Gantry cranes are one of the most versatile and commonly used types of cranes in a variety of industries. These heavy-duty machines are capable of lifting and moving objects of all shapes and sizes, making them essential equipment for cargo and material handling, construction, and manufacturing. In this guide, we will cover everything you need to know about gantry cranes, including their types, applications, and safety measures.
Qu'est-ce qu'une grue portique ?
Gantry cranes refer to any type of crane that operates on a gantry, which is a platform that is supported by vertical legs and horizontal beams. The crane moves along the gantry on a rail system or wheels, allowing it to move objects around without the need for permanent installation. The gantry crane comes in various types and sizes to fit specific lifting needs in many industries.
Types de grues à portique
There are several types of gantry cranes available in the market today, each designed to meet specific lifting requirements. Here are some of the most common types of gantry cranes:
Fixed Gantry Cranes – These cranes have a fixed height and width, making them less flexible than other gantry crane types. Fixed gantry cranes are ideal for industrial bulk handling and transporting large containers.
Adjustable Gantry Cranes – Adjustable gantry cranes feature telescoping legs, which allow the height of the crane to be adjusted to fit different work environments. They have a higher degree of flexibility than fixed gantries, and they are ideal for use in areas where floor space is limited.
Single Girder Cranes – Single girder gantry cranes are ideal for indoor or outdoor handling of materials. They are ideal for industrial manufacturing and construction, and they are less expensive to maintain than other gantry crane types.
Double Girder Cranes – Double girder gantry cranes are similar to single girder cranes but feature two beams instead of one, making them more rigid and capable of lifting more massive objects. They are ideal for the heavy-duty lifting required in shipping docks, construction sites, and manufacturing plants.
Ponts roulants – Bridge cranes are used in facilities where high-speed, heavy lifting, and precision movement is necessary. They move along an elevated runway and feature a trolley that can be moved up and down.
Portiques portables – Portable gantries are ideal for one person usage or small industrial applications. Their lightweight feature makes them easy to transport to different work sites, and they are easy to adjust to fit specific work requirements.
Applications des grues à portique
Gantry cranes are integral equipment in several industries. They are used for lifting and moving a wide range of materials in factories, shipyards, construction sites, and more. Here are some of the most common applications of gantry cranes:
Loading and Unloading Containers – Gantry cranes are frequently used in shipping and logistics facilities for loading and unloading cargo containers from trucks and ships.
Moving Heavy Equipment – Gantry cranes allow construction companies to move heavy construction equipment, steel beams, building materials, and more around job sites.
Fabrication and Manufacturing – Gantry cranes are used in metal fabrication and manufacturing industries to lift large metal sheets or steel beams being used in railway tracks, bridges, and more.
Aircraft Maintenance – Gantry cranes are used in aircraft hangars to lift and move airplanes and parts for maintenance and repairs.
While gantry cranes are incredibly useful machines, they can also be dangerous if not handled properly. It is essential to follow specific safety measures to ensure that the crane is operated safely. Some basic safety rules that should be followed include:
Proper training is needed for all operators to prevent accidents and injuries.
Workplace assessments should be conducted before deploying the gantry crane.
The gantry crane should only be used for its intended purposes.
The crane should be thoroughly inspected before each use.
The gantry crane should be adequately maintained to ensure that it is in optimal working condition.
Gantry cranes are essential machines in several industries, and they come in several types to ensure that they can be used to meet specific lifting requirements. To ensure that they are operated safely, operators must follow specific safety measures, including undergoing proper training and adequately maintaining the machine. Gantry cranes are versatile machines that can be used for a wide range of applications, from lifting cargo containers in shipping facilities to moving heavy equipment around construction sites. Understanding the different types of gantry cranes and their applications is essential for anyone looking to purchase or operate one in the future.
