The first explosion-proof national standard for gas and dust is fully adopted, and the explosion-proof grade reaches exsdembib) II BT4 / DLP A21 TA, T4, which can be applied in hazardous places where the gas environment in zone 1 and zone 2 and the dust environment in zone 21 and zone 22 are separate or coexistent.

Adopting multiple explosion-proof measures, the explosion-proof treatment of the whole machine is more safe and reliable, and the operation is more comfortable and convenient.

An independent intelligent automatic control system is added to monitor and protect the motor temperature, brake temperature and insulation of the whole machine in real time, further improving the explosion-proof performance of the whole machine.

AC variable frequency drive technology is adopted, with higher efficiency and better control performance. At the same time, the contact and carbon brush are not used, and the maintenance is easier.

Rich configuration: including headlights, front and rear turn signals, brake lights, emergency power-off switches, alarm lights, air horns, reversing warning lights, charging pins, etc.

All explosion-proof lamps and lanterns adopt die-casting aluminum alloy shell, ledn light source, low heat, long life, high brightness and maintenance free.

Zone 1 is a place where explosive gas environment may occur during normal operation

During normal operation of zone 2, explosive gas environment is unlikely to occur. If it occurs, it is also an occasional place and only exists for a short time.

During normal operation of zone 21, there may be places with enough dust to form a mixture of combustible dust and air but not designated as zone 20.

Zone 22 is a place where combustible dust clouds occasionally appear and only exist for a short time under abnormal conditions, or combustible dust clouds occasionally accumulate or may exist dust layers and produce combustible dust air mixtures.
