GB/T 33936-2017Mine hoists—Assessment specification for recycle (English PDF)

Foreword

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

1 Scope

This standard specifies the general principle of the recovery and reconstruction of the mine hoist, the technical requirements for the assessment of the recovery and transformation, the test method of the modified product and testing regulations.

This standard applies to single rope wound mine hoist and multi-rope friction mine hoist (hereinafter referred to as "hoist").

3 Recycling the overall principle of transformation

3.1 The following products are not within the scope of recycling.

a) KJ, JKA, XKT, JTK series hoists that the state has banned from using;

b) TKD-type elevator electronic control device and the use of relay structure of the principle of lifting machine electronic control device;

c) High-speed and low-speed couplings for mine hoists.

3.2 large energy consumption, low technical performance, but in line with the "coal mine safety regulations" mine hoist.

3.3 Recycling and transformation technology program should be responsible for the transformation of the manufacturers and the transformation of the user after the joint consultation to develop.

3.4 After the transformation of single rope winding hoist should be consistent with the provisions of GB/T 20961, multi-rope friction hoist should be consistent with GB/T 10599 Provisions.

3.5 Recycling of the modified product should be in the appropriate and obvious parts of the signs set, and should be marked on the signs of the date of renovation.
