This project involves the custom delivery of a 40.5-ton, 17.5-meter-span RMG rail-mounted gantry crane for a freight hub in Mongolia. The RMG crane to Mongolia utilizes low-temperature steel and a cold-resistant electrical system, enabling stable operation in extreme cold environments down to -40°C.

Equipped with PLC automatic control and a remote operation and maintenance system, RMG crane can significantly enhance operational efficiency by 30-50%. This project serves as a flagship example of our company’s intelligent, weather-resistant lifting equipment entering the Central Asian market.

Mongolian RMG Crane Project Overview

Recently, Dafang company successfully delivered an RMG rail-mounted container gantry crane to Mongolia. The main technical specifications are as follows:

Challenge: Reliable Operation in Extreme Cold

Located on an inland plateau, Mongolia experiences winter temperatures as low as -40°C, posing severe challenges to the material properties, sealing performance, and lubrication systems of the equipment.

To address this, our company implemented the following customized solutions:

• Low-Temperature Steel: The main structure utilizes Q345E low-temperature steel, with impact toughness meeting -40°C operating conditions to eliminate the risk of cold brittleness;
• Low-Temperature Lubrication System: The entire machine is equipped with low-pour-point grease and an automatic centralized lubrication system to ensure smooth mechanical operation under extreme cold conditions;
• Cold-Resistant Electrical Configuration: Control cabinets are fitted with heating devices, and low-temperature flexible cables are selected to ensure the stability of the electrical system;
• Wind and Snow Protection Design: Walkways, guardrails, and critical structural joints have all undergone snow-load calculations to ensure structural safety.

Highlights: High Automation, Reduced Reliance on Manual Labor

Given the relative scarcity of specialized operators in Mongolia, this project prioritizes enhancing automation levels:

• PLC Centralized Control: Utilizes a Siemens PLC system to achieve precise coordinated control of the three major mechanisms: hoisting, gantry, and trolley;
• Anti-Sway System: Electronic anti-sway technology effectively suppresses lifting device sway, improving operational safety and efficiency;
• Remote Monitoring: Equipped with real-time data acquisition and remote diagnostic interfaces to support remote maintenance by the manufacturer, reducing after-sales response times;
• Fault Self-Diagnosis: The system automatically identifies common faults and issues alarm notifications, minimizing downtime losses.

Delivery and Outcomes

Since its commissioning, the equipment has maintained stable, fault-free operation under Mongolia’s harsh winter conditions, with loading and unloading efficiency improved by approximately 30% compared to traditional equipment, earning high recognition from the client.

This project serves as an essential case for Хэнань Дафан Хэви Машине Ко., Лтд.’s “weather-resistant intelligent lifting equipment” exported to the Central Asian market, fully demonstrating the product’s comprehensive competitiveness in extreme climates and scenarios requiring automation.

Q1: What is the lowest temperature this equipment can withstand?

A: The equipment has undergone specialized low-temperature design. The main structure uses Q345E low-temperature steel, and both the lubrication and electrical systems have been validated for operation at -40°C. It can operate stably over the long term under Mongolia’s typical extreme winter conditions without requiring shutdown for protection.

Q2: What is the level of automation? Is on-site professional operation required?

A: The equipment is equipped with Siemens PLC centralized control and an electronic anti-sway system, making operation simple. It also supports remote diagnostics and maintenance, ensuring efficient and safe daily operations even with limited local technical resources.

Q3: Can the 17.5-meter span be customized?

A: Yes. We can flexibly customize the span, lifting height, and jib length based on the customer’s yard layout, track gauge requirements, and operational processes to meet the specific needs of different railway freight yards or port yards.

Q4: How are the equipment delivery timeline and overseas installation ensured?

A: The standard production cycle is approximately 90–120 days. We provide full technical support, including dispatching engineers to the site to guide installation and commissioning, as well as providing operator training, to ensure the equipment is successfully put into operation.

Q5: How are after-sales service and spare parts supply handled?

A: We have a remote monitoring and fault diagnosis system in place to support online technical assistance. Additionally, we provide customers with critical spare parts kits and establish regional spare parts warehouses to ensure timely component supply and minimize the risk of downtime.
