1. Product core positioning and design standards

The core positioning of QYE double trolley insulated overhead travelling crane is to provide “insulated safety + flexible and efficient” special lifting solutions for the global strong current, high temperature and corrosive environment, and the design is strictly in accordance with GB/T 14405-2011 “General Overhead Travelling Crane” and JB/T 10219-2001 “Explosion-proof Crane” (insulation special standard). The design strictly follows GB/T 14405-2011 “Universal Overhead Crane” and JB/T 10219-2001 “Explosion-proof Girder Crane” (special standard for insulation), and is compatible with the international IEC, EU EN and other requirements of the certification system for insulated lifting equipment, which is aimed at the safety of high-voltage electrified operation scenes

2. Core structure design

The whole machine structure is designed around the three core requirements of intelligent operation of double trolleys, multiple insulation protection and high-precision speed regulation. It is a special modularized assembly structure, with the core composed of three key parts, and the structures work together to realize safe, flexible and accurate lifting in special environments:

2.1 Dual trolley intelligent operation mechanism: the whole machine is equipped with dual independent trolley operation system, with high synchronization and accurate positioning, which effectively solves the demand for flexibility of multi-tonnage material lifting in special environments, and the trolleys and the main beams are made of abrasion-resistant and corrosion-resistant materials at the articulation place, which is suitable for high-frequency operation in high temperature and corrosive working conditions.

2.2 Multi-insulation protection structure: high strength insulating pads are installed between the lifting mechanism, and the connection parts are equipped with insulating sleeves and insulating plates, forming an all-around insulating barrier between the machine body and the electrified body, completely blocking the leakage current conduction, and guaranteeing the safety of the operators and the equipments.

2.3 High-precision drive and speed regulating mechanism: Equipped with high-precision drive system and stepless speed regulating device, the lifting and running actions can realize smooth speed regulation, and the lifting and running speeds can be adjusted accurately according to the operational requirements, avoiding damages to the surrounding high-voltage equipments and precision parts.

2.4 Environment-resistant bearing structure: the main beam is made of high-quality high-strength steel welding molding, non-destructive testing and stress relief treatment, high-temperature spraying on the surface, anti-corrosion and anti-rust treatment, deformation resistance and strong corrosion resistance.

3. Core product advantages

As a high-voltage environment insulated crane specially designed for strong current, high temperature and corrosive scenes, its core advantages revolve around multiple insulation safety, double trolley flexible operation, precise and smooth lifting, strong environmental adaptation, which is also its core highlights that distinguish it from the traditional single trolley insulated overhead travelling crane:

3.1 Multiple insulation protection, safe in high-voltage environment: all-round insulation design, with high-voltage-resistant special materials, completely blocking the leakage current conduction, insulation performance far exceeds the industry standard, can be safe in strong current, high-voltage energized environment, from the root to avoid electrocution, short-circuiting and other safety risks, is a high-voltage scenario of the safety of the lifting guarantee.

3.2 Dual trolley separate/joint operation, adaptable to multi-tonnage demand: large tonnage of heavy materials can be dual trolley joint operation, load sharing, synchronous operation, a device to meet the full tonnage from light to heavy lifting needs.

3.3 Precise speed regulation for smooth operation and protection of peripheral equipment: high-precision drive system and stepless speed regulation device realize smooth speed regulation and precise positioning of lifting and running action, reducing impact and shaking in the process of material lifting.

3.4 Strong environmental adaptability, temperature and corrosion resistance and long service life: the equipment can be directly adapted to high temperature, corrosive and other harsh environments, compared with the traditional insulated cranes to increase the service life of more than 40%, significantly reducing the cost of replacement of equipment in special environments.

3.5 Modular design, convenient global installation and maintenance: the whole machine adopts modular assembly structure, the main beam, end beam, double trolley can be independently disassembled and assembled, on-site installation does not require complex procedures, and is suitable for different specifications of industrial plants around the world.

4. Product global adaptability and core application scenarios

4.1 Core application scenarios: This strong current environment double trolley insulated crane is widely used in all kinds of strong current, high temperature and corrosive operation scenarios around the world, and it can undertake the lifting, loading and unloading, and shifting of high-voltage equipments, smelting raw materials, corrosive materials, and precision chemical equipments, and so on.

4.2 Global standards and grid adaptation: the products comply with the international IEC, EU EN, American ANSI and other global mainstream industrial standards, according to customer demand to assist for CE, UL, GOST and other international certificates, can be directly exported to Europe, North America, Southeast Asia, the Middle East, Australia and other parts of the world.

4.3 Adaptation to global environment: high temperature spraying, anti-corrosion and anti-rust treatment of the whole machine, and temperature and corrosion-resistant design of the insulating parts can adapt to different harsh environments around the world.

4.4 Operation and Installation Adaptation: Equipped with multi-language operation interface, it can be adapted to the usage habits of operators in different regions of the world; the modularized assembly design allows the equipment to be adapted to different specifications of industrial plants around the world, and the installation process does not require large-scale special equipment, but can be completed by manual labor with conventional lifting tools, which reduces the cost of overseas on-site installation.
