Tower Crane gear mainly including 19/38/99 teeth gear, bevel gear, Tower Crane Sun Gear, and so on, which are the critical
parts of the tower crane reducer. 19 teeth gear and 38 teeth gear are
connected with two motor shaft repectively, which are connected with 99
teeth gear. The speed is reduced by the transmission of gears.
A bevel gear is a type of gear that has teeth cut on a conical surface. It is commonly used in tower cranes to transmit power between the vertical and horizontal shafts.

“The printing industry not only consumes a lot of electricity, but also generates noise. It also causes harmful emissions in inks and adhesives that are used,†Yan Tingliang, deputy director of the China Institute of Printing Science, pointed out at the forum. “In the historical trend of low-carbon green, the change in the printing industry is imperative.â€
At the 20,000-square-meter exhibition, hundreds of printing machines roared and the smell of ink dispersed in the air. Lou Tingliang said that the United States had excessively controlled the package by legislation, and the United Kingdom has also stipulated the prohibition of the use of printed materials containing toxic substances. Japan, which is separated from China by sea, introduced green printing standards as early as in 2001, controlled the use of hazardous materials, and issued certification for green printing in 2006.
“China has a lot of pressure to reduce emissions, and the printing industry must also take up the task of energy-saving emission reduction and pollution control,†said Yan. "China has now included the printing industry in the ranks of pollution control targets."
He said that although some entrepreneurs believe that emission reduction and pollution control will lead to an increase in costs, all companies that have a sense of social responsibility should regard the development of green industries as their direction of development. Moreover, through the production of green and safe products is also a good way to increase corporate credibility and product reputation. In the end, companies will certainly benefit from this.
In 2009, the total output value of the printing and copying industry reached 577.4 billion, ranking third in the world. More than 3/4 of the printing industry is located in eastern China. Among them, there are more than 3,000 various types of printing companies in Fujian, employing more than 130,000 people, and the output value of the printing industry has reached more than 26 billion yuan.
In a tower crane, the bevel gear is typically used to change the direction of rotation. The vertical shaft, which is connected to the motor, rotates vertically, while the horizontal shaft, which is connected to the crane's boom, rotates horizontally.
The bevel gear consists of two gears with intersecting axes. The teeth on the gears are cut at an angle, allowing them to mesh smoothly and transmit power. The gear ratio of the bevel gear determines the speed and torque of the rotation.
The bevel gear in a tower crane is designed to withstand heavy loads and provide efficient power transmission. It is usually made of high-strength steel to ensure durability and reliability in demanding crane operations.
Overall, the bevel gear plays a crucial role in the functioning of a tower crane by enabling the transfer of power and changing the direction of rotation between the vertical and horizontal shafts.
China's environmental protection green printing industry lags far behind the United States, Britain and other countries, the development of environmentally friendly low-carbon printing technologies and related industries. Cao Hongyi, deputy director of the Printing and Distribution Department of the China Press and Publication Administration, summarized and highly praised the rapid development of China's printing industry at the exhibition forum, but also pointed out that the printing industry has a long way to go in terms of green and low carbon.
