MG Type Heavy Duty Double Girder Gantry Crane is extensively used for lifting and loading, unloading works in outside warehouse or railway stations.
Equipped with other lifting appliances, it also can be used for special purpose. It gains many popularities and sold well at home and abroad.
Lifting capacity: 10~50/10t
Span: 18~35m (it can de redesigned as client’s requirements)
Lifting Height: No limited (can be designed according to client’s requirement)
Working Duty: A5-A7 (according to the use frequency and working time)
Power supply: 3ph, 380V, 50HZ (or under customer’s requirement).

Configuration：
1. MG model double girder gantry crane consists of four main parts: the bridge structure, the trolley traveling mechanism, crane traveling mechanism and the electric equipment.
2. The girders and frame are welded structure without weld joint and high degree of vertical and horizontal rigidity.
3. The lifting mechanism is electric trolley, it can equip with hook and other tools to lift containers. Some rail, gear, wheel relevant parts with good quality manufactured by our own group, the quality is easily been controlled.
4 .The main electric parts are Siemens and other famous brand. The motor is heavy duty slide ring type, Xindali brand or some other brand top quality in China. The buffer adopts polyurethane material and the brake is electric hydraulic type.
This crane has two kind conductive forms: cable and slip line. Slip line are first recommended, the conductive form and position should be definite when place an order.

Operation mode:
Operation is in the cabin room which is commodious and comfortable.
Safety protection devices:
Close type hook, anti-collision system, weight overload protection device, emergency switch and so on.
Good painting:
Primer and finishing paint, color as the clients’ requirements.

Advantage：
High working duty
Widely usage
High quality
Easy use
Easy maintenance
Long life time

Features:

1. Applicable occasions
Using in outdoor, road construction area, 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.
2. Machine
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.
3. Power supply
This type crane adopts the cable and drum or the slide wire as its conductive devices.
4. Operation model
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 and maintain.
5. Electric equipment
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.
6. Safety protection devices
Weight overloads protector, extreme lifting position limiter, extreme travelling position limiter, the cleaning board, the buffer and the cover protection.
7. 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 customers demands.
8. Before delivery
We also supply the general pre-installation, performance test, etc.
9. 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 18001.
