Alloy steel end fittings are zinc plated. Mesh is 10 gage galvanized high tensile steel (12 gage upon request).

Optional: Type 304 stainless steel mesh is availablefor use in corrosive environments.

HOW TO ORDER WIRE MESH SLINGS


*		Do not edge load. Full width of mesh must contact load.

Under normal usage, wire mesh slings will
eventually need repairs. We can perform this
service and re-certify all sling brands at a relatively
low cost. Wire mesh slings that are repaired are
guaranteed to meet or exceed original specifications.
Five Lift-All factories are strategically located in the
U.S. to ensure prompt service. Wire mesh slings
should be removed from service and/or repaired
under the following conditions:

• A broken weld or brazed joint along the sling edge.
• A broken wire in any part of the mesh.
• Reduction in wire diameter of 25% due to
abrasion or 15% due to corrosion.
• Lack of flexibility due to distortion of the mesh.
• Visible distortion or wear of either end fitting.
• Cracked end fitting.

NOTE: The choker fitting must be positioned against a
load edge or directly on the triangle fitting.

INSPECTION CRITERIA FOR WIRE MESH SLINGS

The following photos illustrate typical damage that occurs, indicating that the sling must be removed from service. Please review the Safety Bulletin provided with each sling.

THE DAMAGE: OVERLOAD / UNEVEN LOADING WHAT TO LOOK FOR: Mesh does not lie flat, appears distorted and/or will not bend easily. TO PREVENT: Do not load in excess of rated capacity. Load edges must be straight / flat and in contact with full width of mesh at bearing points.

	THE DAMAGE: Wear WHAT TO LOOK FOR: Flat areas on the individual wires. When wires have lost 25% or more of their original diameter, the sling must be taken out of service. TO PREVENT: Do not drag sling on the ground and do not drag loads over slings. Pad high wear areas.


THE DAMAGE: CORROSION / HEAT DAMAGE WHAT TO LOOK FOR: Areas of discoloration. Remove slings with wire diameter reduction of 15% or more. Slings exposed to temperatures of 550° F or more must be removed from service. TO PREVENT: Hang slings for storage away from moisture. Do not use mesh slings above 550° F. Consider using stainless steel mesh.


		THE DAMAGE: BROKEN WELD OR BRAISED JOINT WHAT TO LOOK FOR: A cracked or separation of the wire at the edge or in the body of the mesh. TO PREVENT: Do not side load mesh. Tension on sling must be distributed evenly across the entire width of the mesh.


THE DAMAGE: DISTORTION OR WEAR OF END FITTINGS WHAT TO LOOK FOR: Fittings that do not lie flat or have obvious areas of wear. TO PREVENT: Never lift with fitting against a load edge or set load directly onto sling. Reduce wear by keeping loads within the rated capacity of the sling.



EFFECT OF SLING ANGLE

Using slings at an angle can become deadly if that angle is not taken into consideration when selecting the sling to be used. The tension on each leg of the sling is increased as the angle of lift, from horizontal, decreases. It is most desirable for a sling to have a larger angle of lift, approaching 90°. Lifts with angles of less than 30° from horizontal are not recommended. If you can measure the angle of lift or the length and height of the sling as rigged, you can determine the properly rated sling for your lift. The Increased Tension method provides the increased tension as a function of the sling angle. Alternatively, the sling Reduced Capacity method may be used to determine reduced lift capacity for any angle.

INCREASED TENSION Determine capacity of sling needed		REDUCED CAPACITY Calculate rating of each sling rigged at this angle

1. Determine the load weight (LW).		1. Calculate the reduction factor (RF).
			a. Using the angle from horizontal, read across the Angle Chart to the corresponding number of the Reduction Factor column.
2. Calculate the Tension Factor [TF].
	a. Determine the sling angle as mea- sured from the horizontal, and the corresponding tension factor (TF) from the effect of angle chart.
			-OR-
			b. Divide sling height* (H) by sling length* (L).
	-OR-
	b. Length* (L) divided by height* (H)

		2. Reduction factor (RF) x the sling’s rated capacity for the type hitch that will be used = sling’s reduced rating.


3. Determine the share of the load applied to each sling leg (LW).


4. Multiply (LW) by (TF) to determine the sling leg tension. The capacity of the selected sling or sling leg must meet the calculated tension value.		*Measured from a common horizontal plane to the hoisting hook.


*Measured from a common horizontal plane to the hoisting hook.

Tension Factor (TF)	Angle From Horizontal	Reduction Factor (RF)
1.000	90º	1.000
1.004	85º	0.996
1.015	80º	0.985
1.035	75º	0.966
1.064	70º	0.940
1.104	65º	0.906
1.155	60º	0.866

1.555	40º	0.643
1.742	35º	0.574
2.000	30º	0.500

Example:

Vertical Choker rating of each sling:
6,000 lbs.
Measured Length (L) = 6 ft.
Measured Height (H) = 4 ft.
Reduction Factor (RF) = 4 (H) ÷ 6 (L) = .667

Example:

Load weight = 1,000 lbs.
Rigging - 2 slings in vertical hitch
Lifting Weight (LW) per sling = 500 lbs.
Measured Length (L) = 10 ft.
Measured Height (H) = 5 ft.
Tension Factor (TF) = 10 (L) ÷ 5 (H) = 2.0
Minimum Vertical Rated Capacity required
for this lift = 500 (LW) x 2.0 (TF) = 1000 lbs.
per sling

Sling capacity decreases as the angle
from horizontal decreases. Sling angles
of less than 30° are not recommended.

Reduced sling rating in this configuration
= .667

(RF) x 6,000 lbs. = 4,000 lbs. of lifting
capacity per sling
