TOCHANGE THE PAD FRAME CONFIGURATION
ASSEMBLY

MRTALPCH6-DC3(RC): #35125 Rev 1.0/12-1910
Two pad frame configurations enable the lifter to match different load dimensions and weights.
The illustrations on the preceding page show both approved configurations. Pad Spread and
Maximum Load Capacities are listed for a standard MRTALPCH611LDC3 lifter (see
“SPECIFICATIONS” on page 3 for other models).
Use only these pad
frame configurations.
Caution: Connect the vacuum pads to the circuits of the dual vacuum system, marked “1” and
“2” in the preceding illustrations (see “Routing Vacuum Hoses” on page 11 and “Connecting/
Disconnecting Vacuum Hoses” on page 12).
Choose a configuration to maximize support across the load
surface and to minimize load overhang (see “LOAD
CHARACTERISTICS” on page 13):
• To support the maximum load weight and longer dimensions, both pad frame extensions
must be installed on the pad frame and the vacuum hoses for the corresponding vacuum
pads must be connected, using the quick connectors (see “Routing Vacuum Hoses” on
page 11).
•
Removing or disconnecting any
vacuum pad reduces lifting capacity.
Either install both extensions or
remove both to keep lifter balanced.
To support smaller weights and
dimensions, both pad frame extensions
may be removed, and the
corresponding vacuum hoses may be
disconnected, provided the lifter still
has sufficient capacity to support the
load in question.1
Installing/Removing Pad Frame Extensions
1) Set the lifter with the vacuum pads facing downward on a clean, smooth, flat surface.
2)
2A 2B
Insert the tabs on one pad frame
extension between the rails of
the pad frame (figs. 2A-B).
Note: The pad frame extension
with a control handle should be
installed on the lower end of the
pad frame when oriented
vertically (see relevant illustration under “SPECIFICATIONS” on page 4).
1..... Whenever a quick connector is disconnected, the corresponding vacuum pad does not contribute to the lifting capacity, whether or not the pad
is mounted on the pad frame.
ASSEMBLY

3A 4A 4B
Rev 1.0/12-19 MRTALPCH6-DC3(RC): #3512511
3) Align the bolt holes in the pad frame extension with those in the pad frame (fig. 3A).
4) Secure the pad frame extension in the pad frame by installing and tightening all bolts
securely (figs. 4A-B).
5) Connect the vacuum hose to the vacuum pad on the pad frame extension (see “Routing
Vacuum Hoses” on page 11 and “Connecting/Disconnecting Vacuum Hoses” on page 12).
6) Repeat steps 2-5 to install the other pad frame extension.
7)
7A
Reverse steps 2-6 To remove pad frame extensions.1Store
removed extensions in a clean, dry location. Use the pad covers
supplied (fig. 7A) to keep the vacuum pads clean.
Routing Vacuum Hoses
Each of the 2 pad frame configurations requires different vacuum hose routing; see labels on
blue hoses for assistance.
For the
1A
6-pad configuration (fig. 1A):
1) Connect the red hose (R) from the vacuum
pad on a pad frame extension as shown.
2) Connect the blue hose (B) as shown.
3) Repeat steps 1-2 for the other frame
extension
1..... The pad frame extensions do not need to be removed when using the 4-pad configuration unless they would inhibit (or otherwise compromise
safety of) loading, positioning a load or releasing a load.
ASSEMBLY

MRTALPCH6-DC3(RC): #35125 Rev 1.0/12-1912
For the
2A
4-pad configuration (fig. 2A):
Do not connect hoses from pad frame
extensions in 4-pad configuration.
1) Make sure the red hose (R) from the
vacuum pad on a pad frame extension is
disconnected as shown.
2) Connect the blue hose (B) as shown.
3) Repeat steps 1-2 for the other frame
extension.
3A
The 2 vacuum circuits correspond with their matching vacuum gauges
(fig. 3A).
Make sure quick connectors
seal completely and all
vacuum hoses function correctly
(see “Vacuum Test” on page 32).
Note: The gauge face colors do not correspond with the circuit colors.

INTENDED USE
LOAD CHARACTERISTICS
Do NOT lift explosives, radioactive
substances or other hazardous materials.
Make sure the vacuum lifter is intended
to handle each load according to these
requirements:
• The load weight must not exceed the Maximum Load Capacity.
• The load must be a single piece of relatively nonporous material with a flat and
relatively smooth contact surface.1, 2To determine whether the load is too porous or
rough, perform the “Lifter/Load Compatibility Test” on page 31.
• The load's contact surface must be able to obtain a friction coefficient of 1 with the
lifter's vacuum pads (see “Pad-to-Load Friction Coefficient” on page 34). Otherwise, the
capacity should be derated appropriately.
• The load's surface temperature must not exceed the Operating Temperatures.3
• The load's minimum length and width are determined by the current Pad Spread
(see “SPECIFICATIONS” on page 3).
• The load's maximum length and width are determined by its allowable overhang.4
• 1½" [3.8 cm] is the allowable thickness at Maximum Load Capacity.5The load must
be positioned correctly on the lifter and either tilt locks or latches, if present, must
be used when appropriate (see “OPERATION”). If not, the allowable load thickness would
be reduced.6
Note: Standard vacuum pads can stain or deform load surfaces with light colors or soft coatings.
Test such surfaces for damaging effects before using the lifter on them.7
1..... Although concave vacuum pads can also attach to some curved loads, curvature can reduce lifting capacity. Contact WPG for more information.
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.
4..... The allowable overhang is the amount of load material that can extend sideways beyond the vacuum pad without breaking or otherwise being
damaged. This depends on the load material, its thickness, and the angle of handling (if any). Since every material has different physical
properties, the allowable overhang must be evaluated separately for each load type. Contact WPG or an authorized dealer for more
information.
5..... However, the allowable thickness increases as load weight decreases. Contact WPG for more information.
6..... Pad Spacers can reduce the stability of upright loads and allowable load thickness. Contact WPG for more information.
7..... Alternative rubber compounds are available for these purposes. Contact WPG or an authorized dealer for more information.

MRTALPCH6-DC3(RC): #35125 Rev 1.0/12-1914
OPERATING ENVIRONMENT
Make sure the vacuum lifter is intended for use in each work environment, given the following
restrictions:
•
Never use lifter in dangerous
environments.
Metal particles and similar
environmental contaminates
could result in vacuum pump failure.
This lifter is not intended for any environment
that is dangerous to the operator or damaging
to the lifter. Avoid environments containing
explosives, caustic chemicals and other
dangerous substances.
• The work environment is limited by the Operating Elevation and Operating
Temperatures.1, 2
• The lifter is not designed to be watertight.
Moisture can result in
reduced lifting capacity.
Do not
use it in rain or otherunsuitable conditions.
DISPOSAL OF THE LIFTER
After the Service Life of the vacuum lifter has ended (see “SPECIFICATIONS” on page 3), dispose
of it in compliance with all local codes and applicable regulatory standards.
Note: Special disposal regulations may apply to the battery.
1..... Although lifter use may be possible at higher elevations, lifting capacity is reduced whenever the lifter is unable to attain vacuum in the green
range on the vacuum . Contact WPG for more information.
2..... Special provisions may allow the lifter to operate outside the specified temperature range. Contact WPG for more information.
INTENDED USE

Rev 1.0/12-19 MRTALPCH6-DC3(RC): #3512515
OPERATION
BEFORE USING THE LIFTER
Determine whether the vacuum lifter is capable of each intended task (see “SPECIFICATIONS”
on page 3 and “INTENDED USE” on page 13). Then complete the following preparations:
Taking Safety Precautions
•
Read all directions and safety
rules before using lifter.
Always wear appropriate
personal protective equipment.
Be trained in all industry and regulatory
standards for lifter operation in your region.
• Follow trade association guidelines about
precautions needed for each load material.
Selecting a Screen Language
When the lifter is powered up for the first time, the Intelli-Grip®
control unit prompts the operator to select a language for the LCD
screen. Use the buttons as follows:
• To scroll down, press the “release” button ( ).
• To scroll up, press the “attach” button ( ).
• To select a language, press the “function” button ( ).1
Note: A similar process is used to navigate all menus.
1..... To change the language again, refer to the “INTELLI-GRIP®OPERATOR MENUS” section of the SERVICE MANUAL.

MRTALPCH6-DC3(RC): #35125 Rev 1.0/12-1916
Performing Inspections and Tests
• Follow the “INSPECTION SCHEDULE” on page 30 and “TESTING”on page 31.
•
Examine air filters regularly
and service when needed.
Service the 2 air filters whenever a bowl contains
liquid or other contaminates, or an element
appears dirty (see “AIR FILTER MAINTENANCE” in
SERVICE MANUAL).
•
Make sure
notification
buzzer can be
heard over noise
at operator
position.
Make sure the notification buzzer is clearly
audible at the maximum distance between the
operator and the lifter, despite any barriers or
obstacles.1, 2
Checking the 12-Volt Battery
Always check battery
energy before every lift.
While the lifter is powered up, a battery gauge on the LCD
screen displays the current energy level.3, 4
• If battery energy is in the red range, discontinue lifter
use and charge the battery (see “12-VOLT BATTERY
RECHARGE”on page 36).
• If battery energy continues to decrease and you try to
attach the lifter to a load, the notification buzzer will
sound continuously and the LCD screen will display “Lockout (low 12V battery)”, along
with a diagnostic code (see “INTELLI-GRIP® DIAGNOSTIC CODES”on page 38). In this case, you
must charge the battery in order to continue using the lifter.
1..... Maximum buzzer volume is 95 dBA at 2' [60 cm]. If CE Standards apply, consult EN 7731 to make sure the notification buzzer is compliant.
2..... The “Vacuum Test” on page 32 provides a convenient opportunity to check this.
3..... If the lifter remains in “Power Save” mode for a long time, the pump will run periodically to test the battery.
4..... If the battery charger is connected to an AC power source, the reading on the battery gauge will not be accurate and “Replace 12V battery” may
appear on the LCD screen, because the system cannot accurately evaluate the battery.

1A
The optional radio transmitter (fig. 1A) and radio
receiver enable you to activate the lifter's “attach”
and “release” functions at distances up to 250' [76 m],
provided you have a clear and direct view of the lifter and
its status indicators.
To operate a lifter remotely, follow these safety rules:
• Visually verify the status of the lifter and load prior
to lifting.
Make sure nearby personnel are aware of
intended remote control actions.
• Monitor the lifter at all times to make sure it is
functioning as intended.1
• Be sure the load is lowered and supported correctly
before releasing it (see following sections).
Note: To prevent any radio transmission, press the
emergency disconnect button.2
1..... The Remote Control System is designed to prevent multiple lifters from responding. Nevertheless, radio-controlled lifters should be tested to
make sure each transmitter controls only one lifter.
2..... To reset the emergency disconnect button, twist the button clockwise and allow it to spring outward to its original position.
OPERATION

MRTALPCH6-DC3(RC): #35125 Rev 1.0/12-1918
TOATTACH THE PADS TO ALOAD
Make sure the contact surfaces of the load and vacuum pads are clean (see
“Pad Cleaning” on page 35).
Positioning the Lifter on the Load
1) Center the pad frame on the load.1
2) Make sure all vacuum pads will fit on
the load and will be loaded evenly.
Consult the Per-Pad Load
Capacity.
3) Place the vacuum pads in contact with
the load surface.
1..... The lifter is designed to handle the maximum load weight when the load’s center of gravity is positioned within 2" [5 cm] of the lifter’s rotation
axis. Uncentered loads may rotate or tilt unexpectedly.
OPERATION
