TENSION PULLEY WITH HORIZONTAL COUNTERWEIGHT
• Mount the mounting support at about 450 mm (ap-
prox. value, fig. 3) on the bottom of the shaft.
• Hold the counterweight, until it is in an oblique posi-
tion (fig. 3).
• In the presence of a brake mechanism acting up-
wards, mount the second rope-end to the rope-an-
chor 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 counterweight should take a slighty
upward angled position (fig. 3).
TENSION PULLEY WITH VERTICAL COUNTERWEIGHT
• Mount the leading plate of the
counterweight to achieve per-
fect alignment between the
pulley of the overspeed gover-
nor and the pulley of the ten-
sion weight (fig. 4).
• Hold the counterweight, until it
reaches a height of about 120
mm from the bottom of the
shaft (approx.value) (fig. 4).
