Henan Mine Crane Double girder electric hoist gantry crane Product Introduction
Henan Mine Crane Double Main Girder Electric Hoist Gantry Crane is a heavy-duty general-purpose gantry crane developed in strict compliance with the standard of electric hoist gantry crane, with high-quality electric hoist as the hoisting mechanism, double main girder box structure and bilateral outrigger support design, can complete the vertical lifting and lowering of the material, longitudinal and lateral movement.
Outriggers can be cantilevered to expand the operating range, can also be designed without cantilever, suitable for heavy-duty, large-span material handling needs, Henan Mine Crane for heavy-duty handling scenarios to create a cost-effective double girder gantry lifting main products.
This double girder electric hoist gantry crane for the global heavy-duty operation scenarios to do special optimization: double girder structure compared to the single girder hoist gantry bearing stronger, more stable operation;
Sitting hoist running trolley, higher lifting height than directly suspended hoist; electric hoist as the hoisting mechanism, compared with the winch mechanism double girder gantry, lower procurement costs, routine maintenance is easier, is the preferred double girder gantry lifting solutions for global heavy-duty material handling.
1. Product core positioning and design standards
The core positioning of MHS double girder electric hoist gantry cranes is to provide customers around the world with double girder gantry lifting solutions that are heavy-duty and stable, with high lifting capacity and low cost and easy maintenance. Designed in line with China’s national industry standards for electric hoist gantry cranes, synchronized with the international FEM, EU CE, ISO standards, for the four core pain points of “heavy-duty load bearing, large-span stability, high lifting requirements, low maintenance costs”, the use of double girder rigid structure and sit-down electric hoist configuration to meet the regular heavy-duty intermittent operations, suitable for the global indoor workshop, high lifting requirements, and low cost and easy maintenance. It is suitable for indoor workshops, outdoor yards, port terminals and other heavy-duty handling conditions around the world.
2. Core structure and function design
- Heavy-duty structure of double main girder: Adopting rigid design of double main girder box, with even load distribution, strong bending and torsion resistance, compared with single girder hoist gantry, the carrying capacity and stability are greatly improved, and there is no obvious deformation and shaking during heavy-duty operation, so it is suitable for large-tonnage material lifting.
- Sitting hoist lifting mechanism: Sitting hoist running trolley layout, different from the direct hanging hoist, effectively improves the effective lifting height of the whole machine, which is suitable for the demand of high headroom operation and makes full use of the vertical space in the workshop/freight yard.
- Cost-effective lifting configuration: Using the mature electric hoist as the lifting mechanism, compared with the wire rope winch double girder gantry, the machine has a lower procurement cost, simpler structure, more convenient maintenance, and does not require complex maintenance processes, reducing the cost of the whole cycle of use.
- Flexible cantilever configuration: the outboard side of the outrigger can be equipped with cantilever structure to realize the transfer of materials from inside the span to outside the span, expanding the operating range; the cantilever can also be canceled to adapt to the narrow operating space, which is more adaptable to the site.
- Smooth running mechanism: the traveling mechanism runs smoothly and has no impact when starting and stopping, together with the rigid structure of double main beams, the material is accurately positioned in the process of lifting and transporting, avoiding collision of materials and wear and tear of the equipment, and improving the safety of operation.
- Generalized control system: support handle control, wireless remote control, driver’s room control multiple modes, simple and easy to understand the operating logic, adapt to different operating habits and scenarios, ordinary workers can be operated independently after simple training.
3. Core product advantages
- Heavy load and high stability: double main beams have strong structural rigidity, the carrying capacity and operational stability far exceeds that of single beam models, heavy lifting without deformation and shaking, safer operation.
- High lifting adaptability: sitting hoist trolley design, effective lifting height is higher, to meet the needs of high headroom, high vertical lifting, to enhance the site utilization rate.
- Low cost and easy maintenance: electric hoist lifting mechanism, simple structure, common accessories, convenient maintenance, procurement and operation and maintenance costs are much lower than the winch type double girder gantry.
- Wide site adaptation: cantilever/no cantilever options, indoor and outdoor universal, suitable for factories, yards, ports, steel markets and other scenes of heavy-duty handling.
- Global adaptability and easy to export: support international certification, global power grid customization, standardized design and strong compatibility, can be directly exported around the world.
4. Global Adaptation and Application Scenarios
- Application Scenarios: Global machining workshop, logistics and storage park, steel market, harbor yard, hydropower station, building materials processing plant, etc., used for loading, unloading, handling and shifting of heavy materials such as heavy components, steel, equipment and bulky goods.
- Standard adaptation: Support CE, ISO9000, GOST, FEM and other international certifications, power supply 220V-660V/50-60Hz is fully customized, adapted to global power grid standards.
