High-end sort of the large power series
The DID HI-PWR-SHK roller chains have thicker hyperlink plates than HI-PWR-S roller chains, and therefore are the highest in tensile power and allowable load between standard application chains, hence staying suitable for low speed heavy duty transmission.
Advisable employs
?The HI-PWR-SHK roller chains are 25 percent higher in tensile strength and 50 % larger in maximum allowable load than the typical roller chains, but since their excess weight is heavier, driving efficiency declines at high velocity. So, they are suitable for hefty duty at low pace applications.

Multilevel parking machines, pipe benders, building machines, and so forth.
Choice of chains
Pick a suitable HI-PWR-SHK style chain dependant on “Low-speed selection”
HI-PWR-SHK series is available in simplex.
Sprockets
Conventional sprockets for multiplex chains can’t be utilised.
Connecting backlinks and offset links
The most beneficial attribute from the HI-PWR-SHK roller chains is substantial greatest allowable load. Consequently, interference-fitted connecting links (H connecting back links) with little power degradation are utilised.
The connecting plate and the connecting pins are connected with spring pins. The tensile strength of an H connecting link is equivalent to that in the chain, but the allowable load is somewhat decrease than that from the chain.
HI-PWR-S form roller chains do not have any offset website link. Use an even quantity of back links.
In no way make the holes of the connecting plate bigger and in no way make the pins thinner to facilitate the function for fitting the pins in to the connecting plate, considering the fact that otherwise the fatigue strength will probably be lowered.
