Permitted center of gravity on the workpiece carrier
The position of the center of gravity of the load must be taken into account to be
able to absorb acceleration forces when separating or altering direction (curves,
change to transverse direction of transport).
In the arrangement of supports and workpieces on the WT (= workpiece carrier) it
must be ensured that the center of gravity of the loaded WT lies within the area ⅓
of the length, respectively of the width, around the center of the WT. The maximum
height of the center of gravity above the level of transport should not exceed ½ of
the WT

Center of gravity on the workpiece carrier
In general we recommend:
• to load the workpiece carrier as centrally as possible.
• do not let the loading center of gravity exceed in height h
S
½ b
WT
(with b
WT
≤ l
WT
).
Failure to comply with this requirement can compromise the conveyor safety
particularly at higher conveyor speeds.
Maximum mass moment of inertia see “Mass moment of inertia” on page 51.
9.1.5 Environmental
infl uences
• Resistant to many conventional substances used in the manufacturing sector, such
as water, oil, grease, and detergents. If you are unsure about resistance against
certain chemicals such as test oil, doped oils, aggressive detergents, solvents,
or brake fl uid, we recommend that you consult with your specialized Rexroth
representative.
• Avoid prolonged contact with highly acidic or alkaline reacting substances
• Wear can increase signifi cantly in the case of contamination with abrasive media in
the environment in particular; these include sands and silicates from construction
work, for example, as well as from processes on the transfer system (e.g. welding
beads, pumice dust, shards of glass, or loose and easily lost items). Under such
conditions the maintenance intervals should be signifi cantly reduced.
