• Typically made from steel plate and I-beam steel, often with a compact and lightweight design[2][4][5].

End Trucks

• Mounted at each end of the bridge girder, enabling the crane to travel along the runway beams.
• Comprise wheels and a traveling mechanism (motor, reducer, and brake)[2][4].

Runway Beams

• Parallel beams that support the entire crane structure, providing a smooth surface for the end trucks to move along.
• Integrated into the building’s support structure[4][5].

Hoist

• The mechanism that lifts and lowers the load, consisting of a motor, gearbox, and drum or chain with a hook or other lifting attachment.
• Can be CD (single lifting speed) or MD (dual lifting speed) models[2][4].

Trolley

• The unit that houses the hoist and moves horizontally along the bridge girder to position the load.
• Usually underhung, meaning it runs along the underside of the girder[3][4].

Proper Rigging

• Use appropriate slings, shackles, and other rigging equipment to securely attach the load to the crane[4].

Clear Communication

• Establish clear communication protocols between the crane operator and ground personnel to coordinate movements and avoid accidents[4].

Selecting the Right Single Girder Overhead Crane

Weight Capacity

• Determine the amount of weight you will be lifting and ensure the crane is rated for that capacity[5].

Span

• Consider the span required and ensure it is within the limits of the single girder crane, typically up to 60 feet[5].

Classification

• Ensure the crane has the correct classification for your application, such as A3, A4, or A5 working class[2][5].

Top Running vs. Under Running

• Choose between top-running and under-running configurations based on your facility’s needs, such as maximizing floor space or higher weight capacity[5].

By carefully considering these factors and understanding the components, features, and limitations of single girder overhead cranes, you can make an informed decision that meets your specific material handling needs.

Single Girder Eot Crane

Single Girder Overhead Crane: A Comprehensive Guide

Introduction

Single girder overhead cranes are a common and versatile solution for light to medium-duty material handling in various industries. This guide will delve into the components, advantages, disadvantages, and safety considerations of single girder overhead cranes.

Components of a Single Girder Overhead Crane

Bridge Girder

The bridge girder is the primary horizontal beam that spans the width of the working area. It is typically made from steel, such as S355 material, and is designed to be compact and lightweight while maintaining strong bearing capacity[1][2][5].

End Trucks

End trucks are mounted at each end of the bridge girder, enabling the crane to travel along the runway beams. They are composed of wheels and a traveling mechanism, including motors, reducers, and brakes[2][5].

Runway Beams

The runway beams are the parallel beams that support the entire crane structure, providing a smooth surface for the end trucks to move along.

Hoist

The hoist is the mechanism that lifts and lowers the load. It consists of a motor, gearbox, and drum or chain with a hook or other lifting attachment. Hoists can be equipped with single or dual lifting speeds[2][5].

Trolley

The trolley houses the hoist and moves horizontally along the bridge girder to position the load. It is usually underhung, meaning it rides on the bottom flange of the main girder[3][4][5].

Advantages of Single Girder Overhead Cranes

Cost-Effectiveness

Single girder overhead cranes are less expensive than double girder cranes due to the use of less material and faster installation times. This reduces costs on freight, installation, and materials[3][4][5].

Easy Installation and Maintenance

The design of single girder cranes is straightforward, making them easier to install and maintain compared to double girder cranes. They follow international design codes and have features like low noise, soft starting and stopping, and reliable operation[1][2][5].

Space Efficiency

Single girder cranes are ideal for facilities with limited headroom. Their low headroom design allows for maximum use of vertical space, making them suitable for buildings with height restrictions[3][4][5].

Versatility

These cranes can be customized to suit various applications, with options for different lifting capacities, spans, and heights. They can be equipped with low headroom hoists or standard room hoists and have various end carriage designs[1][2][5].

Disadvantages of Single Girder Overhead Cranes

Limited Capacity and Span

Single girder cranes have a limited weight capacity, typically up to 20 tons, and lower span capabilities compared to double girder cranes. They are not suitable for heavy-duty applications or those requiring large spans[3][4].

Reduced Hook Height

The hook height is lowered because the hoist is normally located beneath the girder. This can be a limitation in certain applications where higher hook heights are necessary[3][4].

Wear on the Beam

The under-running trolley can cause the beam to wear out prematurely, which may require more frequent maintenance[3][4].

Special Features

Adding special features such as walkways, operator cabs, and service paths can be more difficult and costly with single girder cranes[3][4].

Technical Parameters

Lifting Capacity

Single girder overhead cranes typically have a lifting capacity ranging from 0.5 tons to 20 tons[2][3].

Lifting Height

The lifting height can vary but is commonly between 3 meters to 30 meters[1][2].

Span

The span of single girder cranes can range from 5 meters to 30 meters or more, depending on the specific design[1][2].

Speeds

The cross travel speed and long travel speed are usually around 20 meters per minute, with some models offering higher speeds[1][2].

Control Methods

Single girder cranes can be operated using pendant control and/or remote control[1][2].

Safety Considerations

Proper Training

Ensure that all crane operators receive comprehensive training on safe operating procedures, emergency response, and crane maintenance[5].

Regular Inspections and Maintenance

Conduct routine inspections and maintenance to identify and address any potential issues before they become safety hazards[5].

Load Capacity Adherence

Never exceed the crane’s rated load capacity to avoid structural damage or accidents[5].

Proper Rigging

Use appropriate slings, shackles, and other rigging equipment to securely attach the load to the crane[5].

Clear Communication

Establish clear communication protocols between the crane operator and ground personnel to coordinate movements and avoid accidents[5].

Use of Safety Equipment

Utilize safety equipment such as LED crane safety lights to enhance visibility and precision during crane operations[5].

Applications

Single girder overhead cranes are widely used in various industries, including:

Manufacturing

For moving raw materials, machinery, and finished products within the facility[5].

Warehousing

To load and unload goods from trucks, ships, and storage areas[5].

Construction

Lifting and transporting heavy construction materials such as steel, concrete, and pre-fabricated sections[5].

Automotive

Handling engine blocks, body panels, and other components during assembly and maintenance[5].

Shipbuilding

Lifting and moving large sections of the ship during construction and repair[5].

By understanding the components, advantages, and safety considerations of single girder overhead cranes, you can make an informed decision about whether this type of crane is suitable for your specific application.
