Before leaving the factory, rubber-tyred cranes (including RTGs, port-specific rubber-tyred cranes, and mobile rubber-tyred cranes) must undergo a full-process testing regimen in accordance with national standards such as GB/T 6068-2021. This testing covers every dimension—including appearance, structure, chassis, hydraulics, electrical systems, safety, load capacity, stability, travel performance, and reliability. The following outlines the complete testing procedures, which are suitable for direct use in quality inspection protocols and technical tender specifications.

The core strategy consists of the following: front-loading order reviews, locking down material specifications, maintaining rigid production scheduling, standardizing process cycle times, and rapidly resolving anomalies.

What Information Is Needed When Requesting a Quote for Lifting Gear from a Manufacturer?

Low-voltage rail-powered industrial electric transfer flatcars (KPD series) are the preferred choice for heavy-duty, long-distance, fixed-route, and continuous operation scenarios. Their core advantages are unlimited battery life, safe low-voltage operation, no cable drag, and stable performance under heavy loads.

The grab-type double-girder overhead crane is primarily designed for handling bulk materials; it features automated loading and unloading capabilities and eliminates the need for manual hooking. Its application scenarios are highly focused, centering mainly on the handling of loose bulk materials, loading and unloading operations in stockyards, and internal material transfer within workshops and warehouses.

I. Product Introduction
The electric tow tractor (also known as an electric tugger or tow head) is a compact industrial towing device powered by a rechargeable battery. It is primarily used within factory premises to tow various types of flatbed trailers, material cage trailers, and similar equipment, facilitating the efficient transfer of raw materials, molds, and finished or semi-finished goods. It is widely utilized across industries such as die casting, mechanical manufacturing, warehousing, and automotive parts production.

Common faults in RTG (Roller-Tracked Toy) cranes are concentrated in five major systems: hydraulic, traveling/steering, hoisting/luffing, electrical, and tires/outriggers. Emergency handling follows the principle of first stopping the machine to avoid danger, then investigating the root cause, and finally restoring safety.

RTGs (Rubber-Tyred Gantry Cranes) are classified across five core dimensions: main girder structure, leg frame configuration, power system, degree of automation, and operational function. They are utilized in various settings, including ports, container yards, and precast concrete plants. The following outlines the mainstream types and key selection criteria:

Export Loading Methods for Rubber-Tyred Gantry (RTG) Cranes?
The export loading of Rubber-Tyred Gantry (RTG) cranes primarily utilizes the "Roll-on/Roll-off" (Ro-Ro) method for complete units, supplemented by "Lift-on/Lift-off" (Lo-Lo) for complete units. Smaller or specialized models may be disassembled for segmented transport, accompanied by professional lashing and packaging solutions.

The core advantage of the four-hoist mobile gantry crane (or "four-hoist tire crane") lies in its capabilities for multi-point synchronous lifting, load leveling for long or large-surface workpieces, and coordinated operation across multiple lifting points. It is particularly well-suited for the handling and installation of heavy loads that are long, large, thin, prone to deformation, or require uniform force distribution across multiple points.
