Export of GJM40.5t Rail‑mounted Container Gantry Cranes to Mongolia
Nation:Mongol Uls
A new container freight yard has been built at an international land border port in Mongolia, undertaking trans‑shipment, stacking and handling of standard containers for China‑Russia and China‑Mongolia cross‑border trade.
A new container freight yard has been built at an international land border port in Mongolia, undertaking trans‑shipment, stacking and handling of standard containers for China‑Russia and China‑Mongolia cross‑border trade. The local minimum winter temperature can reach ‑35℃, with frequent gales and sand‑dust weather all year round and huge day‑night temperature differences in the open‑air yard. Conventional container cranes are prone to steel cold brittleness, electric control icing and paint abrasion by wind‑blown sand. The port operates 24/7 customs clearance, imposing strict requirements on heavy‑load stability, low‑temperature weather resistance and continuous operation capacity.
After comparing multiple domestic crane manufacturers and conducting on‑site inspections on Henan Dafang Heavy Machinery’s production capacity, complete foreign‑trade delivery capability and low‑temperature equipment cases, the port operator placed a batch order for multiple GJM40.5t rail‑mounted container gantry cranes. Taking full account of Mongolia’s frigid and sandy conditions, cross‑border customs clearance & transport constraints and handling requirements for 20ft / 40ft standard containers, Dafang engineers carried out targeted optimizations on low‑temperature steel structures, wind‑proof anti‑corrosion electric control and dedicated container spreaders. The batch of export‑oriented gantry cranes was completed within a 72‑day manufacturing cycle. Modular‑packed units were transported by road to the Mongolian port yard. On‑site assembly, load test and port safety acceptance were completed in one go, and the equipment was officially put into cross‑border container stacking and trans‑shipment service.
Project Execution & Solution Overview
Dafang supplied multiple sets of GJM40.5t rail‑mounted container gantry cranes for this project. Key project milestones and engineering solutions are listed below:
Supplier Field Evaluation & Equipment Selection
The port operator compared multiple domestic crane manufacturers and conducted on‑site inspections of Dafang’s production capacity, complete foreign‑trade delivery capability and proven low‑temperature equipment cases, and finally placed a batch order for GJM40.5t rail‑mounted container gantry cranes.
Customized Solution Optimized for Mongolian Working Conditions
Taking into account local ‑35℃ frigid and sandy climate, cross‑border customs clearance & transport constraints, as well as 20ft / 40ft standard container handling requirements, Dafang engineering team carried out targeted optimizations on low‑temperature steel structure, wind‑proof anti‑corrosion electric control and dedicated container telescopic spreader.
72‑day Mass Foreign‑trade Equipment Manufacturing & Inspection
The batch‑produced export‑oriented container gantry cranes were completed within a 72‑day manufacturing cycle. The whole unit was disassembled and packed in modular export packages to meet protection requirements for long‑distance cross‑border road transportation.
Turn‑key Port‑site Deployment & Commissioning
Equipment was transported by road to the Mongolian port yard. On‑site assembly, load test and port safety acceptance were completed in one go. The cranes were officially put into operation for cross‑border container stacking and transshipment.
Core Technical Features & Advantages
Low‑temperature Thickened Box‑type Main Girder: Resist ‑35℃ Extreme Cold without Brittle Fracture
The crane adopts heavy‑duty double box‑girder construction. Main girders and legs are made of Q355E low‑temperature impact‑resistant steel plates passing ‑40℃ low‑temperature impact tests for Mongolia’s frigid open‑air winter conditions. All load‑bearing welds are 100% ultrasonically inspected. Rated A6 high working class, it can lift 40.5t full‑loaded containers 24/7 with zero risk of cold‑brittle cracking under low‑temperature heavy‑load conditions. The crane features Dafang’s signature red heavy‑duty anti‑corrosion finish with four‑layer weather‑resistant polyurethane topcoat against sand abrasion and UV aging to avoid peeling and fading in long‑term outdoor service. Ladders, maintenance platforms and fasteners are all hot‑dip galvanized for rust protection.
Grade‑8 Wind‑resistant Structure for Perennial Border Gales
The widened and thickened leg support frame plus optimized travelling‑base counterweight delivers official Grade‑8 wind‑resistance. The travelling mechanism can be locked in high wind to prevent sliding or overturning. Full‑enclosed perimeter maintenance walkways and guardrails on top ensure safe high‑altitude maintenance under strong wind. Dual‑brake wind‑proof rail clamps for travelling mechanism automatically grip rails at standstill to eliminate equipment displacement caused by sudden port gusts.
Fully‑sealed Dust‑proof Low‑temperature Electric Control for Stable Operation in Frigid & Sandy Conditions
The complete electrical system is specially upgraded for extreme cold and sand‑dust: IP65 control cabinets with built‑in auto constant‑temperature heating modules activate heating below 5℃ to avoid internal condensation icing and electronic component failure. Motors are fitted with low‑temperature‑resistant insulating windings together with cold‑resistant flexible special cables that will not harden or crack under sub‑zero temperatures. Sand‑proof sealed inverters and contactors together with multi‑layer dust filters block fine border sand ingress and prevent short‑circuit shutdowns. Dual‑control modes (cab centralized control + wireless remote control) with Mongolian‑English bilingual HMI are provided for local operators.
Dedicated Telescopic Spreader for Automatic Positioning of 20ft / 40ft Standard Containers
Equipped with Dafang self‑developed 40.5t telescopic container spreader, which automatically telescopes for 20ft and 40ft marine containers with four‑corner twist‑lock automatic locking to hold containers without offset or dropping. Built‑in load monitoring and anti‑unlocking alarm feed real‑time no‑load / full‑load status to the cab display. Spreader pulleys and pins are made of low‑temperature wear‑resistant alloy; grease remains fluid in severe cold to cut frequent maintenance downtime and greatly improve port container handling turnover efficiency.
On-Site Delivery & After-Sales
Multiple GJM container gantry cranes are disassembled into separate modules: main girders, legs, trolley, container spreader and electric control units. Components are packed with rain‑proof rust‑proof wrapping film plus solid‑wood export cases to avoid collision and sand erosion during long‑distance cross‑border land transport. Our dispatched professional installation engineers stay on‑site at the Mongolian port to complete full‑scope work including unit assembly, rail alignment, spreader joint commissioning and full‑load container testing. Complete export customs‑clearance documents are supplied: material & NDT reports, third‑party load test certificates, certificate of origin, CE certificates and bilingual operation & maintenance manuals to assist customers with Mongolian industrial‑equipment import filing.
After delivery, hands‑on training is delivered for local maintenance teams covering startup‑shutdown specifications under extreme cold, dust‑proof maintenance for sandy conditions and spreader twist‑lock servicing. Year‑round multi‑language remote technical support is available. Original spare parts including low‑temperature motors, electric‑control parts and spreader components can be exported in batches to guarantee non‑stop container customs‑clearance operations at the land port all year round.
Summary
The batch‑shipped GJM40.5t rail‑mounted container gantry cranes for Mongolian ports are special‑purpose export cranes developed by Dafang Heavy Machinery for windy, frigid land border ports. Featuring four core strengths: low‑temperature steel structure, Grade‑8 wind‑resistance, bilingual intelligent electric control and standard container telescopic spreader, they perfectly solve container‑handling challenges in Mongolia’s cold and sandy yards.
