Tower Crane Classification

图片
Tower-Crane Classification 1. According to whether there is a traveling mechanism, it can be divided into mobile tower cranes and stationary cranes.   Mobile tower cranes can be divided into four types: rail type, tire type, automobile type and crawler type according to the different traveling devices. The tower body of the rail-mounted tower crane is fixed on the walking chassis, which can run on a special track, with good stability, can walk with load, and has high work efficiency, so it is widely used in construction and installation projects. The tire-type, truck-type and crawler-type tower cranes have no track device and are easy to move, but they cannot walk with load and have poor stability. They are rarely produced at present.   Fixed tower cranes are divided into two types: attached self-elevating type and inner climbing type according to the different installation positions. The attached self-elevating tower crane can rise with the rise of the building a...

The history of tower cranes

  Tower crane , short for "tower crane", also known as "tower crane", is a kind of lifting equipment in construction. The tower crane originated in Europe. The first original tower crane appeared in 1912-1914. In 1923, the prototype of the first modern tower crane was made. In 1930, Germany began mass production of tower cranes and used them for construction.   China produced its own tower cranes in the 1950s. In 1954, my country's first TQ2-6 tower crane was trial-produced by the then Fushun Heavy Machinery Factory, which was subsequently produced in Shanghai Construction Machinery Factory and Harbin Construction Machinery Factory. In 1984, the Machinery Bureau of the Ministry of Construction introduced four types of tower crane data and technical training, including Potain GTMR360B, TOPKITFO/23B, FO/23B, H3/36B, at a price of 3.5 million yuan. Sichuan Jianji Factory is responsible for production. Due to the reasonable introduction of objects and adequate prepa...

The prosperity of the wind power industry continues, and Zoomlion's hoisting equipment accelerates its "entry"

 When asked if the maintenance of Tower-Cranes is complicated, Cheng Kaiqun of the Beijing-Tianjin Service Station of Zoomlion Construction Hoisting Machinery Branch said easily it is not complicated.   Tower-Cranes have become an indispensable equipment for modern construction, and are widely used in roads and bridges, electric energy, commercial super high-rises, group tower operations and other fields. It is precisely because of its importance that a slight failure will make the construction party anxiously overwhelmed. The structure of one horizontal and one vertical" seems simple, and a small problem may require checking dozens of lines. But for Cheng Kaiqun, who has accumulated more than ten years of technology, "not complicated" is the answer he gave. In a peaceful tone, it is not conceited, but full of self-confidence. Looking back on the maintenance experience on tower cranes with a height of one or two hundred meters for so m...
