Double Girdergantry Crane

Since 40 Years, Ahmedabad based Crane Company manufacturing of Double Girder Cranes, E.O.T Crane, Bridge Cranes 0.5 - 500 Ton. Double Girder Cranes are designed with adequate factor of safety in compliance with the IS-3177 norms. The structured parts of these Double Girder EOT Cranes are designed & manufactured by a team of skilled as per IS-807. We understand customer’s requirements and make sure to satisfy them by offering Single Girder Cranes or Double Girder Cranes.

Our range of EOT Cranes are widely used for heavier loads and longer span. Moreover, these Overhead Cranes have an advantage of more height as the hook can be lifted up between the girders.

Crane

Single Girder Gantry Crane is used together with CD/MD model electric hoist, traveling on the railway for general handling and lifting operations. It is consists of 4 parts, they are main beam, electric hoist, two ground beams and four legs. This machine is a regular crane widely used at open ground and warehouse to load, unload or grab materials for highway, bridges, power station and other construction workshops projects.

Parameters feature:
Lifting capacity: 3~32t
Span: 7.5-31.5m
Max. lifting height: 30m
Lifting speed: 8 or 0.8m/min
Traveling speed: 20 or 30m/min
Work duty: A3-A5
Work temperature: -20°C-+40°C
Control method: Pendant line with pressing button, remote control or cabin control

Double girder gantry crane is used together with electric trolley as lifting device traveling on the railway with high space utilization and heavy strong structures. It is mainly composed of two main beams, electric trolley, two ground beams and four legs, the power is supplied by cable or slide wire. This kind of crane is widely used in open storage, loading and unloading operations yard, railway freight station, port cargo area, where it has a high frequency or more lifting times.

Parameters feature:

Span: 18-35m
Lifting height: 10/11m
Lifting speed:7.2m/min ~ 11.4m/min
Trolley traveling speed: 34.5m/min ~ 47.1m/min
Crane traveling speed: 38.3m/min ~ 44.6m/min
Work duty: A5-A7

Control method: Remote control or cabin control

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

QE Model double trolley overhead crane is suitable to lift long materials(wood, paper tube, pipe and bar) in workshops or outdoors to store in factory and mines. The two trolley could work separately and at the same time.
QE double girder overhead crane are mainly consists of Girder frame, Crane travelling device, two lifting trolley and electrical parts. Bridge adopts box welded structure, high degree of vertical and horizontal rigidity; crane travelling mechanism adopts separate drive. 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 moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work.
It is an excellent choice where high speeds and heavy service are required. As the widely used hoisting machinery currently especially is suitable for working at warehouses and freight yard and other department it is prohibited to use the equipment in the combustible, explosive or corrosives environment.

QDY bridge foundry crane with hook is mainly used at the place where the molten metal is liftedThe working class of the complete machine is A7,and thermalprotective coating is added at the bottom of the main girderThe assembling and test of the crane conform to the document No.ZJBT[2007]375 which was issued by General Administration of Quality Supervision,Inspection and Quarantine of the PeopleS Republic of ChinaThe place where molten nonmetal material and red-hot solid metal is lifted also can refer to this document

Casting Crane is one of the main equipments in the continuous casting technology of steelmaking. It is mainly used for pouring melted iron from additive bay of converter to converter; lifting molten steel from refining bay to refining furnace or lifting molten steel from molten steel bay to ladle turret of continuous casting machine.
