1. Product core positioning and design basis

LXB type explosion-proof electric single girder suspension crane’s core positioning is to solve the lifting and hoisting safety problems in flammable and explosive hazardous environments, for conventional lifting equipment in flammable and explosive environments are prone to sparks, static electricity triggered explosions and fires in the industry’s pain, Henan Mine Crane on the device’s electric hoist, motors, contactors, cables and other electric components to do explosion-proof sealing treatment, transmission components to do anti-static, anti-friction sparks design, fully compliant with explosion-proof safety standards. It is fully compliant with the explosion-proof safety standards, and at the same time retains the space utilization and installation advantages of suspension cranes, without the need to take up ground space, and has low structural requirements for the plant, which is suitable for all kinds of small and medium-sized overseas flammable and explosive lifting needs of the work shop.

2. Core structural design

The whole structure of the machine is designed around the core requirements of explosion-proof safety, space utilization and flexible installation, and is a modular assembly structure, with the core consisting of three key parts, and the structures work together to achieve safe and efficient lifting in flammable and explosive environments:

2.1 Suspension load-bearing structure: a single main beam of high-quality section steel is welded and molded in lightweight, suspended directly under the roof of the plant, without the need for ground rails and brackets, completely freeing up the ground operating space; the main beam interface is standardized, and the operating span can be extended through multi-track splicing to cover the entire workshop area, adapting to the different sizes of explosion-proof operation of the workshop;

2.2 Explosion-proof lifting mechanism: equipped with special explosion-proof electric hoist, as the core explosion-proof parts of the equipment, hoist motor, reducer, control box are made of explosion-proof design, high level of protection, to eliminate electrical sparks from the source, the cable is made of explosion-proof flame-retardant material, laying explosion-proof casing, to avoid friction breakage and hidden danger;

2.3 Running drive mechanism: explosion-proof running motor and lightweight drive device, seamless connection with the main beam suspension end beam, smooth running without friction and sparks, sensitive braking, suitable for low-speed, smooth lifting needs of flammable and explosive environments, and at the same time the machine is lightweight, wheel pressure is small, the roof of the plant has no special requirements on the load-bearing structure, without additional reinforcement.

3. Core Product Advantages (Suitable for Overseas Flammable and Explosive Environments, Different from Conventional Suspension Cranes)

As a flammable and explosive environment suspension crane specially designed for flammable and explosive scenes, its core advantages revolve around explosion-proof safety, space efficiency, flexible installation, and low adaptability threshold, which perfectly fits the operation and procurement pain points of overseas customers in chemical industry, oil and gas, and pharmaceuticals, etc., and is also the core highlight that distinguishes it from the conventional electric single girder suspension cranes:

3.1 Full-process explosion-proof design, adaptable to flammable and explosive hazardous environments: all electrical components are of explosion-proof design, transmission components are anti-static treatment, cables are made of explosion-proof and flame-retardant materials, without any spark generating points, fully compliant with explosion-proof operation standards, safe operation in various types of flammable and explosive gases and dust environments, and explosion and fire safety risks are avoided from the source;

3.2 Roof hanging installation, space utilization rate is full: the equipment is hung directly under the roof of the plant, no ground columns, rails and other structures, completely releasing the ground operating space, suitable for overseas chemical and pharmaceutical workshops with dense materials, the characteristics of the narrow operating area, maximizing the workshop space utilization efficiency;

3.3 Light weight and low threshold, no special requirements for plant structure: the whole machine adopts lightweight structural design, self-weight is reduced by more than 15% compared with the same specifications of conventional explosion-proof cranes, wheel pressure is small, there is no need to do additional reinforcement of plant roofs and load-bearing structures, and it can be installed in ordinary industrial plants, which significantly saves the cost of plant renovation and infrastructure;

3.4 Modular assembly, flexible and expandable installation: the main beam is a standardized modular design, can be spliced through multiple tracks, easily extend the operating span, covering the entire workshop lifting area, while the installation does not require large-scale lifting equipment, manually can complete the assembly and suspension, and can be flexibly expanded according to the needs of the workshop expansion later track, adaptability is very strong.

4. Overseas adaptability and core application scenarios of the product

4.1 Core application scenarios: This chemical workshop explosion-proof single girder suspension trolley is widely used in various kinds of flammable and explosive hazardous operation scenarios overseas, including chemical raw material workshop, oil and gas storage area, pharmaceutical intermediate production workshop, paint manufacturing workshop, flammable and explosive dust processing workshop, etc., and it can be responsible for lifting, loading and unloading, and shifting of various kinds of explosion-proof materials, production equipments, and fittings;

4.2 Overseas standards and grid adaptation: the products comply with China’s national crane industry standards and explosion-proof safety standards, the core explosion-proof accessories are compatible with the international general explosion-proof specifications, according to customer demand for overseas ATEX, IECEx and other international explosion-proof standards; power supply parameters to support the customization (220V-660V/50Hz/60Hz), can be perfectly adapted to different regions of North America, Europe, Southeast Asia, the Middle East, etc. The power supply parameters can be customized (220V-660V/50Hz/60Hz), which can be perfectly adapted to the power grid requirements of North America, Europe, Southeast Asia, the Middle East, and other different overseas regions, and completely solve the problem of power incompatibility;

4.3 Overseas environment adaptation: the surface of the whole machine is professionally treated with antirust, anticorrosion and antistatic, which can adapt to the corrosive environment of overseas chemical workshops and the high humidity environment of oil and gas warehouses, greatly enhancing the service life of the equipment and reducing the incidence of failures in the harsh overseas environments;
