1) In order to close and open bucket (scoop) this grab bucket is easy to use         
the manufactured products with relatively small particles by using H.Y.D           
system and mechanical properties , 

    2) It's characteristics is that crane wire hook can be used in any equipments         
        regardless of 1EA or 2EA and now they are frequently used in the filed
        of harbor loading and unloading and open storage or uploading
        and  downloading goods at the place where there is
        no power source of crane. 

    3)It is favorable in safety and convenience to apply wireless
        transmitter-receiver and uses remote controller at long                           
      distance about 100 M to open and operate bucket. 

    4) Power source uses general battery DC-12 V for general                         
        automobiles so competitiveness is excellent in the field of operation.
 
    5) When to store equipments outdoors with water proof of important                 
        parts in operation, design of vibration-isolation it can prevent                     
        damage of remote control and sol check valve from short circuit which can       
        be happened owing to rain or something else or flooding. 

    6) Especially, gearing edge which can be greatly important in bucket and
        by using ware plate (Above HB400) equipped with high intensity and
        wear resistance tie rod link or fragile part that can keep balance
        grab self, up. or down is fully considered crash cushions and
        life of the equipment in poor surroundings.
