Friction Coefficient
The friction coefficient represents the product's ability to resist load slippage when the load is
oriented in any position except horizontal. If the contact surface of either the load or the
vacuum pad is not clean, dry and in good condition, slippage is more likely to occur.
The Maximum Load Capacity (see SPECIFICATIONS) is based on a friction coefficient of 1.
However, the vacuum pad's ability to maintain this friction coefficient is reduced by factors such
as contamination, wear, age and exposure to sunlight, as well as the condition of the load's
contact surface. A pad that has surface contamination must be thoroughly cleaned (see Cleaning
discussion to follow). Over time, the rubber in a pad may experience hardening or leaching of
chemicals, resulting in stiffness or surface glaze. A pad that exhibits wear, stiffness or glaze
must be replaced.
In addition, every pad should be replaced on a regular basis, preferably after no more than 2
years, to ensure that the friction coefficient is not compromised. If necessary, contact your
dealer or Wood's Powr-Grip for more information.
