Single Girder Gantry Crane

A gantry crane refers to a kind of lifting machine/equipment that is used for loading and unloading various capacities of materials in different industrial environments such as a factory, workstation or a stockyard. However, there’s a lot of confusion among people about the difference between this crane and the overhead crane. Overhead crane is used for lifting and transporting material in a factory, warehouse, and workshop and has single girder type and double girder type. It travels on the rail of the building or supporting structure just like a Gantry crane. However, a gantry crane has two supporting legs and can be used for indoor/outdoor lifting and transporting work. Our company has years of experience in designing and producing industrial devices, such as overhead crane, gantry crane, marine winch, construction winch, travel lift, steel structure, flat transfer cart, and a smart car parking system. A gantry crane can be divided into full, ship-to-shore, rubber tyred and portable gantry cranes among others. However, each crane is either designed as a single girder or double girder gantry crane


This is a piece of very portable and flexible lifting equipment that best suits frequent lifting works dealing with medium /light duty. The product is made of compact structure and is lightweight. You will find this equipment being used in factories, garage, assembly line and also in warehouses. In conjunction with this crane, you can have a marine winch which is mainly used on a boat, shore, port for anchoring, fixing, mooring or towing winch. as well as a construction winch which is applied for pulling or lifting material in an industrial site, factory, warehouse, or in a mine. In case you are working near a port, consider equipping your warehouse with a Travel lift for lifting the boat from the water, putting the boat into the water, transporting the boat on land, or for maintenance work.

Major components of a single girder gantry crane include:-

  • Mechanical
  • Electrical
  • Metal structure
  • Operation cabin

Types of single girder gantry cranes

(1). L Type single girder gantry crane

This has two legs that are L-Shaped and they are responsible for offering support to the complete single=beam structure. It’s considered to perform better in railway sites and outdoor freight yards. Its parameters include:-

Lifting capacity: 5t-50t> Span length: 18m-35m> Lifting height: 6m-18m> Working class: A4 or A5> Traveling speed: 39m-48m/min> Lifting speed: 5.9m-11.2m/min

(2). BMH type single girder semi-gantry craneThe crane is used to handle bulk materials and consists of two controlling forms- ground and remote system. Its features include:-

Lifting capacity: 1t-16t> Span length: 5m-20m> Lifting height: 6m-18m> Working class: A3 or A4> Traveling speed: 20m-30m/min> Lifting speed: 3m-8m/min (or) 0.3/3m-0.8/8m/min

(3). Box-type single girder gantry crane
This crane is A-Shaped which gives it more stability to support the beam. This has a motor for changing the lifting and traveling speed and also a protection/safety device for setting the height limit. Its parameters include:-

Lifting Capacity: 3-26t> Span Length: 12m-30m> Lifting Height: 6m-18m> Working Class: A3 or A4> Traveling Speed: 20m-30m/min> Lifting Speed: 3m-8m/min or 0.3/3m-0.8/8m/min

General features that prove single girder gantry crane to be safe

  • It has a switch which controls the rate at which the crane travels
  • It’s equipped with a protection device for weight overload
  • There’s a machine that limits the lifting height
  • It has a rain cover that protects the electric hoists
  • It also has a function for stopping the crane in case of an emergency
  • Additionally, there’s a device for controlling the power voltage
  • It’s designed with sounds and flashing lights that alert operators of warnings.

Construction projects require the use of high-quality building material to avoid the future risk of collapsing. That’s why we recommend the steel structure, this is a kind of light material for building factory as well as warehouses. It also makes the building process simple, fast and safe. Additionally, you can also have a flat transfer cart in your plant to help in transporting steel plate or other materials. Why should you allow your employees to suffer finding a place to park their vehicles? Technology has made
it possible for you to have the option of installing a smart car parking system that would help you save much land area and parking time.
