2.2 ASSEMBLY OF THIE ROPE OF THE OVERSPEED GOVERNOR /
TENSION WEIGHT WITH COUNTERWEIGHT
A technically perfect operation of the overspeed governor is only possible with a correct assembly of the gover-
nor rope itself and of the tension weight with counterweight.
While determining at which height the tension weight with counterweight has to be mounted, it must be made
clear that:
- in no case, the counterweight must touch the floor (fig. 1);
- when the framework of the elevator car reaches its lowest position (by the compressed buffer), the
lower rope anchor of the rope and the downward remaining rope-end must not meet the pulley of
the tension weight.
• Cut the overspeed governor rope sufficiently and lay it down on the rope pulley of the tension weight with
counterweight.
• Supply the first rope-end with the rope-anchor (fig. 1) and attach it to the safety gear.
Fig. 1
• Let the second piece of rope drop inside the elevator shaft.
• Mount the mouting support at about 450 mm (approx. value, fig. 1 ) on the bottom of the shaft.
• Hold the counterweight, until it is in an oblique position (fig. 2).
• 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 counterweight should take a slighty upward
angled position (fig. 3).
