ASSEMBLY
For all the assembly works in the engine room or in the elevator shaft, it should be made clear that:
The entrance into the assembly area, resp. the execution of all works can be carried out only by skil-
led workers.
In particular, the following safety measures should be respected:
- fix the anti-fall protection device (working plattorm, for safety of the persons);
- cover the hole in the floor;
- secure the assembly tools and other objects to avoid unintentional falls;
- in case the works have to be executed in the elevator shatt, lock the doorways and attach the appro-
priate warning sign.
2.1 ASSEMBLY OF THE OVERSPEED GOVERNOR
2.1.1 ASSEMlBLY IN THE ENGINE ROOM
PREPARATION
The assembly of the overspeed governor occurs either directly on the floor in the engine room or on
a support.
Floor and support must resist to a pressure of 25 kN
In the elevators in conformity to EN 81, the passing openings of the rope should be kept as small
as possible and must be fitted with safety rings 50 mm high.
For elevators in conformity to TRA, the same procedure is recommended.
Before the assembly takes place, it is necessary to fix an adequate safety ring on the floor.
If, after the assembly on the cement, a stone floor is laid down, its height should be considered (fig. 1).
