Cross-Cabling
Erecting Beams using the Fork Lift Method (NOTE: For an alternate method using a Gin
Pole method, see the AA AnchorSpoan Assembly Manual and increase the number of
workers pulling the beam, or reaplace them with appropriate powered equipment.)
In order to pivot the beams to a vertical position, you must pull the beam from a vertical angle.
This vertical angle can be provided by a forklift, cherry picker, crane, or any other suitable
substitute. We have chosen to show a forklift in our illustrations because they are commonly
available as rental equipment. It is important that the equipment used have a load rating and
“reach” suitable for the weight, height, and span of the beams being installed and that all rig-
ging conform to safety regulations. Cable attachments to the forklift must be secure through all
angles the cable may assume during the pivoting operation and for all heights of the forklift
mast during the process.
Install the beam hook and harnesses, as shown above, with the hooks passing through the end
beam plates at the apex joint onboth sides of the peak of the beam. Pass one end of each
cable under the beam and connect it to the safety ropes. Connect the other end of each cable
to the forklift (or other power lift). Elevate the forks to approximately 15 ft, or more, to provide a
vertical lift. The forklift operator then must coordinate the lifting of the forks and the backing up
of the forklift itself to slowly pivot the beam to vertical. Use caution to keep the angle of pull
such that the beam can pivot freely in its baseplates. Too low an angle will jam the beam
into its baseplates. Too high an angle may actually pull the baseplates from the ground. Either
of these mistakes could conceivable cause damage, or injury; so, be attentive to the smooth piv-
oting action of the beam on its baseplate pins.
The forklift operator does not have a good vantage point of the motion of the beam, so it is rec-
ommended that one worker spot the motion of the beam and signal the forklift operator as it
approaches vertical alingment. When the beam is near vertical and balanced between the fork-
lift and safety ropes held by workers, another worker can install the diagonal beam braces to
secure the first beam. (See the top of page 13). Proceed to the bottom of page 13 to erect the
second beam.
