Double girder Anti-explosion Overhead Crane
QB Explosion proof double girder girder electric overhead traveling crane, the lifting unit is a hook, It is usually to be used to explosive environment. It mainly consists of lifting trolley,bridge frame,long traveling unit,hook and wire rope,magnet system, cabin and electric control system,etc.
The explosion proof function has special design on crane wheel,hook and wirerope to avoid spark happening,.
It has reasonable structure,light dead weight,low noise,easy operation and maintenance,low maintenance frequency and cost,superior performance,long service life.
QB Explosion proof double girder girder electric overhead traveling crane Normal capacity are 5t,10t,16t,16/3.2t,20/5t,32/5t,50/10t the span is 10.5m-31.5m or more, lifting height 16-20m or more, working class is A3~A4.
Control model: cabin control, remote control and pendant control.
Safety Features at a glance:
1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible
2. Long and cross travel limited by means of preliminary and final limit switches or infrared anti-collision device
3. Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling
4. All movements can be switched off by actuating the emergency-off switch at the control station via a main contact
5. High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling
6. Safety hook latch used for avoiding the lifted material out off from the hook
7. Audible and visual alarm device to inform the person stay near by the travelling crane
8. Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism
9. Protective earth conductor is fitted as standard
10. Voltage lower protection system
11. Current overload protection system and more (contact with us more details)
