Slewing bearings for Mining excavator , Handling cranes , Ship loader , Bucket wheel excavator and Stacker/reclaimer.
The term 'mining excavator' refers to the largest excavators
with a bucket capacity of over 50 tons of material weight. These
machines are mainly used in mines for the extraction of coal, ores,
and other raw materials. The machine's high level of mobility is
its advantage over bucket excavators. This is achieved by means
of the bearing, which ensures a connection between the upper
structure and chassis of the excavator, enabling it to rotate around
the whole work area.
Port operations, handling and shipyard cranes offer essential support in transporting products, goods and parts. These cranes are
often rail-mounted and characterised by their reliable technology
and high durability. Since bearings made by thyssenkrupp rothe
erde can withstand the toughest demands and operate under
extreme load conditions, they have already been used as loading
and shipyard cranes around the world.
Ship loaders and ship unloaders are important in ensuring the
efficient transportation of bulk goods along the shipping route.
Coal, ores, phosphate, sulphur and fertilisers are fed onto
continuously operational conveyor belts, and deposited into the
vessel to be transported on a cantilever by means of the ship’s
open loading hatch. For the ship to be optimally filled, it has to
be moved under the cantilever. Elaborate manoeuvring can be
avoided if the cantilever’s unloading system is movable.
The stacker/reclaimer is a versatile stockyard machine. Several
types of materials can be stacked in the same stockyard since the
reclaimer is able to move and retrieve the exact material required.
In addition, multiple reclaimers can be installed in one stockyard.
Bucket wheel excavator
The bucket wheel excavator mines bulk material stored at the
end of the conveyor line in a targeted and continuous manner.
The excavator consists of a chassis, a feeder of the materials to
be stacked and a rotatable upper structure with the ejection trailer.
Spoil piles coming from the conveyor belt can be filled again at
another location with a spreader. Slewing bearings made by
thyssenkrupp rothe erde ensure the chassis and the upper
structure are reliably connected. The excavator is a lifting device
for heaped material, which needs to be transported from a stockpile for further processing. The diverse selection of models
ensures all kinds of storage locations are catered to. Since swivel
movements have to be carried out to remove a stockpile, our
slewing bearings of varied dimensions are also put to use here.
