Cantilever gantry crane
What is a cantilever gantry crane ?cantilever gantry crane is one of the most common types of gantry cranes,, with the main beam of which is outreached at one side or both sides to form cantilever, which helps increase the crane span and workspace. The cantilever gantry cranes are widely used in many outdoor workplaces, such as railroad, freight yard, port and shipyard.
Cantilever Gantry Crane Design
Based on different terms and standards, the cantilever gantry crane has many different types for you to choose from, and they are classified as single girder and double girder cranes based on girder construction, rail mounted and rubber tyred gantry cranes based on how they move, box type and truss gantry cranes based on metal structure designs.
This type of gantry crane is a popular lifting tool applied in a variety of industries to improve efficiency and productivity. We design several different styles of gantry cranes to meet almost all requirements of customers.
The cantilever gantry crane is a popular lifting tool used to improve efficiency and productivity in a variety of industries. Yuantai Crane provides a variety of 10 ton cantilever gantry crane designs to meet nearly all customer requirements and application conditions.
Cantilever design- Single Cantilever vs. Double Cantilever
The cantilever of the 10 ton gantry crane refers to the part of the main beam that reach out beyond the span. In another words, it is the part of the main beam of the gantry crane beyond the width of the travelling track or rail, embedded on the ground, which is the cantilever of the gantry crane.
- Double cantilever gantry crane: the most common structural form, the force of the structure and the effective use of the site area are reasonable.
- Single cantilever gantry crane: This structural form is often selected due to site constraints.
The main function of the gantry crane cantilever is to extend the main beam beyond the running track of the gantry crane to facilitate loading and unloading of objects and materials. Normally, the covering area of gantry crane span is the production site, and the finished products or materials can be hoisted, loaded, transferred or unloaded by the gantry crane cantilever reaching out of the span without affecting the normal production within the span.
Gantry girder design- Single girder vs. Double girder
Based on your practical lifting requirements, the cantilever gantry crane 10 tons can be designed with single and double girder construction. Because a double girder cantilever crane has a greater lifting capacity than a single beam design, it is also much more expensive.
Girder structure design : Box girder vs. Truss Girder
Box or truss structures can be adopted to build the cantilever gantry crane. The
box type cantilever gantry dominates because it is simple to fabricate. When working outside, such as at a shipyard, port, or quay, a
truss gantry crane is the best option to fend off storms and severe winds.
Gantry form design - Full Gantry vs. Semi Gantry
Furthermore, for various work areas, we provide full gantry and semi gantry cantilever crane for your consideration.
Semi-gantry cranes are a type of single leg gantry that is commonly used in areas where space is limited.
Gantry travelling design - rail travelling vs. Rubber tyred gantry
The cantilever gantry cranes can be designed with rail travelling gantry & rubber tyred gantry. The rail gantry is featured with large capacity loads handling within a designated working area, confined by gantry rail embedded on the ground and cantilever designs. Rubber tyred gantry designs provide high movability, which are widely used for outdoor material handing .
Crane attachment for cantilever gantry cranes
To handle different materials, each type of cantilever gantry crane can be equipped with a variety of lifting devices such as a hook, grab, and spreader. It also has saddles on top of the main beam to transmit a reasonable amount of stress to the crane structure. Furthermore, the design of a 10 ton gantry crane should take into account the need for structural deformation caused by temperature differences.

Why Use Cantilever Gantry Crane? Benifits of gantry cranes
Many outdoor use 10 ton gantry cranes are designed with cantilevers, which the portion of the main girder that extends beyond the crane runway on one or both sides. The cantilever design has several advantages, which are listed below.
- When compared to a gantry crane without a cantilever, this the cantilever cranes can increase the span, making it easier to load, unload, and move cargo on one or both sides of the cantilevers without interfering with normal production within the span. As a result, the cantilever gantry crane is a very practical design for a wide range of applications.
- The cantilever gantry crane we design requires little maintenance and minimizes equipment downtime to improve outdoor crane efficiency.
- The cantilever crane has a low dead weight, and the optimized design puts less strain on the gantry crane structure.
- A reasonable and compact structure design allows for the most efficient use of available space.
- Cantilever gantry cranes are typically outfitted with a variety of safety devices to ensure that they operate safely and smoothly for indoor use or outdoor use.
Gantry Crane Safety Devices
The safety devices are critical components in preventing accidents. You can choose from a variety of protection devices, such as an overload limiter, a lifting height limiter, an interlock protection device, a buffer, a windproof and anti-slip device, an anti-swaying device, a rain cover, and an anti-collision device.
Depending on your practical applications, some safety devices are optional.
Outdoor gantry crane safety devices
Many types of gantry cranes are designed for outdoor use, which are recommended to be equipped with a wind resistance device and a rain cover to protect the equipment. When two or more cranes or hoist trolleys share the same track, an anti-collision device should be installed.
The safety devices should be inspected and maintained on a regular basis in the workplace to ensure they are in good working order. If a component fails, it should be repaired or replaced as soon as possible.
Safe Operation of cantilever gantry crane
Cantilever gantry crane is typically operated via wireless remote control and cabin operation, which can greatly improve operator safety. However, most gantry crane accidents are still caused by human error, so crane operators should raise safety awareness and adhere to safe operation regulations.
Operators should be rigorously trained on crane knowledge and have the necessary competence before operating a crane. Cabin drivers, in particular, should obtain relevant qualifications. Furthermore, they should be fully prepared for the cantilever gantry cranes, including crane weight, load type, lifting speed, and other basic information.
Operators should wear protective clothing and devices such as a long-sleeved shirt, safety glasses, and a helmet while operating. They must strictly adhere to all operational rules and regulations. Any carelessness or laxity should be avoided. Furthermore, do not make any rash decisions or assumptions during the operation.
Gantry Crane Safety Requirements
- Crane operators should inspect the equipment and some critical components, such as the hoist, limit switches, and wire rope, daily before use to ensure they are in proper working order. Any deformation or damage should be repaired as soon as possible.
- Check the working environment before beginning operations to ensure that there are no potential hazards that could jeopardize the safe operation of the equipment.
- The crane travel path should be kept clear at all times, and loads should never be suspended above workers.
- Never use wire rope to pull loads or other objects as a sling.
- Ensure that the loads are properly rigged and that they are not overloaded.
- The lifting motion should be smooth and stable. Any kind of quick movement should be avoided.
- Preventive maintenance should also be performed to ensure the equipment's safety.
To protect the crane from harsh environmental conditions such as thunderstorms and strong winds, operations should be halted.
A safe gantry crane operation not only ensures personnel safety, but also maintains normal production and promotes efficiency. As a result, whether a crane manufacturer or a crane operator, gantry crane safety should be prioritized. Contact us to get your customized 10 ton gantry crane for your application.
