Вибухозахищений електричний підйомник

The explosion proof electric hoist produced by Weihua Group has passed the international ATEX/IECEx explosion proof certification and is specially designed for Zone 1/Zone 2 hazardous areas, providing absolute safe operation guarantee with zero sparks and low surface temperature. Explosion proof electric hoists are often used in hazardous areas where flammable and explosive gases/dust exist, such as petrochemical industry, natural gas mining, mining operations, and pharmaceutical workshops. Since sparks or high temperatures from ordinary electric hoists may cause catastrophic accidents, explosion proof electric hoists are required.

Core advantages of explosion proof electric hoist

Military-grade explosion proof design to eliminate potential safety hazards

• Fully enclosed explosion-proof motor: The explosion proof electric hoist adopts a cast aluminum alloy shell + copper heat dissipation structure. It has passed ATEX/IECEx international certification and is suitable for Zone 1/Zone 2 hazardous areas to ensure that the motor runs without sparks and has a low surface temperature (≤135°C).
• Dual redundant safety system: electromagnetic brake + mechanical brake double insurance, self-locking instantly when power is cut off, eliminating the risk of falling; автоматичне відключення при перевантаженні 110% to avoid accidents.
• Anti-static components: The explosion proof electric hoist is equipped with anti-static wire ropes and non-metal pulleys as standard to eliminate the hidden danger of frictional discharge and is especially suitable for dust explosion environments (such as flour mills and lithium battery workshops).

Інтелектуальне управління, precise and efficient

• Безступінчате регулювання швидкості перетворення частоти: 0.1-10m/min stepless speed adjustment, achieving millimeter-level precise positioning, especially suitable for precision equipment installation or dangerous goods transportation.
• Електричний підйомник з пультом дистанційного керування: 50-meter explosion proof remote control (Ex ia IIC T4 certification), keeping operators away from dangerous areas and reducing personal safety risks.
• Real-time status monitoring: Integrated LED display screen provides real-time feedback of load weight, висота підйому, motor temperature and fault codes, and supports Internet of Things remote monitoring (необов’язковий).

Extreme environmental adaptability and durability

• Wide temperature range operation: stable operation in -40℃ extreme cold to +60℃ high temperature environment, equipped with a low-temperature start module to ensure normal use in severely cold areas (such as Arctic oil fields).
• Super corrosion resistance: The explosion proof electric hoist shell is coated with epoxy resin (salt spray resistance 2000 години), and all stainless steel materials are optional, which can easily cope with chemical corrosive gases or marine high-humidity environments.
• Модульна конструкція: The explosion proof electric hoist is compatible with various installation methods such as I-beam, KBK track, single-girder bridge, тощо. It supports non-standard customization and adapts to the needs of complex working conditions.
