replaces the operation instructions and safety manuals.
4.1.1 General points to consider when using placing booms
1. The placing boom is used on a site to relieve the crane from concreting
operations.
2. Consideration must be given to the time the installation of the boom requires.
3. Full supervision must be given during the operations; the supervisor must be
experienced in the task.
4. Full and complete check systems need to be used to monitor the installation
and commissioning of the machine.
5. Operators must be trained to maintain the equipment to a reasonable standard.
6. Attention must be paid to the condition of the machine while on site, it must be
inspected regularly by a competent person and a report placed in the safety file.
7. The site electrician should inspect, on a regular basis, the power cable and
installed sockets, at both the control panel on the boom and the circuit breaker
at the mains supply.
8. If the boom is to be used on its own generator, the recommended size to use is
75kVA.
9. On a SPB32 placing boom, the 22kW electric motor requires a start up current
of 84 Amps and a running current of 42 Amps.
10. Safety is paramount and to this end all assembly personnel need to be trained
and certified in the safe and correct installation of placing booms.
11. Cleaning out of the boom should be considered and the use of the water wash
out system is recommended. This is cost effective and the concrete in the line is
pumped to the placing point and with continued practice this system is safer.
