3-34 ZCC1100H Crawler Crane
3.7 Underground cables
With special equipment, the crane can also be used for underground working.
3.7.1 In underground working, it is possible to damage:
a) Underground electric cables
b) Gas pipes
c) Telephone, TV, and data cables
d) Sewage pipes, district heating supply pipes, etc.
WARNING
(1) If a live underground cable is damaged, lives are at risk from electric shock.
(2) There is an extreme danger of explosion and fire in the vicinity of a damaged gas
pipe.
Measures to be taken during operational planning:
The construction company doing the work is responsible for gathering accurate information
about possible underground cables within the working area of the equipment so that work can
be done safely:
a) Obtain relevant information from the relevant utility companies.
b) Examine the "as completed" plans of:
1) Utility companies (electricity, gas and water)
2) Cable users (telecom companies, factories, transport companies)
3) Building authorities.
c) Only use the latest and effective plans.
d) If there are any deviations or extensions to a project, initiate new inquiries.
e) If in doubt, localize the underground cables around the site using a locating device.
f) The relevant utility companies, cable users and public authorities:
–
Must be informed in good time about the start of the work.
–
Must be asked for written approval for the civil engineering work to be done.
g) When several construction companies are involved, their activities must be coordinated. All
companies must have the same up-to-date information on underground pipes, etc. on the
construction site.
3.7.2 Safety precautions and protective measures when operating the
equipment near underground cables
a) Do not start work until you have obtained all the approvals from the utility companies and
the cable users.
b) The equipment operator must obtain all relevant information about the exact location of all
underground cables before starting work. These plans must be readily accessible at the
construction site.
For reference only.
Operators manual should be consulted and adhered to.
