2.3 NOISE AND VIBRATION
The airborne noise emission on the SP range of machines does not exceed 79dB(A), measured at a
perpendicular distance of 12 feet, under equivalent continuous A-weighted sound pressure test
conditions. This was based on a Diesel powered machine, working on high throttle, and under load. All
other models will exhibit significantly lower emissions than this figure, dependant on power option. In
normal operation the Vibration level to which the operator is subjected will not exceed a weighted root
mean square acceleration value of 2.5 m/s

2.4 TEST REPORT
All Niftylift machine models are subjected to a comprehensive ‘type test’ which duplicates all
combinations of safe working load (SWL), overload, windage, inertia and pull force to assess the
various safe stability criteria. Self propelled machines are also subjected to kerb and braking tests at
the SWL to satisfy additional ‘worst case’ stability requirements.
Each individual machine is then subjected to static overload tests on flat level ground with 150% of the
SWL, exceeding the requirements of EN280 for power operated MEWPs. Self propelled machines are
also tested at the rated working angle (0º) plus 5º with a test load of 125% of the SWL. Finally, on all
machines, a functional test is performed with 110% of SWL.
All safety devices are checked for correct operation, operating speeds are checked against benchmark
figures and the dynamic functions ensure that all acceleration and deceleration forces are within
acceptable limits. All noted defects are rectified and recorded before the machine is permitted to enter
into service.
