3 Ton Gantry Crane Application

3 Ton Single Girder Gantry Crane Used in Industrial Wastewater Treatment Plant

This 3 ton gantry crane is installed in the wastewater treatment area of an industrial plant, designed to handle sludge and sediment removal operations. The crane is equipped with a stainless steel grab bucket, which allows efficient lifting and transfer of waste materials between sedimentation tanks.

This setup greatly improves the efficiency and safety of wastewater treatment processes, reducing manual labor and maintenance costs.

3 Ton Semi Gantry Crane in Metal Coil Processing Workshop

This 3 ton semi-gantry crane is used in a metal processing workshop for handling and transferring steel coils. The crane runs with one leg on a ground rail and the other side supported by a wall-mounted track, making full use of the available space inside the factory.

Equipped with an electric wire rope hoist, it provides smooth and precise lifting control for repetitive handling operations. This solution helps improve material flow efficiency and safety in confined production areas.

3 Ton Portable Gantry Crane for Vehicle Assembly Workshop

This 3 ton portable gantry crane is used in a vehicle manufacturing workshop to assist in the assembly and installation of chassis components. The crane features a lightweight steel structure and is equipped with an electric chain hoist for precise and stable lifting operations.

Thanks to its movable design with casters, the crane can be easily relocated across different workstations, allowing flexible lifting in confined spaces. It significantly improves assembly efficiency and reduces manual handling effort during vehicle component installation.

3 Ton Semi Gantry Crane for Efficient Pickling and Metal Surface Treatment

This 3 ton semi-gantry crane is installed in a metal surface treatment workshop and is specifically used for lifting and transferring workpieces during the pickling process.

The crane efficiently and safely hoists metal parts from one stage to the pickling tanks or subsequent processing stations, significantly improving operational efficiency while minimizing manual handling risks. Its robust, corrosion-resistant structure is designed to withstand the acidic environment, ensuring long-term reliable performance.

Structural Design of the 3 Ton Semi Gantry Crane

Huvudljus

The main beam is the primary load-bearing component of the hoist-type crane and also serves as the running track for the electric hoist. It is a box-type welded structure composed of a U-shaped channel (formed by cold bending Q345-B steel plates), inclined cover plates, stiffeners, and I-beams.

• The main beam is cambered upward according to design requirements, with a camber value F = (1/1000–1.4/1000) S, where S is the span.
• The maximum camber is positioned within the S/10 range at mid-span.
• The electric hoist trolley travels along the flange of the I-beam.
• When the rated load and hoist weight are positioned at the mid-span, the beam deflection does not fall below the horizontal line, ensuring no permanent deformation under normal working conditions.
• Shock absorbers are installed at both ends of the beam to ensure safe trolley operation.

Markbalk

The ground beam (or lower beam) supports both the main beam and the working load. It acts as the connection between the main beam and the travelling mechanism, serving as one of the crane’s key load-bearing structural components.

• Constructed from U-shaped channels and steel plates, it forms a box-type structure characterized by light weight, high rigidity, aesthetic appearance, and excellent weldability.
• Shock absorbers are also mounted at both ends of the ground beam for enhanced operational safety.

Supporting Legs

The supporting legs are welded from Q345-B steel plates into isosceles or right trapezoidal box-shaped columns.

Each leg features unequal-width flanges—a wider upper flange and a narrower lower flange—to improve strength, rigidity, and stability.

Structural Connection

• The main beam and legs are connected by bolted flanges, forming an A-frame structure that widens toward the base, greatly improving overall stability.
• The legs and ground beam are also bolted together via steel plate flanges, resulting in a simple structure that is easy to assemble, transport, and store.
