Purpose
The purpose of this document is to describe forklift attachments approved for use with Jefferson Lab-owned forklifts and to outline the inspection requirements of these devices.
Forklift
attachments introduce additional hazards that the operator must be aware
of. Use of forklift
attachments requires additional training not included in SAF 502 or 502A. Refer
to ES&H Manual Chapter
6145 Forklift Safety for training requirements.
The Occupational Safety and Health Administration (OSHA) standard governing the safe use and operation of forklifts is titled Powered Industrial Trucks. This appendix uses “forklift” to describe these vehicles.

Expectations
4.1
Forklift
Attachment Pre-Use Inspection:
·
Prior to each use the forklift operator inspects
the attachment to ensure:
o The
nameplate is in place and markings are legible.
o Verify
that the restraint mechanism is in place and functional. (The restraint mechanism is generally chains
with hooks or shackles on the ends which hold the attachment in the proper
position on the tines during use.
o The
attachment does not show signs of damage or failed components. Look for:
§ Bent
members,
§ broken
welds,
§ bent or broken bolts.
o Verify
that the attachment is approved for use with the selected forklift. The forklift dataplate
must list the specific attachment.
4.2
Forklift
Attachments Use:
4.2.1
Telescoping
Jib Booms
Introduce
substantial changes to the stability of a forklift. The distance a load is suspended in front of
the forklifts mast (static load) and the effects (bumps and dips) have on the
load (dynamic load) result in significant reduction in the capacity that a
forklift can safely lift.
·
The
load rating of a specific forklift and telescoping boom combination is
determined by the forklift manufacturer.
·
A load chart has been created for each
telescoping boom indicating the load capacity at the various boom positions for
each forklift that is approved for use.
A load chart is attached to each boom.

·
Determine the weight of the object to be lifted
and the amount of boom extension necessary for a lift.
o Refer
to the telescoping boom load charts to determine which boom/forklift
combination has the required capacity at the desired boom hook position.
·
Select rigging gear necessary to attach the load
to the boom
o
Rigging must be approved gear that complies with the requirements
of American
Society of Mechanical Engineers (ASME) B30.9 Slings and ASME B30.26
Rigging Hardware: Safety Standard for Cableways, Cranes, Derricks, Hoists,
Hooks, Jacks, and Slings.

·
Adjust
the forks so that the inside width between the forks will fit into the fork
pockets. At least one fork must be
locked to the bedplate of the mast.
· Drive the truck forward to slip forks into the fork sleeves until the boom to the furthest position, away from the tips of the tines, against the mast. Attach safety chain to mast to secure the boom attachment in position.
·
Accomplish the lift, using spotters and
signalmen as needed.
o Many
hook positions are available under the boom.
The outer most position is generally the load carrying position when in
use. The remaining hook positions may be
rigged to steady the load as needed.
4.2.2
Drum
Lifter
The eagle-beak drum lifter provides a convenient way to lift, transport and load 30- or 55-gallon single drums. The drums may be open and closed head plastic, steel and fiber drums with a top lip strong enough to support the weight of the drum and has a maximum capacity rating of 1000 pounds.
·
Adjust
the forks so that the inside width between the forks will fit into the fork
pockets. At least one fork must be
locked to the bedplate of the mast.
· Drive the truck forward to slip forks into the fork sleeves until the tips of the tines contact the closed end of the fork sleeves. Attach safety chain to mast to secure drum lifter attachment to the forks.
· Tilt the fork truck mast forward and drive the tuck with the forks near the floor level to center the lifter in front of the drum until the lifter contacts the drum at the bottom drum grip.
· With the mast still in the tilted forward position, raise the forks up.
· When the upper jaw on the drum lifter engages the top of the drum lip, straighten the mast and raise the forks to transport the drum.

· To release the drum, remove ratcheting strap. Lower the forks so that the drum sets flat on the floor and continue to lower forks until the upper jaw disengages itself.
4.3
Forklift
load suspending device use:
4.3.1
Single
Hook Fork Beam
Single hook fork beams are seldom used at Jefferson Lab; however, they provide positive handling of loads otherwise impractical for forklifts. Jefferson Lab maintains three fork beams, each rated for a 2,000 Lb. load. These devices do not require approval from the forklift manufacturer for use because they do not change the load carrying capacity or stability of the vehicle.
Forklift operators are authorized to use fork beams as needed in accordance with the following instructions. Contact the MHSR for introductory training and access to a beam.
· Adjust the forks so that the outside inside width between the forks is 20”. At least one fork must be locked to the bedplate of the mast. The tines should be near the center of the mast.
· Lift the 20# fork boom into position on the tines. The boom may be positioned near the mast or as far away from the mast as the forklift data plate will allow not to exceed a rated load center dimension.
· Tighten both screw retainers to contact the bottom of the tines.
·
Select rigging gear necessary to attach the load
to the boom
o
The rigging must be approved gear that complies with the
requirements of ASME B30.9
Slings and ASME
B30.26 Rigging Hardware: Safety Standard for Cableways, Cranes, Derricks,
Hoists, Hooks, Jacks, and Slings.

o Accomplish the lift, using spotters and signalmen as needed.
4.3.2
Jefferson
Lab 24,000# S2 Shield Block Lifter
This
device has been engineered and fabricated at Jefferson Lab to permit movement
of individual 24,000# S2 Shield Blocks using the pre-engineered lift points of
the shield blocks. This device
does not require approval from the forklift manufacturer for use because it
does not change the load carrying capacity or stability of the vehicle.
·
The Hyster lift truck
model H360XL (better known as Crusher) has the lifting capacity to lift and
transport 24,000# shield blocks. No
other forklift at Jefferson Lab has the capacity to use this lifting device.
·
Adjust
the forks so that the inside width between the forks will fit into the fork
pockets. Both forks must be locked to the bedplate of
the mast.
·
Drive the truck forward to slip forks into the
fork sleeves until the restraining tab firmly fixed to the block lifter passes
the mast bedplate, lower the forks as needed to permit this positioning. Raise the forks to pick up the block lifter
load then inspect the position of the restraining tab for proper engagement
behind the mast bedplate.
·
Center the block lifter over a S2 Shield Block
and lower the block lifter sufficiently to permit engagement of the attached
load hooks onto the pre-engineered
lift points of the shield block.
·
Raise the block lifter with suspended
shield block load and transport to the desired location.
4.3.3
Jefferson
Lab 9100# Pallet Crusher
This
device has been engineered and fabricated at Jefferson Lab to permit the
compaction of wood crates and pallets in an open top 40 cu yd dumpster. This device does not require approval
from the forklift manufacturer for use because it does not change the load
carrying capacity or stability of the vehicle.
·
The Hyster lift truck
model H360XL (better known as Crusher) has the lifting capacity to lift this
device to the required height for compaction.
No other forklift at Jefferson Lab has the capacity to use this lifting
device.
·
Adjust
the forks so that the inside width between the forks will fit into the fork
pockets. Both forks must be locked to
the bedplate of the mast.
· Drive the truck forward to slip forks into the fork sleeves until the tips of the tines contact the closed end of the fork sleeves. Attach safety chain to mast to secure the pallet crushing device to the forks.
· Lower the pallet crushing device on top of wood crates and pallets placed in the dumpster to break the wooden members of the crates and compact the discarded material.
4.4
Forklift
Attachment Periodic Inspection and Maintenance:
· Forklift attachments and load suspending device are inspected and serviced annually. A written inspection report is maintained by the MHER for each attachment and device.
· Inspection Criteria:
o Verify
that the forklift data plates are in place on each forklift listed on the
attachment load chart.
o Remove surface rust and lubricate all pivots and screw threads with light machine oil.
o Replace ratcheting strap on the eagle-beak drum lifter.
o The
nameplate is in place and markings are legible.
o Verify
that the restraint mechanism is in place and functional. (The restraint mechanism is generally chains
with hooks or shackles on the ends which hold the attachment in the proper
position on the tines during use.
o The
attachment does not show signs of damage or failed components. Look for:
§ bent
members,
§ broken
welds,
§ bent or broken bolts.
o Inspect the carbon fiber cable locking mechanism for adequacy. Lubricate the lock wafers with a graphite lock lubricant.
