Mechanical Installation
The VG OSG should be installed using the mounting feet provided; other
mounting options are available on request, which will facilitate accurate
alignment and adjustment so that it is parallel and square to the governor rope
/ pit tension weight. The fixings used must be capable of withstanding the static
braking force calculated by the application program with an appropriate margin
of safety.
The VG OSG should now be roped with an appropriate 8mm governor rope with
a Tensile Grade of between 1570N/mm² to 1770N/mm². You must ensure that
the rope follows the path shown in the diagram below and runs squarely in the
pulley groove.
