Top running cranes have fixed tracks or a rail system mounted on top of each track beam, allowing the end truck to carry the bridge and crane along the top of the track system.

Top running overhead cranes run on fixed tracks mounted on the top of each track beam, which allows the end truck to carry the girder and hoist along the top. These top running cranes can be set up as single or double beams depending on the application requirements.

SEVENCRANE can provide top running overhead crane products to our customers in a short period of time, because we have our own overhead crane factory, many years of work experience and friendly cooperation with domestic logistics.

The customer trusted us very much and placed an order for 2 suits of 10-ton European-style double-girder bridge cranes and 1 set of 2-ton wall crane and accessories.

Top running crane is a lifting equipment that is placed horizontally over workshops, warehouses and yards for lifting materials. They are mounted on rails on top of the building's support structure, allowing the crane to move along the length of the building. Top running overhead crane is the most commonly used crane type which has a fixed track system installed on the top of each runway beam. The lifting capacity of top running overhead crane will not be limited and it can be manufactured to lift loads from 1 ton to 450 tons. Since the crane is supported by steel support columns or existing concrete steel building support structures, it is very suitable for moving extremely heavy loads.

(1) The comprehensive error of the overload limiter should not be greater than 5%, and the number of lifting and lifting weight can be recorded. (2) When the load reaches 90% of the rated lifting capacity, an alarm signal should be issued; when it is 100-110% of the rated lifting capacity, the power supply for the lifting control of the hanging object should be automatically cut off through interlock control.
