LV show exhibitor sued

Atlanta-based stone-crushing machine maker Hartl Crushtek LLC sued to stop Erin Systems Inc. from allegedly passing off a Hartl machine as an Erin machine at ConExpo-Con/Agg 2002, a construction and building materials trade show that began Monday in Las Vegas.

Hartl, in a lawsuit filed in U.S. District Court Tuesday, said it owns the "Hartl" and "Hartl Crushtek" marks and that its Portland, Maine-based rival tried to disguise a Hartl machine by scratching off the Hartl mark from its serial plate, partially painting the yellow-colored machine green and relabelling the machine with the "Erin" and "Powercrusher" names.

Erin Systems could not be reached for comment on the allegations.
