SET-UP AND INSTALLATION PROCEDURES RT530E-2 OPERATOR’S MANUAL

4. Inspect mechanical and electrical installation of power
measurement sockets on the lattice extension (if
present).
Check Hoist limit switch warning light and acoustic alarm as
follows:
1. Manually raise weight fitted on the A2B switch. As soon
as weight is raised, the acoustic alarm should sound and
A2B switch warning should display.
2. Using the main hoist, pull hook block slowly against the
A2B switch weight. As soon as the hook block raises the
weight, the acoustic alarm should be triggered, the A2B
switch warning should display, and the main hoist should
switch off. Lower the hook block slightly to eliminate this
condition.
3. Slowly lower the boom to bring about a potential hoist
limit situation. As soon as the hook block raises the
weight, the acoustic alarm should sound, the A2B switch
warning should display, and the luffing gear should
switch off. Lower the hook block slightly to eliminate this
condition.
4. Slowly extend (telescope out) the boom to bring about a
potential hoist limit situation. As soon as the hook block
raises the weight, the acoustic alarm should sound, the
A2B switch warning should display, and the telescoping
function should switch off. Lower the hook block slightly
to eliminate this condition.
5. If crane is equipped with a main boom or lattice
extension, the inspection procedure must be repeated
for the A2B switch of the extension/top section.
6. Check display of main boom length agrees with actual
boom length.
7. Check display of main boom angle agrees with actual
boom angles.
8. Check display of the crane operating radius agrees with
the actual radius.
9. Check load display by lifting a load of known weight.
Load display accuracy must be within the tolerance
range.
WARNING
The following tests must be performed with care to
prevent personnel injury or crane damage. Proper
functioning of the CCS requires successful completion of
these tests before starting work.
If the operator cannot see the hook block approaching the
pulley head, this task must be assigned to an assistant
(slinger).
The crane operator must be prepared to stop the crane
immediately if the CCS is not working correctly, i.e. when
warning indicators do not display, the acoustic alarm does
not sound, and crane movements such as raising,
extending and luffing are not disabled.
WARNING
If warning indicators and audible alarm do not function as
described and crane movements are not switched off, the
system is not working properly. The malfunction must be
corrected before starting work.
