LH type Double-girder Overhead Crane with Electric Hoist is a light-duty equipment of crane.Its structure is much more reasonable,and its assembly is much more convenient,its property is much superior.Lifting capacity is 3-50t (Gn) ,and the span is 10.5-31m,and working system is A3-A5,and ambient temperature no more than 40℃ ,and working system is 25%.It has ground controlling and remote controlling,also It has open and close,the direction entrance has side and end.
This product is widely applicable in factory,warehouse ,logistics etc,but it strictly forbid to use in such dangerous operating as easily combustible,explosive,corrosive(;acid,alkali,plating,steam),electromagnetic,electric hoist,grab liquid,overloading,dust,etc.
Technical characteristic:Trinity-drive system,The electric appliance adjusts speed without contact or spark module,and fulfills converter function,including mini-speed and double-speed,which makes traveling and lifting very stead.It is equipped with such protecting devices as alarm device to over loading,obliquely hanging,second protecting equipment preventing hook clashing the top.protecting the current lacking of any phrase etc.The operating board(handle)adopts 12v safe voltage to fulfill muti-function of protection to single girder hoist.The electric controlling can be used more than 2 million times when the voltage is 380v+5~-10%.
Choosing principle:using industry,times of starting,pushing-on per hour,the practical time per day(h),It must be marked that the electric hoist has heat-efficiency,the times of starting,pushing-on are Gn/2≈20 times/h.When the temperature is 50℃and it is grim environment,the times per hour should be divided two.
