EOT(Electric
Overhead Traveling) crane, this is most common type of overhead crane, found in
most factories. As obvious from name, these cranes are electrically operated by
a control pendant, radio/IR remote pendant or from an operator cabin attached
with the crane itself.
An EOT crane,
commonly called a bridge crane, is a type of crane found in industrial
environments. An EOT crane consists of parallel runways with a traveling bridge
spanning the gap. A hoist, the lifting component of a crane, travels along the
bridge. If the bridge is rigidly supported on two or more legs running on a
fixed rail at ground level, the crane is called a gantry crane (USA, ASME B30
series) or a goliath crane (UK, BS 466).
Unlike mobile or
construction cranes, EOT cranes are typically used for either manufacturing or
maintenance applications, where efficiency or downtime are critical factors.
Application
EOT cranes are
commonly used in the refinement of steel and other metals such as copper and
aluminium. At every step of the manufacturing process, until it leaves a
factory as a finished product, metal is handled by an EOT crane. Raw materials
are poured into a furnace by crane, hot metal is then rolled to specific
thickness and tempered or annealed, and then stored by an EOT crane for
cooling, the finished coils are lifted and loaded onto trucks and trains by EOT
crane, and the fabricator or stamper uses an EOT crane to handle the steel in
his factory. The automobile industry uses EOT cranes to handle raw materials.
Smaller workstation cranes, such as jib cranes or gantry cranes, handle lighter
loads in a work area, such as CNC mill or saw.
Almost all paper
mills use bridge cranes for regular maintenance needing removal of heavy press
rolls and other equipment. The bridge cranes are used in the initial
construction of paper machines because they make it easier to install the heavy
cast iron paper drying drums and other massive equipment, some weighing as much
as 70 tons.
In many instances
the cost of a bridge crane can be largely offset with savings from not renting
mobile cranes in the construction of a facility that uses a lot of heavy
process equipment.
Single girder top
running cranes utilized for medium to heavy fabrication. These overhead cranes
are ideally suited to low buildings, where a high hook lift height is required.
The top running
configuration is best used in cases where the end user has issues with
headroom. The most space efficient configuration is the double girder, top
running crane system.
Lifting capacity:
0.25-20ton
Span length:
7.5-32mtrs
Lifting height:
6-30mtrs
Working duty:
Class C or D
Power: AC 3Ph 380V
50Hz or according to client's requirement
Control mode:
Cabin control/remote control/control panel with pendant line
Double Girder
EOT Crane
The double girder
top running overhead crane is a very heavy duty crane, normally used by larger
manufacturers and steel warehouses.Double girder EOT crane are an excellent choice where
high speeds and heavy service are required. Double girder cranes are highly
suitable for applications requiring walkways, lights and other special
equipment.
Lifting capacity:
5-500ton
Span length:
7.5-32mtrs
Lifting height:
6-30mtrs
Working duty:
Class D
Power: AC 3Ph 380V
50Hz or according to client's requirement
Control mode:
Cabin control/remote control/control panel with pendant line
Single Girder
Underhung EOT Crane
Single girder underhung
EOT cranes, usually suspended from roof trusses, are mainly utilized inside
pumping stations and small workshops, for maintenance purposes. The cranes are
compact in design and construction, making them ideal for low buildings where
maximum hook height is required.
When headroom is not an issue a top or under running
configuration can be used with either the double or single girder bridge crane.
Lifting capacity: 0.5-10 Tons
Span length: 3 m to 25 mtrs
Lifting height: 0.5 m to 80 mtrs
Working duty: Class C
Power: AC 3Ph 380V 50Hz or according to client's
requirement
Control mode: Cabin control/remote control/control
panel with pendant line
