Advantages of single girder gantry crane
Simple & reasonable crane structure, easy crane installation & operation
Good usability and high performance at a low cost
Low and simple crane maintenance
Parts of gantry cranes can be standardized, generalized, or serialized.
Features of single girder gantry crane
The main beam, support legs, ground beam, and crane traveling mechanism are the main part of a single girder gantry crane.
There are two types of main beams and support legs: box type and truss type. Box type is good for techniques and easy fabrication, while truss type is light in dead weight and strong in wind resistance. The complete machine has a low dead weight, a simple structure, and is simple to install and maintain.
If you intend to use it in an environment containing flammable, explosive, or corrosive gas, please notify Yuantai Crane so that we can outfit the gantry crane with appropriate safe devices to ensure your operation safety.
As for crane control, there are three control options: ground handle, wireless remote control, and cab control.

Safety feature of single girder electric hoist gantry crane
Overload protection devices are installed, which provide a loud alarm warning when overloads occur.
Limit switches are used to prevent the crane hook from being over lifted or lowered.
To ensure a long working life, a high quality polyurethane buffer is used on the hoist gantry crane.
For the sake of your operator's safety, room control and remote control are available.
In the event of an unstable voltage supply, low voltage protection is used.
When an emergency occurs, an emergency stop button is installed to stop the equipment.
Current overload protection system, as well as others, and so on.
Application of single girder gantry crane
A single girder gantry crane is a type of general use gantry crane that is commonly used in open ground, warehouses, ports, the granite industry, the cement pipe industry, open yards, container depots, and shipyards, among other places.

As for the material handling in hazardous application, it is is strictly prohibited. For example, the electric hoist single girder gantry rane is not allowed to handle melt metal, flammable, or explosive objects, etc.

Single girder gantry crane comparison: Box type v.s. Truss type
Box type single girder gantry cranes and truss type single girder gantry cranes are the two types of single girder gantry cranes. What are the distinctions between the various types of single girder overhead cranes? Generally,

Box type single girder gantry crane

The box type single girder gantry crane is a medium-sized crane that travels in track and is usually equipped with a standard CD MD electric hoist as the lifting mechanism, with the electric hoist traversing along the lower flange of the main girder, which is made of high-quality steel plates.

Truss Type Single Girder Gantry Crane

A truss type single girder gantry crane is constructed of truss girder, made of steel bars, with lighter dead weight and higher wind resistant ability, compared with that of box type gantry crane.
