The table below shows the load-bearing capacity of the ground split up by ground type.
Refer to the data contained in the specific tables of each model (chapter 2, TECHNICAL FEATURES OF STANDARD MACHINES)
to obtain the figure relating to the max pressure on the ground caused by the single wheel.
Using the machine is forbidden if the max ground pressure per wheel is higher than the bearing capacity of
the specific type of ground on which the machine is to be used.

Should you have any doubts, verify the load-bearing capacity with specific tests.
In case of constructed surfaces (concrete floors, bridges, etc.) the load-bearing capacity must be provided by the builder.
3.3.6. High-voltage power lines
The machine is not electrically insulated and is not protected in case of contact with or vicinity to power lines.
According to the applicable laws and the following table a minimum distance from the power lines must be kept

3.4. Dangerous situations and/or accidents
▪ If, during Preliminary Operation Checks or when using the machine, the operator discovers a defect that could produce a
hazardous situation, the machine must be placed in safety condition (isolate it and affix a notice) and the employer must be
notified about the fault.
▪ If, during use, an accident occurs, without injuries to the operators, caused by operating errors (e.g., collisions) or any structural
yielding, the machine must be placed in safety condition (isolate it and affix a notice) and the employer must be notified about
the fault.
▪ In case of an accident with injuries to one or more operators, the operator on the ground (or on a platform not involved in the
accident) must:
▪ Seek help immediately
▪ Perform the operation to return the platform to the ground only if he is certain this will not make the situation
worse.
▪ Place the machine in safety condition and notify the fault to the employer.
