5.3.5 Influence of the wind on the crane operation
A strong wind can overload the crane, so during operations keep under control the wind speed. When
working with full load, the maximum admittable wind speed is 45 km/h (28 mile/h).
When this value is exceeded, any crane operation must be stopped and the crane must be brought to the
rest position. Since the maximum working height of the crane is reasonable, refer to the following table to
evaluate the possible wind effect:

5.4 RULES CONCERNING SAFETY IN THE TRAFFIC
- The machine is an hydraulic crane for lorries and light trucks.The installation on the vehicle must be made
in compliance with the relevant national laws and regulations.
- When traveling on roads and public sites always respect the relevant national laws and regulations.
DANGER
Before traveling on roads,make sure that the crane is folded in rest position. If the crane is open
or lying on vehicle’s body exceeding the overall dimensions allowwed by the highway code,it can
hit bridges,electric power lines or other obstructions.
-Before driving away,make sure that the lever of the pin securing the outrigger’s beam is fully locked.Accidental
slipping out of the outrigger during traveling can result in serious damages. Special care must be taken
when driving nearby crossroads, lever-crossing and subways.
