Tractor beams and pressor beams can be used together as a weapon: by attracting one side of an enemy spaceship while repelling the other, one can create severely damaging shear effects in its hull. Another mode of destructive use of such beams is rapid alternating between pressing and pulling force in order to cause structural damage to the ...
The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles.
Alternatively, the pivot could be fitted to the front of the beam and the racers at the rear, allowing the gun to fire through an embrasure. The traversing beam sloped upwards towards the rear, allowing the gun and its carriage to recoil up the slope. [6] A Danish cannon on a typical 18th century field carriage.

The Safeguards Transporters and Safe Secure Trailers were designed by the Sandia National Laboratories and built on the frame of commercial Peterbilt 18-wheel tractor trailers in about 2000. The Safeguards Transporters replaced what was later revealed to have been the first generation of Department of Energy nuclear weapons carriers. [1] [2] [3]
Scientists built a working tractor beam—the first example of one that pulls objects visible to the naked eye. That's a huge deal.

An artillery tractor, also referred to as a gun tractor, is a specialized heavy-duty form of tractor unit used to tow artillery pieces of varying weights and calibres.
Due to the limitations of requirements and resources, the tank was a functional failure. By using a large tractor as a base, and bolting on a hastily designed and poorly constructed tank superstructure, the resultant tanks were inadequately armored, extremely heavy (20–25 ton), unstable, restricted by tractor gearing to slow speeds, and had to stop to change gears.
