GUIDE RAIL MOUNTED TENSION PULLEY:
Models with the horizontal counterweight mount the mounting support at
●
about 260mm (approximate value: Fig. 4) from the bottom of the shaft.
Models with the vertical counterweight mount the mounting support at
●
about 460mm (approximate value: Fig. 5) from the bottom of the shaft.
Support the counterweight of the models with horizontal counterweight until
●
it is in an oblique position (Fig. 4).
In the model with vertical counterweight keep a distance of about 100mm
●
between counterweight and bottom of the shaft (Fig. 5).
In the presence of a brake mechanism acting upwards, mount the
●
second rope-end to the rope-anchor of the brake device.
or:
Supply the second rope-end with the rope-anchor and attach it to the safety
●
gear.
Remove the support in order to stretch the rope.
●
If the assembly has been properly carried
out, the horizontal counterweight should take
a slightly upward angled position (fig. 4).
PIT MOUNTED PULLEY:
Mount the leading plate of the counterweight to achieve perfect alignment
●
between the pulley of the overspeed governor and the pulley of the tension
weight (Fig. 6).
Hold the counterweight, until it reaches a height of about 45 mm from the
●
bottom of the shaft (approx. value) (Fig. 6).
