Top running overhead crane, as the name implies, travels on top of runway beams that are supported by either building columns or specifically engineered columns. The top running crane is the most common type of overhead crane that serves almost all sorts of applications. Our top running crane systems fall in two main configurations, including single girder and double girder. They can be constructed into any size and capacity to suit your lifting needs.
Types of Top Running Cranes
The top running bridge crane can be designed and built in a number of different ways to meet your individual lifting requirements. Here are several typical models provided by our company for your reference.
- AQ-LD top running single girder crane
The AQ-LD type overhead bridge crane is a popular option for most of crane users. It is designed for general purposes and usually used for light duty to moderate lifting applications.
AQ-LD single girder top running overhead crane parameters:
- Load capacity: 1-25t
- Span: 7.5-31.5m
- Lifting height: 6-30m
- Lifting speed: 0.3-8m/min
- Hoist running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3, A4
- AQ-QD double girder top running bridge crane
For heavier lifting needs, we offer double girder overhead crane with hook. This machine is perfect for frequent and heavy duty services, widely used in machine shops, warehouses, storage yards, steel mills and installation lines. The top running overhead crane is capable of lifting over 450 tons weight.
AQ-QD double girder top running overhead crane parameters:
- Load capacity: 5-450t
- Span: 10.5-31.5m
- Lifting height: 6-24m
- Lifting speed: 2.1-11.5m/min
- Trolley running speed: 27-40m/min
- Crane running speed: 42-75m/min
- Work duty: A3-A7
- AQ-LH electric hoist double girder overhead crane
AQ-LH hoist double girder overhead crane parameters:
- Load capacity: 5-50t
- Span: 10.5-31.5 m
- Lifting height: 6-30m
- Lifting speed: 0.18-8m/min
- Trolley running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3, A4
- European standard overhead crane
Utilizing the latest technology and design concept, the European standard overhead crane has a number of unique features, such as compact structure, light dead weight, delicate appearance, long working life and great efficiency. However, the downside of this crane is that it costs more than a conventional overhead crane under the same top running crane specification.
AQ-HD European type overhead crane parameters:
- Load capacity: 1-20t
- Span: 7.5-28.5m
- Lifting height: 6-18m
- Lifting speed: 0.8/5m/min
- Hoist running speed: 2-20m/min
- Crane running speed: 3-30m/min
- Work duty: A5
AQ-NLH European hoist double girder crane parameters:
- Load capacity: 5-80t
- Span: 10.5-31.5m
- Lifting height: 6-18m
- Lifting speed: 0.4-5m/min
- Trolley running speed: 2-20m/min
- Crane running speed: 3-30m/min
- Work duty: A5
AQ-QDX European standard overhead crane parameters:
- Load capacity: 5-320t
- Span: 10.5-31.5 m
- Lifting height: 6-24m
- Lifting speed: 0.2-10.7m/min
- Trolley running speed: 2.4-33m/min
- Crane running speed: 4.2-68m/min
- Work duty: A3-A5
Our top running overhead bridge crane can also be specifically designed to suit hash working environments, such as explosive and high heat. To obtain a crane that works well to your goals, contact us now and discuss your requirements with our experts.
Advantages of Top Running Overhead Crane
- The top running overhead crane provides greater lifting height than an underhung crane since it is mounted on top of runway beams.
- It is a better choice for large capacity lifting applications as it can lift up to 450 tons. This crane can also accommodate a wider span.
- The top running system has easy installation and maintenance which is also less time-consuming than a suspension crane.
- The top running overhead crane parts are with great versatility and wide availability.
- Our overhead cranes are made of durable materials so that they provide long working life and stable performance.
Wide Applications of Top Running Bridge Crane
The single and double girder top running overhead cranes can be adapted to almost all kinds of applications. They are designed for the utmost productivity and safety inside your facility. Typically, the single beam top running crane is suitable for light duty applications, such as light manufacturing and machine shops, warehousing, light assembly lines and repair shops. Whereas the double girder overhead crane is commonly found in heavy duty industries, such as steel mills, foundries, large machine shops and paper mills.
Each of our top running overhead cranes is tailored to your requirements. With our excellent technical team, we will design a proper solution for your business needs no matter what your application is.
