The load to be lifted over the load shackles of the levelling
supports is 100 kN. This is distributed to the four corners of 25
kN each. Due to possible irregularities in load distribution, this
is defined as 30 kN.

9.2 Test criteria
Observe and check the following points at regular intervals,
after installation and after special occurrences:
– Make sure that the screws are tight.
– Completeness of the anchor point
– Complete, legible load-bearing capacity information
– Deformations on supporting parts such as base body, sus-
pension bracket and screw
– mechanical damage such as strong notches
– Cross-sectional changes due to wear > 10%
– intense corrosion
– Function and damage of screws, nuts and screw threads
– easy, jolt-free rotation of the load support must be ensured
10. INspeCTIoN
The equipment must be inspected in accordance with the con-
ditions of use and the operating conditions latest after 50 lifting
procedures at least once per year by an authorised person
per TRBS 1203 (Technical expert) (testing per BetrSichV, §10,
sect.2 represents implementation of EC Directives 89/391/EEC
and 2009/104/EC and the annual occupational safety inspec-
tion per DGUV-V 54, §23, sect. 2 and DGUV-G 309-007).
These inspections must be documented:
– Before commissioning.
– After significant alterations before recommissioning.
– Latest after 50 lifting procedures.
– At least once per year.
– In the event of unusual occurrences arising that could have
detrimental effects on the safety of the winch (extraordinary
tests, e.g. after a long period of inactivity, accidents, natural
events).
– After repair works that could have an influence on the safety
of the winch.
Technical experts are persons, who have sufficient knowledge
based on their specialist training and experience, in the areas of
winches, lift and pull systems and the relevant official occupa-
tional health and safety rules, accident prevention regulations,
guidelines and generally accepted engineering rules (e.g. EN
standards), to evaluate the operational safety of winches, and
lift and pull systems.
Technical experts are to be nominated by the operator of the
equipment. Performance of the annual occupational safety
inspection as well as the training required to obtain the afore-
mentioned knowledge and skills can be provided by haacon
hebetechnik.
In
every 10th inspection
, at the latest however,
after 10
years
, a major overhaul of the leveling device must occur. In
this process, the leveling device will be disassembled and the
condition of all components has to be examined. Operational
worn components will be substituted, wear parts (bearings,
sealings...) and components relevant for safety have to be
exchanged in every case. We recommend to charge haacon
hebetechnik gmbh with the conduction of this major overhaul.
This inspection may be carried out only by people who are
authorised by the manufacturer haacon hebetechnik gmbh
and who are trained in dealing with this leveling device and its
components.
