Care, maintenance and repair
Visual inspection and maintenance
Checking the load cable for wear
The wire rope hoist is subjected to periodic mainte-
nance and supervision. In many cases is the procedure
of monitoring regulated in norms and directives (e.g.
DIN 15020 paper 2 ,, principles of wire rope hoist, moni-
toring and use“).
The typical evaluation criteria described in norms with
regard the wire rope discard in case of e.g. wire break,
wire break nests, strand breakages, structural changes,
mechanical wear or corrosion can be assessed by ap-
propriate qualified specialists, which are trained in
maintenance and assessment of cranes.
Continuous monitoring of the hoist in compliance with
DIN 685 Part 5 and UVV BGV D8 Section 27 (VBG 8
Section 27) is a compulsory requirement. The load ca-
ble should be inspected before starting up and under
normal operating conditions after about 200 operating
hours or 10,000 load cycles, under heavy operating
conditions at shorter intervals.
Particular checks should be made on the links, espe-
cially contact points, for wear, deformation, wire breaks,
structural changes, corrosion and other damage.
The cable guide should be checked when changing the
cable and replaced if necessary.

Section 23) by a specialist before commissioning and
following major changes.
Testing in compliance with BGV D6 Section 25 (VBG 9
Section 25) by an authorised expert before commission-
ing and following any major changes.
Annual repeat testing of equipment, crane and support-
ing structures by a specialist. Where equipment is sub-
ject to heavy operational conditions (e.g. frequent oper-
ation with a full load, dusty or aggressive environment,
frequent stopping, long operation time) the testing inter-
vals should be reduced.
- With regard to testing cranes, experts are exclu-
sively TÜV experts or experts authorised by pro-
fessional bodies or associations.
- Specialists are customer service installers em-
ployed by the manufacturer or specially trained
specialist personnel.
Evidence of wire rope hoist testing should be kept in an
inspection log book.
Testing is generally a visual and functional test. It in-
cludes an inspection of the condition of the components
and equipment, the completeness and functionality of
the safety equipment and the completeness of the log
book.
