CLX Electric Chain Hoist Cranes We offer a range of electric and manual hoists, adding to Konecranes’ versatility in designing cranes to customers’ specific requirements. Other options you may choose from include single or double girder construction, profile or box type girders and over- or under-running configurations to fit your. Lifting Weight tons. Span mm or other. Lifting Height 16mm or other. Introduction of double girder overhead electric lift crane. The double girder overhead electric lift crane is designed and manufactured with European standard. Its lifting capacity can be up to trolley is installed between two main girders.
is that double girder cranes typically provide better hook height because the hoist is positioned between the girders, typically providing an additional 2 to 3 feet of lift. • • Comparison to Forklifts: Less Product Damage - Forklifts often cause more damage to the product than overhead cranes. This occursFile Size: 2MB. ABUS underslung overhead travelling cranes offer load capacities of up to 8 t and spans of up to 25 m. The design versions DLVM and EDL feature rolled section girders. EDKs are designed with torsion resistant welded box girders. A comprehensive programme of accessories and components is also available for ABUS underslung overhead travelling cranes.
The problem of the design of box-type bridge girders for electric overhead traveling cranes is formulated as a minimum weight design problem with inequality constraints. The restrictions placed on the design problem include limitations on the maximum allowable deflections and stresses as well as on the shock absorbing capacity during accidental Cited by: 2.

Equipment Overhead Cranes We provide an extensive range of cranes, for light duty applications and demanding processes. Our standard offering with high quality basic equipment or advanced offering with high-tech features is usually enough; but if it isn’t, we can also provide a.
Double Girder Bridge Cranes - The crane consists of two bridge girders supported on two end trucks. The trolley runs on rails on the top of the bridge girders. Gantry Cranes - These cranes are essentially the same as the regular overhead cranes except that the bridge for carrying the trolley or trolleys is rigidly supported on two or more.

Overhead cranes cover a rectangular area, moving a load side to side and backward and forward. The lifting device, called a hoist is mounted on a trolley for horizontal movement across a bridge beam connected to one or more horizontal girders which are supported at either end by end trucks.
The end trucks are attached at right angles to the girders and move on fixed runways. Optimization of Box Type Girder of Overhead Crane from the top plate, the best optimized results (maximum deflection=mm and maximum bending stress=MPa, mass of girder=kg) are.
Overhead cranes one the most common material handling equipment available in industries. Recently, designers and analysts have shown their interest in optimization of such cranes.
This paper deals with the parametric optimization of box girder of overhead crane with different spans and fixed loading capacity. Initially, the effect of each designFile Size: KB. The single girder overhead crane is really light in weight as compared to other cranes and therefore shares the privilege of low transportation expenses as well.
The overhead crane has very low headroom making it versatile in the loads it can lift and offer more compatibility as well.
An optimal design for minimum weight bridge girders of electric overhead traveling cranes is presented. The welded box-type girder is modeled as a simply supported beam. A generalized steepest descent algorithm is adopted for mathematical programming, which includes constraints on stress, displacement, buckling, and : S.
Cho, B. Kwak. A double girder overhead crane is comprised of two girders with the hoist (crab unit) running on rails mounted on top of the girders.
Double girder overhead cranes are typically used where the operational processes demand either a greater lifting height or where more specialised processes such as load turning are required. An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments.
An overhead crane consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane (USA.
CMAA Specification #74 (single girder cranes) does not require that girders be cambered, but this option uses a different deflection limit. The majority of crane manufacturers build File Size: KB. ZLW Series ZLW Series Double Girder Bridge Cranes utilize structural girders, and are often used where capacities are over 10 tons and/or long spans are needed.
Product Advantages The advantages of double girder traveling bridge cranes become particularly evident with load capacities over 10 tons, or spans of over 50'. The Walthers Cornerstone HO Scale Heavy-Duty Overhead Crane is a great machine for detailing the interior of many heavy industrial structures.
Easily adaptable to operations in any building, this ton capacity crane is designed for maximum detail with easy construction. It includes dual trolleys with hooks and motor details, an operator's cab, decals and instructions.
It's perfect for the. ABUS ZLK double girder travelling cranes: the heavy brigade Two girders are simply stronger than one, making ABUS double girder travelling cranes the ideal solution for the area coverage handling of heavy loads up to t.
Like all ABUS factory cranes, these units are available with a number of main girder connection versions to best. DQCRANES’ DH series of Wire Rope Electric Hoist with lifting capacity ranging from t to 63t, can be categorized as fixed type, single girder suspension type and double girder travelling electric type by their different structures and as general hoist, dedicated clean room hoist, explosion-proof hoist, dedicated nuclear plant hoist and.
Overhead Traveling (EOT) Cranes. TYPES OF ELECTRIC OVERHEAD CRANES There are various types of overhead cranes with many being highly specialized, but the great majority of installations fall into one of three categories: a) Top running single girder bridge cranes, b) Top running double girder bridge cranes and c) Under-running single girder File Size: 1MB.Single girder overhead crane, as its name suggests, is a kind of crane with single girder and it is applied on many work occasions, such as factory, warehouse, machinery workshop and maintenance Group is located in crane town Henan, has decades’ experience and leading technology.
