What Are Double Girder Overhead Cranes Used For?

Double girder bridge cranes are used in a variety of industrial and commercial settings for lifting and moving heavy loads. With the different below-the-hook lifting devices, the double girder overhead crane can be used in different workplaces or specific work processes. Here are some common uses of double girder overhead cranes:


Double girder eot cranes are an essential tool in manufacturing, particularly in heavy industry, where large and heavy materials need to be moved around a facility. Typical applications of overhead cranes in manufacturing include: moving raw materials, work-in-progress, and finished products around the manufacturing floor, from one workstation to another, or from one storage area to another; lifting and positioning large or heavy components, such as engines, transmissions, or structural components, during assembly operations; moving heavy machinery and equipment, such as large motors or generators, for maintenance or repair purposes; loading and unloading trucks and shipping containers with raw materials or finished products.


Double beam eot cranes can be used in large warehouses and distribution centers to lift and move heavy loads of goods and materials. Some typical applications of overhead cranes in warehousing include: loading and unloading trucks and containers with heavy or bulky materials; moving materials around the warehouse, from one storage area to another, or from storage to processing or production areas; stacking and organizing materials in the warehouse, making it easier to locate and retrieve items when needed.

Power plants

Double girder overhead cranes can be a vital component in a power plant, particularly in the construction and maintenance of large power generation facilities. Some common applications of overhead cranes in power plants include: lifting and positioning heavy equipment, such as boilers, turbines, generators, and transformers, during the construction and installation of the power plant; moving heavy components, such as pumps and motors, during maintenance and repair operations; moving materials, such as fuel, coal, ash, and other materials, around the power plant from storage to processing or disposal areas.


In metallurgical applications, double girder top running overhead cranes are used for different processes in the steel mill: casting, feeding, forging, storage, etc. According to different processes, there are different types of double girder cranes such as cranes for slab hanlding, cranes for lifting molten iron, cranes for loading and storing steel products, etc.

Waste disposal

Double girder overhead crane plays a key role in facilities for garbage handling and recycling. For example, in a waste-to-energy plant where waste is burned to generate electricity, overhead cranes may be used to move waste materials from one location to another within the facility, such as from the waste storage area to the combustion chamber. In a waste sorting and recycling facility, double girder overhead bridge crane may be used to move large items of waste to sorting stations where they can be manually sorted into different categories for recycling or disposal.

Overall, double girder overhead cranes are a versatile and efficient solution for lifting and moving heavy loads in various industries and applications.

Types of Steel Structures

  • Portal steel frame structure: it is a single-storey steel structure in which the load-bearing structure adopts a solid-web steel frame of equal section or variable section, and the enclosure system adopts light roof panels and wall panels. Because of its large span, simple installation, economical cost, and wide application, portal steel frame is commonly found in single-story industrial buildings, such as warehouses, workshops, etc.
  • Multi-storey steel frame: it is widely used in multi-storey buildings such as residences, schools, office buildings, multi-storey industrial plants, theaters, shopping malls, etc. The main load-bearing structure is frame beams and columns.
  • Grid structure: it can be used as the roof of two-way buildings with large column spacing, such as hangars, stack sheds, exhibition halls, waiting halls, stadiums, grandstand awnings, gas stations, etc. The specific forms of grid steel structure are various. All rod pipes joint and form a whole through bolt balls, which is convenient for installation. The rod pipe is small and convenient for shipping.

Main Structure Of Double Girder Overhead Travelling Crane

The electric double girder overhead travelling crane is mainly composed of bridge frame (main beam, end beam, trolley running track, etc.), hoist trolley, bridge running mechanism and electrical control system.

Double Girder Overhead Crane Structure

Bridge Frame

  • Main beam: a box-shaped structure. The section of the main girder is systematically analyzed and calculated using ANSYS finite element calculation method to ensure that it has sufficient strength, rigidity and overall stability.
  • End beam: the connection between the end beam and the main beam is a rigid connection.
  • Trolley track: it adopts the whole track with joints welded together to ensure that the trolley runs well.
  • Walkway and railing: the tread of the bridge platform is made of non-slip patterned steel plate with a thickness of 3mm. Railings with a height of 1050mm are installed on the passages of the bridge frame.
  • Cabin: it adopts a closed, toughened glass driver’s cab. The framework of the driver’s cab is welded by rolled steel and stamped thin steel plates, and the floor surface is covered with insulating rubber carpets. Both the inside and outside of the glass can be wiped safely and conveniently.

Hoist Trolley

  • Hoisting mechanism: composed of driving device, steel wire rope winding system, fetching device and safety protection device.
  • Trolley running mechanism: it drives the lifting trolley. In order to improve the working efficiency of the overhead travelling crane, the speed is generally faster.

Bridge Running Mechanism

  • Two independent drive systems are used to drive the crane separately.
  • The wheel diameter and material of the bridge running mechanism are selected according to the maximum supporting force of the wheel under the most unfavorable conditions to ensure that wheels will not be overloaded.

Electrical Control System

  • The standard power supply of our double girder electric overhead cranes is three-phase AC, the rated voltage is 380V, and the rated frequency is 50Hz. It can also be designed according to user requirements.
  • Crane power feed: (1) safety cable (2) flexible cable
  • Trolley power feed: cable trolley
  • The slides used for the feeding of flexible cables and cable trolleys can be steel rope slides, I-steel slides, and special-shaped steel slides.
