Explosion proof Overhead Bridge Crane
* Lifting weight: 5 to 50/10 ton (in general, 5 to 10T overhead crane does not have an auxiliary hook, if you want, please advise)
* Span: 10.5 to 31.5m
* Lifting height: according to your requirements
* Working duty: A3, A5, A6, A7
* Working temperature: -25 to +40°C
* Power source: 380V, 50Hz, 3ph or other under customer's requirement
* Control Methods: usually ground control with button controller, but also can control from driver's cabin
* Working in explosive gas environment
Explosion proof Overhead Bridge Crane Structure
* Double welding box girder, beam deflection with DIN/FEM standard
* Steel material: Chinese standard Q235B and Q345B
* Trolley rail is made of high strength hot rolled flat steel (16 Mn)
* Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster
* The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine
* Hoist lifting, trolley and crane movements are controlled separately. They can run and lifting simultaneously or independently
* Heavy duty trolley lifting mechanism can reach M8 working grade
Explosion proof Overhead Bridge Crane Feature
1. Explosion proof performances of all motor, and electric components of explosion proof crane satisfy standards stipulated by GH 3836.2-2000
2. Flame-proof type "D", and the performance of the crane satisfies demands in used in JB/T5897-1991
3. The crane has obtained explosion-proof certificate after passing examinations by units designated by the government to test explosion-proof products
4. The explosion-proof marks are Ex d II BT4, Ex d II CT4, the Explosion proof Overhead Bridge Crane is suitable for areas where the explosion-transmission is not higher than IIB or IIC and the ignition temperature group of inflammable gas or explosive mixture of steam and gas is not lower than T4
