SKIP HOOKS
GRADES 8, 10 AND 12
Original in compliance with 2006/42/EC
1 DESCRIPTION AND INTENDED USE
THIELE skip hooks with clevis are exclusively intended as end
fittings of permanently mounted sling chain assemblies on skip
loader vehicles for the attachment of corresponding containers
according to DIN 30720 or similar. In this case, every skip hook
embraces a corresponding container suspension pin.
THIELE skip hooks are designed as self-locking hooks based on
EN 1677-3, which lock automatically when loaded. The hook
opening is smaller than the contour of the securing collar at the
end of the suspension pin. This means that a skip hook cannot
slip off the suspension pin when it is locked.
The integrated clevis is used to attach a chain strand.
The following types are defined by the grade of the associated
chain (TWN = THIELE shop standard):
• Grade 8:
TWN 1399
• Grade 10:
TWN 1899
• Grade 12:
TWN 2499
Skip hooks may only be used:
• within the permissible working load limits,
• within the permissible temperature limits,
• by instructed and authorized persons.
THIELE skip hooks comply with the EC Machinery Directive and have an operating
coefficient of at least 4 in relation to the working load limit.
The skip hooks are marked with the nominal chain size and grade (NG = Nominal size),
manufacturer's mark and traceability code.
THIELE skip hooks are designed to withstand 20 000 dynamic load changes under
maximum load conditions. In the event of higher loads the working load limit must be
reduced.
The skip hooks are powder-coated in colour depending on the grade.
The skip hooks must not be used for transportation of persons or lashing.
2 SAFETY NOTES
Risk of Injury!
Never walk or stay under lifted loads!
Make sure to use hoisting/
attachment means free from defects!
• Operators, fitters, and maintenance personnel must in particular observe the
operating instructions of the sling chain assemblies and loads to which the skip hooks
are mounted, documentations DGUV V 1, DGUV R 109-017, DGUV I 209-013 and
DGUV I 209-021 issued by the German Employers' Liability Insurance Association, as
well as standard specifications EN 818-6.
• In the Federal Republic of Germany, the operational safety ordinance (BetrSichV) has
to be implemented and the technical rule for industrial safety TRBS 1201, in
particular Annex 1, Chapter 2 "Special regulations for the use of working equipment
for lifting loads" must be observed.
• Outside the Federal Republic of Germany, the specific provisions issued locally in the
country where the items are used must also be observed.
• The directions given in these mounting instructions and specified documentations
relating to safety, assembly, operation, inspection, and maintenance must be made
available to the respective persons.
• Make sure these mounting instructions are available in a place near the product
during the time the equipment is used. Please contact the manufacturer if
replacements are needed. See also Chapter 10.
• When performing work make sure to wear your personal protective equipment!
• Improper assembly and use may cause personal injury and/or damage to property.
• Assembly and removal as well as inspection and maintenance must exclusively be
carried out by skilled and authorized persons.

• Structural changes (e.g. welding, bending) are impermissible. Never attempt to make
the opening of the skip hooks smaller by bending or welding in intermediate
elements.
• Operators must carry out a visual inspection and, if necessary, a functional test of
the safety equipment before each use.
• Only fit sling chains of the same nominal size (nominal chain diameter - grade).
• Operation without a functioning safety lever is not permitted.
• Never put to use worn-out, bent or damaged skip hooks.
• Do not overload skip hooks or chains. Be sure to observe the working load limit of
the overall vehicle system.
• Do not use force when mounting/positioning the skip hooks.
• Self-locking hooks may only be put under load at the bottom of the hook and not at
the tip of the hook. Clamping of the load at the tip of the hook between the upper
and lower part is not permitted.
• Make sure the load can take the forces to be applied without suffering deformation.
• Lateral loads are not permitted due to the design. Skip hooks must be able to align
themselves in the direction of loading.
• Avoid sharp edges.
• Only lift loads that are freely movable and not attached or fastened.
• Do not start lifting before you have made sure the skip hooks are locked and the load
has been correctly attached.
• Make sure no one including you (operator) is in the way of the moving load (hazard
area).
• During lifting/hoisting make sure your hands or other body parts do not come into
contact with hoisting means. Only remove skip hooks manually (use your hands).
• Make sure that the sling chains are not twisted.
• Avoid impacts, e.g. due to abruptly lifting loads with hoisting means in slack
condition.
• Never move a suspended load over persons.
• Never cause suspended loads to swing.
• Always monitor a suspended load.
• Put the load only down in flat places/sites where it can be safely deposited.
• Take care for sufficient place for the personnel to move when choosing the route of
transportation and storage location. Danger to life and risk of injury by crushing
hazards.
• In the event of doubts about the use, inspection, maintenance or similar things
contact your safety officer or the manufacturer!
THIELE will not be responsible for damage caused through non-observance of the
instructions, rules, standards and notes indicated!
As regards grades 10 and 12 THIELE does not give its general approval to the assembly
of components stemming from different manufacturers!
Working under the influence of drugs, medications impairing the sense and/or
alcohol (including residual alcohol) is strictly forbidden!
