GB/T 9465.1-1988Vehicle-mounted mobile elevating work platform (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 9465-2008 "High-altitude work vehicle". Compared with GB/T 9465-2008, except for editorial changes, mainly the technical changes are as follows.

--- Removed the "Basic Parameter Series for Work Vehicles" requirement (see 2008 edition 4.3);

---Modified Chapter 3 aerial work vehicle, maximum working platform height, minimum working platform height, maximum working height, maximum operation Amplitude, rated load definition, deleted the definition of aerial work platform (see 2008 edition 3.2), increased mobile lift work level Taiwan (see 3.2), minimum operating height (see 3.7) definition;

---Working environment conditions increase the relative humidity regulations of insulated working vehicles (see 5.1.9);

--- Increased the requirements for the safety performance of modified vehicles (see 5.1.3, 5.1.5);

--- Increased the limit of the "outer edge speed" of the swing speed (see 5.8.3);

--- Revised the calculation requirements for stability and structural safety (see 5.3.3, 5.3.5);

--- Increased the safety provisions of the work platform (see 5.7.6, 5.7.12, 5.7.15), aerial work vehicles greater than 30m should be equipped with anemometer (see 5.7.14), interlocking of the leg and extension structure (see 5.7.2), safety requirements for the safety of the rated load of the work vehicle (see 5.7.16~5.7.18);

--- Increased the safety performance requirements of hydraulic system actuators (see 5.4), improved the platform sinking capacity under rated load (see 5.8.5, 2008 edition 5.7.5);

--- Increased control requirements for electrical systems (see 5.5);

--- Revise the maximum working platform height error to 1% (see 5.8.6, 2008 version 5.7.6);

--- Increased 20kV, 500kV grade insulated aerial work vehicle content (see Table 3, 2008 edition table 4);

---The detection electrode is changed from "63kV or more folding arm type working vehicle" to "66kV and above working vehicle", the fixed position is "100mm~150mm" was changed to "not less than 50mm" (see 5.10.1.1, 2008 edition 5.9.1);

--- Added the requirement of "equal potential connection ring for voltage equipotential working vehicle of 110kV and above" (see 5.10.1.2);

--- Removed the insulation working platform attribute "used as primary insulation and auxiliary insulation", removed the external insulation work platform wall thickness insulation power frequency Withstand voltage test requirements, the applied voltage of preventive test and handover acceptance test is changed from "20kV" to "45kV", handover acceptance the duration of the test was changed from "5min ± 5s" to "1min ± 5s" (see 5.10.2.2, 2008 edition 5.9.2.2);

---Insulated parts type test changed from "insulation arm" to "insulation arm and accessories" (see 5.10.3, 2008 version 5.9.3);

--- The test item of the basic arm insulation arm section (auxiliary insulation) is adjusted to be part of the insulation performance test of the whole vehicle.

Edge performance test (see 6.13.1);

--- Increased the withstand voltage and leakage current test items of the components after installation of the main insulation arm (see 6.13.1.1.2, 6.13.1.2);

--- Added a test example of the withstand voltage and leakage current of the telescopic arm type insulated car (see 6.13.1, 6.13.5);

--- Added auxiliary insulation boom test requirements (see 6.13.4);

--- Increased grounding device requirements for insulated aerial work vehicles (see 5.10.3.6);

--- Revised the number of cycles for the reliability test (see 5.12, 2008 version 5.11).

This standard was proposed by the China Machinery Industry Federation.
