Ruston Bucyrus 22-RB - Rodruza
Brick factory "De Zandberg" in Gendt (NL), part of the Rodruza group, owns two of these Ruston Bucyrus 22-RB draglines for digging clay.
The version shown on the photos is build from 1955 up to the eighties and in 2011 still daily used. The other 22-RB wasn't used anymore. Before 1955 the cranes were built with a more square cab.
The boom is here 50 ft. long, the maximum length is 70 ft.
The undercarriage isn't original anymore, this is an Interparts tractor undercarriage.
The clay for the bricks is digged from a hill which is made some months before. The clay is thrown in the GINAF tipper which brings the clay to the factory.
The GINAF F276 Turbo has a Gijsbertsen tipper body and was bought new.
The bucket has a volume of 750 litres.
The 22-RB was the succesror of the 19-RB. The biggest difference are the cone rollers, the 22-RB has two more of them.
From the years 73/74 there was an air control available for the 22-RB. Lateron this system was bettered with air cylinder in the anchor plates.
The hoist- and drag ropes ware mounted behind each other.
The factory engines were a Ruston & Hornby 4 cylindre water cooled or 6 cylindre air cooled and after the seventies a Caterpillar or Dorman.
The Ruston Bucyrus was still in the original RB colors.
This kind of cranes are today still used all over the world for dragline work.
