The type of chain is choosen according to following conditions

Max diameter of borings (D)
D = Diameter cable d + 0.1d
Checking of self-supporting length (C/2) according to the load (see table).
If self supporting lengths depend of the load required is greater than the table limits, the chain will be supported with rollers.

 

STAYS

Steel frame stays. 

Economical solution. Thanks to their removable dividers it is very easy to add or change any cable or hose.
