Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces JB/T 9229.1-1999 “Scissors elevating platforms - Types
and basic parameters”, JB/T 9229.2-1999 “Scissors elevating platforms -
Specifications” and JB/T 9229.3-1999 “Scissors elevating platforms - Testing
method”. Compared with JB/T 9229.1-1999, the main technical changes are as
follows.
- Deleted the concept of elevating truck [Clause 2d) in JB/T 9229.1-1999];
- Modified terms and definitions as part references of GB 25849 (Clause 3 of
this edition; Appendix A of JB/T 9229.1~9229.2-1999);
- Modified height parameter series of the maximum platform from 19 grades
(0.8m~18m) to 23 grades (1m~36m) (4.2 of this edition; 3.2 of JB/T
9229.1-1999);
- Deleted model preparation (Clause 4 of JB/T 9229.1-1999);
- Deleted structure form of elevating power transfer used by steel wire rope
and/or chain, screw nut (3.3.4 and 3.8.2 of JB/T 9229.2-1999);
- Modified stability requirements and test methods so as to comply with the
provisions in GB 25849 (5.4 and 6.7 of this edition; 3.6 of JB/T 9229.2-
1999 and Clause 13, Clause 19 of JB/T 9229.3-1999);
- Modified elevating speed which is not greater than 0.4 m/s (5.3.3 of this
edition; 3.2.1 of JB/T 9229.2-1999);
- Added rotating speed which shall not be greater than 0.7 m/s (5.3.3 of this
edition);
- Added walking speed at which it can walk under elevating state (5.3.3 of
this edition);
- Modified carrying capacity from elevating 100 times at 1.25 times the rated
load to elevating 30 times at 1.33 times the rated load (5.3.5 of this edition;
3.4.1 of JB/T 9229.2-1999);
- Modified descending volume from not greater than 10 mm in 20 min to 5
mm (5.3.8 of this edition; 3.8.8 of JB/T 9229.2-1999);
- Added emission requirements for internal combustion engine driven system
(5.3.10 of this edition);
- Modified guardrail height of work platform from 0.9 m to 1.1 m (5.5.4 of this
edition; 3.7.1 of JB/T 9229.2-1999);
- Added pollution requirements for hydraulic oil solid particles (5.9.6 of this
edition);
- Added “Overload protection, level indicator, emergency stop and other
safety devices shall be set” (5.11 of this edition);
- Modified reliability requirements be represented by mean time between
failures and reliability (5.12 of this edition; 3.5 of JB/T 9229.2-1999);
- Added operation and use requirements (Clause 9 of this edition).
This Standard was proposed by China Machinery Industry Federation.
This Part shall be under the jurisdiction of Machinery Industry Standardization
Technical Committee on Logistics and Warehousing Equipment (CMIF/TC10)
and National Standardization Technical Committee on Elevating Platform
(SAC/TC335).
