FOREWORD
This Indian Standard (Part 2) was adopted by the Bureau of Indian Standards, after the draft finalized by the
Mining Techniques and Equipment Sectional Committee had been approved by the Mechanical Engineering
Division Council.
Haulage clips are used for connecting asetofminetubs tothe haulage rope inamine haulage system. Different
types of clips are used with over-rope under rope endless haulage system.
Maximum loaded tubs and empty tubs atatime shallbeattached withtherope, in-suchawaythat themaximum
draw bar pull on the clip do not exceed the safeworking load.
Part 1of this standard was published in 1979.While preparing Part 1of this standard, itwas felt necessary to
issue standards covering the dimensional details of components of-various types of haulage clips. Accordingly
this standard has been published inthree partsin this revision. Other parts inthe series are:
Part 1 General requirements (firsretvision)
Part 3 Lashing chain
The composition of the Committee responsible for the formulation ofthis standard isgiven in Annex A.
For the purpose of deciding whether aparticular requirement ofthis standard is complied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
IS2:1960 ‘Rules for rounding off numerical values (revised)’. Thenumber ofsignificant places retained inthe
rounded off value should be the same asthat of the specified value inthis standard.
