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 UNE‐EN 81‐1:1998+A3:2009, 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.
