2. Pile driver - Wikipedia

   en.wikipedia.org/wiki/Pile_driver

   Pile driver, 1917. Ancient pile driving equipment used human or animal labor to lift weights, usually by means of pulleys, then dropping the weight onto the upper end of the pile. Modern piledriving equipment variously uses hydraulics, steam, diesel, or electric power to raise the weight and guide the pile.

3. Piling - Wikipedia

   en.wikipedia.org/wiki/Concrete_piles

   Hydraulic hammer is removable working equipment of hydraulic excavators, hydroficated machines (stationary rock breakers, loaders, manipulators, pile driving hammers) used for processing strong materials (rock, soil, metal) or pile driving elements by impact of falling parts dispersed by high-pressure fluid.

4. Screw piles - Wikipedia

   en.wikipedia.org/wiki/Screw_piles

   Modern screw pile design is based on standard structural and geotechnical principles. Screw pile designers typically use their own design software which has been developed through field testing of differing compression pile and tension anchor configurations in various soil profiles. Corrosion is addressed based on extended field trials ...

5. Miniature hydraulics - Wikipedia

   en.wikipedia.org/wiki/Miniature_hydraulics

   True working and functional miniature hydraulics follow the same operating principles and behavioral properties as their standard or regular size hydraulic prototypes, but are done so primarily at reduced sizes and pressures. Although uncommon, miniature hydraulics do exist, and are obtainable through a variety of sources.

6. Jackhammer - Wikipedia

   en.wikipedia.org/wiki/Jackhammer

   Contrast this with a steam, mechanical, or hydraulically driven pile driver. Advances in technology have allowed for portable hydraulic breakers. The jackhammer is connected with hydraulic hoses to a portable hydraulic powerpack: either a petrol or diesel engine driving a hydraulic pump; or a mini-excavator or skid-steer via a power take-off ...

   Some 1,350 feet deep and two miles across at its widest point, the Cortez open-pit gold mine outside Elko, Nev., looks like an asteroid crater—the largest hole in the ground you’ve ever seen.

8. Franki piling system - Wikipedia

   en.wikipedia.org/wiki/Franki_Piling_System

   Small charges of concrete can be added while the base is being formed [6] to enlarge the base and improve the pile’s settlement performance. [3] Franki piles can be installed raked (or sloped) with a tilt of up to 4:1. [5] Raked Franki piles are always reinforced and are particularly suitable for structures subject to dynamic forces. [1]
