1953 | The night of Sunday the 1st of February, the biggest flood in history hit the Netherlands, causing more than 2000 people to die because of this disaster. After the North Sea flood of 1953, a Delta Works Commission was installed to research the causes and developed measures to prevent such disasters in the future. They revised some of the old plans and came up with the "Deltaplan". Jan Pulleman (founder of PLM) started a crane rental company for supporting the Delta Works in 1954. PLM had more than fifty (50) cranes for rent: NCK, Priestman and Ruston Bucyrus were the brands in that time.

1980 | PLM became an official Priestman servicing and retailing company in 1980. PLM imported Priestman cranes from England to the Netherlands and other foreign countries.

1990 | At the end of the eighties, Priestman ceased its crane production, and PLM started designing and constructing its first crane. After that PLM became a crane manufacturer, and is designing and building series and customer specific cranes. Because of the years of experience and knowledge, PLM became a world leading manufacturer of reliable, heavy duty cycle cranes for several industries specially designed for the required applications.
