This drawing covers a 50-ton Rail-Mounted Gantry (RMG) Container Crane, model RMG50t(Incl. Spreader)-19m-15m Cantilevers 5m A6, drawing number RMG50-20 A6, built by Yuantai Crane Machinery. The crane has a 19.0 m span, a 15.0 m lifting height, and a total bridge length of 37.0 m including 5.0 m effective cantilevers on both sides. It is equipped with a telescopic container spreader for handling both 20 ft and 40 ft ISO standard containers.
The crane uses dual operation modes: cabin control (operator room) and wireless ground remote control. This combination gives the yard more flexibility in daily operations. The crane is rated ISO A6 duty with M6 mechanisms, and runs on QU80 heavy rails. Speeds are: full-load lifting 2.5–14.5 m/min (no-load 5.0–29 m/min), trolley travel 3.2–18.8 m/min, and gantry travel 4.8–28.9 m/min. It is designed for container terminals, railway freight yards, and logistics centers.

Engineering Standard Notes:
- Design & Manufacturing Standards: The design, manufacturing, installation, inspection, and acceptance of this crane shall comply with GB/T19683 standards.
- Insulation Resistance Testing: When measuring the ground insulation resistance and inter-phase resistance of electrical equipment, all circuits of the main and control systems must be connected, and the resistance value shall not be less than 0.5 MΩ (a 50% reduction is permitted in humid environments).
- Grounding Safety Protection: All metal enclosures of electrical equipment on the crane must be reliably grounded. Crane rails may be used as grounding conductors, and plant steel structures can also serve as grounding paths.
- Drawings & Copyright: These drawings and parameters are provided for engineering reference only. Unauthorized copying or commercial manufacturing without written authorization from Yuantai Crane Machinery is prohibited.

Common questions about the 19 m compact span design, telescopic spreader application, and dual-control modes.
The 19 m span is designed for width-restricted container yards or narrow rail corridors. Combined with 5 m symmetric cantilevers on each side, it covers traffic lanes and storage blocks within a total length of 37 m, balancing a large working envelope with efficient land use.
The telescopic spreader adjusts its length automatically through hydraulic or electric actuation, switching between lifting 20 ft and 40 ft ISO standard containers without manual attachment changes. This improves container yard loading and unloading turnover efficiency.
The cabin control system provides wide visibility for all-weather, high-intensity continuous operations, while the portable wireless remote allows ground operators to perform precise hook and unhook maneuvers and local positioning in specific zones. Together they combine high efficiency with operational flexibility.
ISO A6 represents heavy-duty service (M6 mechanisms), designed for medium to high frequency container terminals. It keeps the crane at low failure rates and high uptime under years of high-intensity full-load and frequent start-stop cycles.
