Fig. 7 – Rigging Weights

Step 4 – Rig and Place Unit

Rigging  and  handling  of  this  equipment  can  be  hazardous  for  many

reasons due to the installation location (roofs, elevated structures, etc.).
Only trained, qualified crane operators and ground support staff should

handle and install this equipment.
When working with this equipment, observe precautions in the literature,

on  tags,  stickers,  and  labels  attached  to  the  equipment,  and any other

safety precautions that might apply.
Training for operators of the lifting equipment should include, but not be

limited to, the following:

1. Application of the lifter to the load, and adjustment of the lifts to

adapt to various sizes or kinds of loads.

2. Instruction in any special operation or precaution.
3. Condition of the load as it relates to operation of the lifting kit, such

as balance, temperature, etc.

Follow all applicable safety codes. Wear safety shoes and work gloves.

Inspection

Prior to initial use, and at monthly intervals, all rigging shackles, clevis

pins, and straps should be visually inspected for any damage, evidence

of wear, structural deformation, or cracks. Particular attention should be

paid to excessive wear at hoist hooking points and load support areas.

Materials showing any kind of wear in these areas must not be used and

should be discarded.

1. Leave  top  shipping  skid  on  the  unit  for  use  as  a  spreader  bar  to

prevent the rigging straps from damaging the unit. If the skid is not

available, use a spreader bar of sufficient length to protect the unit

from damage.
