STK was founded in the 1980s as a maintenance company for construction machinery. Over the years we have grown and developed into the all-round tower crane specialist that we are today, specialises in the rental of tower cranes in different tonnage class. Besides rental, we are also active in sales of tower cranes. Our strength is "all under own management" and with our own transport and 3 mobile cranes and our specialist construction team, we assemble and dismantle our fleet of approx. 135 tower cranes, which we also service entirely with our own mechanics. We are an SCC Petrochemistry-certified company operating world wide. We have expert knowledge of all notable brands of tower cranes and have been the official dealer of Terex Comedil for the Dutch market since 2003.
