Single Girder Gantry Crane Parts

Single-girder travelling gantry cranes are a vital type of lifting and transport equipment, primarily composed of two major sections: the metal structure and the mechanical transmission system. Below is an introduction to several key components of single-girder gantry cranes and it’s characteristics:

Main Components of a Single Girder Gantry Crane

• Main Girder: A box-type or truss-type beam serving as the crane’s primary load-bearing structure, with electric hoists (trolleys) running on its bottom flange or top rail.
• Legs: Support structures connecting the main girder to the bottom crossbeam, available as rigid or flexible legs, designed to transfer loads from the main girder to the ground rails.
• Bottom Beam / End Carriage: Structural component connecting the legs and wheel sets, housing the trolley travel mechanism that enables crane movement along the ground rails.
• Hoisting Mechanism (Electric Hoist): Performs vertical lifting of loads, comprising a motor, reducer, drum, and brake, typically suspended or mounted on the main girder.
• Long Travel Mechanism: Consisting of a drive unit (motor, reducer) and wheel sets, it drives the crane’s horizontal reciprocating movement along the ground rails.
• Trolley Travel Mechanism: If the electric hoist is equipped with a trolley, this mechanism drives the hoist’s lateral movement along the main beam rails (usually integrated with the hoist).
• Electrical Control System: Controls and protects all motors and mechanisms, ensuring safe and precise crane operation.
• Cabin/Operation Mode: Provides wired handles, wireless remote controls, or cabs for crane operation.

Working Principle

The working principle of a Single Girder Travelling Gantry Crane is based on coordinated lifting and traveling movements driven by electric systems. The electric hoist travels along the main girder to achieve cross movement, while the hoisting mechanism lifts and lowers the load vertically through a wire rope and hook system. Simultaneously, the gantry traveling mechanism drives the crane along ground rails to enable longitudinal movement. All motions are controlled via an electrical control system, ensuring smooth operation, precise positioning, and safe handling of materials within the rated load capacity.

 

Lifting Device and Hoist Configuration Options

Hoist single girder gantry cranes are typically equipped with electric hoists as the primary lifting mechanism, which determines the crane’s performance and load capacity. The selection of lifting devices depends on the shape and characteristics of the cargo being transported.

Weihua Crane offers customized designs, flexibly combining the most suitable electric hoist and specialized lifting gear based on the customer’s rated load capacity, duty cycle, lifting speed, and material characteristics to maximize crane operational efficiency and safety.

The double-girder gantry crane consists of main girder, outriggers, trolley travel mechanism, hoist travel mechanism, hoisting mechanism, electrical system, and safety devices. It features a stable structure and strong load-bearing capacity. Characteristics of each component are as follows:

• Main Girder: Utilizes box-type or truss-type structure, offering high strength and torsional resistance;
• Outriggers: Designed with rigid or flexible legs to accommodate varying spans and site requirements;
• Gantry: Drives the entire crane along the rails with smooth operation;
• Trolley: Enables precise lateral positioning of suspended loads;
• Hoisting Mechanism: Provides core lifting power with redundant braking systems;
• Electrical System: Integrates intelligent control and variable frequency speed regulation for low energy consumption and precise operation;
• Safety Devices: Features multiple protections including limit switches, collision prevention, and overload protection for comprehensive operational safety.

 

Working Principle

The working principle of a double-girder gantry crane primarily involves coordinating the three major movements—hoist travel, trolley traverse, and lifting operation—through an electric drive system to achieve precise material handling and positioning within three-dimensional space.

Electric motors convert electrical energy into mechanical energy. Torque is transmitted through gear reducers to drive the drum, winding the wire rope to perform vertical lifting and lowering. Simultaneously, the main girder travels longitudinally along the rails while the trolley traverses horizontally on the main beam. All three components can operate independently or in coordinated sequences. Most gantry cranes employ variable frequency drives (VFDs) and PLC automation systems to achieve smooth starts/stops, variable speed control, and intelligent safety protection. This ensures efficient and stable lifting operations under diverse working conditions.

Working Principle

Hydropower shaft gantry cranes use a vertical lifting system for deep shaft construction, connecting ground handling with controlled lifting inside the shaft.

1. Rail or foundation installation: Rails or a fixed base are installed around the shaft opening to support crane operation.

2. Gantry structure setup: The gantry frame is assembled across the shaft and connected to the hoisting system.

3. Hoisting system activation: Winches and wire ropes are engaged to provide controlled vertical lifting power.

4. Load preparation and lifting: Materials or equipment are secured to lifting hooks and raised or lowered into the shaft.

5. Vertical movement in the shaft: The load is guided along a controlled vertical path inside the shaft opening.

6. Placement and unloading:The load is positioned at the required level and released for construction use.

7. Return for next cycle: The system returns to the starting position to prepare for the next lifting operation.

The process follows a repeated cycle from setup to lifting and unloading, supporting continuous vertical transport in hydropower shaft construction. Learn more about how the equipment works: How Does a Vertical Shaft Gantry Crane Work?

Selection Guide

When selecting a rubber-tired gantry crane (RTG) for intermodal transport applications, a comprehensive evaluation must be conducted based on a variety of factors.

Industry Application Requirements

Different intermodal terminals have different operational requirements, which directly affect crane selection. Ports typically require high-capacity RTGs for continuous container handling, rail terminals prioritize flexibility and efficient rail-side operations, while inland logistics centers often focus on cost-effective solutions with moderate throughput requirements.

Intermodal Operation Frequency

The intensity of container handling operations determines the required crane configuration. High-volume terminals generally require robust, heavy-duty RTGs for continuous operation, while lower-frequency facilities can benefit from more economical solutions. For applications involving frequent yard transfers, lightweight and highly mobile crane configurations offer greater operational flexibility.

Site Conditions

Yard layout, available space, and ground bearing capacity are key factors in crane selection. Large container yards typically benefit from wide-span cranes that maximize storage density, while smaller or irregular sites may require compact designs. Ground strength should also be evaluated to ensure safe and reliable operation.

Power Supply Options

The available power source affects both operating costs and equipment flexibility. Diesel-powered RTGs offer independent operation, cable reel systems provide continuous power with low operating costs, and battery-powered RTGs combine zero-emission performance with flexible mobility, making them increasingly popular for modern terminals.

Environmental and Climate Conditions

Local environmental conditions influence crane design and protection requirements. Coastal areas often require enhanced wind resistance and corrosion protection, while cold-climate regions may need low-temperature electrical and hydraulic systems. Proper environmental adaptation helps ensure equipment reliability and service life.

The final selection requires a comprehensive, weighted evaluation of all the above factors, balancing equipment performance, initial investment, operating costs, and service life.

Price Factors

RTG Crane price depends on:

• Lifting capacity: higher capacity increases structural and drive costs.
• Span: a larger span requires stronger main beam systems.
• Lifting height: higher stacking needs more complex hoisting systems.
• Customization: automation, remote control, and special spreaders increase cost.
