Logistics yards, railway freight stations, steel storage bases and inland container transfer stations have long been confronted with challenges in open-air material handling: reach stackers suffer from high fuel consumption and limited stacking height; forklifts occupy extensive passageways and have insufficient load capacity; simple lifting equipment features poor wind resistance and frequently causes cargo collisions and damages.
Yard gantry cranes are heavy-duty lifting equipment developed by Henan Mine Crane Group for outdoor open-air cargo yards. They mainly fall into two categories: Rail-Mounted Gantry Cranes (RMG) and Rubber-Tyred Gantry Cranes (RTG). Capable of handling containers, steel products, sectional materials, precast components and general bulk cargo, they provide an all-in-one solution to the pain points of material handling in open-air yards.
Three Major Industry Pain Points of Open-air Cargo Yards, Targetedly Solved by Henan Mine Yard Gantry Cranes
1. High wind loads for open-air operations lead to shaking during operation of ordinary lifting equipment
Wind conditions fluctuate greatly in uncovered outdoor environments. Simple gantry cranes feature insufficient rigidity, causing obvious swinging when lifting heavy loads. Containers and long steel materials are prone to tilting and scraping, resulting in cargo damage.
Henan Mine Crane Solution: Adopt thickened box girders and rigid outrigger structures, equipped with wind speed detectors, wind anchoring devices and rail clamps as standard; fitted with PLC frequency conversion anti-swing electric control to enable stable start and stop under strong wind conditions and reduce cargo swing amplitude.
2. Single type of handling equipment leads to high procurement and operating costs
Simultaneous operation of multiple reach stackers and forklifts incurs massive expenditures on fuel and operator labor. Idle equipment occupies yard space, leading to persistently low land utilization rate.
Henan Mine Crane Solution: One gantry crane for storage yards can replace 3 to 5 transport vehicles. Its overhead operation does not occupy ground passages, enabling dense stacking of goods in the yard. It eliminates long-term fuel costs and greatly reduces the number of on-site operators.
3. Erosion caused by open-air dust, rainwater and coastal salt mist leads to rapid corrosion of equipment.
Large temperature differences between day and night outdoors, together with continuous corrosion of steel structures by rainwater and dust, result in paint peeling and motor water ingress on ordinary cranes, bringing frequent maintenance and shortened service life.
Henan Mine Crane Solution: The whole machine is coated with epoxy zinc-rich heavy anti-corrosion paint; the electrical system is equipped with IP54 or higher dustproof and waterproof protection, and key bearings adopt sealed structures, enabling stable long-term operation in coastal and dusty freight yards.
Core Advantages of Trackless Cranes from Henan Mine Crane, Leading Similar Products in the Industry
As a benchmark enterprise in the crane industry, Henan Mine Crane Group leverages years of technological accumulation and integrates multiple core technologies into the R&D and production of trackless cranes to develop high-quality products featuring excellent flexibility, safety and durability with prominent core advantages.
1. Intelligent Configuration for Convenient and Efficient Operation
Equipped with an intelligent electric control system independently developed by Mine Hoisting, it supports three operation modes: wireless remote control, cab operation and wired handle control. Workers can flexibly select modes according to operation scenarios and conduct long-distance operations to stay away from high-risk working areas. Fitted with an intelligent fault diagnosis system, it can monitor equipment operating status in real time, provide early warnings of potential faults and reduce downtime, raising operation efficiency by over 30%.
2. Stable Heavy-load Performance Suitable for Various Harsh Working Conditions
The box-type main beam welded from high-strength steel boasts strong load-bearing capacity, easily handling heavy-load operations of 30 to 50 tons. Heavy-duty solid rubber tires paired with a high-strength suspension system enable stable and bump-free travelling on slightly uneven ground. Meanwhile, explosion-proof, low-temperature and highly anti-corrosion versions can be customized to meet customer requirements, adapting to special working scenarios such as chemical workshops, low-temperature cold storage and coastal ports.
3. Lightweight Design for Flexible and Labor-saving Transition
The optimized structural design achieves overall lightweighting while guaranteeing load-bearing performance, cutting the self-weight by 20% compared with similar products. Medium and light trackless cranes can be quickly disassembled and transported by small trucks for convenient transition. Heavy-duty RTG trackless cranes are equipped with a dual-power system. The mains cable reel saves energy and reduces noise during daily operation, while the vehicle-mounted diesel generator set handles transition and power outages, enabling non-stop all-weather operation.
Whether for heavy lifting in large outdoor storage yards or flexible transportation of small materials inside workshops, and whether for fixed locations or temporary operation scenarios, trackless cranes from Mine Crane Group can deliver precise adaptation. Boasting advantages of flexibility, high efficiency, safety, durability and cost-effectiveness, they help enterprises cut costs and boost efficiency.

FAQs
Q: What ground requirements apply to mining trackless cranes?
A: Only flat and hardened cement or asphalt ground is required, and the bearing capacity shall support the total weight of the equipment plus materials. Steel plates can be laid for operation on soft muddy ground. Operations on potholed or sloped sites are not recommended, as this will affect the operational stability of the equipment.
Q: Is the operating cost of trackless cranes higher than that of traditional rail-mounted cranes?
A: No. Trackless cranes require no rail installation, which saves substantial civil engineering costs. A single unit can replace 3 to 5 reach stackers or forklifts, greatly cutting labor and fuel expenses. Meanwhile, the equipment features low failure rates and low maintenance costs. Most customers can recover the equipment procurement cost within 1 to 3 years, making it more cost-effective for long-term operation.
Q: How is equipment warranty and after-sales service guaranteed?
A: The complete machine enjoys a 1-year warranty, while core components (motors, electric control systems and tires) come with an extended 2-year warranty. Multiple after-sales service outlets have been set up nationwide to provide on-site maintenance service within 48 hours. Overseas customers are offered lifelong remote video technical guidance. Original factory spare parts are permanently in stock to promptly resolve customers' after-sales issues.
