OEM Single Girder Gantry Crane for Railway yard
OEM Single Grider Electric Goliath Gantry Cranes for yard construction offer an economical solution
to overhead cranes when the building is inadequate to support a bridge
crane or the crane system is to be located outdoors. A box girder
portal gantry crane is a gantry crane that utilizes a "box"
configuration in fabricating the girder. This box girder design
incorporates a four-sided box with a running surface plate for the
hoist trolley attached to the bottom of the box. The advantage of
the box girder is that it possesses greater loading capabilities
and is able to span greater bridge distances. The crane is
generally utilized in pairs with the hoisting mechanism operating
on rails attached to the top of each box girder.
Gantry portal crane can be applied to both single girder and double
girder format. It is ideal for outdoor applications where lifting
devices can be applied without the cost of supporting steelwork.
Indoor applications are also available where with a low ceiling and
overhead cranes are not suitable. Typical occasions of goliath
gantry crane include steel stock yards, loading areas, the concrete
industry, ship building, and workshops.
Gantry/Portal/Goliath cranes are widely used in the following
5.Marble / Granite Industry
7.Bridge Construction sites
8.Road Construction Sites
Design features include:
1. Main girder:
is welded of steel plates, connected by high-strength precision
bolt. There are sliding rail for trolley to travel upper the girder
which is fixed on outrigger by high-tension precision bolt
a. Consist of rigid outrigger and flexible outrigger, all
connection points are connected by high-tension bolt
b. The ladder is used by operator to enter into cab or arriving at
c. when the span>30m, there need a flexible leg aiming at
reducing the lateral thrust the trolley has to the rail when the
girder load objects.
3. Travelling mechanism
consist of driving gear box and passive wheel box.
a. The driving gear box supplies power to realize the crane’s
b. what the difference between driving gear box and passive wheel
box is that passive wheel box lacks transmission structure such as
dynamo, reducer and a pair of exposed gear
4. Trolley with hoist
is made up of trolley frame, winch and pulley block
a. Trolley frame welded of steel plate is the loading and
travelling mechanism of trolley with hoisting
b. Winch is the lifting mechanism of trolley..when it works, wire
rope affects the pulley as rising and falling movement, which makes
suspended objects lifting and lowering
Warning: wire ropes need to be examined regularly and changed in
time if there is a 10% broken wires, loosen wires and wearing down.
a. Glass window through which one can watch overall working
condition is installed in the front and two sides of the cab
b. Electric cabinet as a group of independent cabinet , fixed
outside of cab is connected by control cable and linkage station
which is set up in the cab
6. Electrical system
a. lifting motor, crane travelling motor and hydraulic power motor
are included. The whole electrical system is controlled by PLC.
b. two ways to operate the crane: cab operating and remote
c. Electric components are imported from Schneider in Germany
platform is installed in order to maintain the crane, the
protective guard is added to protect the safety of servicemen.
