2.6 Securing the drive and safety wire
Fig. 13 Drive wire contra weight2.6.1 Drive wire contra weight
An 11 kg weight is mounted approximately 300mm
below the floor on the drive wire. Excess wire is
coiled with at least 3 strips (See Fig. 13).
CAUTION!
DO NOT fix the traction wire below
the bottom platform.
The traction wire MUST be hanging
freely so it can rotate.
2.6.2 Safety wire method 1:
Wedge anchor with spring
As in point 2.3.1 above the wire is fastened
using a rigging screw with spring (See Fig. 13a).
Mounting the safety wire without the spring will
cause the safety brake to block frequently. Excess
wire is coiled with at least 3 strips.
