SWING

MAST

SIDE

SHIFT

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.

Maximum lift capacity is shown on attachment serial number plate. However,

maximum lift capacity applies only to certain areas within boom extension/
