Water tractor beam. A tractor beam is a device that can attract one object to another from a distance. [1] The concept originates in fiction: The term was coined by E. E. Smith (an update of his earlier "attractor beam") in his novel Spacehounds of IPC (1931).
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.

The M915 and follow on M915A1 were a Crane Carrier Company design based on CCC's Centaur commercial tractor, built under contract by AM General between 1978 and 1982. The 1990 -A2 upgrade was a completely different truck: a Freightliner Trucks design with a different engine and transmission, hood and cab. Older models were upgraded to -A4 ...
These tractors may lift the coupling so the trailer legs clear the ground. A rigid truck and full trailer are articulated inside the cargo area length, so a semi-trailer can have a longer continuous cargo area. Because of this, a semi-trailer can haul longer objects, (logs, pipe, beams, railway track). This depends on the legislation; in some ...
The front beam axle was mounted on leaf springs, the rear tandem beam axles were mounted on a leaf sprung "walking beam" type suspension. All models shared a 181 inches (4.60 m) wheelbase (measured from the 1st to the 3rd axles). Full air drum brakes were used. The M123 was able to control the trailer brakes independently of the tractor.
Its products include tractors, combine harvesters, rice transplanters and tillers. Headquartered in Higashiizumo, Shimane, Japan, Mitsubishi Agricultural Machinery is a part of the Mitsubishi Group. Mitsubishi Agricultural Machinery was established in February 1980 from the merger of the Mitsubishi Machinery Co., Ltd. and Sato Machinery Co., Ltd.
The base designation identifies permissible gross vehicle weight and engine power output, the latter figure rounded to the nearest 10 hp (7.457 kW). For example, the HX range model 18.330 has a technically permissible gross vehicle weight rating of 18,000 kg and an engine power output of 326 hp (243 kW).
