5.1 Preparations at the workplace
5.1.1 Marking the cuts to be made
The parts to be cut out are usually marked by the client.
If necessary, make dividing cuts to adjust the maximum size and weight of the concrete
blocks to the prevailing conditions (i.e. the lifting capacity of the crane or the maximum
permissible floor loading capacity and size of doors).
5.1.2 Planning the wire guidance system and cutting configuration
Thorough training and experience are the most important prerequisites for optimum
planning of the cutting configuration and wire guidance system.
Long lengths of wire in contact with the object to be cut or cutting in a very flat arc reduce
sawing performance.
The rule of thumb is: Pulley distance H = cutting length L x 0.2.
For a cutting length of 1.5 meters the pulley distance should thus be 0.3 meters
(1.5 m x 0.2 = 0.3 m).
When planning the wire guidance system, make sure that the wire contact length does
not exceed 2 meters.
