15 Tons Single Girder Gantry Crane

The 15 tons single girder gantry crane is a medium-duty material handling solution engineered for efficient, stable, and cost-effective lifting operations. Adopting a mature MH-type single box girder structure, this crane integrates a streamlined mechanical design with reliable electrical control systems, perfectly balancing lightweight construction and robust load-bearing capacity. Designed for 15-ton rated lifting tasks, it is widely applicable for outdoor and semi-outdoor material lifting, loading and unloading, and workpiece handling across industrial yards, construction sites, warehouses, and processing factories. Compared with double girder gantry cranes, this single girder model features a simpler structure, lighter self-weight, lower installation and maintenance costs, and higher space utilization, making it an ideal choice for medium-frequency and medium-load lifting scenarios.

Core Product Features & Advantages

1. Optimized Structural Design

The main girder is fabricated with high-quality Q235B carbon structural steel through integral welding and stress elimination treatment, ensuring high rigidity, strong toughness, and anti-deformation performance under long-term working conditions. Optional box-type and truss-type girder structures are available: the box-type girder delivers stable operation and easy processing, while the truss-type design reduces self-weight and enhances wind resistance, adapting to different outdoor working environments. The overall structure is compact with a reasonable force-bearing layout, effectively reducing ground foundation pressure and lowering site construction requirements.

2. High Efficiency & Energy Saving

Equipped with a matched electric hoist as the lifting core component, the crane realizes stable vertical lifting and horizontal traveling. It adopts variable frequency speed regulation technology as standard, enabling smooth start, acceleration, deceleration and stop without impact and swing, which greatly improves operation accuracy and handling efficiency. The optimized transmission structure reduces mechanical friction loss, and the low-power matching motor effectively cuts down energy consumption and operating costs compared with traditional heavy-duty cranes.

3. Easy Installation & Low Maintenance

With fewer structural components and a modular assembly design, the 15-ton single girder gantry crane is simple and fast to install and debug, shortening project commissioning cycles. All wearing parts and key components are designed for easy disassembly and replacement. The surface adopts three-layer anti-corrosion painting treatment, which resists rust, abrasion and outdoor weather erosion, greatly extending the service life and reducing daily maintenance workload and long-term operating costs.

4. Strong Adaptability & Customization

The crane supports multiple customized configurations to meet diverse site demands. It can be designed with single-side or double-side cantilevers to expand the effective working range without increasing the main span, realizing flexible material handling beyond the crane’s supporting legs. Customizable span, lifting height, traveling speed and working modes are available to adapt to narrow workshops, open yards and special working sites.

Main Component Configuration

1. Main Mechanical Parts

The complete machine consists of main girder, rigid and flexible supporting legs, end carriages, electric hoist, traveling mechanism and buffer devices. The walking wheels are made of high-strength alloy steel with wear resistance and pressure resistance, ensuring stable traveling without derailment. The high-performance buffer effectively eliminates impact force during extreme position operation, protecting the crane body and on-site equipment.

2. Electrical Control System

Adopting mature and stable electrical control components with insulation protection design, the system features sensitive response and stable performance. The variable frequency control system realizes stepless speed regulation, avoiding cargo swing and ensuring precise positioning during lifting and handling. The circuit is equipped with overload protection, limit protection, short-circuit protection and emergency stop devices to ensure safe and standardized operation.
