ALMACRAWLER JIBBI Series User Manual

PAGE74
The following table shows the indicative bearing capacity of the soil according to the type of soil.
Compare the bearing capacity of the ground with the specific pressure data calculated with the method
just described, to understand if the ground is able to withstand the pressure generated by the machine.
The values in the table are indicative, therefore in case of doubts the bearing capacity of the ground
must be ascertained with specific tests.
In the case of artefacts (for example: concrete floors, bridges, etc.) the bearing capacity must be
requested from the manufacturer of the artefact.

It is forbidden to use the machine if the maximum pressure generated on the ground is higher than the
permitted bearing capacity value indicated in the table.
3.2.5.2 Ground inclination.
Always, before using the machine, the operator must check that the floor or ground is suitable so as not
to slide the machine due to high slope and / or poor grip. The overall performance of the machine is
automatically reduced when you are working on lands with a longitudinal slope between 5° and 15°.
When facing slopes greater than 5° it is recommended to arrange the machine as shown in fig. B, in the
following image, to obtain maximum work performance in terms of height and lateral outreach.
