BTH-1 1..Available with other rubber compounds for special purposes (see www.wpg.com). 2..These dimensions reflect pad configurations with the Maximum Load Capacity; other configurations are possible for lighter loads. 3..The Maximum Load Capacity is rated at a vacuum of 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces with a friction coefficient of 1. Pad compound, load rigidity, strength, surface conditions, overhang, angle, center of gravity and temperature can also affect the lifting capacity. - Page 6 SPECIFICATIONS Note: Standard MRPTHD89AC (top) and MRPTHD1211LAC (bottom) are shown.

ASSEMBLY 2) Reposition telescoping pad arms and reposition or remove movable pad mounts as needed (see following sections): • To support the maximum load Route vacuum hoses as needed to prevent weight, you must install all damage to them during lifter operation. vacuum pads on the pad frame and connect all vacuum hoses to the pads (see following sections). -
Page 14: Extending/Retracting Telescoping Pad Arms
ASSEMBLY Extending/Retracting Telescoping Pad Arms Remove the cotterless hitch pin and slide a telescoping pad arm into or out of the pad frame until the hitch pin holes align at the desired position (fig. 1B). 2) Reinsert the pin to secure the telescoping pad arm (fig. 2B). 3) Repeat steps 1-2 to reposition other telescoping pad arms, as needed. -
Page 15: Connecting/Disconnecting Vacuum Hoses
ASSEMBLY Connecting/Disconnecting Vacuum Hoses Make sure quick connectors seal completely and all vacuum hoses function correctly (see “Vacuum Test” on page 27). To connect a vacuum hose, push the male and female ends of the quick connector together until they lock (fig. 1B). To disconnect a vacuum hose, move the release ring on the female end until the quick connector separates (fig. -
Page 16: 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 17: 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 1.0/2-21... -
Page 18: Operation
OPERATION EFORE SING THE IFTER Determine whether the vacuum lifter is capable of each intended task (see “SPECIFICATIONS” on page 3 and “INTENDED USE” on page 14). Then complete the following preparations: Taking Safety Precautions • Be trained in all industry Read all directions and safety rules before using and regulatory standards lifter. -

OPERATION ILT THE Make sure load is positioned correctly on lifter (as previously directed). 1) Make sure the load has enough clearance to tilt without contacting anyone or anything. Move the toggle switch on the movable control pendant up or down (fig. -
Page 25: 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. Push the vacuum release button ( — circled in fig. 1A) on the movable control pendant, to break the vacuum seal. Do not move lifter until pads release completely, because such movement could result in load damage or personal injury. -

Storing the Lifter Unplug the power cord (see “ASSEMBLY” on page 8). 2) Use the covers supplied to keep the vacuum pads clean (fig. 1A). !!–CE–!! To prevent the lifter from tipping over on relatively horizontal surfaces, use the parking stands as previously described, if the lifter has... -
Page 27: Inspections And Tests
2..The Periodic Inspection is also required whenever the lifter has been out of service for 1 year or more. Keep a written record of all Periodic Inspections. If necessary, return the lifter to WPG or an authorized dealer for repair (see “LIMITED WARRANTY”... -

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 29: Operational Tests
1..The load surface 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. -

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 31: Maintenance
MAINTENANCE Note: Refer to SERVICE MANUAL #35277 when applicable. ACUUM AINTENANCE Pad-to-Load Friction Coefficient The friction coefficient represents the lifter's ability to resist load slippage. The Maximum Load Capacity is based on a friction coefficient of 1, as determined by testing of clean, new, standard rubber vacuum pads on clean, dry, regular glass. -
