|
|
|||
Jefferson Lab considers forklift attachments and lifting devices to be material handling equipment. As such, they are subject to the requirements of this appendix and ES&H Manual Chapter 6140 Material Handling Equipment Program and its associated appendices.
A forklift attachment is a modification or addition to a forklift that affects its capacity, stability, or safe operation.
The requirements of this document are performed in coordination with ES&H Manual Chapter 6140 Material Handling Equipment Program and ES&H Manual Chapter 6145 Material Handling Equipment – Forklifts and Attachments.
NOTE: Management authority may be delegated at the discretion of the responsible manager.

Requirements
·
Prior to each use the forklift operator inspects
the attachment in accordance with the requirements of ES&H
Manual Chapter 6145 Appendix T3 Inspection and Maintenance – Forklifts and
Attachments.
5.2.1 Jib Booms - Telescoping
This
attachment can 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.
|
Load charts provided by
the boom manufacturer cannot be used to determine the authorized load
carrying capability of the boom on a particular forklift. |
·
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.
|
Rigging gear that complies with the above standards must not be used in a horizontal pull configuration. |
·
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 slides 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 against the mast.
·
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.
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.
|
When transporting hazardous waste or traveling on rough surfaces attach the ratcheting strap to the bottom drum grip and tighten it around 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.
5.2.3 Forklift Load Suspending Device
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 2,000lb. 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 exteed 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.
|
Rigging gear that complies with the above standards must not be used in a horizontal pull configuration. |
o Accomplish the lift, using spotters and signalmen as needed.
5.2.3.2
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.
5.2.3.3 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.
