The forged wheel is the core part of the crane operation mechanism, which is installed on the end beam of the bridge crane or the leg of the gantry crane, supporting the crane and load to travel, and the working pressure is larger and the strength is higher. Therefore, the quality requirements of crane wheels … Read more
The main types of container gantry cranes used in the port are tire cranes and rail cranes. With the increase of the use time of the tire crane and the track crane, the welds between the trolley track and the track pad, the track pad and the top cover of the girder are opened and … Read more
In the process of forging the crane wheel, there may sometimes be cracks, so if you encounter this situation, how to deal with it? Increase the hydrostatic pressure The generation of cracks is related to the stress situation and the plasticity of the material, which is a state of the material, which not only depends … Read more
When the bridge crane is running, the wheel rim and the track contact, resulting in extrusion friction, increasing the operating resistance of the mechanism, and causing serious wear of the wheel rim or track, which is the wheel gnawing rail. Wheel gnawing rail is difficult to avoid, slight gnawing rail does not affect the normal … Read more
For the automatic warehouse using the tunnel stacker, the tunnel stacker can only run in the elevated area of the tunnel, so it also needs a variety of handling equipment with it, so that the warehouse operation area, the warehouse operation area (including inspection tally, packaging, shipping and other operations) and the high-rise shelf area … Read more
The crane wheel generally refers to the casting crane, the material box charging crane, the slab handling crane, the steel coil clamp crane, the disk crane and the other bridge crane that serves the higher level of the metallurgical plant. Due to the change of steelmaking, billet casting and steel rolling process in metallurgical enterprises, … Read more
At present, with the continuous development of port logistics and economic construction, the tonnage requirements for loading, unloading and transportation equipment in ports are also increasing, which makes the port lifting machinery is also developing in the direction of large-scale, and the wheel pressure of the crane is a key and important parameter for the … Read more
Crane refers to a multi-action lifting machinery that lifts vertically and horizontally within a certain range. Also known as the crane. It belongs to material handling machinery. The work of the crane is characterized by intermittent movement, that is, the corresponding mechanism of taking material, migration, unloading and other actions in a working cycle is … Read more
Transportation and energy sectors are major carbon emitters, and their green and low-carbon development level has an important impact on the effect of energy conservation and carbon reduction. At present, with the gradual improvement of technology application scenarios and infrastructure guarantee level in the two fields, the trend of integrated development of transportation and energy … Read more
Crane safety device refers to the device that prevents the crane from being damaged in an accident. In addition to the commonly used electrical protection devices, sound signals and color lights, there are a variety of other safety devices on the crane. Overload limiter (1) The comprehensive error of the overload limiter should not be … Read more
