Maintenance and Inspections:
Only trained, authorized persons should inspect of and maintain this device. The end-user is responsible for
ensuring that the lifter is properly inspected and maintained.
RECORD OF SATISFACTORY CONDITION (THE “RECORD”)
Record the condition of the
stacker
before putting it into service. Thoroughly photograph the unit from multiple
angles so that all operating mechanisms are clearly visible. Take close range photographs of the labeling applied to
the
stacker
. Raise and lower the
forks
. Describe the operation of the winch. Describe sounds heard as the
forks
rises and descends. Include detailed descriptions about the frame,
winch
, rollers, wheels, casters, carriage, mast
rollers, and the lifting mechanisms (winch, cable, and pulleys). How much effort is required to turn the winch?
Collate all photographs and writings into a single file. Give the file a name that clearly identifies it. This file is a
record of the unit in satisfactory condition. Compare all inspection results to the record to determine whether the
truck is in satisfactory condition. Purely cosmetic changes, like damaged paint/powder coat are not changes from
satisfactory condition. However, touch-up paint to be applied to all affected areas as soon as damage occurs.
INSPECTIONS & MAINTENANCE
Regular inspections and maintenance are necessary to keep the
stacker
in normal condition. Compare the results of
each inspection to the
Record
to determine whether the unit is satisfactory condition or requires repairs or
replacement parts. If you are uncertain whether a part requires repair or replacement, contact
Technical Service
for
assistance.
•
Periodically lubricate moving parts.
•
Keep the product clean and dry.
•
Only use manufacturer-approved replacement parts.
At
least once per week, inspect the following components
:
1. Winch, winch mounting bracket, cable, carriage rollers, and pulley
.
Cycle the
forks
up and down. Listen for
unusual noises and watch for binding or rough movement as the carriage moves. If
the carriage does not move
smoothly or makes noise as it moves up or down the upright, apply a silicon wax or
silicon spray to the inside
of the mast frame. Examine the winch. Make sure that the spool is intact and rotates
smoothly when the
handle is turned. Inspect the mounting bracket. The winch should be solidly attached to the
bracket. Tighten all
loose fasteners. Lower the carriage and examine the
cable for reeving, stretching, thinning
portions, etc.
Confirm that the pulley rotates freely and is securely fastened to the mast.
2. Frame (mast, base): Examine the frame members for damaged welds, severe rusting, cracks, bends, etc.
Remove rust with steel wool. Clean the affected areas and apply touch-up paint.
3
. Wheels, rollers, and casters: Check each wheel, caster, and roller for wobbliness, damage, and severe wear. All
should roll smoothly. Clean them to remove debris from the surfaces, if necessary.
4
. Hardware: Examine the pins, bolts, nuts, etc. Tighten loose fasteners. Replace all damaged fasteners.
Maintenance:
Implement a maintenance program to ensure that the lifter functions normally for as long as possible.
Page 9 of ANSI/ITSDF standard B56.10-2006, “Manually propelled high lift industrial trucks”, describes recommended
maintenance procedures. A copy of the standard is downloadable for free from the ITSDF website (
www.itsdf.org
).
Apply t
hose recommendations in conjunction with the following steps.
1. Tag the lifter, “Out of Service.”
2. Inspect the lifter as described above. If deformity, corrosion, rusting, or excessive wear of structural members is
present, permanently remove the lifter from service.
3. Remove any dirt or other matter from the cable and pulleys and other lifter surfaces.
4. Perform all other necessary adjustments and/or repairs. DO NOT modify the lifter.
5. Make a dated record of the repairs, adjustments and/or replacements made.
