e) In transit with no load and boom lowered, the equipment clearance shall be a minimum of
4 feet for voltages less than 50 kV., and 10 feet for voltages over 50 kV., up to and
including 345 kV., and 16 feet for voltages over 345 kV. up to and including 750 kV.
f) Check whether an appropriate operating site has been selected so that the crane
movements can be performed within maximum and minimum working radiuses.
g) Check whether there are obstacles which will hinder required crane operation.
h) The equipment must not be assembled or used unless ground conditions are firm, drained,
and graded to a sufficient extent so that, in conjunction (if necessary) with the use of
supporting materials, the equipment manufacturer’s specifications for adequate support
and degree of level of the equipment are met. The requirement for the ground to be
drained does not apply to marshes/wetlands.
i) Know clearly about the type of crane operation and operating mode.
j) Check the distance between the lifting points and surrounding buildings.
k) Influence of communal facilities on crane operation (including the overhead high/low
voltage lines and underground gas pipes).
l) Movement restrictions due to surrounding structures (e.g. is there another crane nearby in
working).
m) Number, weight, dimensions, material of load(s) to be lifted.
n) Required lifting height and slewing radius.
o) Heights and widths of thoroughfares leading to the site.
p) Check the communication ways adopted by signalman and crane operator.
q) Take appropriate measures to keep people and equipment unconcerned away from the
danger area of the crane.
CAUTION
To master the actual condition of lifting operation accurately and ensure safe operation,
the safety measures mentioned above should be checked and a proper operational
planning should be carried out.
DANGER
(1) Due to lack of necessary safe facilities, this crane is not permitted to work at those
sites where the combustible and explosive objects exist such as gas station, oil-gas
lines, corrosive objects etc. Additionally, the crane is prohibited to transport the
combustible and explosive objects.
(2) This crane is not allowed to perform underground operation.
For reference only.
Operators manual should be consulted and adhered to.
