Member Release to reflect pulling double hoses on several Roller Boxes

Im pullinr two hoses of 80mt each on a set of roller boxes . i modelled the hose and offset it to lie on the rollers . but the rollers are being puuled as if the hoses are fixed on them . I need to reale the mebers from the rollers so that the rollers will not be pulled as if the hoses are fixed to it.
