Safety system
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 infraredanti-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
12.Wind speed indicator
13.Typhoon anchor deviceand more (contact with us more details)
