OZUZR

Universal Lock-type Rapid Connecting Links
(fast assembly and disassembly)
acc. to DIN 22258-1, PN-G-46705, MT/T 99
and FASING Technical Requirements

Application

For connecting round link chains (in vertical and horizontal position), mining flat link chains (in horizontal position only) and other chains upon agreement with FASING. OZUZR connecting links undergo qualification testing in 100%. The tests consist of test force application to the links in the value of ~75% to ~85% of breaking force.

For all types of connecting links there are appropriate strength grades:
PN-acc. to PN-G-46705, DIN-acc. to DIN 22258-1 and PW, D, D-MAX acc. to FASING Technical Requirements, DIN 22258-1 and PN-G-46705
