Understanding Double Girder Overhead Crane DWG

A double girder overhead crane DWG (Drawing) is a detailed and technical representation of a double girder overhead crane. These drawings are essential in the design, construction, and operation phases of crane manufacturing and use. They provide comprehensive insights into the crane’s structure, components, and assembly, enabling engineers, architects, and construction professionals to visualize and implement the crane’s design accurately.

What is a Double Girder Overhead Crane?

A double girder overhead crane consists of two parallel girders that support the crane’s trolley and hoist mechanism. These cranes are known for their robustness, high load capacity, and stability, making them ideal for heavy-duty lifting tasks. Typically, double girder overhead cranes are used in various industries such as manufacturing, construction, shipping, and warehousing.

The primary components of a double girder overhead crane include:

Girders: Two horizontal beams that provide support and stability.

Trolley: A movable unit that runs along the girders and houses the hoist.

Hoist: The lifting mechanism that raises and lowers loads.

End Trucks: Units attached to the ends of the girders, allowing the crane to travel along the runway beams.

Runway Beams: Tracks on which the crane moves horizontally across the workspace.

Control System: The interface and devices used to operate the crane, including remote controls, buttons, and safety mechanisms.
