GB/T 33940-2017Safety of machinery—Guide for safety design and lean manufacturing (English PDF)

Foreword

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

Introduction

Lean Manufacturing Increases productivity (better and faster) by reducing waste, reducing costs, and complicating the manufacturing process.

Various programs, techniques and methods. However, the excessive pursuit of lean manufacturing, will cause misuse of lean manufacturing methods, which will give Personnel safety and lean manufacturing goals bring significant risks. Safety is lean manufacturing trying to get better, faster, more economical, and more secure A key element of the process of benefit. In the lean manufacturing concept only focus on mechanical safety, security will be integrated into the lean manufacturing, the combination of the two, Complement each other, take into account each other is the enterprise to achieve safe production, reduce production costs, improve work efficiency and production efficiency of the important way. this Standard put forward the concept of mechanical safety design and lean manufacturing simultaneously, and give practical application of the case. The mechanical safety standards are structured as follows.

- Class A standards (basic safety standards), given the basic concepts, design principles and general characteristics applicable to all machinery.

- Class B standard (general safety standard), a safety feature involving a mechanical or a wider range of safety devices.

- Class B1, specific safety features (eg safety distance, surface temperature, noise) standard;

- B2 class, safety devices (such as two-hand control device, interlock device, pressure-sensitive devices, protective devices) standard.

- Class C standards (machine safety standards) that specify a detailed safety requirement for a particular machine or group of machines.

According to GB/T 15706, this standard belongs to class B standard.

1 Scope

This standard gives a combination of safety design and lean manufacturing in mechanical equipment and production systems, reducing damage and waste, improving performance. Full and quality guide.

This standard applies to the application of safety design and lean manufacturing practice, to minimize the mechanical equipment and production systems phase Off the waste and risk.
