The tower crane is a fixed Crane and has to be mounted On-Site. The Tower Crane presents itself like a vertical metallic structure having a horizontal boom that can turn over an angle up to 360°. From his particular set up, the tower crane is ideal for all king of a high building or high structure construction.
Tower crane includes hammerhead tower crane, Flat Top Tower Crane, luffing type tower crane. Derrick Crane is installed on a stationary foundation.
Tower crane is a common form in urban construction sites. This kind of crane is anchored on the ground, provides an optimum blend of height and lifting capability, which is usually used for building multi-storey city building. Two horizontal jibs jut from center tower, one used lift heavy objects, another is equipped with concrete blocks as a counter weight. Tower cranes are controlled by a driver who either sits in a small cabin at the top of the tower or operates the crane from the ground using a remote control system.

A tower crane is an inverted L-shaped structure that is capable of lifting several tons of weight to precarious heights.
The most striking feature of this crane is that it is self-building and can allow a building to be constructed adjacent to or even around it.
We supply all kinds of tower crane spare parts with good quality, competitive price, short delivery and professional service.
China's LED green lighting industry continues to improve
According to statistics, as of August 7, a total of 35 companies in the energy-saving lighting concept section released the first half of the performance forecast, 31 companies pre-history. Benefiting from the continuous promotion of energy-saving policies and the maturity of the industry, 2014 was regarded as the first year of the official launch of our national LED lights, and the green lighting industry continued to improve. LEDs, that is, light-emitting diodes, have many advantages such as high luminous efficiency, fast starting speed, no pollution, and long service life compared with conventional light sources. Supporting the development of the LED industry has long been established as a national-level strategy. The government has successively formulated a number of engineering projects such as the 863 Program, Green Lighting Project, Semiconductor Lighting Project, and Ten City Wanhao Semiconductor Lighting Application Demonstration. After years of development, the industry has gradually matured, forming a complete industrial chain of LED chip preparation, LED epitaxial wafer production, LED device packaging and LED product application. In the early stage, the domestic demand for LED lights was concentrated on hotel and commercial transformation, and policy support caused the competition in the industry to a certain extent. In 2013, the newly expanded chip manufacturing equipment in the upstream market was very limited, while the price of downstream products fell by nearly 20. Overall researcher Shi Lei said that controlling investment, price adjustment and industry consolidation have caused enterprises to suffer a certain degree of pain, but it is conducive to promotion. Long-term development of the industry. At present, the price of some products on the market has been reduced to about 5 yuan per watt, with civilian conditions. According to the research of the High-tech LED Industry Research Institute, the total output value of China's lighting industry in 2013 was 263.8 billion yuan, of which the domestic market sales were slightly lower than the export value. According to China's 2012 roadmap for the phase-out of incandescent lamps, it is planned to ban the import and sale of ordinary lighting incandescent lamps of 15 watts and above on October 1, 2016. The market expansion potential brought by the stock market replacement is amazing. . Dou Linping, secretary-general of the China Lighting Society, predicts that in the next three to five years, the industry's output value is expected to exceed one trillion yuan. Judging from the 2014 semi-annual report, the peak season is first transmitted to the upstream chip manufacturing and downstream sales leaders. Taking the LED chip manufacturing company Sanan Optoelectronics as an example, the revenue in the first half of the year was 2.177 billion yuan, a year-on-year increase of 30.03. The sales revenue of LED-related products was about 2.028 billion yuan, up 40.68 year-on-year. At the same time, the company's mass production brought cost. The continuous decline has led to an accelerated increase in the gross profit margin of the chip business, reaching around 39. In the future, the company intends to continue to expand production equipment, accelerate market mergers and acquisitions, and scale benefits will be further highlighted. Liu Yifeng, an analyst with Ping An Securities Electronics Industry, said. Of course, some companies may go out early and it is difficult to enjoy this bonus. Dou Linping believes that in the industrial chain of LED lights, the mid-stream packaging enterprises belong to the processing of incoming materials, and the entry threshold is relatively low. At present, nearly 2,000 enterprises have overcapacity, and may be shuffled in advance.
