Product Introduction:
QB explosion proof overhead crane is a kind of lifting equipment designed for flammable and explosive gas or dust environments. Its main parts are made of explosion-proof structure and materials, which meet the strict requirements of the country and the industry for the explosion-proof level. It is widely used in the petroleum, chemical industry, natural gas, military industry, pharmaceutical industry, and other special industries that have very high requirements for safety.
The explosion-proof performance of all motors and electrical appliances of the explosion-proof hook overhead crane complies with GB3836.2-2000 “Explosion-protected electrical equipment for explosive gas atmospheres - Part 2:Flameproof enclosure 'd”. The overall performance of the crane complies with the provisions of the standard JB/T5897-2006 "Explosion-proof overhead cranes". The explosion-proof marks are ExdIBT4 and ExdICT4, respectively.
Features:
-
01
Explosion-proof design of the whole machine
Including motor, electric control system, such as brake, coupling, operating device, etc. all adopt explosion-proof treatment to meet the standard of Ex d IIB T4 and above grade.
-
02
Dust and poison prevention
Dust explosion-proof products are suitable for all kinds of combustible dust and T4 requirement areas, effectively preventing dust and harmful gases from entering the crane interior and affecting the normal operation of the equipment.
-
03
Safe and reliable
Equipped with explosion-proof limits, explosion-proof cables, explosion-proof lamps and explosion-proof operation button boxes to ensure the absolute safety of the operating environment.
-
04
Strong stability
The double main beam structure improves the carrying capacity and structural strength to meet the needs of medium and heavy lifting conditions.
-
05
Various operation modes
It can be equipped with cab, ground wired control or explosion-proof wireless remote control to adapt to different operation scenarios.
-
06
Smooth operation
Adopting low noise operation mechanism, smooth starting and braking, reducing the risk of explosion.
