5t MGO European Double Girder Gantry Crane 6m Lift 18m Span USA

1. Product Overview

The MGO European-Spec Double Girder Gantry Crane is a high-performance lifting solution developed by Yuantai Crane. It is designed with a new NRT model European-spec electric crab hoist as the main lifting mechanism, combining advanced European design concepts with robust gantry crane structure.

The MGO gantry crane is engineered to deliver superior performance, safety and reliability, energy saving and high efficiency, low noise, and environmental protection. It is especially suitable for lifting and handling materials in workshops, warehouses, power stations, and other locations where bridge cranes cannot be installed.

Unlike a bridge crane that relies on runway beams mounted on building columns, the MGO gantry crane travels on ground rails or dedicated tracks. This makes it an ideal choice for indoor and outdoor material handling where building structures cannot support a traditional overhead crane system.

2. Lifting Mechanism: NRT European-Spec Electric Crab Hoist

The core lifting mechanism of the MGO gantry crane is the NRT model European-spec electric crab hoist. This hoist is designed according to European lightweight and modular principles, offering:

• Compact and optimized structure

• Smooth and precise lifting performance

• High working efficiency

• Low noise and low vibration

• Easy maintenance and serviceability

• Reliable braking and safety protection

The NRT electric crab hoist works together with the double girder gantry structure to provide stable lifting, cross travel, and long travel motions. It is suitable for heavy-duty and frequent material handling operations.

3. Applications

The MGO European-Spec Double Girder Gantry Crane has a larger lifting capacity and can perform most material handling tasks both indoors and outdoors.

Indoor Applications

For indoor use, the crane can be used in:

• Workshops

• Warehouses

• Factories

• Production lines

• Assembly areas

• Storage and logistics centers

• Power stations

• Maintenance and repair shops

It is ideal for moving raw materials, semi-finished products, finished goods, molds, equipment, and heavy components.

Outdoor Applications

For outdoor use, the MGO gantry crane can serve as the main lifting equipment with special lifting tools for:

• Goods loading and unloading

• Stone transfer

• Material handling

• Steel yards

• Mines

• Concrete industries

• Ports

• Shipbuilding

• Precast concrete yards

With appropriate lifting attachments, the crane can handle various types of loads, including hooks, grabs, magnets, spreaders, C-hooks, clamps, and other customized lifting tools.

4. Technical Specifications

5. Design and Structure

5.1 Box-Type Girder Design

The MGO gantry crane adopts a box-type girder design. This structure provides excellent rigidity, strength, and torsion resistance. The box girder is designed to withstand heavy loads and dynamic forces during lifting and traveling operations. It also allows for a compact overall structure and optimized dead weight.

5.2 Double Girder Gantry Structure

The double girder configuration provides a stable and strong platform for the electric crab hoist. It allows the crane to achieve larger lifting capacities and wider spans compared with single girder gantry cranes. The double girder design also improves the crane’s resistance to lateral forces and ensures smooth operation under heavy loads.

5.3 Gantry frame and Travel System

The gantry frame consists of main girders, legs, end carriages, and traveling wheels. The crane travels along ground rails, which makes it independent of the building structure. This is a major advantage in locations where bridge cranes cannot be installed.

The long travel and cross travel mechanisms are designed for stable movement, accurate positioning, and long service life.

5.4 Integrated Transmission

The MGO crane uses an integrated transmission design. This means the driving components are compactly arranged, reducing energy loss and improving transmission efficiency. The integrated design also simplifies maintenance and reduces the number of exposed parts.

6. Performance Features

6.1 European Design based on FEM / DIN Standards

The design of the MGO gantry crane is based on FEM / DIN standards. These internationally recognized standards emphasize safety, reliability, lightweight design, and high performance. The result is a crane that meets demanding industrial requirements while maintaining a compact and efficient structure.

6.2 Compact Structure and Small Limit Size

The crane has a compact structure and small limiting dimensions. This is especially important in workshops and warehouses where available space is limited. The compact design helps maximize the working area and improves the effective use of the facility.

6.3 Frequency Conversion Speed Regulation

The MGO crane adopts frequency conversion speed regulation, also known as VFD control. This provides:

• Stable starting and stopping

• Smooth acceleration and deceleration

• Precise load positioning

• Reduced mechanical impact

• Longer component life

• Lower energy consumption

Frequency conversion control makes the crane suitable for precise material handling and frequent operation.

6.4 Energy Saving and High Efficiency

The integrated transmission system, optimized structure, and advanced electric control work together to reduce energy consumption. The crane delivers high efficiency in lifting, cross travel, and long travel motions, helping users reduce operating costs.

6.5 Low Noise and Environmental Protection

The MGO gantry crane features a silent drive system. The gearboxes, motors, and transmission components are designed to minimize noise and vibration. This makes the crane more environmentally friendly and improves the working environment for operators and nearby personnel.

6.6 Safety and Reliability

Safety is a key design priority. The crane is equipped with a perfect protection device system to ensure safe and reliable operation. The structure, mechanisms, electrical system, and control system are all designed with safety in mind.
