Introduction
Double girder gantry crane is heavy gantry crane with double girders, which is widely used for general purpose. Double girder gantry crane are heavy duty crane, used at indoors and outdoors places where overhead crane�runways are not practical. The lifting capacity of the double girder gantry crane is 5 to 500 tons. The working class of the gantry crane is A5 and A6.
Application of Double Girder Gantry Crane:
Double girder gantry crane is usually used to open warehouse or along rail for general material handling and lifting work, such as, freight yard or dock, etc.
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. Double Girder EOT Crane Specification: 1. The structural parts of the Overhead Bridge Cranes are designed and manufactured as per IS-807. 2. These types of Double Girder Overhead Travelling Cranes are used for heavier loads and longer spans. 3. These Electric Overhead Traveling Cranes are widely used in various applications like transporters, trenches, erection of bulky equipment, shifting of heavy loads, mine quarries, heavy fabrication units and others. 4. They offer the advantages of low headroom as the hook can be lifted up between the girders. 5. All components are carefully selected for 'Crane duty' applications.

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.

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: Lifting capacity: 5~500t 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 Work temperature: -20°C-+40°C 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
