Double Main Girder Hook Gantry Crane
Product Introduction：
There are box hook gantry cranes and lattice hook gantry cranes for hook gantry cranes, and there are also single and double girder types.
Gantry crane products are suitable for loading, unloading and handling operations in open-air warehouses, yards, railway freight stations, port dock cargo areas, etc.
Hook gantry cranes can also be equipped with a variety of special spreaders (electromagnetic chucks, grabs) for some special operations.
Users should indicate the highest and lowest temperatures of the working environment and the type of power supply and other technical requirements when selecting.
Double-main-girder hook gantry crane is a semi-customized machinery, and the track size and other parameters need to be determined according to your on-site conditions and requirements.
Specification and model:
The specification of double-main-girder gantry crane is namely the lifting capacity, span, and lifting height. The lifting capacity: 20T, 32T, 50T, 60T, 70T, 80T, 90T, 100T, 120T, 200T, 300T, and the maximum is 600 tons. All spans: 7M, 8M, 9M, 10M, 12M, 15M, 16M, 17M, 19M, 20M, 21M, 22M, 33M, and the maximum is 50 meters. The lifting height can be designed according to the actual use needs. The above data are common parameters and can be custom-designed and made according to the user’s technical requirements.
Performance characteristics:
The double-girder gantry crane is a gantry crane that runs on the ground track. The working levels are divided into: A5, A6, A7, A8. The normal use environment should be within the range of -25°C to +40°C, and the average temperature within 24 hours must not exceed +35°C. It is not easy to work in a medium with flammable and explosive substances or in a place with high humidity and corrosive gases. It is also not suitable for lifting molten metals and working in a toxic environment. The operation methods include cab operation and wireless remote control operation. It can be required whether to configure rain-proof equipment. The power supply methods include cable reel and sliding contact line.
Advantages and characteristics of double-main-girder hook gantry crane:
- The hook gantry crane adopts a box-shaped double-girder welded structure to increase the working space and facilitate transportation, installation and maintenance.
- The trolley conducts electricity by using a special-shaped rail cable conducting device.
- The components are standardized, serialized and generalized.
- The power supply forms of the double-main-girder hook gantry crane have cable reel type (divided into left and right ends) and sliding contact line type (divided into left and right ends), which can be selected by users.
- The driver’s cab has a wide field of vision and is equipped with an interlocking console, with flexible, stable and comfortable operation. It can also be equipped with fans, hot air generators, cold air generators, air conditioners, walkie-talkies, etc. according to the user’s requirements.

Usage environment:
Hook gantry cranes are prohibited from lifting flammable, explosive and corrosive items and working in corrosive environments. It can be made into a single-end extended cantilever structure or a non-cantilever structure according to the user’s request, and it can be required whether to configure rain-proof equipment.
Dimension Drawing
Procurement instructions:
The hook gantry crane consists of a bridge, a trolley traveling mechanism, a trolley, and electrical equipment. The bridge adopts a box-shaped welded structure, and the trolley traveling mechanism adopts separate drive. All mechanisms can be operated in the control room or can be modified to operate with a wireless remote control. The conductive form of the crane is divided into two types: cable and contact line, and either one can be selected when ordering. When choosing a hook gantry crane, the order specification table must be filled out, indicating the lowest and highest temperatures of the working environment and the power supply when in use.

FAQ
The maximum lifting capacity of these double girder gantry cranes usually ranges from tens to hundreds of tons.
The lifting capacity can be customized according to the user’s usage requirements to meet the different needs of different industries and applications.
Double girder gantry cranes can be customized to some extent to meet specific needs. Factories usually have the flexibility to modify the following aspects:
- lifting capacity to meet specific weight requirements.
- span and reach to accommodate the dimensions of the work area.
- Special attachments or hooks to handle specific types of loads.
- Control systems to accommodate unique operating preferences or safety regulations.
- Paint colors or finishes to match customer aesthetic or environmental requirements.
- customization of safety features and sensors to specific operating conditions.
The extent of customization may be limited by factors such as engineering feasibility, cost considerations, and compliance with industry standards.
The expected service life of a double girder gantry crane can vary greatly depending on a number of factors. These factors include:
1, maintenance and repair 2, intensity and frequency of use 3, environmental conditions
On average, under normal operating conditions and with good maintenance, the service life of a double girder gantry crane can be 15 to 30 years or even longer.
Yes, there are typically several special requirements for the installation site of a double-girder gantry crane. These may include:
Adequate space and clearance: There should be sufficient room around the crane for its movement and operation without obstruction.
Stable and level ground: To ensure the crane functions properly and remains stable during use.
Sufficient strength of the foundation: To support the weight of the crane and the loads it will handle.
Appropriate access for transportation and assembly: To allow for the delivery and installation of the crane components.
Consideration of wind loads: In areas with high winds, special measures might be needed to secure the crane.
Proximity to power sources: For the crane’s electrical supply.
Clearance from other structures or equipment: To avoid interference during operation.
Compatibility with local building codes and regulations: To ensure legal and safe installation.
The power consumption and energy efficiency of a double-girder gantry crane can vary depending on several factors.
Power consumption is influenced by aspects such as the size and weight of the loads being lifted, the speed at which the crane operates, and the efficiency of the motor and other electrical components. Larger and heavier loads typically require more power to lift and move.
Regarding energy efficiency, modern double-girder gantry cranes are often designed with energy-saving features. These may include efficient motors, variable frequency drives that can adjust power output based on the actual need, and optimized control systems that minimize unnecessary power usage.
