‌RMG Type Double Girder Gantry Crane

Product Overview

The RMG double-beam tire gantry crane is a lifting equipment that combines a double-beam gantry crane with a tire-type traveling mechanism.

Its structural features include a double-beam gantry structure and a tire-type traveling mechanism, which enables the equipment to have high flexibility and adaptability while maintaining a high load-bearing capacity.

The RMG double-beam tire gantry crane is suitable for indoor and outdoor operations that do not require fixed tracks, such as construction sites, bridge construction, etc.

Due to its flexible tire-type traveling mechanism, it can operate on various terrains and is particularly suitable for environments with variable site conditions.

Depending on your actual use, there are different gantry cranes for customers to choose from.

We have an experienced team of crane engineers.

We design the right gantry crane system for you, and provide a full range of after-sales services to enable your crane to operate quickly, stably and reliably.

Key Advantages

This crane model is engineered for long service life and low maintenance in demanding industrial environments. Buyers choose it because it is built by the factory itself, with steel structure processed by CNC cutting and automated welding for dimensional accuracy and consistent quality.

• Reasonable structure and favorable performance.
• Smooth starting and stopping.
• Safe and reliable traveling, long life.
• Low noise, commodious cabin with good view.
• High quality automatic welding and NDT inspection
• Crane drive: IP54 or IP44, level F insulation
• Especially suitable for the container lifting.
• Designed according to your reques.

Main Features

Every ‌RMG Type Double Girder Gantry Crane leaves the factory complete with the following standard features, verified during final inspection and load testing:

• Flexible movement: Tire-type gantry cranes do not require fixed tracks and can move freely on flat ground, making them adaptable to a variety of working environments and needs, such as temporary construction sites, cargo yards, etc. It can be easily moved and turned within the construction site, improving work efficiency.
• Strong adaptability: The tire design enables it to adapt to different ground conditions, such as cement floors, soil, sand and gravel, which enables it to be used in a wider range of environments. No fixed foundation and site are required, and it can adapt to various environments and terrains.
• No need to fix tracks: No need to lay tracks, installation and disassembly are relatively simple, and it can be quickly deployed to different work sites, improving the efficiency and adaptability of use.
• Easy transportation and installation: The modular design makes it easy to transport and install, and the various components can be disassembled for transportation and assembled after arriving at the site, which enables it to be quickly put into use in a short time.
• Large load: The tire-type gantry crane has a strong lifting capacity and can adapt to different engineering needs. For example, the lifting capacity of a rubber-tyred container gantry crane is mostly 30t (tons), with a span of 6 rows of containers and the width of 1 transfer lane, and a lifting height of 4 over 5 (11-12 meters).
• High stability: The rubber-tyred gantry crane has strong stability and can effectively prevent the shaking of the lifting object. Its main components are made of steel, which has high strength and rigidity, ensuring its stability.
• High safety: The structure is compact and equipped with multiple safety systems to ensure the safety and stability of the operation.
• High operating efficiency: The rubber-tyred gantry crane can move forward and backward, and is equipped with a steering device. Through the 90-degree rotation of the wheel, it can be transferred from one container area to another for operation, which improves the loading and unloading efficiency.
• Simple maintenance: The structure is relatively simple and easy to maintain and repair. At the same time, the main components are made of steel, which has high corrosion resistance and wear resistance, and can well extend the service life of the rubber-tyred gantry crane.

Applications & Working Conditions

The ‌RMG Type Double Girder Gantry Crane is used across industrial plants, warehouses, steel mills, power stations, ports and logistics centers. It is available with optional lifting attachments such as lifting beams, electromagnets, grabs, C-hooks and coil tongs for special material handling.

Standard models operate in ambient temperatures from -20°C to +50°C. For special environments, we can supply explosion-proof electrics, high-temperature paint systems, dust-proof protection or corrosion-resistant coatings. Tell us your working condition and our engineers will confirm the correct configuration.

Customization Options

We customize span, lifting height, working class, control mode (pendant, wireless remote or cabin), and add frequency conversion speed control, explosion-proof protection or special coatings to suit your environment. Tell us your requirements and our engineers will prepare a tailored proposal.

Standard Supply Scope

Your order includes the complete crane structure, travelling mechanism, hoisting trolley or hoist, electrical control system, safety devices (limit switches, overload limiter, buffers, emergency stop), operation manual and inspection certificates. Optional extras include wireless remote control, frequency inverter, cabin with heater/air conditioner, lighting and special lifting attachments.

Quality Control & Testing

All structural welding is performed by certified welders and inspected before painting. Each crane undergoes no-load and full-load testing on our test bench, including brake test, limit switch verification and electrical safety check. Third-party inspection (SGS or buyer-nominated) is available before shipment.

Packing & Shipping

Cranes are shipped in knockdown form with steel structure, wheels, trolley, electrics and hardware carefully packed to prevent damage during ocean freight. Export packing follows our standard seaworthy specification, with wooden cases for electrics and control panels. Delivery options include FOB, CIF and DDP to your port.

Installation & After-Sales

We offer installation supervision and commissioning by our engineers, or fully turnkey installation by our experienced team. After commissioning we provide operator and maintenance training, a complete documentation package, and 24/7 spare parts and technical support for the lifetime of the crane.
