paralis

paralis
English: Translation
cylindrical objects, such as logs, bamboo poles and the like, used to reduce friction thus allowing heavy objects to be pushed or slid into position or another location with less effort
Notes

cylindrical items—often logs, pipes, or purpose-built metal/polymer cylinders—under heavy loads to reduce friction and allow easier sliding or rolling movement. As the load advances, rollers from the rear are moved to the front.

  Historically, this technique moved massive stones (e.g., for ancient megaliths or Egyptian pyramids), large timbers, or other heavy objects, with logs serving as makeshift rollers.
