Introduction
Excavator is a kind of engineering machinery used for earthmoving, lifting and lifting operations. Generally, it consists of a walking device, an operating device, a work device and a robot. With the development of society and the advancement of technology, the excavator is playing an increasingly important role in the construction of various engineering projects.
The excavator is a combination machine tool, which is composed of a walking device, an operating device, and a working device. The walking device includes a track frame and a hydraulic system, and the operating device includes a cab, a control placement and a control system. The working device includes a shovel and a shovel arm, and the robot is composed of a hydraulic cylinder, a hydraulic motor and other parts. Due to the many components and design considerations of excavators, the research and development of this kind of engineering machinery is constantly advancing. In order to ensure the safety and performance of the excavator, the relevant national standards for the equipment should also be continuously updated and improved.
New standards for excavators
The 2015 Chinese version of the excavator standards is developed by the China National Machinery Industry Standardization Technical Committee. This new standard can apply to all excavators of the product in the Chinese market. It includes, among others, terminology and main technical data of wheel excavators, crawler excavators, bucket strength, lifting capacity, climbing ability, dynamic performance, bucket digging force, bucket loading force and bucket digging force.
These new standards will effectively improve the performance of the products of excavators and benefit Chinas construction industry. For example, this standard specifies the testing requirements of various performance index parameters, which can effectively regulate and guide the design process of excavators, and reduce manufacturing cost and improve the safety of machinery and products.
In addition to the newly developed standard for the excavator, in recent years, some relevant national departments have also implemented testing and certification of the excavator to minimize operating risks and improve product performance. In 2015, the State Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) implemented a quality inspection program for excavators to test their noise, air pollution and other environmental indicators. The establishment of a solid testing and certification system for excavators has greatly improved the safety and reliability of the product.
Conclusion
The excavator is a kind of engineering machinery used for earthmoving, lifting and lifting operations. With the advancement of society and the advancement of technology, the research and development of excavators are constantly advancing to ensure the safety and performance of the excavator. With the introduction of the new standard and certification requirements, excavator performance has been significantly improved. It is expected that in the future, the innovation and development of excavator technology will continue, and the inspection and certification standards will be further improved in order to achieve its safe and efficient operation.
