Follow the directions for vacuum lifter ASSEMBLY in the MRTA6-DC lifter's instruction manual, but
instead of suspending the lifter from a crane or other hoisting device, modify the procedure as
follows:
1) Select a forklift which has the capacity and stability required for use with the vacuum lifter:
When the lifter is installed on the forklift, it places the load's center of gravity further away
from the forklift than a load which rests directly on the forks. If the operator fails to take
this into consideration, using the lifter could overload the forklift and cause it to
tip over. Use the following criteria to determine whether a particular forklift could be used:
Calculate the combined weight of the lifter, its options and its maximum load (see
SPECIFICATIONS: Lifter Weight and Maximum Load Capacity in MRTA6-DC lifter's instruction
manual, as well as SPECIFICATIONS: Weight Increase preceding). The forklift must have
sufficient load capacity for this combined weight when the load's center of gravity is located 8
3/4" [222 mm] outward from the fork tips or 50 3/4" [1289 mm] outward from the fork stops,
whichever places the load at a greater distance from the forklift’s front wheels.
Note: Any application of the lifter and the Forklift Adapter must conform to all statutory or
regulatory standards that relate to the forklift when used in its geographical location (eg,
OSHA Standard 1910.178 “Powered industrial trucks” for forklifts used in the USA). Consult
the forklift instructions as needed for further information about its use.
2) Insert the forks into the fork tubes (1) of the
Forklift Adapter: The forks must be inserted
a minimum of 30" [76 cm] for the Forklift
Adapter to be mounted correctly. The forks
should fit inside the tubes as far as possible
but must not extend more than 1" [2.5 cm]
beyond the end of the tubes. The Forklift
Adapter must be oriented as shown in the
illustration.
Using the Forklift Adapter
any other way can endanger the
operator or damage the lifter or load.
3) Use the fork securing screws (2) and lock nuts to secure the Forklift Adapter to the forks:
First tighten all 8 screws down snugly and then retighten each one to 20-25 ft-lbs [27-34 N-
m] of torque. While holding each fork securing screw to prevent it from turning, tighten the
corresponding lock nut against the fork tube [to 25-30 ft-lbs [34-41 N-m] of torque) to secure
the screw in place.
4) Use a safety strap or chain to secure the Forklift Adapter to the forks, in case it should come
loose for any reason: Select a safety strap or chain rated to at least 500 lbs [227 kg] tensile
strength, and run it through both of the back or both of the middle safety strap brackets (3).
Then attach the strap or chain to the forks so as to prevent the Forklift Adapter from coming
off under any circumstances. This is a mandatory safety procedure.
WARNING: Never use adapted lifter with forklift unless safety strap is installed.
5) Once the adapted MRTA6-DC lifter is securely attached to the forklift, complete the
ASSEMBLY as directed in the lifter's instruction manual. Remember to perform Operational
and Load Tests for the lifter as directed in MAINTENANCE: T
