FOREWO~

This Indian Standard (Part 3) (First Revision) was adopted by the Bureau of Indian Standards, after the drafi finalizedby the Mining Techniques and Equipment Sectional Committee had been approved by the Mechanical EngineeringDivision Council.

This standard was first published in 1980. The experience gained in implementation of the standard has necessitatedthis revision. Presently 50, 80, 100 and 120 kN capacity shackles only are being used and for 150 and 200 kNcapacity suspension gear, chase blocks are being used in place of shackles in mines. Accordingly, in this revision,shackles used with suspension gear of 50, 80, 100 and 120 kN safe working load only are.covered, where as in theearlier standard 10, 30 and 150 kN capacity were also covered.

The shackles and pins are used in cage suspension gear assembly to connect the various components ofsuspension gear to each other. This standard has covered the shackles and pins used to connect the cage hangers,bridle chains and equalizing plates. The shackles and pins used in conjunction with safety hooks are excludedfrom the scope of this standard since their dimensions have to conform to the dimensions of bell plate to headgear due to the passage of shackles through bell plate.

This standard is issued in eight parts. The other parts in the series are:

Part 1 General requirements

Part 2 Cappels

Part 4 Bridle chains

Part 5 Distribution plates

Part 6 Safety detaching hooks (4 plate type) 80, 100 kN capacity

-Part 7 Safety detaching hooks (4 plate type) 120,150 and 200 kN capacity

Part 8 Clivey hook suspension arrangements

For the purpose of deciding whether a particular ~equirement of this standard is complied with,, the finalvalue, observed or calculated, expressing the result of a test shall be rounded off in accordance withIS 2:1960 ‘Rules for rounding of numerical values (revised’. The number of significant places retain{:d in therounded off value should be same as that of the specified vahe in this standard.
