What is a girder in a crane?

图片
A girder is the main support beam in a crane A girder in a crane refers to the primary structural beam that carries loads and supports movement. It forms the backbone of overhead lifting systems. This beam bears the weight of hoists, trolleys, and the lifted object as it travels along the runway. Key roles of the main beam A girder: Supports hoist and trolley movement Transfers loads to end trucks Maintains balance across span In industrial overhead cranes, the design of the girder directly affects load capacity, travel smoothness, and reliability. YG Crane builds single and double girder systems for various heavy lifting needs.  Girder design determines crane strength The shape and structure of a girder define how much load it can carry. A strong beam resists bending and deformation. In heavy duty systems, engineers use robust steel sections or box structures to increase strength. Structural aspects that matter Girder strength depends on: Beam cross‑section Material grade Fabricat...

How Does a Rail Mounted Gantry Crane Work?

What is a Rail Mounted Gantry Crane ? A rail mounted gantry crane (RMG) is a type of crane that runs on tracks, typically in container yards, warehouses, or ports. This crane moves along the rails and uses a trolley to lift and move heavy loads. Core Components of a Rail Mounted Gantry Crane The primary components of a rail crane include: The Gantry: The main structure that holds the crane’s hoist and trolley. It spans the entire width of the working area. The Rails: The track system on which the crane moves. Rails provide a stable pathway for the gantry. The Hoist and Trolley: The hoist lifts the load, while the trolley moves the hoist horizontally across the gantry. Control System: The system that manages the crane’s movement, load lifting, and safety operations. How Does the Rail Mounted Gantry Crane Operate? Movement and Control Mechanism The rail mounted gantry crane operates along tracks laid on the ground, and its movement is facilitated by a set of wheels attached to the ...

How do port cranes work​?

  What Are Port Cranes ? Port cranes are large lifting devices used in shipping areas. They help load and unload cargo from ships. These machines move containers between ships and storage areas. Their design allows smooth vertical and horizontal movement. Each crane stands tall on fixed or movable platforms. Some run on tracks. Others stay in one place. They all have strong arms and wires to lift heavy loads. Operators control them from cabins or remote systems. These cranes work day and night to keep ports running. Key Components of Port Cranes Every port crane has basic parts. These include the boom, trolley, hoist, and base. The boom is the long arm. It extends to reach cargo. The trolley moves along the boom. It carries the hoist. The hoist does the lifting. It uses cables and motors to raise and lower goods. Modern cranes also have sensors. These detect weight and position. This improves safety. Cranes also have control systems. Operators use joysticks or touchscreens to ...
