Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents" Drafting is required. This document replaces GB/T 27697-2011 "Vertical Hydraulic Jacks". Compared with GB/T 27697-2011, in addition to structural adjustments and In addition to editorial changes, the main technical changes are as follows. The definition of vertical hydraulic jack has been changed (see 3.1, 2.1 of the.2011 edition); - The definition of rated lifting capacity has been changed (see 3.2, 2.2 of the.2011 edition); - Added the definition of piston rod pressing force (see 3.7); - Added the definition of work system (see 3.8); - The type has been changed (see 4.1, 3.1 of the.2011 edition); - Added illustrations of typical types of jacks with other power sources (see 4.1); - The visual inspection requirements and test methods for jacks have been changed, that is, the content of jack hydraulic system sealing has been added (see 5.1, 6.1, 4.15, 4.16, 5.1 of the.2011 edition); Added requirements and test methods for jack control switches of other power sources (see 5.3, 6.3); - The requirements and test methods for the maximum pressing force of the piston rod have been changed (see 5.7, 6.7, 4.6, 5.7 of the.2011 edition); - Added the requirements, test methods and inspection items for oil return valve test (see 5.8, 6.8 and Table 3); - The requirements and test methods for static load tests have been changed (see 5.12, 6.12, 4.5, 5.6 of the.2011 edition); - The requirements and test methods for dynamic load tests have been changed (see 5.13, 6.13, 4.10, 5.11 of the.2011 edition); - The requirements and test methods of the tilt loading test were changed, and "tilt loading test" was changed to "stability test" (see 5.14, 6.14, 4.11, 5.12 of the.2011 edition); Added electrical safety requirements for electric jacks (see 5.18); - The requirements for other power sources have been changed, and the requirements and test methods for electric jacks powered by car cigarette lighters have been added (see 5.19, 6.18, 4.17 of the.2011 edition); The test method for safety valves has been changed (see 6.5, 5.4 of the.2011 edition); - The test method for limit check has been changed, and hydraulic limit and mechanical limit are no longer listed separately (see 6.6, 5.5.1,.2011 edition). 5.5.2); The handle operating force test method has been changed to avoid the operating force test requirement that only applies to the no-load lifting oil pump (see 6.10,.2011 Version 5.9); The inspection items in the inspection item table have been changed (see Table 3, Table 3 of the.2011 edition); - The marking content has been changed, including adding the description of basic parameters and potential risks of the jack (see 8.1, 7.1 of the.2011 edition); - Changed the packaging contents, including adding the requirement that the electric jack must include an electrical schematic diagram in the instruction manual (see 8.2.3,.2011 version 7.2).
