High quality remote control electric double beam explosion proof overhead traveling craneProduct introduction: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 feature: 1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible2. Long and cross travel limited by means of preliminary and final limit switches or infrared anti-collision device3. Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling4. All movements can be switched off by actuating the emergency-off switch at the control station via a main contact5. High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling6. Safety hook latch used for avoiding the lifted material out off from the hook7. Audible and visual alarm device to inform the person stay near by the travelling crane8. Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism9. Protective earth conductor is fitted as standard10. Voltage lower protection system11.
