Gantry crane

Product Overview

The Weiyuan L-Shape Single Girder Gantry Crane is an innovative and highly efficient lifting solution, uniquely designed for handling materials in spaces where clearance is a challenge. Its distinctive L-shaped leg structure, combined with a robust single girder frame, creates a large, unobstructed working area underneath the cantilever. This makes it exceptionally easy to maneuver long and bulky items. Paired with a powerful electric hoist, this rail-traveling gantry crane is the perfect choice for outdoor yards, building material shops, and precast concrete facilities that require both strength and superior operational flexibility.

Product Advantages

Optimized Workspace for Handling Long Materials

The primary advantage of this crane is its smart L-shaped design. Unlike traditional A-frame gantry cranes, the single L-shaped leg provides a massive open space on one side. This allows for unrestricted movement and makes it incredibly easy to lift and transport long items like pipes, steel beams, or timber without obstruction. It effectively expands your usable workspace and simplifies complex lifting tasks.

Robust and Reliable Outdoor Construction

Built for steady performance in demanding outdoor environments, this crane features a strong, box-type single girder made from high-grade Q235B and Q345B steel. The structure is engineered for an A3-A5 work duty, ensuring it can handle regular lifting cycles with exceptional durability. The durable epoxy zinc-rich paint finish and optional rainproof devices for the hoist and electricals guarantee a long service life with excellent resistance to weather and corrosion.

Enhanced Operator Safety and Control

We prioritize operator command and safety. This crane can be equipped with multiple control methods to suit your needs, including a fully enclosed, ergonomic cabin that provides the operator with excellent visibility and protection from the elements. For added flexibility, a wireless remote control is available. The crane includes a comprehensive suite of safety features, such as a weight overload protection device, an emergency stop system, and current overload protection, ensuring every lift is performed securely.

Fully Customizable to Fit Your Needs

We understand that every operation is unique. We offer extensive customization for this L-shape gantry crane. You can specify the lifting capacity (from 5 to 32 tons), span, lifting height, and power supply. Whether you need a standard 15-ton configuration or a tailored solution for a specific application, we engineer the crane to be a perfect fit for your facility and workflow.

Application Scenarios

• Building Material Yards: The ideal crane for loading and unloading trucks with long items like steel rebar, pipes, and lumber, streamlining yard operations.
• Precast Concrete Yards: Provides the space and stability needed to handle long concrete beams, panels, and poles with ease and precision.
• Manufacturing Plants: Excellently suited for moving raw materials, large components, and finished products, especially long items that are difficult to handle with other cranes.
• General Warehousing & Storage Yards: A versatile solution for organizing and moving oversized stock, maximizing storage space and improving material flow.

Frequently Asked Questions

Q: What is the main benefit of the L-shaped leg design?

A: The L-shaped leg creates significant open space under the crane on one side. This is extremely useful for lifting and moving long objects, such as pipes or beams, as they can be maneuvered without being blocked by a second set of support legs. It gives you much more flexibility compared to a standard A-frame gantry crane.

Q: Is this 15-ton crane suitable for outdoor use?

A: Yes, it is specifically designed for robust outdoor performance. For dedicated outdoor use, we incorporate extra protective features. This includes rain covers for the hoist and electrical systems, a more durable paint finish, and optional wind-speed alarms to ensure safe operation in various weather conditions.

Q: What is the difference between cabin control and remote control?

A: Cabin control places the operator in an enclosed cab attached to the crane, which is ideal for high-frequency use as it protects the operator from the environment. A wireless remote control gives the operator the freedom to move around the worksite, manage the lift from the safest vantage point, and work more closely with ground crews. We can equip the crane with either or both methods.

Q: What information do you need to provide for a quote?

A: To provide an accurate quote, please tell us your required lifting capacity (e.g., 15 tons), span, lifting height, and the power supply in your facility (voltage/frequency). It is also very helpful to know the type and size of materials you will be lifting and your preferred control method. Our team will then create a detailed technical proposal for you.
