Operating instructions for ACTEK hoist rings
SHR Series, SHRZ Series, HD Series and SSHR Series
General principles for the use of the hoist rings:
The instruction manual is to be kept together with the certificate
and the CE - Declaration of Conformity.
The falling of loads, caused by the failure and/or incorrect use and
handling of slings or their individual parts, poses a direct danger
to the life or health of persons who are in the danger zone of
lifting operations.
These operating instructions contain information on the safe use
and handling of the lifting gear. Before using the lifting gear, the
persons in charge must be instructed in its handling and use by a
competent person.
The following applies in principle:
- The permissible load capacity (see marking) of the host ring
must correspond to the load. If the marking is missing or illegible,
the load handling attachment must not be used.
- There must be no danger points (e.g. crushing points, shearing points,
or impact points) which could hinder or endanger the slinger and/or the
transport.
- The basic material and the design of the load must be able to withstand the
forces to be applied without deformation.
- Stresses, e.g. due to off-centre application of forces, which lead to
uneven load distribution must be taken into account in the selection of the
load must be taken into account when selecting the load-bearing device.
- If extreme stresses or strong dynamic loads (shock effects) can occur, this
must be taken into account when selecting the sling and the load capacity
and the load-bearing capacity.
- Lifting gear must not be used for transporting people. Persons must never
be in the danger zone of the suspended load.
- Lifting gear must not be brought into contact with acid and other aggressive
media. It should be noted that acid vapours can also occur in certain
production processes.
- Never modify slings unauthorised (e.g. grinding, welding, bending, attaching
parts, bending, attaching parts)!
- The hoist ring must not be exposed to unacceptable temperatures.
- Only original spare parts may be used.
- When transporting dangerous goods, the relevant further regulations must
be observed.
- Load handling attachments must be stored in such a way that they are
protected from damage and do not pose any danger.
- In case of malfunctions, the lifting equipment must be taken out of service
immediately and serviced.
- Load handling attachments must be disposed of properly when they are no
longer needed.
Attention: Any environmentally hazardous substances (e.g. grease and
oils) must be disposed of separately.
Inspection and maintenance:
Slings must be inspected regularly before use, e.g. by the user. The slinging
equipment must be inspected regularly before use, e.g. by the user, to ensure
that it is used properly and is in a fault-free condition (e.g. screw fit, severe
corrosion, deformations, etc.).
Defective slings must not be used. They must be at least once a year, taking
into account the relevant standards and and guidelines of the Employer's Lia-
bility Insurance Association (e.g. BGR 500) by a competent person.
Every 3 years, lifting gear must be tested for cracks using appropriate testing
equipment and by a competent person. The user must observe the results of
the risk assessment in accordance with the Ordinance on Industrial Safety and
Health. The time period is shortened if the products are exposed to critical
operating conditions. Records of the Records of the inspections must be kept.
The test coefficient (see EU Directive 2006/42/EC point 4.4.1) is specified by
the relevant standards and corresponds to 2.5 of the load-bearing capacity
with a safety factor of 4.
Caution: Failure to comply will invalidate the operating permit.
User Manual
Application
The number and arrangement of the host rings on the load must be chosen
so that the load is safely supported and cannot change its position
unpredictably during transport. The shackle/D-ring of the hoist rings must be
properly aligned in the direction of the force application and freely movable.
Use at a slinging angle of >90° is permissible if the shackle/D-ring or suspended
slinging equipment is not supported either on the load or on the slinging point.
The load capacity when used at > 90° is equal to the load capacity at 90° (see
table 1), provided that the load is distributed symmetrically.
The ACTEK SHR hoist ring is not suitable for continuous rotational movement
under load. In the case of rotational use under 90° and full load, increased
wear and premature failure must be expected.
General installation instructions
The hoist rings must be easily recognisable on the load (e.g. colour-
marking). The position of the anchorage point on the load must be such that
a flat supporting surface is suitable for absorbing the expected force.
This bearing surface must at least correspond to the full diameter (H or A) of
the hoist ring body used and the threaded hole must be at right angles to the
bearing surface. The threaded hole must be countersunk.
The following applies in principle to screwable anchor points:
Check the screw connection for correct screw size, thread size and screw-in
length. Special threads (not listed in the catalogue) are sometimes additionally
marked with the thread designation on the underside of the hoist ring. For
blind holes, the thread depth at the load must be at least 1.1 times the
screw-in length (e).
As a minimum screw-in length (e) we recommend:
in steel 1.00 x d*
in cast iron 1.25 x d*, for cast strengths <200 MPa at least 1.5xd*.
in aluminium 2 x d*, in aluminium-magnesium alloy
* d corresponds to the thread size, e.g. M24 = 24 mm
For ACTEK SHR, crack-tested screws of strength class 12.9 must be used.
If ACTEK SHR are secured with nuts, these must correspond to strength class
12 and be crack-tested.
All ACTEK SHR anchor points must be tightened at least hand-tight !
Load capacity and temperature suitability
The hoist rings are marked with the corresponding load capacity and listed in
tabular and graphic form for the corresponding nominal size in the technical
data sheet. These load capacities must not be exceeded. In the case of
asymmetrical load distribution, the load capacities for the 2- to 4-leg
attachment types apply as for 1-leg at an angle of inclination of 90°. This
corresponds to the load capacity indication on the attachment point.
After use above plus 200°C, the load capacity must be permanently reduced
for further use according to the adjacent table. Accelerated wear of the bearing
is possible in this case and must be monitored by the user.
