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.
Product Detail
European-style Gantry Crane is the most popular & common crane which is widely used in workshop, warehouse, etc. Its outstanding advantage is DIN/FEM design, light weight design, modular design, advanced manufacturing technology, high security, high reliability, low-energy & free-maintenance and intelligentize.
European type gantry crane are mainly consists of Girder frame, Crane travelling device, hoist as the lifting device and electrical parts, it is designed with working grade of A5~A8 according to the use frequency.
Bridge adopts box welded structure, high degree of vertical and horizontal rigidity. It has a strong beam and a stable travelling mechanism; the emergency switch can stop any movement once any dangerous happened.
It is rely on the bridge frame along the workshop rail direction moves forward-backward, the hoisting mechanism can be hoist type or winch type according to the lifting capacity and working demand. The trolley along the main beam direction moves left-right and the hook lift up-down.
Features
Design and fabricate according to FEM/DIN standard
--Light duty & modular design
--Advanced fabricated technology
--High security --High reliability
--Low-energy and maintenance-free
--Intelligentialize

These hoists typically have lower capital costs when compared to drum hoists due to characteristic lighter, single-drum constructions and lower installed power requirements.
Koepe drums are subjected to high cyclic fatigue loads, typically reversed during every drum revolution.
Design is of necessity for infinite fatigue life. The head ropes of a Koepe hoist are subjected to cyclic variations in operating loads due to the required use of tail, or balancing ropes. For adequate rope life, the static load range should be limited to approximately 12 % of the rope breaking strength. Regular rope maintenance and replacement is essential on these hoists.
Koepe hoists are not normally favoured for depths of wind greater than 1800 m.However, for depths within the 1800 m range, very large payloads can be handled by increasing the number of head ropes.
Koepe hoists frequently find application as service hoists for men and materials using a cage and counterweight arrangement. These are often configured for use with push button cage control. Drum hoists, both single drum and double drum, are the most frequently used type of hoisting system. With multi-layer coiling the double drum hoist is frequently used for lengths of wind to 2500 meters, but can be used for lengths of wind greater than 3000 metres.
Although normally winding in balance, the range of brake torque required during emergency braking requires some form of brake control system to provide acceptable retardation levels under all winding conditions. The control of emergency braking retardation for single drum hoists is particularly problematic due to the high out of balance loads and great variation in the natural rates of retardation for different hoisting conditions. KF has extensive experience in the design of suitable brake control systems.
