Page 9: Assembly
ASSEMBLY 1) Remove all shipping materials and save them with the shipping container for future use. 2) Suspend the lifter from appropriate hoisting equipment: 2.1) Select a crane and/or hoist rated for the Maximum Load Capacity plus the Lifter Weight. Note: Any lifter use must comply with all statutory or regulatory standards for hoisting equipment in your region. -
Page 10: Intended Use
2..A “single piece” of material includes curtainwall assemblies, unitized glazing systems and similar construction units. 3..Vacuum pads made from a heat-resistant rubber compound can enable you to lift loads with higher surface temperatures. Contact WPG or an authorized dealer for more information. -
Page 11: Operating Environment
1..Although lifter use may be possible at higher elevation, lifting capacity is reduced whenever the lifter is unable to attain vacuum in the green range on the vacuum gauge. Contact WPG for more information. 2..Special provisions may allow the lifter to operate outside the specified temperature range. Contact WPG for more information. Rev 5.1/4-21... -

OPERATION SE THE PTIONAL HUTOFFS Each pad shutoff on the pad frame controls the vacuum line to the adjacent vacuum pad. Activating or deactivating the airflow at specific pads enables the lifter to handle loads with different weights and dimensions (see “SPECIFICATIONS”) or to avoid holes in the load surface. To support the maximum load weight and larger load Closing any pad shutoff dimensions, all pads must be activated;... -

OPERATION IFT AND OVE THE Interpreting the Warning Light When vacuum is Never lift load unless warning devices turn off, because sufficient to lift the this could result in load release and personal injury. Maximum Load Capacity, the vacuum pump and the low vacuum warning light turn off temporarily, to conserve battery energy. -
Page 21: Controlling The Lifter And Load
OPERATION Controlling the Lifter and Load When the lifter is ready, use the hoisting equipment to raise the lifter and load as needed. Use the control handle (circled in fig. 1A) to keep the lifter and load in the required position. Once there is enough clearance, you may move the load as required. -
Page 22: T O Release The Pads From The Load
OPERATION ELEASE THE ADS FROM THE Make sure load is at rest and fully supported before releasing vacuum pads. Place the vacuum control valve lever in the “release” position ( — fig. 1A), to break the vacuum seal. Do not move lifter until pads release completely, because such movement could result in load damage or personal injury. -
Page 23: Storing The Lifter
OPERATION Caution: Do not set the lifter on surfaces that could soil or damage vacuum pads. Note: The adjustable control handles (fig. 2C) can be used to support an unloaded lifter when not suspended (see “T ”). DJUST THE ONTROL ANDLES Storing the Lifter Use the covers supplied to keep the vacuum pads clean (fig. -

12" Hg [-41 kPa] for 5 minutes. If not, lifting this load requires additional precautions (eg, a load sling). Contact WPG for more information. 8) Lower the load after 5 minutes or before the vacuum level diminishes to 12" Hg [-41 kPa]. -
Page 26: Operational Tests
1..The load should have either a flat surface or no more curvature than the lifter is designed for, if any. 2..For more information, search for your lifter’s Model Number at www.wpg.com and select the “Troubleshooting” link on the product page. -
Page 27: Rated Load Test
7) Prepare a written report of the test and keep it on file. 1..An equivalent simulation may also be used. Contact WPG for more information. 2..A “qualified person” has successfully demonstrated the ability to solve problems relating to the subject matter and work, either by possessing a recognized degree in an applicable field or a certificate of professional standing, or by possessing extensive knowledge, training and experience. -
Page 28: Maintenance
MAINTENANCE Note: Refer to SERVICE MANUAL #36114 when applicable. ACUUM AINTENANCE The Maximum Load Capacity is determined by testing of clean, new, standard rubber vacuum pads on clean, dry, regular glass. If the lifter is used under any other conditions, a qualified person must first determine the effective lifting capacity. -
Page 29: Pad Cleaning
4) Allow each pad to dry completely before using the lifter. 1..A brush with bristles that do not harm rubber can help remove contaminates clinging to sealing edges. If these cleaning methods are not successful, contact WPG or an authorized dealer for assistance. Rev 5.1/4-21... -
