WARNING
!
PRECAUTIONS
• Always level forks
(horizontally) before swinging
load to side. Swinging
unlevel forks could result
in load slipping from forks.
• The swing mast attachment
has a smaller load capacity
than the standard carriage/
fork attach. Study and
understand the swing mast
capacity chart before
handling a load with swing
mast.
• Read additional capacity
information under “Capacity”
heading on chart.
• Because the swing mast
increases lift height and can
swing load to side; it is
especially important to level
handler before lifting a load
more than 1.2m (four feet)
above ground level. See
page 11.0.
WARNING
!
Do not handle a load with Swing
Mast attachment until you study
and understand the “Swing Mast
Capacity Chart.” If your handler
does not have a “Swing Mast
Capacity Chart,” ask your
supervisor to get one before
using the attachment.
Truss Boom & Truss Boom with Winch (cont.)
Operation continued:
• Position truss boom/winch hook as close as possible to balance point of load
and secure load to boom using short slings or other rigging. Be sure rigging
will not allow load to slip in any direction.
• Open clamps at heel of truss boom far enough to clear load and tilt truss
boom up until truss/bundle contacts heel of truss boom.
• Close clamps to hold load lightly and secure clamps.
• Transport load to delivery site and attach tag lines if load will be freely
suspended.
Swing Mast
Capacity:
Maximum lift capacity is shown on attachment serial number plate. However,
maximum lift capacity applies only to certain areas within boom extension/
