Profile
Designed、fabricated and inspected by our Wei Hua Group, the bridge-type grab ship unloader is accorded with the foreign advanced standards and latest national standards such as DIN、FEM、IEC、AWS and etc. It is suitable for unloading DIN、FEM、IEC、AWS operation for bulk ship at bulk cargo.
Materials mainly contains ore、coal and etc. The capacity of the unloading bulk is from 500t/h to 3000t/s, which has the performance of advanced technology, reliability, stability, efficiency, long service time and easy maintenance. It can meet with the requirements of Max.transportation volume, high efficiency operation. The noise and sust pollution produced during operation conform to national environment protection standard four-drum pull type grab ship unloader designed and fabricated by Weihua Group prevail in market.
In the light of the various drive mode, it can be divided into two types: trailer wagon with rope and self-propelled trolley. What’s the drive mode of the trolley is that in line with the steel wire rope that is on the drive coiling block in the machine room, it can realize traveling of the trolley. The traveling drive device of the trolley is not on the trolley, on the contrary, it is in the machine room. The lifting mechanism of the grab has two conditions, such as it is equipped on the trolley or it is not equipped on the trolley.
The bridge-type grab ship unloader that the lifting mechanism is not equipped on the trolley: generally speaking, the trolley is made up of main trolley system and auxiliary trolley system. The advantages of the bridge-type grab ship unloader includes following characteristic: such as simple structure of the trolley, light dead weight, high traveling speed, stable brake and starting. It is widely used in large and medium-sized ship unloaders. The main trolley system and auxiliary trolley system is effective for rope compensation, which can realize the horizontal movement of the grab.
The bridge-type grab ship unloader that the lifting mechanism is equipped on the trolley: it is named as semi-trail type bridge-type grab ship unloader. The drive mode of the trolley depends on the electric motor which is equipped on the trolley frame. By means of the reduction gear, it can directly drive the wheels of the trolley to realize the traveling of the trolley. Both lifting mechanism and opening-closing mechanism are equipped on the trolley. Also, it is named as load trolley.
