  • Mast arrangements with a mast which has a linear guide on its front side for the sliding guidance of a work carriage are frequently used on construction machinery, as can be seen from the publication DE 84 35 121 U1 is known.
  • a rotary drilling drive, a vibrator or a ram can be arranged on the work carriage in order to carry out a civil engineering process.
  • the mast assembly is usually mounted on a preferably mobile carrier device via a linkage mechanism.
  • the linkage mechanism allows the mast assembly to be adjusted vertically to a certain extent.
  • the mast assembly is designed to be as tall as possible in order to accommodate correspondingly long drilling tools, bored piles, or sheet piles.
  • the mast assembly may extend as far down as possible, close to the ground surface.
  • the linkage mechanisms on construction machinery are not designed to lower a single mast or leader assembly close to the ground surface, for example due to the design of the carrier device.
  • relatively long work tools such as a sledgehammer for driving planks, to increase the travel range along the mast.
  • a mast extension to the underside of a base mast.
  • Such a mast extension can usually have a length of 1 to 3 meters.
