The current mechanical instruction, 98/37/ EC, was issued on 23 July 1998 by the official gazette of the eu, replacing the 89/392/EEC issued in 1989 and the subsequent amendments to the directive 91/368/ EEC, 93/44/ EEC, 93/6/63 / EEC. Since 1 January 1995, mechanical instruction has officially become a mandatory European law, and all eu member states must incorporate some basic provisions into their respective national laws. The eu machinery directive is not aimed at technical details but focuses on mechanical design and structural safety and health provisions.
The definition of a machine in an instruction
The machinery in the mechanical instruction includes a single machine, a connected set of machines and replaceable equipment.
(1) mechanical is composed of several parts connected component, at least one component can exercise, and through the appropriate brake, control and power circuit connected, and a specific purpose, such as material processing, processing, handling, packaging, etc. Mainly includes the following products: wood processing machinery, metal cutting machine tools, forging machinery, agriculture, forestry and tractor and machine, rubber and plastic machinery, packaging machinery, lifting transportation machinery, storage equipment, construction machinery, food processing machinery, heat treatment equipment, the underground mining machinery, printing and paper making machinery, casting machinery, textile machinery, washing machinery, compressor, gas engine, pump, leather machinery, fire fighting equipment, etc.
For those machines that are packaged and transported in order to facilitate transport, they are assembled at the time of use and should be followed.
(2) the combination of machinery, for the purpose of achieving the same purpose, has been properly configured and controlled by several machines to achieve complete functions. Automatic production line... Wait.
(3) replaceable equipment are those that can change the mechanical function, removable replacement of equipment, the equipment can be put into the market sales, but by the operator will he with one or a series of different mechanical or tractor assembled together, the device is not spare parts or tools. Some equipment can be used for power or lack of power, such as the vehicle end surface mounted on the machine tool
The term "mechanical" also contains a group of machines that are arranged and controlled to achieve the integrated functions of raw materials processing, processing, handling and packaging. In addition, some safety components in use, and the components of a failure will endanger people in exposure to the safety or health of "security components", also belong to this directive contains general machinery.
Security components are authorized by the manufacturer of the established in the European common market agent sales in the market, realizing the function of security components in use, failure or malfunction of it would endanger the safety and health of personnel in the danger zone. For example, the reusable rope, the emergency stop device, the logic components that ensure the safety of the hands, the electronic sensitive devices designed for the protection personnel, the drop protection device, the overload protection device, etc.
Depending on the type of mechanical and zero components, other instructions for mechanical instruction may still be applicable. Other instructions include EMC instructions, low voltage instructions, simple pressure vessel instructions, and pressure vessel instructions.
The division of dangerous machinery
Hazardous machinery (machinery for the scope of mechanical instruction annex IV)
The 98/37/EC directive makes a significant difference between the "general mechanical" and the perceived danger (annex IV machinery). It is important to distinguish your machine from the attachment IV machine before proceeding with the instruction specification step.
