Electric gantry crane is one of the most commonly used gantry lifting equipment in a large variety of fields including manufacturing, railway, highway, construction, power station, shipyard and port. The powered gantry crane is usually equipped with electric wire rope hoist or chain hoist for heavy lifting applications. It can significantly improve efficiency for your workshop as well as ensure a safe operation. With regard to different lifting needs and working environments, we supply various types of electric gantry cranes, such as single girder gantry crane, double girder gantry crane, semi gantry crane, truss gantry crane and portable gantry crane.
Which Type of Electric Gantry Crane Will Work for You?
The electric gantry crane comes in multiple configurations and sizes to suit your individual applications. We are also capable of providing customized electric gantry crane for your particular needs.
- Single girder gantry crane
AQ-MH type single girder crane is a typical light duty gantry crane , usually equipped with AQ-CD or AQ-MD electric hoist. The European type electric hoist is also available, which features light dead weight, compact structure, small wheel pressure and nice appearance. The electric single girder gantry crane can effectively lift and move heavy goods up to 16 ton. Besides, according to specific lifting requirements such as different types of materials to be handled, the motorized gantry crane can be designed into A frame crane and L-shaped gantry crane.
Single girder electric gantry crane parameters:
- Load capacity: 3-20t
- Span: 8-35m
- Lifting height: 6-18m
- Lifting speed: 0.33-8m/min
- Trolley running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3, A4
- Double girder gantry crane
AQ-MG type double girder gantry crane is built to perform heavier lifting jobs with capacity in a range of 5 ton to 200 ton. The double girder crane can also reach a larger span, greater lifting height and higher working level in contrast to single girder design. This lifting system has many advantages, such as excellent performance, high safety, wide application and strong versatility. In addition to typical A frame double girder crane, we also supply U frame gantry crane which is preferred to handle large sized objects.
Electric double girder gantry crane parameters:
- Load capacity: 5-500t
- Span: 18-35m
- Lifting height: 6-18m
- Lifting speed: 1.5-11.5m/min
- Trolley running speed: 10-40.1m/min
- Crane running speed: 16-50m/min
- Work duty: A3-A7
U type double girder gantry crane parameters:
- Load capacity: 10-50t
- Span: 18-35m
- Lifting height: 6-18m
- Lifting speed: 5.9-13.3m/min
- Trolley running speed: 31.3-40.1m/min
- Crane running speed: 40.1-44m/min
- Work duty: A5-A6
- Semi gantry crane
Semi gantry crane is a variation of gantry lifting system with one leg running on a wall-mounted runway and the other leg running on the track of ground, making it half overhead crane and half gantry crane. Therefore, the semi gantry crane can save more floor space. The crane usually falls in two configurations including single girder and double girder.
Electric semi gantry crane parameters:
- Load capacity: 3-20t
- Span: 8-30m
- Lifting height: 6-18m
- Lifting speed: 0.33-8m/min
- Trolley running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3-A4
- Truss gantry crane
Truss gantry crane is an ideal option for many outdoor working environments with strong winds or storms. The truss type gantry crane has a rather complicated manufacturing process compared with common box type gantry crane. However, truss gantry crane has some exceptional features such as light dead weight, small windward area and simple structure.
Single girder truss gantry crane parameters:
- Load capacity: 3-20t
- Span: 8-35m
- Lifting height: 6-18m
- Lifting speed: 0.33-8m/min
- Trolley running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3, A4
In addition, we supply many other types of gantry cranes, such as rubber tyred gantry crane, rail mounted gantry crane, etc. To know more, please contact our sales manager online.
Benefits of Using An Electric Gantry Crane
- The gantry crane is capable of dealing with large and heavy duty lifting jobs and requires less manual operations.
- The electric hoists can greatly promote efficiency of your gantry crane.
- The powered gantry crane is a cost-efficient alternative to overhead crane as it does not require the construction of wall-mounted runway or engineered columns.
- It has excellent safety, easy transportation and high productivity.
- It can be customized for larger lifting needs or special applications.
Design Options for Gantry Crane System
The gantry crane consists of three main mechanisms, including lifting mechanism, trolley running mechanism and crane running mechanism.
Lifting mechanism
The hoisting mechanism is one of the most fundamental and essential parts of gantry crane, used for raising and lowering heavy loads. When it comes to lifting mechanism design, several main parameters should be specified, including lifting capacity, work duty, lifting height and speed. At present, motor drive is widely adopted in many hoisting mechanisms, which provides simple operation, easy maintenance and reliable performance.
The electric hoist for gantry crane mainly comes in two types, electric chain hoist and wire rope hoist. The wire rope hoist is usually the best option for most applications as it covers a wide range of lifting needs, from a couple of tons to 50 ton, 100 ton and even beyond. When it comes to small or light duty lifting applications such as workstation and shop, the chain hoist can be a cost-effective alternative.
Running mechanism
The gantry crane is composed of two main running mechanisms, trolley running mechanism and crane running mechanism. The trolley is mainly used to support hoisting mechanism and run horizontally along gantry crane girder. The crane running mechanism is used to drive the whole equipment to move, and it can be classified into track and trackless operations. For instance, rail mounted gantry crane travels along fixed rails at the bottom, whereas rubber tyred gantry crane or wheel mounted gantry crane can move freely within working areas without need of fixed rail path. According to the specific applications, you can choose the most suitable running mechanism.
