AERIAL LIFT OPERATIONS

This section emphasizes overall operating practices
for aerial lift operations.  This information is presented
in the order of probable use while operating first from
the  ground,  then  from  the  platform  and  close  to
energized conductors.

Start Up Procedures When Operating From the
Ground:

Position the truck as described in this section.

In extremely cold weather allow the aerial lift to idle a
few  minutes  before  engaging  a  load.    Further
consideration of cold weather operation is addressed
in Service Procedures Section of Service Manual,
“Hydraulic Oil Recommendations”.

CAUTION

:

IF AN AERIAL DEVICE HAS

SET IDLE FOR AN EXTENDED LENGTH OF TIME
(I.E. OVERNIGHT)  OPERATE IT FROM THE
LOWER CONTROLS THROUGH ITS FULL
RANGE OF MOTION SEVERAL TIMES BEFORE
AN OPERATOR ENTERS THE PLATFORM.

This  procedure  confirms  that  the  lift  is  operating
properly and purges any air that may have become
entrapped  in  the  hydraulic  system.    Select  lower
control  operation  with  the  lower  control  selector
switch.  Refer to the diagrams of lower controls in
this section.  Always disengage the boom tie down
before initiating any lift movements.

If  there  is  any  kind  of  malfunction  during  this  test
run, shut down the unit immediately.  Do not operate
the lift again until the problem has been corrected by
the service department.  Operate each lift function
from the lower controls by moving the spring-loaded
control switch in the desired direction, until motion
begins.  To terminate a lift movement allow the spring-
loaded  control  switch  to  return  to  the  centered  or
neutral  position.    The  standard  rotation  limit  is
activated electrically. The boom raise, lower, extend
and retract movements, however, are mechanically
limited.

DANGER:

NEVER REVERSE OR

STOP THE DIRECTION OF LIFT TRAVEL
SUDDENLY AND AVOID REACHING THE END OF
BOOM RANGE AT EXCESSIVE SPEEDS.
STRUCTURAL DAMAGE OR INSTABILITY MAY
RESULT CAUSING DEATH OR SERIOUS INJURY.

mph (48 km/hr) or there is a threat of an electrical
storm.

2.

After leaving the cab chock the wheels.  This is
extremely  important  because  the  brake
systems on some larger trucks have a critical
weakness.  They may be engaged by locking
the drive shaft behind the transmission.  If the
weight is reduced from one of the rear wheels,
by the position of the lift, the truck differential
can allow the truck to roll.  Refer to the diagram
below for proper way of chocking the wheels.

DANGER:

NEVER OPERATE THE

LIFT WITHOUT SETTING THE PARKING BRAKE
AND CHOCKING THE WHEELS.  A ROLLING
TRUCK MAY CAUSE AN ACCIDENT RESULTING
IN DEATH OR SERIOUS INJURY.

3.

Set up adequate cones or barricades to mark
the  boundaries  of  the  work  site  and  alert
pedestrians and motorists.  Never work outside
the boundaries.
