QB type double beam explosion-proof bridge crane is a type of double beam crane used in situations with explosion-proof requirements, suitable for hazardous areas of Zone 1 or Zone 2. 5 tons and 10 tons are two commonly used tonnage. When selecting QB explosion-proof bridge crane, users should indicate the technical requirements such as working system, maximum and minimum temperature of working environment, and type of power supply. The editor will introduce the technical parameters of a 5-ton and 10 ton double beam explosion-proof bridge crane.
