SCHWING GMBH – Separate Placing Booms SPB 02/2014 13
4.1.2 Safety aspects
When assembling the Schwing separate placing boom system on the octagonal
column accessories, it needs to be recognised that although the system is
designed to be simple to use, the components are of a robust construction and as
such are heavy to handle. A dedicated crane is required for the initial installation.
When these operations are carried out on a site all of the site management needs
to be made aware of the cranes intensive use during the erection.
A banks man must be with the assembly team at all times. It must be realised that
for ease of assembly all the components must be slung level, trying to force the
items together is tiring, awkward and with the close proximity of operatives’ hands
to the connection points, failure to sling items correctly will create a hazard.
The working area needs to be properly cordoned off and clear of any trip hazards.
It needs to be of sufficient size to allow ease of access and egress for the
assembly personnel.
Every operative must wear the required PPE and safety harnesses and fall arrest
equipment must be supplied to those who will be climbing the mast to carry out
final connection.
Precaution should be taken regarding tools that have to be used on the working
platform of the mast, the ladders have safety hoops attached restricting the
person on the ladder from being able to carry any bulky items.
A simple idea is to have rope hanging from the working platform hand rail, (this
should only be during installation) and a tool bag that can be closed, hence the
tools once in the bag are then fastened to the rope and hoisted to the work area.
When used with a heavy duty cross frame, the holding down bolts must be M36
diameter and of 8.8 grade. Schwing can give the correct tensile and compressive
loads and it is then up to the bolt supplier to give the correct torque settings for
these bolts.
