Double-girder Gantry Crane

A double girder gantry crane is a type of bridge crane that has legs at both ends to support the bridge frame on the ground track. It consists of the gantry frame, hoist trolley, crane running mechanism, and electric control system. The crane has a double main beam/girder structure, with a winch hoist that runs on the girders for lifting operations. It travels on rail tracks to handle materials in different positions. Additionally, there may be outstretched cantilevers at the two ends of the main beam for a larger working range.

Key Specifications of Double Girder Gantry Cranes

Load Capacity: The load capacity of a double girder gantry crane is a critical specification that defines how much weight the crane can safely lift. Capacities typically range from 5 tons to over 500 tons. When selecting a crane, it’s important to consider the maximum load it will handle and ensure that the chosen double girder gantry crane model can accommodate the required weight.

Span: The span refers to the distance between the two vertical legs of the crane. Common spans for double girder gantry cranes range from 5 meters to 35 meters, but they can be customized to meet specific operational needs. A wider span allows for greater coverage and versatility in lifting operations.

Lifting Height: Lifting height is the vertical distance the crane can lift loads, which is determined by the height of the supporting structure and the hoist mechanism. Typical lifting heights for double girder gantry cranes range from 6 meters to 18 meters. Higher lifting capabilities are beneficial for tasks requiring significant vertical movement.

Duty Cycle: The duty cycle of an industrial gantry crane indicates its operational frequency and the intensity of use. Double girder gantry cranes are classified into different duty cycles (e.g., A3 to A8), with A3 representing light-duty applications and A8 indicating heavy-duty use. Choosing the right duty cycle ensures the crane can withstand the demands of the application.

Travel Speed: Travel speed refers to the speed at which the crane can move horizontally along the tracks. Standard travel speeds range from 16 to 50 meters per minute, depending on the specific model and configuration. Adjustable speeds can enhance operational efficiency, allowing operators to tailor the crane’s performance to different tasks.

Customizing Specifications

One of the primary customization options is adjusting the specifications of the crane, such as load capacity, span, and lifting height.

Depending on your lifting needs, you can select a crane that can handle loads ranging from 5 tons to over 500 tons.

The span between the legs of the gantry crane can be customized to fit your workspace, allowing for optimal maneuverability and load handling.

Customizing the lifting height involves selecting the right hoist and girder configuration, which can accommodate the height requirements of your facility.

Applications Across Different Industries

Double girder gantry cranes have versatile uses across industries:

Shipping & Logistics

Efficiently load and unload cargo from ships and trucks.

Construction

Move construction materials like steel beams, concrete blocks, and heavy machinery.

Manufacturing

Transport large parts and equipment within production facilities. Warehousing: Lift and move heavy pallets or storage containers with precision.

FAQ

Q: What is the difference between a single girder and double girder gantry crane?

A: Single girder cranes are suitable for lighter loads and smaller spans, while double girder cranes handle heavier loads and longer spans with higher stability.

Q: Can your gantry cranes be customized?

A: Yes, we can customize lifting capacity, span, height, power supply, control method, and structure based on your application requirements.

Q: Do your gantry cranes support variable frequency drives (VFD)?

A: Yes, VFD can be applied to hoisting, trolley travel, and crane travel to ensure smooth and precise movement.

Q: What parameters should I provide to get a quotation for a gantry crane?

A: Please provide the required lifting capacity (tonnage), span, lifting height, and application environment. If available, also share your power supply and preferred control method. The more detailed your information, the more accurate our proposal will be.

Q: What is the power supply standard for your gantry cranes?

A: Our standard is 3-phase 380V/50Hz, but we also support 220V~690V, 50Hz or 60Hz according to your region.

Q: What safety features are included with the gantry crane?

A: Our cranes come with overload protection, limit switches, buffer devices, anti-collision systems, and optional windproof clamps for outdoor use.

Q: What control methods are available?

A: We offer pendant control, wireless remote control, and cabin control. PLC smart control is also available on request.
