Use and Maintenance Manual - R13 R17 Series Page 28
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 pressure on the ground per wheel is above the load-bearing
capacity of the specific type of ground on which the machine is to be used.
TYPE OF GROUND BEARING CAPACITY IN Kg/ cm²
Non compact filling earth 0 – 1
Mud, peat, etc. 0
Sand 1.5
Gravel 2
Friable earth 0
Soft earth 0.4
Rigid earth 1
Semi-solid earth 2
Solid earth 4
Rock 15 - 30
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-tension lines
The machine is not electrically insulated and is not protected in case of contact with or vicinity to power lines.
A minimum distance must be kept from the power lines according to applicable laws and the following table
Type of power lines Voltage (KV) Minimum distance (m)
Light poles
<1 3
1-10 3.5
10 - 15 3.5
15 - 132 5
132 - 220 7
220 - 380 7
High-voltage pylons >380 15
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, with injury 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.
