China was the first to discover and use natural borax world countries. However, the production of boride before the founding of New China was very small, and the domestic demand for borax was mainly dependent on imports. China began to establish the boron mining and processing industry in 1956. Through several five-year plans, a complete system has been formed from boron mining to deep processing. Mining technology, mineral processing test research and comprehensive utilization have made progress. More than 30 kinds of boron fine chemical products are produced, which can basically meet the needs of relevant domestic industries. According to statistics, as of 1996, China had 62 types of boron mines, 37 borax plants and 8 boric acid plants. The production of boron ore, borax and boric acid in China in recent years is shown in the table below.
China's boron ore, borax and boric acid production in recent years
product name | 1993 | 1994 | the year 1995 | 1996 |
Boron ore (equivalent to B 2 O 3 12%) | 129.5 | 156.8 | 225.5 | 131.4 |
Borax | 20.8 | 24.2 | 25.5 | 28 |
Boric acid | 1.58 | 2.5 | 2.5 | 1.4 |

A telescoping hydraulic system is an essential component of a Tower Crane. It allows the crane to extend and retract its boom, enabling it to reach different heights and distances. This system consists of several hydraulic cylinders, valves, and hoses that work together to provide the necessary power and control.
The main hydraulic cylinder in the telescoping system is responsible for extending and retracting the boom. It is typically a double-acting cylinder, meaning it can generate force in both directions. This cylinder is connected to the base of the crane and extends vertically to support the boom.
To control the movement of the hydraulic cylinder, various valves are used. These valves regulate the flow of hydraulic fluid into and out of the cylinder, allowing for precise control of the boom's extension and retraction. The valves are typically operated by the crane operator using a control panel or joystick.
The hydraulic system also includes hoses that connect the cylinders and valves. These hoses transport the hydraulic fluid, which is typically oil, between the different components. The hoses must be durable and able to withstand high pressure to ensure the safe and efficient operation of the crane.
In addition to the main hydraulic cylinder, there may be secondary cylinders in the telescoping system that provide additional support and stability to the boom. These cylinders are typically smaller and are used to fine-tune the position and angle of the boom.
