of wear, structural deformation, or cracks. Particular attention
should be paid to excessive wear at hoist hooking points and load
support areas. Brackets or straps showing any kind of wear in these
areas must not be used and should be discarded.
INSTALLATION
1. Position the lifting bracket assembly around the base of the
unit. Leave the top shipping skid on the unit to act as a
spreader bar. Be sure the strap does not twist.
2. Place each of the four (4) metal lifting brackets into the
rigging holds in the composite pan.
3. Tighten the ratchet strap unit tight. Lifting brackets should be
secure in the rigging holds.
4. Attach the clevis or hook of sufficient strength to hole in the
lifting bracket (See Fig. 6).
