Rigging Equipment for Material Handling Your Safety is the #1 Priority
This program is to be used to ensure a safe working environment during lifting operations utilizing slings and other rigging equipment.
This program applies to slings and rigging equipment used in conjunction with jib cranes, overhead shop hoists, boom trucks, truck hoists, and etc. to move heavy parts and equipment whether the lift is performed in the shop or field.
This program does provide information on Alloy Steel Chain Slings, Wire Rope Slings, Metal Mesh Slings and Synthetic Slings.
There are no specific training requirements for slings, but awareness level training is incorporated with rigging equipment for material handling.
Inspections of slings for damages or defects is done by a competent person, but the re-certification of repaired or reconditioned slings must be done by a qualified vendor.

2. Safe working load Recommended safe load

Mark custom lifting accessories
Proof test to 125 percent
Do not load rigging equipment in excess of its recommended safe working load.
Special custom design lifting equipment shall be marked to indicate the safe working loads and shall be proof tested (by a qualified vendor) to 125% of their rated loads, prior to use.
No homemade lifting devices shall be used unless it has been proof tested (to 125%) by a qualified vendor.
Do you have any special “spreader bars” that was built in your local shop to lift parts, equipment or engines that are common to the region – has it been certified?

3. Rigging Equipment Define Rigging Hooks Shackles Eyebolts 4/14/2017
Rigging refers to the hardware and equipment used to safely attach a load to a lifting device.
Hooks shall be removed from service when the hook is opened more than 15% at the throat.
Hooks shall be removed when it is bent more than 10 degrees from the plane of the unbent hook.
Ensure shackles and eyebolts are installed in accordance with the manufacturer’s recommendations.
Ensure shoulderless eyebolts are threaded in at least 1.5 times the bolt’s diameter.

16. 4/14/2017
Rigging
Rigging a load
Determine the weight of the load - do not guess.
Determine the proper size for slings and components.
Do not use manila rope for rigging.
Ensure that shackle pins and shouldered eyebolts are installed in accordance with the manufacturer's recommendations.
Ensure that ordinary (shoulderless) eyebolts are threaded in at least 1.5 times the bolt diameter.
Use safety hoist rings (swivel eyes) as a preferred substitute for eye bolts wherever possible.
Pad sharp edges to protect slings.
·  Remember that machinery foundations or angle-iron edges may not feel sharp to the touch but could cut into rigging when under several tons of load.
·        Wood, tire rubber, or other pliable materials may be suitable for padding.

17. Rigging
Do not use slings, eyebolts, shackles, or hooks that have been cut, welded, or brazed.
Install wire-rope clips with the base only on the live end and the U-bolt only on the dead end.
Determine the center of gravity and balance the load before moving it.
Initially lift the load only a few inches to test the rigging and balance.
