LiftGuard Sling Protectors prevent damage to slings caused by contact with abrasive edges, corners, or protrusions from loads being lifted. They also keep the sling away from other significant contact points during lifting operations.
Overall Length: Equates to the total end to end length of a sling protector.
Safe Operating Zone: The useable area between the raised shoulders of the sling protector (see image below).
Width at Load: Sling Width Under Load.
o Sling Total Contact Width: Round synthetic slings compress and flatten as the load is picked. Select your sling protector based on the Sling Width Under Load.
o Caution – If your sling width under load is wider than the safe operating zone, the sling will point load. (see image below)
1” Sling Capacity: The maximum capacity per lineal inch of sling contact, ASSUMING the face of the sling protector (the portion in contact with the load) is in 100% contact on both the vertical and horizontal load surfaces.
Maximum Capacity: The total capacity of the individual sling protector, ASSUMING, the sling contact width does not exceed the safe operating area, AND the face of the sling protector is in 100% contact on both the vertical and horizontal surfaces.
What material does DICA use to manufacture LiftGuard Sling Protectors?
DICA’s patented LiftGuard units are made from a non-metallic, High-Performance Cast Nylon (HPCN). HPCN is chemically engineered to provide the high compression strengths needed to withstand the high pressures generated in the lifting industry. LiftGuard HPCN provides superior abrasion and wear resistance critical to both sling protection and load protection. In addition to its high strength and stiffness properties, LiftGuard HPCN is heat stabilized to allow for safe operations at higher temperatures.
Will the magnets on your sling protectors scratch finished or painted metal surfaces?
No, the magnets on all LiftGuard edge protectors are slightly recessed. This recess ensures a magnetic connection without direct contact that could scratch painted surfaces.
Will LiftGuard Sling Protectors float?
No, standard Lift Guard sling protectors will not float; they will sink. The specific gravity of the material is less than 1. Adding LiftGuard Velcro straps is a solution to help prevent the sling protectors from falling into the water in the first place.
What capacity do LiftGuard Sling Protector have when using ¾” wire rope?
The capacity of LiftGuard Sling Protectors is 12,500 psi/in of sling contact or 12,500 psi of compression capacity.
A ¾” diameter wire rope sling will have a contact area of less than 1”. This means the capacity of the sling protector will be less than 12,500 psi.
Capacity is calculated by multiplying 12,500 x the contact area of the sling. If the contact area of the wire rope sling is .5” then the resulting capacity would be 12,500 psi x .5 = 6.,250 psi.
The above direction is contingent upon having the vertical and horizontal edges of the sling protectors in 100% contact with the load, i.e., in full contact.
The above apply to all parts EXCEPT LiftGuard Groove Units. Groove unit capacity is calculated differently.
How do LiftGuard sling protectors hold up when used with a wire rope?
Wire Rope and Chain slings may damage Medium Duty sling protectors based on sling pressures and frequency of use.
LiftGuard Heavy Duty Sling Protectors are designed for use with all sling types but specifically designed for use when lifting heavy loads with wire rope, chain slings or frequent use of wire rope and chain slings.
When using wire rope or chain slings frequently or with higher loads, default to using Heavy Duty Sling Protectors.
Does Sling Angle Affect LiftGuard Sling Protector Performance?
Because LiftGuard Sling Protectors have a rounded surface, they are not affected by sling angle tension as long as the sling remains in full contact with the LiftGuard, and the horizontal and vertical surfaces of the LiftGuard remain in full contact with the load.
What is the Approved Operating Temperature for LiftGuard Edge Protectors?
The approved operating temperature is -20 to 220 degrees Fahrenheit.
