Top Running Overhead Crane

Top running overhead crane is a common type of overhead crane and as the name implies, its end trucks travel on the top of runway beam. It is a kind of highly efficient lifting equipment which can make full use of the space under the bridge and is not obstructed by the equipment and obstructions on the ground.

The top running crane is available in two main configurations including single girder and double girder to suit multiple applications, such as loading and transferring goods in warehouse, workshop, and material yards. Compared with underhung crane, the top running overhead crane is generally adopted for lifting larger and heavier loads, and it also provides high headroom when greater headroom is required or the building has low headroom.

Different Types of Top Running Crane

As mentioned above, our top running overhead cranes are mainly designed in two configurations. We provide many different types of overhead crane with either single girder or double girder to match your wide range of applications.

Single Girder Top Running Cranes

Single girder top running overhead crane has less cost and lower lifting capacity compared with double girder design. When it comes with applications where great headroom is not highly required, the single girder overhead crane may be a good option as the hoist usually runs underneath of the bridge girder. We manufacture multiple types of top running crane including AQ-LD type, AQ-LB type and AQ-HD type, etc.

Double Girder Top Running Cranes

Double girder top running overhead crane has high lifting capacity and of course much more cost. The crane hook can reach a greater lifting height as the hoist is typically mounted on top of the bridge beam. We supply a large variety of double girder overhead crane such as AQ-QD type, AQ-QB type and AQ-QDY type.


AQ-QD model overhead crane with hook is mainly used in inside workshop, the working class can be from A3 to A7 according to the use grade and load-up condition.

There are three kinds of method for entering the platform of cab from the side, from the end and from the top.

The cab can be either fixed at the left end or at the right end.

Safe slide wire or angle iron can be uses for electric conduction of the crane, it can be either at the opposite side of the cab or at the same-side of the cab.

Considerations When Choosing a Top Running Crane

Which is the best option for your business, top running overhead crane or under running crane? Customers should consider this question carefully before making the purchase choice. Here are some considerations you should know when choosing overhead crane lifting devices.

The structural condition of your building, whether it is a new building or an existing one.
For a new building, you have greater flexibility to make the building structure suitable for the crane coverage, so don’t forget to take the configuration of over head crane into consideration in the early planning of your project. If you already have a pre-existing building with runway beam, the top running overhead crane is absolutely your best choice.

Besides, you need to see whether your building structure is strong enough to support a top running crane. If not, you may consider underhung crane instead. In addition, the layout of your building including the ceiling height and floor space also determines which crane is your best option.

Your requirement for lifting height and capacity.
Top running overhead crane is typically the best choice for large lifting capacity to lift heavy loads such as 20 ton or more as it runs on top of runway beam. If the high headroom is your first consideration, a top running crane can also be your best option.
Installation and maintenance.
The top running overhead crane has easier installation and maintenance because it does not have to be suspended from the above. The running wheels are easy to maintain and spare parts have wide availability in contrast to under running crane.

You should consider the above issues before determining the configuration of your crane. You can also contact our sales team to help you select the best solution for your application.

Tips for Overhead Crane Operator

Overhead crane safety is essential for both your business and personnel, and the crane operator plays a very important role in the crane operation. The crane accidents can be preventable if the operator strictly follows the safety rules and conducts a correct operation. For new operators, the basic advice they should take is to receive professional training before operating a crane. They should also be trained on the specific crane of the operation and rigging because each crane may have slight differences in the operation methods.

For both new and experienced operators, they should be notified of other critical tips for the overhead crane operation. One of the most important tips is never stand under a load. Operators may get injured from unstable loads or loads drop. Though it is a small possibility of a load fall, it costs too much once it happens. Besides, the operator should strictly comply with operation and safety procedures during the crane operation.

The accidents are prone to happen when operators are careless, therefore they should focus on the operation during working. Other essential issues the operator should consider include: conduct a pre-operational inspection; check the hook; inspect the limit switch before operating the crane; take a regular maintenance of the crane components.
