15 tons single girder gantry crane offers stable performance, easy installation and low maintenance. Customizable medium-duty lifting equipment, ideal for construction, machinery, port yard and outdoor material handling with high safety and cost efficiency.
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.
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.
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.
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.
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.
This series of gantry cranes follows international industrial standards, with standardized and reliable core parameters to meet medium-duty industrial operation requirements:
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.
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.
The 15 tons single girder gantry crane is a versatile medium-duty handling equipment, widely used in various industrial fields:
Safety is the core design priority of this gantry crane. It is equipped with comprehensive safety protection devices including overload limiter, height limit switch, traveling limit switch, emergency stop button and anti-collision device to prevent overloading, overtravel and accidental collision risks. All products are manufactured in strict accordance with international crane industry standards, with each production link undergoing strict quality inspection, including welding quality detection, load test and overall performance test. The whole machine features stable operation, low failure rate and high safety factor, meeting long-term continuous industrial operation requirements.
