The runway is the track system along which the crane travels. End trucks are the wheels and axles that support the bridge beam and allow it to move along the runway[4].

Installation and Mounting Options

Top Running Cranes

Mounted on top of the runway beams, which can be part of the building structure or a freestanding system.
Offers greater lifting height and easier installation and maintenance[3][5].

Under Running Cranes

Mounted below the runway beams, often used when headroom is limited.
Less common due to the reduced lifting height and more complex installation[3][5].

Work Duty and Temperature Range

Work Duty

Overhead cranes are classified into different work duty categories (A3-A7), indicating the frequency and intensity of use[1][2].

Temperature Range

Standard cranes operate within a temperature range of -20 to +40 degrees Celsius. Specialized cranes, such as those used in casting, can operate up to +60 degrees Celsius[2].

Customization and Specialized Cranes

European Single Girder Overhead Crane Guide

Introduction

European single girder overhead cranes are advanced material handling solutions that offer several advantages over traditional crane designs. These cranes are known for their lightweight, compact structure, and high efficiency, making them ideal for various industrial applications.

Key Features and Advantages

Lightweight and Compact Structure

European single girder cranes feature a unique design concept that emphasizes light weight and small size. This results in smaller wheel pressure and lower energy consumption[1][2][4].

Increased Working Space

The compact design allows these cranes to work closer to the walls and have a higher lifting height, thereby increasing the effective working space of the workshop. This is particularly beneficial as it enables the design of smaller workshops with more complete functions, leading to significant savings on initial construction and long-term maintenance costs[1][5].

High Rigidity and Performance

These cranes are designed with maximum rigidity for a minimum crane deadweight, ensuring dependable performance and easy operation. They comply with international standards such as DIN, FEM, and ISO[2][4].

Control Methods

European single girder cranes offer multiple control methods, including pendant line button control, wireless remote control, and aerial cabin control. This flexibility makes operation simple and does not require a professional crane operator[1][2].

Safety Features

Advanced safety features include overload warning, secondary class anti-clamp, sound and light alarm devices, circuit self-check protector, and flow phase lack protection. These features enhance the safety and accuracy of the transportation process[2].

Configuration and Components

Main Components

The crane is mainly composed of a box-shaped bridge, one hoist traveling mechanism, a crane traveling mechanism, and an electrical control system. The lifting mechanism typically uses a European design wire rope hoist for single beam cranes[1].

Hoist and Traveling Mechanisms

The hoist traveling mechanism and crane traveling mechanism are designed for smooth operation, often featuring inverter control for variable speed. The standard traveling speeds for the crane and trolley are customizable, ranging from 3-30m/min and 2-20m/min, respectively[1][2].

Technical Specifications

Lifting Capacity and Span

The lifting capacity of European single girder cranes can range from 1 to 20 tons, with spans typically between 7 to 30 meters. The lifting height can vary from 6 to 18 meters depending on the configuration[1][3].

Working Class and Speed

These cranes are often classified under working class A5 or M5, indicating high-duty cycles. The lifting speed can be single, double, or VVVF (Variable Voltage Variable Frequency), with options for different speed levels[1][2].

Power Supply and Tracks

The power supply is usually 3-Ph 50Hz 380V AC. The tracks used can be P24, P38, or P43, depending on the specific requirements and load capacities[1][3].

Applications and Industries

General Material Handling

European single girder overhead cranes are widely used in various industries such as machinery, metallurgy, petroleum, petrochemical, ports, railways, civil aviation, electricity, food, paper, building materials, and electronics. They are particularly useful in situations requiring precise material handling and assembly of large-scale parts[2].

Workshop and Factory Settings

These cranes are ideal for general material handling in factories, warehouses, and stockyards. However, they are not suitable for dangerous environments such as combustible or explosive settings, where explosion-proof cranes are required[2].

Customization and After-Sales Service

Customization Options

European single girder cranes can be customized based on specific technical parameters such as lifting capacity, lifting height, lifting speed, span, power supply, and control method. Additional options include the supply of rails and bus bars[1].
