Trolleys from Omni Metalcraft are the first and most basic component to consider when planning an Overhead Conveyor System. Omni Metalcraft Corp. offers four basic sizes of trolleys--2", 3", 4" and 6". Offered as "standard" is the vertical hole pattern, with one bolt above and one below the chain (which holds the chain firmly in place.) Trolleys are also available in these sizes with a horizontal hole pattern, with two bolts above the chain which provide a means of adding or removing trolley assemblies under conditions where the chain cannot be slackened.
