Foreword

GB/T 19930 "Laboratory tests and performance requirements for protective structures of excavators earthmoving machinery" is divided into two parts.

--- Part 1. Mini excavator rollover protection structure (TOPS);

Note. The current standard number and the name of the standard part of GB/T 19930-2005 "Laboratory tests earthmoving machinery mini excavator rollover protection structures and Performance requirements ", until the revised standard, the standard number to GB/T 19930.1.

--- Part 2. ROPS above 6t excavators (ROPS).

This section GB/T 19930 Part 2.

This section drafted in accordance with GB/T 1.1-2009 given rules.

Introduction

Since the hydraulic excavator began tipping their work may support a larger body, so unlike other hydraulic excavators earthmoving machinery a Like easy tipping. However, in some of the world countries in the region, the accident data show that the hydraulic excavator need ROPS. Therefore, it is necessary ROPS for hydraulic excavator for standardization.

This section GB/T 19930 for earthmoving machinery 6t above hydraulic excavator ROPS (ROPS) provides a test method. Unlike properties GB/T 17922 stipulated machinery, hydraulic excavator with a large working device which may be necessary for the impact of ROPS performance. In addition, test methods and performance requirements for hydraulic excavators ROPS and other earth-moving machinery is different.

Laboratory earthmoving machinery excavators protective structures Tests and performance requirements - Part 2. 6t more ROPS excavator (ROPS)

1 Scope

This section GB/T 19930 established under static load uniform, repeatable evaluation ROPS (ROPS) load bearing the method by performance, and provides for typical specimen performance requirements under such loads.

This section applies to more than 6t and less than 50t hydraulic excavator ROPS ISO 6165 requirements. When the machine is turning around its back Rack longitudinal axis of the roll 360 °, and less than 30 ° slope of hard clay surface without losing contact with, ROPS driver seat belt system will indeed Paul minimal squeeze protection space. ROPS roll has been used in the presence of dangerous places.

This section applies to basic or excavator for lifting objects, remove the disk or tape, clamshell bucket, grab or claw fixture subsidiary Derived excavator means ROPS.

This section does not apply to the lifting device with a driver's cab of the excavator.

Note. Due to experimental and statistical data from the acceptable reference, this section applies to the overall quality of work is expected to be less than or equal to 50000kg excavators. Do not Exclude the possibility excavator procedure described in this section applies to a greater or lesser quality, if this requirement may result in unrealistic design, not Including excavators used in mining conditions special design.
