end.
For units hoisting more than one (1) mat, two (2) swivel pulleys are provided for
attachment to the load bar.
Do not substitute
the factory provided hardware.
Grade 8 bolts (and a nylock nut at the sheave) are shipped assembled. It is necessary
to disassemble the pulley, however, to route the cable down from the hoist, around the
sheave and back up to the frame assembly to be secured as shown in
Figure N
.
Secure the barrel end of the 5/16” cables to each drum, as described in the above
paragraph.
