Daily maintenance and maintenance of Tower-Cranes

图片
  Daily inspection and maintenance of machinery and equipment 1. Always keep each mechanism clean, and clean all parts of dust in time; always check whether each mechanism is running normally and whether there is any noise. If a fault is found, it must be eliminated in time. 2. Check the lubrication of the gearbox, external gears and other parts. Oil and smear according to the requirements in the table. When changing the oil, remove the iron filings and impurities in the box. When refueling, pay attention to the cleanliness and filling degree of the oil. 3. Check whether the vent plugs of each reducer can be freely exhausted, and if they are blocked, they should be cleared in time; 4. Check the performance of each brake, if it is not sensitive and reliable, it should be adjusted in time; 5. Check the bolts at each connection. If they are loose or fall off, they should be tightened and supplemented in time; the connection bolts of the tower body should be checke...

Tower Crane Classification

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"

 Recently, there has been a "strong wind" in the wind power sector , the sector index has soared for a time, and the market's optimistic voices have gradually increased. The agency predicts that the installed capacity of wind power will increase significantly in the second half of the year, and the industry boom is expected to continue.   As an important end of the wind power industry chain, "wind power rush installation" makes it difficult to find large-tonnage hoisting equipment. Recently, Zoomlion's thousand-ton crawler cranes were delivered to Xinjiang customers in batches. Just after the equipment was delivered, the customer signed a product purchase agreement of 452 million yuan. The popularity of the wind power hoisting market can be seen.   Recently, there has been a "strong wind" in the wind power sector, the sector index has soared for a time, and the market's optimistic voices have gradually increased. The agency predicts that the in...

Tower Crane Driver: Watching the house being built, I can endure no matter how hot it is!

 We are the watchers of the city, watching the high-rise buildings being built, it is worth it no matter how hot it is.    The height of the building is the skyline of the city. Where is the highest point of the building? It is the tower crane operating room, that is, the height of the boom.   When everyone shouted "This life is given by the air conditioner", most of the tower crane drivers were suffering in the "tin box". They are at a height of tens of meters or even hundreds of meters above the ground. On the ground, we can rarely see what their operating room is like, and how they reach that height. Iron on the head under the scorching sun!   Tower-cranes are the most commonly used lifting equipment on construction sites, also known as tower cranes, which are the main force for vertical transportation on construction sites. At 5 o'clock the day before yesterday, Zhu Huizhong had already arrived at the construction site. "Now we are working t...

One Horizontal, One Vertical, One Tower-Crane The wind and rain travel thousands of miles!

 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...

Weihua's 500-ton super-large metallurgical crane rolled off the assembly line!

   Recently, the main structure of Weihua's 500-ton super-large metallurgical crane was successfully rolled off the production line, which once again refreshed the manufacturing record of Weihua's metallurgical crane and further consolidated Weihua's leading position in the manufacturing strength of super-large metallurgical cranes.    The crane will serve the metallurgical workshop of Tangshan Ganglu Iron and Steel Co., Ltd., with a tonnage of 500/90/15t, a span of 20.7 meters, and a working level of A8. It is the first 500-ton four-beam six-track metallurgical crane product in the province completely independently developed by Weihua Co., Ltd. .   The super-large 500-ton metallurgical crane off the production line this time carries out the whole process process control from pretreatment, blanking, welding, finishing, assembly, and testing. The overall annealing treatment and overall assembly of the reducer has verified that Weihua Co., Ltd. has a...
