The objective of this guide is to define minimum requirements for in-service inspections and should be
mandatory used, unless a specific regulation in force is available in a country. In this latter case, the criteria
enclosed could be added for a professional management of a lifting equipment park.
This is the free synthesis of the following:
• Lifting Operation and Lifting Equipment Regulations 1998 (LOLER),
• French Regulation which came in force on March 1
st
2004 for inspection of lifting equipment and
their hoisting accessories,
• BV experience feedback,
It gives a general indication of some of the main requirements focused on priority to safety criteria and it is
organised to be fulfilled during the inspection.
After satisfactory completion of examination a Certificate including an annex shall be issued, and a Defect
Report will be issued for equipment failing the acceptance criteria for thorough inspection.
If some appliances identified by the customer in a contract are not available, a Non Available Report has to be
issued including a detailed list of accessories not inspected.
Note: The paragraph numbering adopted in the following guides, for every equipment, is derived from a global
matrix valid for all lifting appliances and their accessories
As a result, the numbering for particular lifting equipment - e.g. Accessories - does not include all paragraphs of
this set.

Standardized link chains are anchored by various means
such as pegs (Fig. 12) or screw with protective buffers (Fig.
11).
The other end, if attached to the hook is stuck in the forks,
all remaining kept in a protective bell (Fig. 10).
Check that every point of mooring chains is in good
condition and can’t cause inadvertent uncoupling.
Example: excessive clearance of the pin in the row due to a
severe wear, no stopper at the end of the shaft, improper
fixing of the flange, cracks of welded ears of the flange.
Fastening system on the drum
The fastening system shall be easily checked. The manufacturer must be able
to justify by calculation that the fastening system is able to resist at least 3 times
the safe working load of the cable.
Note: There is no regulatory requirement regarding the minimum number of
windings that must remain on the drum regardless of the working position of the
hook, except for appliances “non-CE” marked appliances and used in building
construction and public works for which the value 3 is demanded.
Ensure that:
Fastening endpoints are in good conditions: the position of the cables is
correct with the fasteners,
Fasteners are properly positioned and secured on the equipment,
No cracks, no releasing,
No slipping and no strand failure at the output of the fasteners.

15.0 Below-the-hook e.g. C-hooks
Drop in load due to sudden break of
the hook anchoring point from the
crane hook, unbalance due to
deformation of the C-Hook structure
C-Hook are to be designed and manufactured to specific
standards by the manufacturer.
C-Hooks are maintained as per manufacturer’s
instruction.
Perform a complete visual inspections during no-load and on-load
tests to detect distortions or bents,
Check paint parts and ask for NDT if doubt is raised.
Bear special attention about welds repaired and uncontrolled
deposition welding

Rev 00
1) First do a preliminary visual inspection of the entire equipment to look for
obvious problem areas with no bail wear, no bent bails and no bent lower arm.
Then ensure that the manufacturer’s nameplate and safety labels are attached
Concentrate on visually looking for cracks at the crotch of the C-hook
Look for paint cracking at the crotch (note that many times the base metal will
yield more than the hardened layer of paint on the surface).
Welds that hold the bail to the base metal should be inspected. Especially those
that hold the counterweights onto the C-hook.
2) The next inspection is to verify that the lower arm has not been bent so that it
is out of parallel with the C-hook, or bent down because of excessive load (note
that more than 12 mm variance would be considered unacceptable).
3) Pads that may be applied on the nose of the C-hook or on the back vertical
riser, revolving belts or other assemblies that protect the coil should be
inspected even it is usually not structural concern.
4) Finally the following items could be performed after removing paints and other
debris: Dye-penetrant checks at lower and upper crotch of the C-hook as well as
at all welds on the bail assembly (and bail pin if applicable)

Rev 00
Note 1: Safety recommendation about welding.
Many C-hooks are made from special alloys and require special welding procedures, so welding on C-hook should only be done after consulting with
the manufacturer.
No welding should be done on any portion of the equipment and spare parts that had not been originally welded by the manufacturer on under his
control.
File manufacturer should be made available on request.
Note 2: Pay attention especially when components of the work processing line are among the least expensive and repetitive used.

Coil Lifters are maintained as per manufacturer’s
instruction.
Perform a complete visual inspection during no-load and on-load
Check paint parts and ask for NDT (Non Destructive Testing) if doubt
is raised,
Check the electrical control components,
Bear special attention about geometrical alignments.

Rev 00
1) First do a preliminary visual inspection of the entire equipment to look for
obvious problem areas with no bail wear, smooth operation of the sliders,
smooth rotation of the grab (if applicable), all guards and stops are attached.
Ensure that the manufacturer’s nameplate and safety labels are attached
Check each of the safety features associated with the lifter (interlock that
prevents loss of control of the load, including flappers or proximity sensors).
Note that many coil lifters have a device that detects when a coil is engaged and
simultaneously disables the ability of the grab to open the sliders. If there is any
indication that this safety feature does not work, the lifter should immediately
tagged out of service until repairs can be made.
2) Structural components can be inspected through visual inspection of slider,
including verification that the wear surfaces are properly greased and have no
excessive gouges.
3) The welds at the “knee” of the slider (the 90°t urn when the slider becomes
the vertical leg) and the horizontal pads should be checked for obvious cracks.
4) Electrical devices, including the wiring to the sensors and motors should
reveal no indications of burned or cracked wire insulation, foreign material lying
or obvious loose connections. Discrepancies to look for include frayed wires,
sliced insulation, stretched or taut wires, discoloured insulation or broken
connectors.
Once the lifter is re-energized, the pendent should be tested through all of its
operations to verify that all controls function properly.
5) Mechanical drive and rotation (if applicable) components should be inspected
for wear alignment. Verify the integrity of the bearings, chains, belts, couplings,
clutches and other drive components. During the drive system operation watch
for noises or irregularities that could indicate potential problems.
Note: Safety recommendation about NDT, dimensional checks,
If dye-penetrant checks are performed, it should be after removing paint, oil and
other debris. It should indicate no cracks in the welds or in the base metal of the
pin.
Alignment of the bull gears in the drive components: significant changes over
time in angles (incl. gear rack) may indicate unacceptable wear or bearing
failure.

Rev 00
Measure the clear height with the sliders closed and then when opens. Most
models experience a difference in the clear height in these two positions when
the slider droops at their furthest extension. (If this clear height sharply increases
over time or the sliders hang up when fully extended, there is indication that the
wear surfaces have excessive wear).
Legs should operate simultaneously. If the coil grab has a drive and idler side
configuration, measure the difference between when the drive side starts
movement and when the idler actuates. If this difference sharply increases over
time, bearing, chain or belt failure may be indicated. Chains or belts should be
adjusted. An approximately 2% slack is allowed.

Rev 00
First do a preliminary visual inspection of the entire tong crab to look for obvious
problem areas: bail wear, smooth operation of the linkages and safety latch, all
guards and stops are attached.
Ensure that the manufacturer’s nameplate and safety labels are attached.
Then the following components are reviewed:
Inspect the bail and determine the loss of material that has occurred
where the tong interfaces with the hook.
Inspect the pins that connect the linkage of the tong. If there is more
than 3 to 5% of wear indications, ask for replacement or consult the
manufacturer.
Inspect the automatic latch. No wear at interface between the piston
and the catch:
are the pins that connect the linkage straight and round? No
distortion.
are the retaining devices that hold the pins in place (collars, roll
pins, cotter pins) intact or working properly?
are the bushings in good condition, or are they cracked and worn?
are the legs of the tong straight, and do they meet in the center
when the tong is closed? Bent linkages could indicate the tong has
experienced excessive loadings and have caused permanent
yielding.
have any unauthorized modifications been performed on the tong?
operate the grab and verify that it works smoothly and properly
(swivel, rotate if applicable)
are the pads or points worn to the extent that they need
replacement? It is important that these interface points are
maintained since the gripping ratio or coefficient of friction that they
create may be a basis of the original design

Rev 00
Note 1: Safety recommendation about NDT, dimensional checks,
If dye-penetrant checks are performed, it should be after removing
paint, oil and other debris. It should indicate no cracks in the welds or
in the base metal of the pin.
- bail assembly: no crack indication is the criteria
- pins that hold the linkages together: “no crack observed” is the
minimum criteria that we find acceptable.
Note 2: Minimal maintenance
The simplicity of the tong grab leads to minimal maintenance
requirements.
One important item on the preventive maintenance program for a tong
crab would be lubrication of the tong where there are sliding interface
locations or where grease fittings are provided.
Other items on the preventive maintenance might be replacement of
pads or points.

15.3 Below-the-hook e.g. Spreader Beam
the spreader beam anchoring point
from the crane hook or load
anchoring points, deformation of the
spreader beam structure

Spreader beams are maintained as per manufacturer’s
instruction.
Perform a complete visual inspection during no-load and on-load tests
to detect distortions or bents,
Check paint parts and ask for NDT if doubt is raised,
Check the electrical control components,
Bear special attention about geometrical alignments, cleanliness and
minimal maintenance requirements.

Rev 00
Lifting beams come in many different configurations, but inspections of them is very
similar and “standardized”
The inspection starts with a global review of the beam, looking for obvious material
distortion, bent hooks, missing retaining pins, keeper bars, safety signs and
manufacturer’s labels.
Then inspect the hooks or attachment points of the load to the beam:
- Are the hooks bent? If so, they need to be replaced,
- Are the pins that connect the “J” hooks or other lifting points to the beam in
good condition? If there is more 3 to 5% (obvious indentations), ask for
manufacturer’s requirements,
- For beams with adjustable lifting points or bails, carefully inspect the
mechanism that holds the assembly in position. Is there sufficient wear or
degradation that would allow the assembly to slip out of position inadvertently
during a pick? Are the pins or clips that hold the position in good condition?
- Are the shackles/links/hooks/slings in proper condition? Do they have the pins
to prevent the load from being released? Are they sized properly if they have
been substituted from the original design?
Visually inspecting the lifting beam for obvious weld cracks or other signs of
distortion would be the next step.
Cracks in spacers or other non-load bearing members need to be evaluated to
determine if they would be detrimental to the operation of the beam (see note1
below). A particular attention will be born upon the bail or bail pin between the
crane and the beam for obvious wear and excessive indentation.
If the lifting or spreader beam is made of channel, I-beams or other structural
members, checking the straightness of the beam may indicate if the beam has been
subjected to excessive forces or loads. A simple piece of string pulled taught along
the edge of the structural member will quickly determine the difference in the
camber and sweep of the lifter. As a general rule, anything in excess of 3°out of
alignment should be investigated.
Telescopic magnet spreader beam

Rev 00
Note 1: Safety recommendation about NDT, dimensional checks,
If dye-penetrant checks are performed, it should be after removing paint, oil
and other debris. It should be performed
- at the critical loading areas on all hooks or other members that connect
the load to the beam.
- at all structural welds in the bail assembly and the beam.
Note 2: Maintenance
Maintenance of a lifting beam is usually limited to replacement of protective
pads, liners or hardware that attaches the load to the beam. On beams with
adjustable bails or hooks, properly greasing the contact points would be
advisable.
Note 3: Motorized equipment
Many lifting beams are motorized for rotation or other axis motions. In such a
situation, many of the items covered in the motorized coil lifter section will
pertain, including electrical safety, bearings, gears, clutches, reducers, etc…

15.4 Below-the-hook e.g. Chains, Hooks and Slings
the chain, hook or sling or the
anchoring point from the crane
hook.
Chains, hooks and slings are to be designed and
manufactured to specific standards by the manufacturer.
Chains, hooks and slings shall be regularly maintained.
Perform complete visual examination of the chains, hooks and slings
for physical damage which can affect the integrity of the lifting tool.
Check paint parts and ask for NDT if doubt is raised on chains or
hooks.
Hook Inspection. Usual requirements:
Physical characteristics, such as capacity, serial number, type and
manufacturer of hooks.
Hooks are visually inspected for excessive wear, deformation, out of plane
bending, excessive gouges and missing capacity markings.
Throat and saddle measurements of hook are taken to keep records of
stretch or growth from at least year to year.
Hooks are inspected for invisible cracks using a Magnetic Particle test or a
Liquid penetrant test.
Each hook that passes will be tagged with a colour coded inspection tag or
sticker, demonstrating that it has been checked.
Hooks which do not pass inspection will be tagged with a caution tag as well
as a red paint mark.
Web sling inspection information. General rules to be applied:
Identification: synthetic fibre web slings must be permanently identified
with the manufacturer’s name or mark, code or stock number, the working load
limits for the types of hitches permitted and type of synthetic web material.
Safety hook

Rev 00
Damage: fibre web sling must be removed from service when the following
circumstances occurs:
The length of an edge cut exceeds the web thickness.
The penetration of abrasion exceeds 15% of the webbing thickness when
taken as a proportion of all piles.
Abrasion occurs on both sides of the webbing and the sum of the abrasion
on both sides exceeds 15% of the webbing thickness when taken as a
proportion of all piles.
Warp thread damage up to 50% of the sling thickness extends to within 1/4
of the sling width of the edge or exceeds 1/4 the width of the sling.
Wrap thread damage to the full depth of the sling thickness extends to within
1/4 the sling width of the edge or the width of damage exceeds 1/8 the width
of the sling.
Weft thread damage allows warp thread separation exceeding 1/4 the width
of the sling and extends in length more than twice the sling width.
Any part of the sling is melted or charred, or is damaged by acid or caustic.
Stitches in load bearing splices are broken or worn.
End fittings are excessively pitted or corroded, cracked, distorted or broken.
A combination of the above types of damage of approximately equal total
effect is present.
Cuts
Chemical attack
Heat or friction damage
Damaged or deformed fittings
Replacement guidelines: if damage can be identified, such as that listed below,
slings must be removed immediately from service, and return them to service only
when approved by qualified individuals.
Acid or caustic burns.
Melting or charring of any part of the sling.
Holes, tears, cuts or snags.
Broken or worn stitching in load bearing splices.
Excessive abrasive wear.
Knots in any part of the sling.
Excessive pitting or corrosion, or cracked, distorted fitting.
If you see our Red Core warning yarns.
Distortion of the sling.
The sling has an identification tag that is in any way unreadable.
Anytime a sling is loaded beyond its rated capacity or reason.
Cargo Net
Note : Sling angles have a direct and oftentimes dramatic affect on the
working load limit of a sling

Rev 00
Chain inspection information checklist:
The identification tag includes vital information, including the grade of chain, the
nominal chain size, the number of chain legs and the rated loads for the sling
assembly. Always look for proper and clear identification, especially the working
load limit.
In order to avoid this hazard, keep the following points in mind:
Perform and record frequent and periodic inspections of chain slings
Inspect of all new, altered, modified or repaired chain slings. Knowing
that welding repairs or building up worm surface is prohibited.
Proper measurements using precision instruments of each link
component should be performed to provide a benchmark for allowable
tolerances.
Written records containing the most recent periodic inspection should
be maintained by the owner or user of the chain sling.
Ensure all slings have identification and warning tags.
Maintain records including test certifications, drawings, and
instructions of each sling.
Note: Safety recommendation about NDT, dimensional checks,
If dye-penetrant checks are performed, it should be after removing paint, oil and
other debris. It should be performed
At the critical loading areas on all hooks or other members that connect
the load to the beam.
At all structural welds in the bail assembly and the beam.
A Magnetic Particle Testing (also called magna-flux testing) could be proposed
as also a non-destructive test method used to detect problems at or near the
surface in ferromagnetic materials for items such as:
Eyebolts
Hooks
Welds on specialty lifters
Swivel hoist rings
End effectors
Any kind of forks
