Overloading of Cranes
Hisham
1. Should a crawler or mobile crane be overloaded when tested?
2. Should the Data Logger on the cranes be locked by the manufacturer
or should the user of the crane have access to it.
3. What is the criteria of working at heights and at what point is
working above the ground considered working at height?
4.Should a rigging or operator certificate have an expiry date and if
yes what is the validity person?
5. I noticed the many mobile cranes are working and lifting with no
outriggers mats under the outrigger. I like to know if this is
acceptable (which i believe it is totally wrong) and if it is not
acceptable what should be done to stop such activities.

1 My own view is yes they should be tested but would prefer to use the
words Proof Load Test not overload test. Until such times as
mandatory strip down and NDT inspections are built in to the
maintenance program then I can see no other way of proving the
integrity of the machine.
2 I am not sure what the Data Logger actually achieves other than
after a significant event or as a maintenance tool. As far as who as
rights to the information then this could easily be set to different
levels, with the Manufacturer and or legal bodies having a higher
level of access.

1. Should a crawler or mobile crane be overloaded when tested?
A) Cranes should never be used in-excess of the correct duty chart for
that configuration; the only exceptions to this rule are;
Following a major repair or replacement, then this test is carried out
under the direct supervision and control of the relevant Crane
Manufacture; all other tests are carried out in accordance
with BS71721 Part 2 Testing & Examination & LOLER Regs
2. Should the Data Logger on the cranes be locked by the manufacturer?
or should the user of the crane have access to it.
A) The Data logger is part of the machine, as such it belongs to
whoever owns the machine, with that in mind each crane Data Logger
requires a special Computer Programme which only the individual
Manufacture holds (It is expensive to purchase) so with that in mind
you can only really download the logger with the assistance of the
manufacture (plus a small fee each time)
3. What is the criteria of working at heights and at what point is
working above the ground considered working at height?
A) The answer to this question is purely dependant on where you are
working, many sites in the Middle East work to there own site rules,
some use the UK Legislation of "any distance above or below ground",
some use the European Standard of 2 meters, some sites will work to
the US standards 29 CFR 1926 OSHA Construction Industry Regs which is
6 feet (1.8 m)
Recommend that your company should have own standard and train the
workforce accordingly to include correct method of wearing the
Harness.
4.Should a rigging or operator certificate have an expiry date and if
yes what is the validity person?
A) Dependant upon Company / Policy, UK standard 5 years for Trained
Competent individual, or 3 years for Trained individual.
5. I noticed the many mobile cranes are working and lifting with no
outriggers mats under the outrigger. I like to know if this is
acceptable (which i believe it is totally wrong) and if it is not
acceptable what should be done to stop such activities.
A) The Crane Owners Company Policy or site Policy, Crane Manufactures
do not provide Nylocast, Steel or Timber load spreader mats as
standard with the machines, this is down to the Owner of the Machine,
also in UK the client / site owner has the responsibility to ensure
that the ground is sufficiently compacted to withstand the Outrigger
Point Loadings required, dependant on the loads and type of machine to
be used.
