Product Structure

Comprehensive Insight into the Structure of a Single Girder Gantry Crane

The structure of a single girder gantry crane is a robust and highly efficient system meticulously engineered for tackling lighter to medium-duty lifting operations with utmost precision. By delving into its fundamental components, such as the main girder, legs, hoist, and end trucks, operators can significantly enhance the crane's performance, ensure seamless operations, and extend its service longevity. A thorough understanding of the crane's architecture empowers users to operate with heightened confidence, drastically reduce maintenance requirements, and substantially boost overall safety and productivity.

Gantry Structure (Main Beams and Legs)

The gantry structure forms the backbone of the crane, delivering the essential strength and stability needed to lift and transport heavy containers with ease. The primary components of this gantry structure include:

Main Beams (Girders): These horizontal beams span the entire width of the crane, adeptly supporting the weight of the trolley, hoisting system, and the container being elevated. These main beams are expertly designed to bear substantial loads, often crafted from high-strength steel to ensure durability and reliability.

Legs (Columns): The legs provide steadfast support to the main beams and establish a connection to the ground or rail system. For a rail-mounted gantry container crane, these legs operate on tracks along the length of the crane's working area. Conversely, for a rubber-tired gantry container crane, the legs are outfitted with robust rubber tires, granting mobility within the container yard.

Trolley and Hoisting Mechanism

The trolley is a dynamic platform that traverses along the length of the main beams. It encases the hoisting mechanism, which is pivotal for lifting and lowering containers. This mechanism comprises a sophisticated system of ropes, pulleys, and a motor-driven hoist drum that facilitates the lifting operation with precision.

Hoist Drum and Ropes: The hoist drum meticulously winds and unwinds the high-tensile steel ropes that are affixed to the spreader, regulating the vertical movement of the container. These resilient ropes are engineered to safeguard the safety and longevity of the hoisting system.

Trolley Motor: The trolley is powered by high-performance motors that enable its horizontal movement along the crane's main beams, positioning the hoist directly above the container being lifted or placed with unmatched accuracy.

End Truck

Situated at each terminus of the crane, the end trucks grant the gantry crane the capability to traverse along rails utilizing a series of wheels that glide effortlessly on the tracks. Depending on the crane's load capacity, each end truck can be equipped with 2, 4, or 8 wheels, ensuring optimal stability and superior performance.

 

Hook

Our cranes are equipped with a versatile array of lifting tools meticulously designed to accommodate diverse applications.

The hook is expertly crafted for general lifting tasks, offering a secure and reliable connection for lifting and relocating loads with unparalleled safety.

The grab bucket is brilliantly suited for handling bulk materials, facilitating efficient and secure lifting of loose or granular items with ease and precision.

Additionally, we offer a diverse range of other specialized lifting tools tailored to meet specific operational demands, ensuring maximum efficiency and safety for all your lifting operations.

Controls

Control boxes are typically mounted on the crane or hoist, and the pendant or remote console empowers the operator to seamlessly run the crane. The controls adeptly operate the drive and hoist motors and can manage Variable Frequency Drives (VFDs) to precisely control hoist speed for meticulous load positioning.

Power Supply System

Efficiently power your crane systems with our state-of-the-art solutions, including insulated conductor bars, festoon systems featuring flat cables, or cable reels, ensuring seamless energy delivery to your crane.
