Gantry Cranes
Industries ranging from ports and shipyards to manufacturing plants and warehouses actively rely on the 100-ton gantry crane—a fundamental piece of heavy-duty equipment designed to handle and lift massive loads. Specifically, it is utilized for managing heavy cargo and ship components in maritime settings, while proving essential for efficiently moving large items in industrial and logistics facilities.
1. Girder
Gantry crane main girder structures typically include truss girders and box girders. Angle steel or I-beams serve as the primary materials that manufacturers weld together to form gantry crane truss girders.
2. Lifting Mechanism
A crane works by using a pulley system to redirect the force required to lift a load and distribute the force over a greater distance. A boom pulley is installed at the end of the boom.
3. Cab
A fixed-cab crane primarily serves as a vehicle to lift and move heavy loads in confined spaces like loading docks and warehouses. This design enables the operator's cab to extend directly over the top of a trailer or truck bed, allowing the operator to control all lifting operations from inside.
4.Hoist
This component controls vertical lifting. The hoist is attached to the pulley assembly, which allows the hoist to traverse back and forth along the bridge as needed.Its load capacity depends on its design and construction.
5. Braking System
The widespread adoption of brakes in gantry crane systems stems directly from their superior stopping power and reliability.These brakes consist of a rotating disc mounted on the crane shaft and a fixed caliper.
Double-girder gantry cranes are essential lifting equipment in factories, ports, cargo yards, and other locations. Their advanced design is designed to handle the loading, unloading, and handling of large cargo. The main structure of a double-girder gantry crane consists of two parallel main beams and two outriggers at each end, which support the entire gantry and move along ground tracks.

Heavy-duty gantry cranes are primarily used for lifting Tunnel Boring Machines (TBMs) and are large-scale lifting equipment specifically designed for debris removal, equipment transportation, and shield support operations in subway tunnel construction. They can automatically perform debris removal, unloading, and cycle operations to meet the material transportation requirements of tunnel construction. In addition to debris removal and unloading functions, this crane can also perform critical tasks such as tunnel pipe plate lifting and shield machine assembly, making it an indispensable piece of equipment in shield construction.

A 100-ton gantry crane is a heavy-duty lifting device designed for lifting heavy loads in a variety of industrial applications. The following are the key features commonly found on 100-ton gantry cranes:
These characteristics contribute to the performance, safety, and efficiency of a 100-ton gantry crane. When selecting a gantry crane, it is important to carefully evaluate these characteristics to ensure that the crane meets specific application needs and complies with industry standards and regulations.
100-ton gantry cranes offer high lifting capacity and versatility, making them widely used in a variety of industries requiring the lifting and movement of heavy and large loads. Here are some common applications and industries for 100-ton gantry cranes:
The versatility of 100-ton gantry cranes makes them indispensable in industries that handle heavy loads and require efficient and safe lifting solutions. Manufacturers carefully consider the specific needs and constraints of each industry. Therefore, they customize gantry cranes accordingly in order to ensure optimal performance and safety.
Customizing a 100-ton gantry crane requires consideration of operational requirements, environmental conditions, and long-term development plans. Key factors to consider include:
Lifting capacity: Specify the required lifting capacity or whether a primary/auxiliary hook configuration (e.g., 50/10 tons) is required.
Span (S): The distance between the centerlines of the crane rails, which determines the area covered.
Lift height (H): The maximum distance between the center of the hook and the ground. This height must be determined based on site obstructions (e.g., cargo piles, vehicles) and the desired stacking height.
Duty class (A): Select between A5 and A6 based on frequency of use and load rating.
Environmental: Consider the operating environment. Cranes used outdoors may require additional weatherproofing, while cranes used in corrosive environments may require special coatings for protection.
In addition to the parameters mentioned above, customizing a 100-ton gantry crane must comprehensively account for site space, environmental factors, power supply method, control system, structural design, and hook type.
