TELLURE ROTA
Static load
Maximum load (expressed in daN) that a mo-
tionless (stationary) wheel can support with-
out generating any permanent deformation
that may reduce operating efficiency.
Dynamic carrying capacity
Maximum load value (expressed in daN) that
can be supported by a moving wheel.
This value is determined in compliance with
Standard
ISO
22883-22884
for
industrial
use and ISO 22879-22880 for civil and domestic use.
See page 42-43 for the test conditions.

The safety and easy handling of a trolley depends on choosing the most suita-
ble wheel, therefore, it is recommended to consider the following factors:
1. NATURE AND CONDITION OF THE FLOOR
The type of floor and the presence of any obstacles will have an influence on the
thrust/traction force required to move the trolley, on the transmission of vibra-
tions and wear of the wheel:
•
Extremely thick wheels with soft tread and large diameter are normally cho-
sen for uneven floors or with obstacles;
•
Wheels with a more sturdy tread are normally chosen for smooth floors and
heavy loads.
For each series, the catalogue shows the floor for which a wheel is suitable:
2. ENVIRONMENT OF USE
The wheel and bracket materials may or may not be suitable for use in aggres-
sive environments: extreme temperatures, humidity, acids, solvents, bases and
hydrocarbons.
The table on page 36 shows the compatibility with a detailed list of chemical substances.
The table on page 38 shows the carrying capacity reduction upon temperature variation.
3. MAGNITUDE AND NATURE OF THE LOAD
The weight of the load, its nature (solid or liquid) and the tare of the trolley de-
termine the minimum carrying capacity the wheel must have to guarantee safe
handling.
