Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces the provisions of GB/T 17772-1999 "Laboratory Identification of Flexural Limits for Earth-moving Machinery Protection Structures". This standard Compared with GB/T 17772-1999, the main technical changes except editorial changes are as follows. --- Added some reference standards (see Chapter 2); --- Increased classification of flexural limit (DLV) (see Chapter 3); --- Increased the size and use of the deflection limit (DLV) (see Chapter 4). This standard uses the translation method equivalent to the ISO 3164.2013 "laboratory mechanical protection structure of the laboratory to determine the deflection limit Regulations. The documents of our country that have a consistent correspondence with the international documents referenced in this standard are as follows. ---GB/T 8591-2000 earth-moving machinery driver seat calibration point (ISO 5353.1995, eqv) ---GB/T 8498-2017 Basic type identification, terminology and definition of earthmoving machinery (ISO 6165.2012, IDT) This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Earthmoving Machinery Standardization Technical Committee (SAC/TC334). This standard was drafted. Tianjin Engineering Machinery Research Institute Co., Ltd. The main drafters of this standard. Jia Xiaowen, Deng Yanfang. The previous versions of the standards replaced by this standard are. ---GB/T 17772-1999. Laboratory identification of earthmoving machinery protection structure Provision for deflection limit

1 Scope

This standard specifies the laboratory-defined deflection limit (DLV) for earth-moving machinery protection structures as defined in ISO 6165. The driver of the earthmoving machinery provides protection.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Flexibility limit deflection-limitingvolume; DLV Approximate value of the tall body driver's sitting posture as defined in GB/T 8420. 3.1.1 Right angle deflection limit orthogonalDLV The flex limit in 3.1 refers to the driver's vertical projection approximation. Note. See Figure 1. 3.1.2 Fillet deflection limit roundedDLV The vertical deflection limit in 3.1.1 is rounded at the corners of the curvature close to the driver (eg, head, shoulders). Note. See Figure 2. 3.1.3 Right angle top plane orthogonaltopheadplane A rectangular horizontal plane of 270 mm by 330 mm is used to fold into a 3.1.1 vertical deflection pole in a 3.1.2 circular deflection limit. Limited top level. Note 1. See Figure 3. Note 2. The top plane is used for the drop protection structure test of the circular deflection limit. 3.2 Seat calibration point seatindexpoint; SIP The point on the vertical plane of the seat center specified in ISO 5353.
