Gantry crane
MG Type Double Girder Gantry Crane | Heavy-Duty, Outdoor, CE-Compliant
Product Overview
The MG Type 40-Ton Double Girder Gantry Crane is a powerful and robust material handling system engineered for heavy-duty outdoor applications. This rail-mounted gantry crane features a classic double-girder A-frame design, providing exceptional strength and stability for lifting and moving substantial loads. It operates on ground-level rails, delivering extensive lifting coverage across stockyards, construction sites, and industrial facilities without the need for a supporting building structure. With its high-performance hoist, durable construction, and weather-resistant features, the MG Type crane is a reliable workhorse for your most demanding lifting challenges.
Product Advantages
- Robust Heavy-Duty Performance: Built to an A5-A6 work duty classification, the MG Type crane is designed for frequent, heavy lifting. Its strong double-girder frame ensures superior load stability and long-term structural integrity.
- Ideal for Outdoor Environments: With an IP55 protection rating, a multi-layer anti-corrosion paint system, and weather-resistant components, this crane is built to withstand the rigors of outdoor use, including rain, dust, and wind.
- Powerful and Efficient: A high-capacity hoist and powerful travel motors deliver efficient lifting cycles. The system can be configured with two-speed controls or advanced Variable Frequency Drives (VFDs) for smooth, precise handling of 40-ton loads.
- Cost-Effective Infrastructure: As a ground-based system, it eliminates the need for an expensive indoor runway and building support columns, offering a lower total investment for heavy lifting capability over a large area.
- Enhanced Safety as Standard: Equipped with a full range of safety features, including overload limiters, rail clamps, an anemometer for wind-speed monitoring, and anti-collision devices, ensuring maximum operational safety.
Application Scenarios
- Precast Concrete and Construction Yards: Perfectly suited for lifting and moving large precast beams, panels, and other heavy construction materials with power and precision.
- Outdoor Steel Stockyards: An essential tool for handling heavy steel coils, plates, structural sections, and pipes in open-air storage and processing facilities.
- Port and Rail Terminals: Efficiently handles heavy cargo, machinery, and containers for loading and unloading operations in logistics and transshipment hubs.
- Heavy Manufacturing: Provides powerful lifting support for assembling large equipment and moving heavy fabrications in outdoor assembly areas.
- Bridge and Infrastructure Projects: Used in laydown yards for handling large girders, segments, and other major components during bridge construction.
