• 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
