Double Girder Gantry Crane

Double girder gantry crane is mainly composed of main beams, end beams, crane travelling system, the trolley travelling, electrical system, supporting legs and other components. It can use cable reel power supply, with diesel generator power supply or bare copper slip line power supply. In addition, this crane is widely used at outdoor freight yard and bulk cargo handling. The crane structure can adopts European-style configuration, known as the European double-beam gantry crane.

Double girder gantry crane carrying capacity is strong and the span can be very large. The overall stability is good. Compared with single girder gantry crane, the overall rigidity of the double form is stronger. Because the gantry crane has two girders, the entire structure has stronger stability. In different condition, our technicians design various products that meet the customers’ requirements.

Main Types of Double Girder Gantry Crane

U Frame Double Girder Gantry Crane

U type double girder gantry crane is applied to general materials handling service in outdoor freight yard or along railway lines, such as loading, unloading, lifting and transferring work.

As there is more space under legs of gantry crane, it’s fit for conveying larger products. Its lifting weight is 5-50 tons; proper span is 18-35 meters; working temperature is -20 degrees to +40 degrees.

Saddle support isn’t needed for U type gantry crane, so overall height of crane is reduced given certain lifting height.

Due to a larger space of the U model gantry crane between legs, which is also different from other gantry cranes that become the biggest features, it is suitable for larger objects to convey.

This crane is widely used at the open ground and warehouses loading and unloading materials, and outdoor equipment production sites and cargo handling. Mode of operation has ground wireless remote controlling and cab operation. You can make the two kinds of models work together.

A Type Double Girder Project Gantry Crane

The machine adopts two girders and equips with hooks to assist. Its characteristics are mainly used for general loading and unloading and crane handling in construction factories such as roads, bridges and power plants.

In addition, the whole machine adopts structure of truss type. Then, its own weight will turn lighter, the wheel pressure will be less, and the overall performance will be reliable. When the span ≥ 35m, the legs are divided into rigid legs and flexible legs, flexible legs is to compensate for structural deformation caused by temperature.

Advantages of the Double Girder Cranes

Compared with single-beam gantry cranes, double-girder gantry cranes have better stability and the scope of application is also wider. Although the price is relatively high, the space between the legs can be reasonably used to lift the goods. And the loading goods can be left and right.

In addition, the operator can work between the two main beams with high safety performance. However, the structure of a single beam can not meet this demand for transporting operations. Besides, the variety of products have different settings in terms of span and lifting weight. If the customer’s product is larger, our advice is to choose a double-beam structure.

No matter what it is the warehouse handling or engineering operations, our products can finish the task well with many advantages. For example, when workers operate in a factory with exceptionally high temperatures, our products have special materials that are not subject to high temperatures, and are more suitable for this type of mechanized operation.

What Are the Gantry Crane Uses in the Industry?

❖ Shipbuilding
Gantry cranes are usually deployed in the shipbuilding industry. Shipbuilding requires a lot of heavy work, which can be done with a gantry crane. The crane helps to traverse the ship, and some huge engine parts are installed in it, such as the ship engine. The crane helps the ship move during the construction phase.
❖ Automobile industry
There are some gantry cranes that can be used to lift the car engine from the vehicle. Although the weight of a car engine varies from vehicle to vehicle, it is important to have a crane to support the entire lifting process.
❖ Warehouse
In a warehouse, it is always necessary to lift heavy objects. Gantry cranes can help complete this lifting process. These types of cranes exist in almost all types of warehouses.
❖ Production unit
Some gantry cranes can be used in production units. Help move parts from one work cell to another.

❖ Construction site
Gantry cranes are very useful in construction sites. They can be used to lift heavy objects present in these areas.

What Are the Crane Working Conditions?

✥ The power supply of the crane is three-phase AC (three-phase four-wire system), the frequency is 50Hz / 60Hz, and the voltage is ≤1000V (can also be 3kV, 6kV or 10kV according to your needs). The voltage fluctuation of the power supply system at the access point of the crane feeder should not exceed ± 10% of the rated voltage.

✥ The track installation for the crane shall meet GB / T tolerance requirements.

The grounding resistance of the crane running track should not be greater than 4Ω.

The altitude of the place where the crane is installed and used does not exceed 1000m (if it exceeds 1000m, the capacity of the motor should be checked according to the provisions of GB 755, and when it exceeds 2000m, the capacity of the electrical components should be checked.)

✥ The radiant heat temperature of the hoisted items to the hook of the crane should not exceed 300 ° C.

✥ Climatic conditions when the crane is working indoors:

The ambient temperature does not exceed + 40 ° C, and the average temperature within 24h does not exceed + 35 ° C.

Ambient temperature is not lower than -5 ° C; relative humidity does not exceed 50% at + 40 ° C.

✥ Climatic conditions when the crane is working outdoors:

The ambient temperature does not exceed + 40 ° C, and the average temperature within 24h does not exceed + 35 ° C.

The ambient temperature is not lower than -20 ° C, and the relative humidity is allowed to temporarily reach 100% when the ambient temperature does not exceed + 25 ° C.

The working wind pressure should not be greater than: 150Pa inland (equivalent to class 5 wind) and 250Pa in coastal area (equivalent to class 6 wind); the maximum wind pressure in non-working state: generally 800Pa (equivalent to class 10 wind).

How to Maintaine Gantry Crane?

It is critical to inspect and maintain gantry crane equipment regularly in order to ensure high work efficiency and safety to extend its service life.

The following are some crane maintenance tips:

Lubricating
Various crane mechanisms should be lubricated regularly, because the performance and life of these mechanisms depend to a large extent on lubrication.
Wire rope
Check the wire rope to make sure it is in good working condition. When wire breakage occurs or the abrasion reaches the scrap standard, the wire rope should be replaced in time.
Hooks and lifting accessories
The hooks and lifting accessories should be checked regularly to ensure they are in good working condition.
Pulley block
Check the wear of the rope groove, whether the rim is cracked, and whether the pulley is stuck on the shaft.
Wheel
Regularly check the rim and tread. When part of the rim is worn or chipped to 10% thickness, the wheel should be replaced with a new one. When the diameter difference between the two driving wheels on the tread exceeds D/600, or the tread has serious scars, the ignition should be re-ignited.
Brake
Check the brakes every shift. The brakes must be accurate and do not jam the pins. The brake shoe should match the brake wheel correctly, and the clearance should be equal when the brake is released.
