• Cracked, bent, worn, significantly corroded or improperly applied end connections.

Lifting Rope Replacement

Numerous factors are involved in determining when the lifting rope should be replaced. Once a

rope exhibits any of the following criteria, it should be removed from service and replaced with a
Wood’s Powr-Grip approved rope:
• Broken or cut strands.
• Core protrusion.
• Evidence of heat damage from any cause.
• Exposure to chemicals that may have caused the rope to degrade.

Care and Storage of Lifting Rope

Lifting rope may look like a simple, single part, but it is really a machine with many internal

moving parts, requiring as much care and maintenance as gears and chains. Rope should be
stored to prevent damage and deterioration. Place the Eazi Lifter in a dry location, and cover it
to prevent soil, water or other contaminants from damaging the rope.
When the rope is in use, care should be taken to prevent the ground or other objects from

scraping, nicking, or causing other damage to the rope. Also, the rope should never be dragged
on the ground, especially through dirt, mud or water.

The pulleys of the Eazi Lifter boom must be periodically inspected for damage, but otherwise

require very little maintenance. If at any time the pulley becomes cracked, chipped, dented or

otherwise damaged, replace it immediately. Operating with a damaged pulley puts it at risk of
failing or possibly causing a jam that cannot be cleared. A damaged pulley can also damage the
lifting rope, reducing its service life or requiring it to be replaced.

Friction Coefficient

The friction coefficient represents a hand cup's ability to resist load slippage when the load is

oriented in any position except horizontal. If the contact surfaces of either the load or the
vacuum pads are not clean, dry and in good condition, slippage is more likely to occur.
The Maximum Load Capacity of an Eazi Lifter equipped with Powr-Grip original N-Series hand

cups is based on a friction coefficient of 1. However, a vacuum pad's ability to maintain this
friction coefficient is reduced by factors such as contamination, wear, age and exposure to
