4.2 PRECAUTIONS
It is recommended to keep in mind the following items:
The factory protective covering should be removed from the guide rails. In addition, it should be
checked that there are no other objects, such as screws, brackets, etc. that may interfere with the
safety gear or its driving bar.
It should be visually checked that the safety gears are in working order, that they are not dirty or greasy
inside.
After any inspection or test where the safety gears were tripped, it should be checked that the safety
gears have not been damaged.
It is recommended to perform the tests near the car door to unload the car in order to facilitate
unjamming the safety gears.
The authorised personnel should always take the necessary precautions when tripping any of the
previously installed safety gears.
4.3 MAINTENANCE
Both for maintenance and inspection, the following maintenance operations should be performed after tripping
the safety gears.
4.3.1
LIST OF MAINTENANCE OPERATIONS
Safety gears:
Check that there is no interference between the shoe and the guide rail, nor between the rollers and
the guide rail.
Check the brackets and the clearance between the safety gears and the frame, readjust it if necessary.
Clean any remaining grease, shavings or dust inside the safety gear’s housing.
Check that there is no external element inside the safety gear’s housing.
Check that the rollers spin freely and are not damaged or worn.
Check that the connection between the rollers and the driving bar has not been damaged and spins
freely without being blocked.
Visually check that the safety gears are not damaged in general.
Check that the driving bar is in good condition and that the safety gears are correctly synchronised.
Check that the car’s floor does not have more than a 5% slope in comparison with its normal position.
Check that the governor’s attachment moves correctly and is in good condition.
Check that the safety electrical contact has been correctly assembled and is functioning properly.
Guide rails:
Clean and remove any type of dirt or dust from the guide rails.
Eliminate the marks or burrs caused by tripping the safety gears.
Apply a thin and even layer of lubricating oil, as indicated in item 2.2, section b) of this manual, on the
guide rails.
4.3.2
CORROSION.
All DYNATECH safety gears have anti-corrosion protection. However, it should be regularly checked that the
safety gear’s mobile elements are in perfect working condition; a jamming test will not be required, just a simple
verification that all the parts are moving freely, as well as a visual inspection of the general condition of the
surfaces.
These verifications should be done more regularly, as the maintenance worker considers necessary, when the
installation is in an especially corrosive environment.
4.4 STORAGE AND SERVICE LIFE
The safety gear should be stored in a cool, dry place. It should be protected from excessive lighting. It should
never be exposed to severe weather conditions.
Storage temperature: 5 - 40ºC
Storage humidity: 15 - 85% without condensation.
The safety gears’ packaging should be clean and dry, so that they can be clearly identified.
