The speed differential device is used in bridge construction

Bridges can help us cross complex geological environments, meet the transportation needs of the economy and society, and make our lives faster. They span mountains, rivers, lakes, steep mountains, and the steel and cement of cities, becoming a part of social and economic development. The construction of bridges is a complex and massive project, requiring a large amount of manpower, material resources, and financial resources to build bridge piers, abutments, supports, and ancillary equipment. Multiple mechanical equipment must be used to complete it. The bridge construction project requires builders to work at heights, and in order to ensure the personal safety of builders, corresponding protective devices such as speed differentials need to be equipped.

For example, in the assembly and adjustment operation of segmental box girders, the builder needs to perform precise docking and welding at high altitude. The amount of work at high altitude is large, so the builder must wear a differential device. During normal operation, the builder will not feel a sense of concern. In the event of a sudden fall due to an unexpected situation, the differential device can be locked in time to prevent accidents from happening.

From this, it can be seen that in bridge construction, the differential speed device is also essential as a safety device to prevent high-altitude workers from falling.
