Outdoor material yards and construction sites cannot do without efficient and reliable lifting equipment. When indoor single girder bridge cranes are used outdoors, they often suffer from insufficient bearing capacity and stability, making it difficult to meet the requirements of heavy loads and large spans. The double girder gantry crane is specially designed for outdoor use, with a stable structure and strong performance. It is suitable for harsh environments, with strong load-bearing capacity, durability and reliability. It can easily lift steel, building materials, components and loose materials, and is suitable for various outdoor industrial material yards.
This double girder gantry crane can withstand harsh outdoor environments, with strong bearing capacity and durable skin. Whether it is steel, building materials, large components, or various bulk materials, they can be easily lifted.
Difficulties in outdoor material yard operations
The outdoor material yard has a complex environment and stricter requirements for lifting equipment. Common challenges include the following:
Heavy load and large span: The material yard is heavy in stacking goods, spacious in space, and ordinary equipment has insufficient load-bearing capacity and span, making it impossible to cover the entire operation area.
The outdoor environment is harsh: with frequent exposure to sunlight, rain, and strong winds, equipment is prone to rusting, and insufficient stability can also pose safety hazards.
High homework frequency: The lifting operations in the material yard are co.ntinuous and frequent, and the equipment cannot withstand frequent failures. Shutdown for maintenance will delay the construction period and increase costs.
The double girder gantry crane has targeted the above problems and become the preferred equipment for outdoor material yard lifting.
Comparison between Double Girder Portal Crane and Single Girder Bridge Crane
| Comparison items | Double girder gantry crane | Single girder bridge crane |
| Venue usage | Outdoor open spaces, material yards, construction sites, and ports can be directly used by laying tracks without relying on factory beams and columns | Indoor workshops and factory interiors must rely on the installation of factory beams and columns, and are not suitable for long-term outdoor operations |
| Lifting capacity | Heavy duty type, with a large rated lifting capacity, capable of lifting heavy objects of tens or even hundreds of tons | Lightweight type, suitable for lifting light and small goods, prone to deformation under heavy loads |
| Structural stability | Double main girder structure, strong rigidity, wind resistance, deformation resistance, can maintain stability even in outdoor windy weather | Single main girder structure, weak rigidity, obvious shaking, not suitable for strong winds and complex outdoor environments |
| Span range | Large span, capable of covering a large area of material yard, meeting the lifting needs of the entire area | Small span, limited by factory space, limited applicability |
| Durability | The body is treated with anti-corrosion and rust prevention, suitable for outdoor exposure to sunlight and rain, with a long service life and low maintenance costs | Tend to indoor use, prone to corrosion and damage during long-term outdoor operations, with high maintenance frequency |
| Work efficiency | Stable lifting speed and accurate positioning, capable of continuous high-frequency operation, suitable for large-scale material transportation | Suitable for light and scattered goods, with low efficiency in heavy and high-frequency operations |
Simply put: Indoor lightweight, small-scale operation, suitable for single girder bridge cranes; Outdoor material yard, heavy-duty, large-span, long-term outdoor operation, suitable for choosing double girder gantry crane.
The advantages of double girder gantry crane
1. Heavy duty stable lifting, suitable for various heavy materials
Adopting a double main beam reinforced structure, the load-bearing capacity far exceeds that of ordinary lifting equipment. Whether it is bundled steel, large components, or heavy containers, they can be lifted and transported smoothly, ensuring the safety of goods and operations.
2. Wind resistant and durable, suitable for harsh outdoor environments
The whole machine is treated with rust prevention, anti-corrosion, and rainproof measures, and equipped with windproof anchoring devices, which can withstand strong outdoor winds and are not easily damaged even after long-term outdoor use. The maintenance frequency is low.
3. Large span coverage, no dead corners in homework
According to the actual size of the material yard, a suitable span can be customized, and one device can cover the lifting, stacking, loading and unloading work of the entire yard without the need for multiple devices to cooperate, reducing site occupation and improving operational efficiency.
4. High safety factor, more reassuring homework
Equipped with multiple safety protection devices, including lifting limit, overload protection, windproof braking, etc., it meets industrial safety standards and ensures long-term operation.
5. Flexible customization, tailored to actual needs.
According to the tonnage of the material yard, the size of the site, and the frequency of operations, the lifting weight, span, and height can be customized. It can also be equipped with grab buckets, electromagnetic suction cups, and other accessories to adapt to the lifting of different goods such as bulk materials, steel, and building materials.
Common application scenarios
1.Steel material yard
For heavy metal materials such as steel plates, steel coils, and steel sections, specialized lifting equipment is used to achieve fast loading, unloading, stacking, and transportation, eliminating manual handling and improving the efficiency of steel circulation.
2.Building materials sand and gravel yard
Paired with a grab bucket, it can easily load and unload bulk and heavy building materials such as sand and gravel, cement components, etc., solving the problems of low manual loading and unloading efficiency and high labor intensity.
3.Port Logistics Transfer
Used for stacking and transporting containers and large cargo, suitable for outdoor open spaces, connecting the lifting links of water and land transportation, and improving logistics turnover speed.
4.Infrastructure construction site
Lifting construction steel, large components, and mechanical equipment to meet the heavy lifting needs of outdoor infrastructure and accelerate construction progress.
Precautions for use
1. Regularly check the windproof device of the equipment and provide fixed protection in strong wind weather.
2. Timely carry out rust removal, lubrication and maintenance of the machine body to extend the service life of the equipment.
3. Overloading operations are strictly prohibited, and goods must be lifted strictly according to the rated tonnage.
4. Regularly inspect the circuit and braking system to eliminate safety hazards.
Summary
For outdoor material yards, choosing the right lifting equipment is the key to improving efficiency and reducing costs. Single girder bridge cranes are more suitable for indoor light operations, while double beam gantry cranes, with their advantages of heavy load, stability, durability, and adaptability to outdoor environments, have become an ideal lifting solution for industrial material yards and open-air storage yards.
