QAY220 All Terrain Crane Operation Manual
1-4
If the crane operator does not possess
all necessary and required information,
it may prove impossible to carry out the
intended work, or he may be tempted to
improvise and accidents may be resulted.
As well as a fully functioning crane and
well qualified personnel, operational planning is
an important precondition for safe and reliable
crane operation.
The crane operator must be in possession
of or procure all the necessary information
before starting the crane operation, especially:
1. Natural condition of working site, such
as temperature and wind speed;
2. Site location (journey distance);
3. Route to be driven;
4. Height and side clearances;
5. Electrical overhead wires (complete with
voltage data);
6. Space requirements at the operating site;
7. Movement and operation restrictions due to
surrounding structures;
8. Weight and dimension of load(s) to be
lifted
9. Required lifting height and radius
10. Load-bearing capacity of soil or surface
to be operated upon
The crane operator can then use this
information to decide on the correct crane
operating equipment: hook blocks, jib, auxiliary
winch and super lifting device, as well as
counterweight, wood blocks and tools, etc.
