What is a Double Girder Gantry Crane?

The double girder gantry crane is an essential lifting equipment. Its primary feature is the double beam design, which allows for a greater lifting capacity compared to single beam gantry cranes. This type of crane is especially suited for lifting heavy materials, with capacities ranging from 10 ton to even 1000 tons. Double girder gantry cranes are commonly used in various fields, including ports, manufacturing, and construction. Our double girder gantry crane is tailored to your specific needs, making your lifting operations efficient and safe.

Features

Portal Structure
The portal frame is composed of the main girder and leg, and the legs are connected under the main girders, so that it can walk smoothly. Sometimes, in order to expand the scope of work, cantilever crane will be installed at both ends of the main beam.
Double Girder Structure
It consists of two parallel-arranged box type or truss type main girders, which span transversely across rigid legs on both sides, forming a gantry frame.
Multi-dimensional Motion Mechanism
It operates by the collaboration of three parts of traveling mechanism, trolley mechanism and lifting mechanism.
Traveling Mechanism: It drives the crane to move longitudinally along the ground tracks, adopting a four-corner, eight-wheel (or more) equal load distribution design, with independent drive by motors and reducers.
Trolley Mechanism: It moves transversely on the main girder tracks and is equipped with a double-drum lifting mechanism (main and auxiliary hooks lift independently).
Lifting Mechanism: It features a wire rope winding system, hook assembly, or specialized lifting equipment (such as container lifting gear).
Modular Mechanical Components
The main girders are manufactured in segments, and the legs are split into upper and lower sections for easy transportation and on-site assembly.
Wide Application Field
Because of its strong versatility and high site utilization rate, gantry crane can be applied to many fields such as ports, ships, industrial manufacturing, construction, warehousing and logistics, both indoors and outdoors.
High Safety Coefficient
The gantry crane designed has a high safety factor and is equipped with a variety of safety equipment, such as limit protection system, overload protection device, brake safety system, electrical protection system, wind anti-skid system, monitoring and alarm system, lighting system, emergency switch and so on.
Strong Environmental Adaptability
Gantry cranes can adapt to various site and climate conditions, as well as different working environments, such as wind and moisture, high temperature and severe cold, rain, snow and dust, etc.

Cooperation Brands

Core components are selected from many internationally renowned brand merchants.

Comprehensive Buyer’s Guide for Double Girder Gantry Crane

Identify your specific usage requirements
It usually includes lifting capacity, lifting height and span.
Assess your work environment to determine whether it is indoor or outdoor
For indoor gantry crane applications, emphasize space adaptability and noise control. Conversely, for outdoor use, factors such as wind resistance, rain protection, sun shielding, and corrosion resistance should be taken into account.
Clarify the types of gantry crane
Truss type is composed of welded angle steel and is hollow - shaped. This kind of structure is lightweight and has good wind – resistance; Box type is a box-type beam structure with iron sheet sealing on the exterior, featuring high structural strength and good stability.
Determine the operation mode of the gantry crane
Depending on your workspace, you may need either a fixed or a mobile gantry crane.
Fixed Gantry Crane: This option is suitable when your operations are limited to a specific area. In this case, you only need to install the crane at the designated worksite.
Wheeled System: This system is ideal for cranes that need to move freely within the workspace, providing greater flexibility.
Track System: If your operations require movement along a track, you should consider installing a track-mounted crane.
Work Level Adaptation
The required work level of a gantry crane should be determined based on its frequency of use and the intensity of the tasks. In environments such as port terminals and large logistics transfer centers, where cranes are frequently used and handle heavy loads, it is essential to choose equipment with a high working capacity. On the other hand, for smaller factories with lower usage rates, gantry crane with a relatively lower working capacity may be sufficient.
Effective cost accounting and budget control
In line with the project's actual budget, you should comprehensively evaluate product quality, performance, after-sales service, and other factors to assess cost-effectiveness. Choosing the right gantry crane for yourself.
Attach importance to after-sales service
After purchasing a gantry crane, after-sales support service is of great significance. Qualified suppliers, possessing a service system that's professional, digital, and customized, should help customers make their equipment operate safely and in compliance with regulations and work efficiently and low maintenance costs. Accordingly, after-sales service should cover full-process support from delivery to lifelong maintenance. This includes installation and commissioning services, preventive maintenance plans, repair and emergency response, as well as operation training.
