55 Ton dubbelbalk-portaalkraan

Produk Oorsig

Die 55 tons double girder gantry crane is a heavy-duty, high-efficiency industrial material handling solution engineered for large-load, continuous and high-frequency lifting operations. Adopting a robust double main girder structural design, this gantry crane features outstanding rigidity, superior load-bearing capacity and excellent operational stability, effectively overcoming the load limitations of single-girder gantry cranes. Different from overhead cranes, it runs on ground-mounted rails, requiring no factory roof support, which makes it highly adaptable for outdoor yards, open workshops, port terminals and large construction sites.

Manufactured in strict accordance with international FEM and national industrial standards, this 55-ton gantry crane integrates mature mechanical structure, advanced electrical control system and comprehensive safety protection devices. It is capable of stably lifting and transporting heavy materials such as steel structures, mechanical equipment, prefabricated building components and container cargo, serving as core handling equipment for heavy industrial production and engineering construction.

55 Tons Double Girder Gantry Crane Standard Technical Parameters

55 Tons Double Girder Gantry Crane Core Features

1. Ultra-Stable Heavy-Duty Structure

Equipped with high-strength box-type double girders, the crane adopts optimized welding technology and integral stress relief treatment, which effectively eliminates structural deformation caused by long-term heavy-load operation. The reinforced leg structure and anti-tilting design greatly enhance the overall rigidity and wind resistance, ensuring zero jitter and stable operation even under full 55-ton load conditions. The whole machine features high fatigue resistance, meeting the long-term continuous operation demands of heavy industrial scenarios.

2. Hoë-doeltreffendheid & Presiese werking

This gantry crane is configured with variable frequency speed regulation systems for lifting, trolley traveling and crane traveling. It realizes stepless speed adjustment, avoiding sudden start and stop impact, verseker gladde opheffing, translation and positioning of heavy loads. With accurate positioning accuracy, it effectively improves operation efficiency and reduces material collision and positioning errors. The dual-control mode of driver’s cabin and wireless remote control supports flexible operation according to on-site working conditions, adapting to diverse operating habits and complex working environments.

3. Sterk omgewingsaanpasbaarheid

Designed for all-weather industrial operation, the crane can work stably in a temperature range of -10℃ to 45℃, adapting to harsh outdoor environments such as high temperature, low temperature and dust. It is equipped with an excellent wind-proof system, which can resist strong wind of 55m/s, effectively preventing equipment tilting and sliding in windy weather. Two power supply modes, cable power supply and sliding contact line power supply, are optional to meet different on-site power source configurations and layout requirements.

4. Lae onderhoud & Lang Diens Lewe

Key components such as lifting winch, traveling reducer and walking wheels adopt international high-quality accessories, with stable performance and low failure rate. The structural parts are treated with anti-rust paint and galvanization, enhancing corrosion resistance and wear resistance, suitable for long-term outdoor open-air use. The modular design simplifies daily inspection, onderhoud en vervanging van onderdele, greatly reducing later operation and maintenance costs and downtime losses.

Omvattende veiligheidsbeskermingstelsel

Safety is the core design priority of this 55-ton double girder gantry crane, which is equipped with a full set of mechanical and electrical safety protection devices to eliminate operational risks in all aspects:

• ◆ Oorladingsbeskerming: Automatic power-off and alarm when the load exceeds the rated weight, avoiding equipment damage and safety accidents caused by overload operation.
• ◆ Limit Protection: Equipped with lifting height limit, traveling limit and buffer devices to prevent over-travel and collision accidents.
• ◆ Wind-Proof & Anti-Slip Devices: Configured with wind speed alarm, manual/electric anchoring and rail clamping devices to ensure stable parking in strong wind.
• ◆ Noodstopstelsel: Independent emergency stop button to cut off power immediately in case of abnormal conditions for rapid risk control.
• ◆ Anti-Sway Technology: Effectively reduce load swing during operation, improving running stability and operation safety.
• ◆ Fasevolgorde & Oorspanning/Onderspanningbeskerming: Protect electrical system from damage caused by abnormal power supply, ensuring stable electrical operation.

55 Tons Double Girder Gantry Crane Application Scenarios

With its heavy-load capacity, wide coverage and strong environmental adaptability, die 55 tons double girder gantry crane is widely applicable for various heavy industrial lifting scenarios:

• ◆ Steel plants, machinery manufacturing factories (handling steel plates, large mechanical equipment, metal profiles)
• ◆ Construction engineering sites (lifting prefabricated components, boumateriaal, engineering machinery)
• ◆ Port terminals, vragwerwe (loading and unloading bulk cargo, containers and heavy goods)
• ◆ Skeepswerwe, hydraulic engineering projects (handling ship accessories, hydraulic equipment)
• ◆ Large outdoor warehouses and logistics yards for heavy-duty material turnover
