GB/T 13332-2008Earth-moving machinery -- Hydraulic excavators and backhoe loaders -- Methods of determining tool forces (English PDF)

Foreword

This standard is identical with ISO 6015:2006 "moving machinery - Hydraulic excavators and backhoe loaders determination Digging Force" (English Chinese Version).

This standard is equivalent translation ISO 6015:2006.

For ease of use, this standard made the following editorial changes.

--- "This International Standard" be replaced by "this standard";

--- Deleted international standards foreword;

--- To ISO 6015:2006 international standard referenced with the international standard has been adopted as the standard instead of the corresponding country.

This standard replaces GB/T 13332-1991 "Hydraulic excavators Test Method." this standard compared with GB/T 13332-1991, the main changes are as follows.

--- Standard name from "Hydraulic excavators Test Method" to "earth-moving machinery - Hydraulic excavators and backhoe loaders dig Determination of "digging force;

--- Standard English name was modified accordingly;

--- Increasing the standard preface;

--- According to Chapter 4, "determination" of the contents of the provisions have been rearranged;

--- Increased Chapter 5, "Calculation Method" and Chapter 6, "Verifying rated digging force and closing force." the standard proposed by China Machinery Industry Federation.

This standard by the national earthmoving machinery Standardization Technical Committee (SAC/TC334) centralized.

This standard was drafted. Tianjin Institute of Mechanical Engineering, Xuzhou Excavator Manufacture Co., Ltd., Xiamen, Xiamen Engineering Machinery Co., Ltd.

3 Terms and Definitions

The following terms and definitions apply to this standard.

Alone operation or the bucket cylinder arm cylinder, bucket or cutting edge at the leading edge, not in force at the tip of the bucket teeth produced.

In the arm cylinder is placed in force with respect to the arm pin has a rotational torque, the front edge of the bucket produced.

Note. When using the backhoe bucket to move the leading edge to the host direction.

when the bucket posture is horizontal and parallel to the ground plane and the ground plane is located in the leading edge of the bucket when the front edge of the bucket arm solution Pressure cylinder action arising under the arm cylinder horizontal digging force.

Bucket digging force of the bucket cylinder in which a pin having a relative rotational torque when the bucket leading edge generated.

Note. When using the backhoe bucket to move the leading edge to the host direction; when using shovel means, away from the front edge of the bucket host direction.
