One of the first and most basic consideration in planning an Overhead Conveyor System is to determine the correct size and type of
Trolley to be used. The total load to be
carried on each trolley, including the weight of the trolley itself, the carrier and the actual load are all key factors in
determining the “size” of the trolley, rail and chain that is
necessary for a particular application. The conditions under which the trolley will
operate, including the degree of contamination and temperatures to which it will be
subjected, are important factors in the “type” of trolley, wheel and seal that should be selected for a particular application.
Trolleys are the first and most basic component to consider when planning an overhead conveyor system. ACG 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.
