Introduction
Machinery safety standard is structured as follows.
a) A Class standard (basic safety standards) give basic concepts apply to all mechanical, design principles and general characteristics.
b) Class B standards (generic safety standards), a mechanical (or more) security features or a category concerns (or classes) to use a wide range
Safety guards.
--- B1 class, specific security features (such as safety distances, surface temperature and noise) standards;
--- B2 class, the safety device (such as a hand control devices, interlocking devices, pressure sensitive devices and guards).
c) Class C standards (machinery safety standards), to a specific detailed security requirements for a machine or group of machines.
This standard is a Class C standard GB/T 15706.1-2007 provisions.
If the provisions of the Class A or Class B standards the provisions of this type C standard is not the same, for the design and manufacture in accordance with the provisions of this type C standard
Machines, priority should be the implementation of the C class standards.

1 Scope
This section GB/T 24667 provides for self-propelled, hanging, semi-mounted and trailed agricultural machines only in the use of tools in order to play
Open power transmission guards moving parts design and safety requirements and determination methods of manufacture. This section also specifies the manufacturer shall provide security
Type Full operational information (including legacy risk).
The major part of the risks involved (listed in Appendix A), hazardous situations and hazardous events, under the manufacturing schedule and foreseeable conditions of use
Powertrain guard moving parts associated (see Chapters 4 and 5).
This section does not apply to moving parts of power transmission guards tractors, aircraft, air cushion vehicles, lawn and garden equipment.

3 Terms and Definitions
Terms and definitions established in GB 10395.1 apply to this section.
4 power transmission moving parts
4.1 pairs of power transmission hazardous moving parts should be protection by setting the location, a safe distance or fixed guards.
4.2 Design of guards should be considered in the risk of operator, the normal function of the machine, other dangerous generated (as a result of emissions, or remove residue accumulation
Risk of clogging generated) and mechanical feed device interference.
4.3 Design of protective devices should be easy to operate and maintain the machine properly.
4.4 protective device may be rigid mesh or grid. It allows network or grid size of the opening depends on the distance between the guard and the danger zone (see
GB 12265.1-1997 Table 1, Table 3, Table 4 or 6). Design guards shall ensure that network or grid during normal operation and does not use
Deformed, resulting in the opening size and distance relationship exceeds the limits specified in GB 12265.1-1997.
4.5 pairs predicted normal access (such as maintenance or adjustment time) hazardous areas should use protective equipment. Under permissive conditions, guards should be used
Always connected to the machine type (such as a hinge or bolt connection).
4.6 having to open doorways into the machine or protective device or removed after the power cut off the exposed parts of the machine continues to rotate or shipped
Moving in the region of closest approach doorways or protective devices should be provided indicating the rotation is easy to see visual signal, or direction of rotation of the auditory channel
Number, or applicable safety signs (see 6.1 and 6.2).
4.7 Under normal operating conditions need to enter the danger zone guards shall ensure that only the use of tools to open (take a conscious move
As to open), without the use of tools can be automatically locked.
Note. The "normal access" means the intended use of the machine during normal operation the operator must adjust certain parts to achieve a given function.
