Li Yongwu said three new trends, one is Material Safety Data Sheet (MSDS). According to the International Organization for Standardization, each chemical must correspond to one MSDS, and each MSDS includes at least 16 aspects of product and company identification, composition and composition information, injury identification, accident rescue, physical and chemical properties, etc. content. MSDS is equal to the product ID card in the chemical trade in international trade. Without MSDS, it is not qualified to do business with foreign countries. However, China's current understanding, mastery, and application of this situation are insufficient, and actual operations are not standardized. Failure to step up the establishment of an MSDS management system will result in great passiveness. The second is the Global System for the Classification and Labelling of Chemicals (GHS). The United Nations requires all countries to start categorizing and classifying chemicals exported in accordance with GHS requirements starting in 2008. As a member of the GHS, China has included this work as a national key scientific and technological project. According to customs statistics, China's annual import and export of chemicals reached more than 3,000 species, with an amount of more than US$40 billion. Every year due to improper classification and lack of corresponding marks and other reasons, causing a lot of economic losses. The third is the EU White Paper (REACH). This system, which was originally scheduled to be implemented in 2007, has included more than 30,000 chemicals on the EU market into the three management and monitoring systems of registration, evaluation and licensing. No monitoring system or chemical products that have not been tested will be allowed in the EU market sales. Once the EU White Paper is implemented, China will face at least 730 kinds of chemicals that are subject to registration, evaluation, licensing and restrictions, and the cost of exporting to the EU will increase by more than 5%.
Li Yongwu said that the above new trends give us the following inspiration: The increasing concern of the international community over the safety, health and environmental impact of chemicals on consumers has become a major trend. Only by earnestly studying and using the rules of the game in various international trades formulated under this general trend, and actively participating in the formulation of the rules of the game, can we gain the initiative in economic globalization.
Tower Crane cabin is the control center of the crane and is attached to the slewing unit. In order to get to the tower crane cab, the operator must climb a series of ladders within the mast.
The movement of the tower crane is controlled from the operator's cabin. Within the tower crane cabin, you'll find the operator's chair with joystick controller, electronic monitoring devices, and communication systems. Many cabins come with climate control to ensure a comfortable work environment. The Operator Cabin for Tower Crane is part of the slewing assembly.
A cabin for a tower crane is a small enclosed space located at the top of the tower crane Mast Section or tower crane jib. It is where the crane operator sits and controls the crane's movements and operations. The tower crane cabin is typically made of steel or aluminum and is designed to provide a safe and comfortable working environment for the operator. It is equipped with controls, instruments, and communication systems that allow the operator to maneuver the crane, lift and lower loads, and communicate with other personnel on the construction site. The cabin is often equipped with heating and air conditioning systems to ensure the operator's comfort in various weather conditions. Safety features such as guardrails, harness attachment points, and emergency controls are also included in the cabin design to protect the operator in case of accidents or emergencies.
