DANGER
Lifting people with a crane is never allowed unless it is a MEWP crane. When
working in a personnel basket, both feet must have contact with the floor of the
basket. Standing on boxes or ladders in the basket can lead to injury or death.
3.3.1. Noise declaration
The following values for emitted noise may be taken as general and conservative values for
ordinary installations of loader cranes on normal diesel engine powered trucks. Declared dual-
number noise emission values in accordance with ISO 4871:
• Emitted A-weighted sound power level for basic loader cranes in accordance with ISO 3744:
LwA = 103 dB (Uncertainty: KwA = 2 dB).
• Emitted A-weighted sound power level for loader cranes with hoist in accordance with ISO 3744:
LwA = 107 dB (Uncertainty: KwA = 2 dB).
• A-weighted sound pressure level at loader crane control stations in accordance with ISO 11201:
LpA = 95 dB (Uncertainty: KpA = 4 dB).
Particular installations can be quieter, in which case a post installation noise measurement in
accordance with clause 6.3 of EN 12999 may be used to prove this.
