Grua de ponte à prova de explosão QB

Double beam explosion-proof bridge crane is one lifting equipment specially for use in environments with flammable, explosive gas or dust.

The explosion-proof performance of all motors and electrical appliances of the explosion-proof hook bridge 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 bridge cranes". The explosion-proof marks are ExdIBT4 and ExdICT4 respectively.

Main beam: The main beam uses high-strength, corrosion-resistant alloy steel or other materials that meet explosion-proof standards. It can effectively avoid the explosion hazards caused by factors such as static electricity and sparks. The automatic submerged arc welding process ensures high-quality weld seams and good structural stability.

Electric Trolley: The electric lifting trolley's power conduction adopts a new device of I-beam track cable conduction, which is safe and reliable and can effectively prevent potential safety hazards.

Electrical equipment: Motors, electrical components, etc. that meet the explosion-proof requirements are used, such as flameproof motors and explosion-proof limit switches. The casings of these devices have sufficient strength and tightness, which can isolate possible sparks, arcs, etc. inside from the external explosive gases or dusts.
