Progressive Crane, a Mazzella Company continues a tradition of family, teamwork and customer loyalty. We partner with our customers and suppliers to deliver on time and on budget. The ability to address standard and special applications, including problem installations, has established Progressive Crane as a respected leader in the industry. Progressive Crane opened its doors more than 40 years ago Progressive Electrical Systems, Inc. It was started as a service organization focusing on crane repair and services. Equipment manufacturers, at the time, neglected this facet of the business, as it was cost prohibitive for manufacturers to bring service personnel to the installed customer base.
