Birth History of Concrete Pump Truck

In 1900, the first patent on tower cranes for construction was issued. In 1923, prototypes of modern tower cranes were made. In 1930, Germany began mass production of tower cranes and used them for construction. Schwing was founded in 1934 as the earliest concrete equipment manufacturer and the originator of trailer pumps, truck-mounted pumps and pump trucks. In 1957, the world’s first split concrete pump was manufactured by Schwing and started to be put on the market. In 1965, Schwing Company once again introduced an on-board pump with trans-epochal significance, using a tall Mercedes-Benz as the chassis.

Correctly Replace for Cutting Ring and Wear Plate

Spectacle wear plate and cutting ring are a kind of vulnerable parts that are used in conjunction with concrete machinery equipment such as trailer pumps, pump trucks, and truck-mounted pumps. During the conveying process of the concrete, the cutting ring and the wear plate alternately run between the two feeding holes due to the feeding and feeding back and forth. The wear plate and the cutting ring interact with each other, which will cause frequent collisions. Therefore, it needs to be replaced frequently.

China Made the World's Longest Boom Pump Truck

With the longest boom pump truck in the world settled in China, this pumping device has a length of 101 meters, which means that this concrete pump truck can independently complete about 95% of the concrete pumping tasks in China's buildings. The use of this type of pump truck means that construction workers do not need to overturn and change the way the concrete is poured. Therefore, if the pump truck is applied to the construction of a building, it will only take three days to cooperate with the famous residential building machine in China. Just complete the construction of one floor.
