The purpose of this standard is to facilitate the preparation of the user to communicate with the manufacturer about the physical aspects of health and safety regulations on the use of products and Consultation. When the present class C defined in the standard terms and Class A or Class B difference in terms, for a class C in accordance with the present design and manufacturing standards of Equipment, its provisions take precedence over other standard items. This criterion is satisfied EU Machinery Directive 98/37/EC (Amended 98/79/EC Directive from) basic requirements. Conveying concrete and mortar, injection, casting machine Safety requirements1 ScopeThis standard specifies the transport of concrete and mortar, injection, casting machine and safety requirements to eliminate or reduce the risk of major technology Surgical measures. This standard relates to the delivery, and great danger injection machine fabrics that may occur when the manufacturer using conditions designed Harmful, dangerous conditions and events (see Chapter 4). This standard safety requirements for concrete and mortar conveyor, jet, cloth and its components. Device may be stationary or mobile. This standard applies mechanical described in 3.3 to 3.7. This standard does not include. --- moved in the transport, and the cloth during operation of the injection apparatus; --- this standard equipment suitable for operating chamber; --- noise (significant harm); ---vibration; --- EMC standard is not specified in this column. And a delivery vehicle chassis, and fabric work injection engine driven not by the main power system on the device, not in this standard Column. As a special case, this device does not include the same standard in combination with a mixer truck (see 3.3). Existing special predetermined operation (such as explosive gas, electromagnetic compatibility, voltage, frequency and capacity different from the utility power supply network, Or due to electronic components, earthquakes, lightning, in road use, danger in the production, transportation, commissioning process, the non-wireless radio control The remote generation of the relevant circumstances, the compressor and the pressure vessel, etc.), this standard is not otherwise required.2 Normative referencesTerms of the following documents become provisions of this standard by reference in this standard.
