INSTRUCTIONS: PQ-4000-UD
Cod: DYN 11.01.08

Revision: 08
Storage humidity: 15 - 85% without condensation.
The safety gears' packaging should be clean and dry, so that they can be clearly identified.
It is not permitted to place constant or unbalanced loads on a package, which may cause the package to be
bent, or to allow products to be stacked one on top of the other. When stacking products or packages, the
storage height should take into account their load and stability.
If the criteria established for proper maintenance are observed, the safety gears may have the same service
life as the rest of the installation's fixed elements provided that their proper functioning is ensured and
controlled. The element's service life is not affected by grease, dust or dirt due to the shaft's condition or to
environmental conditions differing from those stated in this manual.

5.1 UCM SYSTEM'S PRELIMINARY DESIGN.
According to EN 81:20 and EN 81:50, lifts should be equipped with means for stopping uncontrolled car
movement (UCM). These means should detect UCM and stop the car. This stop must occur at a maximum
distance below 1 m (among other requirements).
The safety gears may be used as a braking device for stopping the uncontrolled movement.
The values for the safety gear's braking distance may be calculated beforehand, but several installation
parameters must be taken into account. The more information that is known about the physical elements that
make up the system, the closer the theoretical value will be to the actual value.
These are theoretical values and may only be used in the system's preliminary design. The installation's
compliance with the standard requirements is pending.
5.2 SAFETY GEAR BRAKING DISTANCE CALCULATION
The detailed calculations can be found in the manual: DYN 62.04 – UCM. Braking distance.
