EVALUATE THE CONSISTENCY OF THE GROUND
The ground on which the telehandler is positioned must be
able to support the machine and its maximum load.
- ATTENTION -
If the ground under the telehandler collapses,
the machine may roll over.
- Comply with the following indications to avoid overtur-
ning the machine:
Ask your employer (works manager, construction assi-
stant) if there may be any hidden cavities below the sta-
bilisers (pipelines, wells, old cisterns, basement ceilings,
manure pits, etc.)
The operator must evaluate the consistency of the
ground, using the tables and graphs provided. In case
of doubt, consult the civil engineer present on the site
or seek the advice of an external engineer.
Depending on the type of ground and its geomorphologic
characteristics, the subsoil can only support a limited
quantity of stress. The table in fig.3/B indicates the allowed
surface pressure underneath the telehandler stabilisers.
On the basis of the “Maximum pressure exercised on the
ground by the stabiliser feet” Table (fig.2/B) and the data
extracted from the table in fig.3/B, “Allowed surface pres-
sure on varying ground types”, it is possible to deduct the
necessary support surface (increased support bases).
- ATTENTION -
Always seek the advice of a civil engineer for the most
reliable and exact evaluation possible of the ground
where you intend to work and the dimensions of the
support plates.
- ATTENTION -
On request, DIECI can provide enlarged base supports.
