Double-girder overhead cranes use a double bridge structure for greater stability. They handle loads from 5 to 800 tons and support large-span operations. These cranes serve industries like construction, mining, and heavy manufacturing. They perform complex and high-intensity lifting tasks efficiently.

سمات: double girder overhead crane can be equipped with motor grab, electromagnetic chuck and other fetching devices, to meet the needs of lifting various types of materials.

Applicable: factory, warehouse and goods yard for loading, unloading and lifting work, prohibited in flammable, explosive and corrosive gas filled environment work.

مقدمة عن أجزاء الرافعات العلوية

An overhead crane contains one or two parallel main girders, end girders, a hoisting mechanism, an electrical system, safety devices, and a trolley running mechanism. These main girders join together through cross girders, forming a stable frame structure. The hoisting mechanism attaches to a trolley, which then moves along the upper flange of the main girder and efficiently lifts large-tonnage loads.

العارضة

The girder serves as the main load-bearing structure of an overhead crane, spanning the entire facility width. It directly supports both the hoisting device and the trolley, and ultimately determines the crane’s load capacity and operational stability.

مسار

Overhead tracks run along both sides of the facility's upper structure, supporting the entire crane system. The crane's girder mechanism travels on these tracks, moving lengthwise to position the crane flexibly across the whole work area.

جهاز الرفع

The hoisting device acts as the core component of an overhead crane, performing all lifting and lowering tasks. It typically consists of a motor, wire ropes, pulleys, and a hook, enabling precise control over both the height and position of the load.

عربة

The trolley operates as a mobile mechanism on the bridge frame. It carries the hoisting device and moves laterally along the beam, thereby enabling the crane to position loads precisely across the entire bridge coverage area.

عوارض النهاية

End brackets mount at both ends of the main beam, where they support the full bridge structure and connect to the main beam running mechanism. Moreover, this design allows the crane to move smoothly along the track and reliably bear heavy loads.

Control unit

This system operates the crane through multiple options, including hook control, remote control, or cab operation
