In production and distribution systems demands on logistic support systems are
becoming higher and higher. The transportation system becomes heavy loaded.
This means that not only AGV's, roll-conveyors and moving belt conveyors,
but also overhead conveyors must be considered for supporting an
automatic system. Overhead conveyors consist of a trolley, constructed a
few metres above the floor on a rail. The trolley carries the load, which
hangs below the trolley. It is possible to build a route, so that the
loads can be transported to different stations.
Overhead conveyors can be divided into four groups, hand-, chain-,
power & free and electric overhead conveyors. These groups
distinct from eachother by the way the trolleys are driven. The names are
already explaining it: hand overhead conveyors by hand; chain and
power&free by chain; and electric overhead conveyors by an electric motor
on the trolley.
The hand overhead conveyor is the basic overhead conveyor system. The profiles,
used by the handconveyor, are also used by the chain conveyors and the
power & free conveyors.
Chain overhead conveyors have in principle a permanent route and a central
driving gear of all trolleys. The chain, to which all the trolleys are
connected, formes a closed circuit. This means that no joints and elevators
are possible. Rather the other groups have these possibilities. This
makes these groups more flexible and they have more facilities.
Power & free is a combination of a chain overhead conveyor and a
hand overhead conveyor. This combination makes a deconnectable chain overhead
conveyor. The chain provides the driving, just as with the chain conveyor,
however the trolleys and the chain are not connected. The trolleys are driven
by ridge beams so they can travel freely in freeline under the chain, just as
with the hand overhead conveyor.
In electric overhead conveyor systems the trolleys have their own driving
engine. This means that the shape of the profile is different. The trolley is
supplied and directed through the electric rail. A fully automatic system is
possible, because of the fact that each trolley is separately directed. The
speed of the electric overhead conveyor is much higher than the speed of the
other overhead conveyors.
