Safety requirements
The hazard range included in this standard indicates the scope of the technical standard.
This standard specifies the safety requirements for winches. The standard is based on physical standards and emergency procedures and puts forward restrictions on mining winches. 8515·1997
This standard covers all the requirements for the safety of mining winches. It is used to measure the hazards generated at various stages of the machine life cycle as described in 13.11 of GB/T15706.1-1S95. The standard is applicable to step-up winches, winch vehicles, target mine grade and column vehicles, transport vehicles, endless rope winches, zone gate winches, pneumatic winches, TC.8 winches, 2IT-5.3 type mining operation vehicles, section 4 mining vehicles (hereinafter referred to as winches). 2 Referenced standards
The provisions contained in the following standards, which are cited in this standard, constitute the provisions of this standard. When this standard is published, the versions shown are in effect. New standards will be revised. Other producers using this standard are also considering the possibility of using the following standards to measure new versions of vehicles. GB II-SO

4.% The vertical roll joint will not reduce the mechanical performance and the defect of over-performance 4.9 The outermost layer of wire rope should be at least 2.5 times the diameter of the wire rope. 4.10 Except for the damper car and the rubber car, the car plate is equipped with an expandable working brake. 411: For the car with the same level of transportation, not only an independent working brake should be set, but also an independent safety brake. The safety brake can be driven by gravity or elastic force. 4.12 The safety belt is effective. The car has the function of manual drive and electric drive. In the case of power failure, 4.13 The core area of ​​the brake shoe (belt) and the brake wheel should not be greater than 7. 4. The brake should be matched (the belt and the brake wheel are not defective, and there is no oil speed. 4.15 The correct point (the distance between the belt and the brake is loosened): the translation block brake shall not be greater than 2m, and the upper and lower machines shall be larger than 2. The belt shall not be used in the center of the shoe.
4.16 The shoe (book) is cheap and twisted, and the surface or the end of the head or the nail head is smaller than 2mr4.17 The winch and the transportation are relatively large in number.
