In 1952, the PAX fleet mainly consisted of tractors and tippers from the brands Magirus Deutz and HOGRA. The distinctive and robust HOGRA trucks were produced between 1954 and 1959. The name HOGRA is a combination of the surnames of founder A.W. van Hoek and his financier, Mrs. Gravelaar.

This model, often referred to as the Rundhauber, was recognizable by its elegant, rounded design. Another defining feature was the large Magirus logo the letter “M” with the Cathedral of Ulm incorporated within it, marking the location where Conrad Dietrich Magirus established the production site in 1864. The truck was also known for its distinctive engine sound you could hear it long before you saw it.

HOGRA used a modular “construction kit system,” where essential components were purchased separately. The goal was to build a truck largely made from foreign parts, yet tailored to the specific needs of Dutch transport companies. The early R6 engines were supplied by British manufacturer Perkins, while later models featured power units from Steyr in Austria.

Due to fierce competition in the Dutch truck market, HOGRA was forced to close its doors in 1961, and the distinctive trucks gradually disappeared from the roads.

At PAX, six HOGRAs were in service three tippers and three tractor-trailer combinations.
