QUADRA-TILT ROTATOR • DC-VOLTAGE

Conversely, allowable thickness increases as load weight decreases.  In addition, an operator 

may be able to manually counteract the tendency of unstable loads to tilt out of the upright 

position, provided that the operator maintains control of the load at all times (see

necessary, contact Wood’s Powr-Grip for help in determining the maximum thickness 
permitted when handling any specific load. 

Note:  Vacuum pads can stain or deform load surfaces with light colors or soft coatings.  The 

operator should test such surfaces for detrimental effects before using the lifter on them.

The operator must determine whether the lifter is intended to be used in each work environment, 

in accordance with the following restrictions: 

WARNING:  Never use lifter in dangerous environments. 

• This lifter is not intended for use in any environment that is inherently dangerous to the 

operator or likely to compromise the lifter's ability to function.  Environments containing 
explosives, caustic chemicals and other dangerous substances must be avoided when using 

the lifter. 

• The lifter's work environment is limited by the Operating Elevation and Operating Temperatures 

indicated in SPECIFICATIONS. 

• Using the lifter in wet environments may require the operator to take special precautions: 

Moisture on contact surfaces of the load or vacuum pads diminishes the lifter’s slip resistance, 

thereby reducing the lifting capacity (see MAINTENANCE: V

ACUUM 

P

AD 

M

AINTENANCE

: Friction 

Coefficient). 

WARNING:  Moisture reduces slip resistance of vacuum pads. 

Although the lifter's exterior surfaces can tolerate some exposure to water vapor, they are not 

designed to be water-tight.  Submerging the lifter or using it in rain may damage lifter 

components; these and similar conditions must be avoided.
