Description:
YZS type adopts main and auxiliary double trolleys, four-beam and four-track structures, mainly composed of bridge frame, main trolley, auxiliary trolley, hook beam, crane operation and electrical parts. The main trolley runs on the main beam track outside the bridge frame, and the auxiliary trolley is on the bridge frame. The inner side auxiliary beam runs on the track. The main trolley pick-up device is a hook beam with a fixed spacing for lifting and transporting ladle. The sub-trolley runs under the main trolley, and the pick-up device is a hook to cooperate with the main hook. To dump molten steel, steel slag, and other auxiliary lifting operations.
The YZ type cast bridge crane adopts a double beam single trolley structure, which is mainly composed of bridge frame, trolley, hook beam, trolley operation and electrical parts. The main hook and fetch device is a hook beam with a fixed spacing, which is used to lift the ladle. , The auxiliary hook is used to cooperate with the main hook to dump molten steel, steel slag and other auxiliary lifting operations.
The operating mechanism of the cart and the main electrical equipment are installed in the main beam, and the air cooler is installed in the electrical room of the main beam. In order to reduce the thermal radiation of the molten steel to the metal structural parts, a heat insulation board is arranged along the span direction at the bottom of the main beam.
The cart running mechanism adopts a four-corner drive.
The crane is equipped with a special electronic scale, and there are obvious display devices in the driver’s room and on the bridge frame.
Mechanical Parts
1.Four welding box girder, beam deflection with DIN/FEM standard
2.Steel Material: Chinese standard Q235B and Q345B
3.Trolley rail is made of high strength hot rolled flat steel (16 Mn)
4.Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster
5.The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine
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 Wireless anti-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
Installation Service
Henan MIne Crane CO., LTD crane could supply not only overhead crane but also the overhead crane solutions, firstly, we will supply overhead bridge crane design, overhead crane manual, overhead crane drawing, overhead crane wiring diagram, overhead crane electrical diagram and overhead crane safety video before or after delivery, our technician will do supervision the installation according to the document, of course, the customer can do installation by themselves according to their requirement.
After installation, our technician will indicate to do the load test according to the overhead crane load test procedure, then overhead crane operator training and overhead crane maintenance training, all the procedure will be made according to the overhead crane training videos and overhead crane training PowerPoint,
Henan MIne Crane CO., LTD crane has a lot of honor for overhead crane certification for different overhead crane types.
