CMC S19N - 4.2 Safety distances; 4.3 Transport, storage and packaging

MAN.219 Rev.8 ENG - Use and maintenance manual S19N page 19 of 71
Table 1: Beaufort wind scale.
We recommend the use of an anemometer, to determine direction
and speed of wind.
Any addition that increases the wind load on the MEWP, such
as warning signs, is prohibited.
4.2 Safety distances 
Below there are the safety distances to be kept by qualified staff (alternat-
ing current):
Voltage field of electric line
Minimum safety distance
Up to 300 V
Avoid contact
300 V < x > 750 V
1 ft. 0 in. (30,5 cm)
750 V < x > 2 kV
1 ft. 6 in. (46 cm)
2 kV, < x > 15 kV
2 ft. 0 in. (61 cm)
15 kV < x > 37 kV
3 ft. 0 in. (91 cm)
37 kV < x > 87.5 kV
3 ft. 6 in. (107 cm)
87.5 kV < x > 121 kV
4 ft. 0 in. (122 cm)
121 kV < x > 140 kV
4 ft. 6 in. (137 cm)
In any case, do’tn touch the electric lines.
4.3 Transport, storage and packaging
To load/unload the platform, it is possible to use a travelling crane or a
forklift of adequate capacity. For this operation, sling the MEWP by the at-
tacks on the outriggers and on the chassis or use the inserts for the forks
(Picture 12).
