Product introduction
The double-beam crane main beam by a wide variety of steel welded, the structure is very complex. There are some problems that cause main beam deformation, such as the thin structure, needs to be improved. This paper combined with the finite element model of plate and beam to solve analytical challenges. Determine the dynamic load impact factor, the finite element analysis of the double-beam crane box-type structure of main beam, on the basis of the above, and the main beam finite element computer simulation reinforcement of the four program design and to compare. The strength of the best programs 38.7% higher than the original beam and stiffness 33.9% higher than the original beam.
Product model and Application
1. QD model 5-50/10t overhead crane with hook is mainly composed of bridge, running gear of crane, trolley and electrical device,
etc. It is divided into two working classes: A5 and A6 according to the use grade and load-up condition.
2. There are three kinds of method for entering the platform of cab: from the side, from the end and from the top. The figure is the
side entrance; arrowhead Ashows the end entrance; the top entrance is at the place there is no door.
3. The figure shows that the cab is mounted at the left end.
4. Safe slide wire or angle iron can be used for electric conduction of the crane; it can be either at the opposite side of the cab (same
as the figure) or at the sameside of the cab.
5. Operation of the crane shall be finished in the cab completely.
6. Ho is the in creased height of buffer of the crane, H0¡¨¹250.
KF CRANE is a professional production of heavy overhead crane manufacturer, overhead crane was hung in workshops, warehouses and material lifting field empty for material lifting equipment. Because of its ends situated in the tall concrete pillars or metal stent, shaped like a bridge.
Plywood Case
Double beam gantry crane is a variant of gantry crane. There are double-beam gantry cranes, as well as single-beam gantry cranes. It is mainly used for loading and unloading of outdoor cargo yard, storage yard cargo and bulk cargo. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. They have been widely used in port cargo yards. Its metal structure resembles a door-shaped frame. Two feet are installed under the main beam, which can directly walk on the ground track. The main beam can have outriggers at both ends. Gantry cranes are bridge-type cranes where the bridge is supported on the ground track by the legs on both sides. It is structurally composed of a mast, a trolley operating mechanism, a crane trolley and electrical parts. Some gantry cranes have outriggers on one side, and the other side is supported by a factory or trestle, which is called a semi-gantry crane. The gantry crane consists of the upper bridge (including the main beam and the end beam), the outriggers, and the lower beam. In order to expand the working range of the crane, the main beam can extend beyond the legs to one or both sides to form a cantilever. A crane trolley with a boom can also be used to expand the crane's operating range by tilting and rotating the boom.
Crane
Description Double girder overhead crane is composed of box type bridge frame, lifting trolley, crane traveling mechanism, and electrical system. It is rely on the bridge frame along the workshop orbital direction moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work. It could be classified into several working duties, e.g. A5, A6, A7 according to the working frequency and pure working time. Double girder overhead crane allocation hook used in machining, assembly workshop, metal workshop, metallurgy and casting workshop and warehouse handling work; allocation of grab is suitable for metallurgy, cement, chemical or open fixed span in bulk material handling. Features Reasonable structure and favorable performance. Smooth starting and stopping. Safe and reliable traveling, long life. Low noise, commodious cabin with good view. High quality automatic welding and NDT inspection. Crane drive: IP54 or IP44, level F insulation. Designed according to your required.
