- Scope
- This document specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of backhoe loaders. This document applies to self-propelled tire-type backhoe loaders (hereinafter referred to as backhoe loaders) defined in GB/T8498. Crawler-type backhoe loaders may be used as a reference.
- Introduction
Core changes in the standard revision
Technical elements 2010 version 2021 version Explanation of changes Definition of terms Includes 4 items such as maximum lifting height Simplified to 2 core terms Focus on the key parameters of rated working load and breakout force Hydraulic contamination control Unclassified provisions Added Table 1 classification requirements Gear pump/plunger pump/vane pump systems require level 19/18/17 respectively Safety alarm Basic requirements Strengthen visual + auditory dual alarm (5.3.6-5.3.7) New mandatory alarms for outrigger position, driver's seat direction, etc. Detailed explanation of key technical requirements
Hydraulic system specifications
Standard 5.2.4 specifies the upper limits of particle pollution levels for three types of hydraulic systems, among which the plunger pump system has the most stringent requirements (≤level 18/15). Implementation recommendations:
- Adopt ISO 4406 online monitoring technology
- Test oil cleanliness every 50 working hours
- Shorten filter element replacement cycle by 20%
Reliability index
5.2.9 stipulates that mean time between failures ≥ 260h, which is 15% higher than the 2010 version. Typical compliance measures:
Lingong case: By strengthening the boom welding process (UT inspection + stress relief), the service life of key structural parts is increased to 3000 hoursInspection implementation points
Inspection type Key items Instrument requirements Judgment criteria Factory inspection Braking performance, alarm device Sound level meter, pressure gauge 100% compliance with Table 2 Class A items Type inspection Emission, stability PEMS equipment, tilt table GB 20891 Stage IV Standard Evolution Analysis
The third revision of this standard reflects three major trends:
- Security Enhancement: Five new active alarm requirements are added to align with ISO 20474
- Environmental Protection Upgrade: Emission requirements are synchronized with GB 20891 Stage IV
- Digitalization: Product Identification Code (PIN) entry is mandatory (8.1.2d)
