APPENDIX “C” FOR LD-4EF DRILL
Air noise
(Directive
2006/42/EC
, Annexe 1, point 1.7.4.2, letter u)
–
The continuous equivalent weighted level (A)
of noise pressure at the working place L
pA
is equal to ....................................................... 84,7 dB (A)
– The maximum value of instantaneous weighted noise
pressure C at the working place L
pCPeak
is lower than ............................................................130 dB (C)
– The level of noise force produced by the machine L
WA
is equal to ........................................................................................................................................... 93,4 dB (A)
Protection of operators against risks of exposure to noise during work.
Cembre
drill type
LD-4EF,
is designed and constructed according to EEC directives
80/1107 and 86/188 relating to the protection of operators against risks arising from exposure
to chemical, physical and biological agents during work, and with particular regard to the risk
of exposure to noise.
This has enabled a range of drills to be manufactured for drilling rails and track equipment, at
reduced noise level.
The degree of exposure of an operators to noise produced from this equipment depends on the
duration of the loading times and the intervals between exposures, and finally on the number
of holes made within the space of one working day.
For example, an operator using the drill correctly for making holes 36 mm in diam., with a type
RCV 360 broach cutter on rails classified as UIC 60, quality 900, producing up to 150 holes/day,
the daily personal exposure to noise, due solely to the use of the drill, is less than 80 dB (A); under
similar conditions producing 300 holes/day, the daily exposure to noise would be 82.2 dB(A).
Since noise levels vary according to the many different operating conditions,
Cembre
engineers
are available to give further details on the correct use of the drills.
Risks due to vibration
(Directive
2006/42/EC
, Annexe 1, point 2.2.1.1)
The weighted root mean square acceleration value to which the arms of an operator are subjected
when using the drill machine does not exceed 2,5 m/s
2.
