Industrial Warehouse Double Girder Mobile Gantry Crane with
lifiting trolley Large gantry crane
The double girder mobile gantry crane complies with the national
crane design standard GB/T 14406. The double girder gantry crane is
mainly composed of bridge frame, trolley, crane travel mechanism
and electrical system. MG double beam gantry crane (box type) is
composed of gantry, crane crab, trolley running mechanism, cab and
electrical control system. The gantry crane can be box or truss
structure. The track is on the side of each beam, and the legs are
divided into A-shaped and U-shaped according to user requirements.
The control method can be ground control, remote control, cabin
control or both.
The trolley can move horizontally on a pair of rails on the beam.
According to your working environment, the beam can be box-shaped
or truss-shaped, and can be configured according to customer
requirements! The length of the cantilever can be designed to meet
the needs of the work.
The gantry crane is a gantry crane supported on the ground rail by
two legs. Structurally, it consists of gantry, engine room
operating mechanism, crane trolley and electrical components. Some
gantry cranes have outriggers on one side only, the other side of
the factory or on the trestle supports, called semi-gantry cranes.
The door frame part (including main beam and end beam), outriggers,
lower beam and other parts of the gantry suspension bridge. In
order to expand the operating range of the crane, the main beam can
extend from the supporting legs to one or both sides to form a
cantilever. A crane with a boom can also be used to expand the
operating range of the crane through the pitch and rotation of the
Gantry cranes are all types of cranes which lift objects by an open
winch which is fitted in a trolley and can move horizontally on a
rail. Gantry cranes are an excellent alternative to permanent
indoor overhead cranes, which minimal investment in a new building.
In addition, they can be disassembled and moved to a new location
Double Girder Gantry Cranes are with heavy loads up to 700t and
spans can be over 50 meters. For fabrication and freight-transfer
applications, it can move loads rapidly and smoothly

Gantry Crane Main Features:
Simple structure in linear type ,easy in installation and
maintation . Adopting advanced world famous brand components in
pneumatic parts ,electric parts and operation parts. The crane with
high pressure double crank to control the die opening and closing.
Running in a high automatization and intellectualization,no
pollution. Apply a linker to connect with the air conveyor ,which
can directly inline with filling machine.
Double girder gantry crane lifting capacity: 5ton~900ton
lifting height:3m~25m or customized
Double girder gantry crane main have below Types: MG type double
girder gantry crane,U type double girder gantry crane.
Component of Double Beam Gantry Crane Supplier With Competitive
Using in outdoor, material stocks area, cement plant, granite
industry, construction industry, engineering industry, railway etc.
This type crane is widely applied to the railway goods yard, big
tonnage port, open storage, the container transfer station, and
etc. to handle with the frequent loading and unloading works. This
type adopts the U model door frame, with a big clearance between
the two legs and a very big span..
This crane use one or two trolley as its lifting machine,
comprising the crane and trolley traveling mechanism, lifting
mechanism, cabin, computer room, electric room, and others.
This type crane adopts the cable and drum or the slide wire as its
All mechanism of this crane is operated in cabin. The cabin
travelled along with the crane to avoid the crash with the cargo.
In the cabin, the operator not only can feel its wide and
comfortable space, can also have a good vision to control, surveil
All electric equipment can works normally within the voltage
fluctuation range -15% or +10%. We also design the protection
devices, for instance, the emergency stop system, current overload
protection system, voltage lower protection function, and etc. The
main electrical components (frequency inverter, PLC) adopt the
Siemens, Schneider, Chint or other international famous brand.
Safety protection devices
Weight overloads protector, extreme lifting position limiter,
extreme travelling position limiter, the cleaning board, the buffer
and the cover protection.
Painting and protection
All gantry crane components are handled with shot peening, then
painting. Before delivery, we will do the rust-proof protection on
all open parts. The painting color and shape is according the
we also supply the general pre-installation, performance test, etc.
Norms and standards
In addition to meet the tech demands in the design, manufactures,
installation, test and debugging of this crane, we also made it
strictly in accordance with ISO 9001:2000, ISO 14001:2004 and OHSAS
Mainly Advantages :
The double girder crane are with many advantages:Reasonable
structure and Favorable performance . Smooth starting and stopping.
Safe and reliable traveling
Gantry cranes are mainly used for loading and unloading of outdoor
cargo yard, stock yard and bulk cargo.
Its metal structure is like a door-shaped frame, with two
supporting feet installed under the main beam, which can walk
directly on the track on the ground, and the two ends of the main
beam can have overhanging cantilever beams.
Gantry cranes have the characteristics of high site utilization,
large operating range, wide adaptability and strong versatility,
and are widely used in port freight yards. Applies to the open
warehouse or rail along for general handling and lifting work. Also
can equipped with many lifting device for special work. Prohibited
for lifting high temperature solution, flammable, explosive,
corrosion, overloading, dust and other dangerous operations.
