AS 1735.10(Int):1998 pdf download.Lifts, escalators and moving walks Part 10: Tests.

Spring return buffers shall be attached to a foundation designed to withstand the forces resulting from the buffer compression,

without appreciable deflection.

3.3.4.2 Airacluneni

Buffers shall be attached, in accordance with the manufacturer’s drawings or by equivalent means, to —

(a) the foundation, for buffers of the spring-return type; or

(b) the under-side of the centre of the test weight. for buffers of the gravity-return type.

3.3.4.3 Position

Buffers shall be positioned centrally with relation to the drop-test weight and in a vertical position which, after being secured

in position, shall not vary from the vertical by more than 1 millimetre per metre of extended buffer length.

3.3.5 Oil

After having beeii installed, the buffer shall be filled with oil to a level not above the highest nor below the lowest gauge

lines. The properties of the oil shall comply with Section 9 of AS 1735.2 as specified on the name plate.

The following procedure shall be followed to ensure that a constant oil level has been established:

(a) After having been fllled with oil in the correct level, the buffer shall he fully compressed at a slow speed.

(b) After having been compressed, the buffer shall be allowed to return to its fully extended position and remain there for not

less than 10 mm.

(c) After the 10-minute period, the oil level shall be checked.
