Shear legs, also known as sheers, shears, or sheer legs, are a form of two-legged lifting device. Shear legs may be permanent, formed of a solid A-frame and supports, as commonly seen on land and the floating sheerleg , or temporary, as aboard a vessel lacking a fixed crane or derrick.
A gun stabilizer must be used to compensate for the rocking motion. Due to the massive weight of a main battle tank, compared to an automobile, there is a much greater risk of breaking a torsion bar on sudden bumps or maneuvers, and if it is not replaced in short order the reduced suspension can affect the maneuverability of the vehicle, and in ...
With its three-leg mounting, the D-30 can be rapidly traversed through 360 degrees. Although no longer manufactured in the countries of the former Soviet Union, the D-30 is still manufactured internationally and is in service in more than 60 countries' armed forces. The barrel assembly of the 2A18 gun is used in the 2S1 self-propelled howitzer ...
This connector is present on newer heavy duty commercial trucks and trailers following the ISO standard and is intended to replace the combination of connectors according to standards ISO 1185 and ISO 3731. The 15-pin connector is not designed to replace the ISO 7638 connector. [18] #
A pick and carry crane is similar to a mobile crane in that is designed to travel on public roads; however, pick and carry cranes have no stabiliser legs or outriggers and are designed to lift the load and carry it to its destination, within a small radius, then be able to drive to the next job.
A leg mechanism (walking mechanism) is a mechanical system designed to provide a propulsive force by intermittent frictional contact with the ground. This is in contrast with wheels or continuous tracks which are intended to maintain continuous frictional contact with the ground.
An anti-roll bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is an automobile suspension part that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. It links opposite front or rear wheels to a torsion spring using short lever arms for anchors.
In the opposite extreme are extremely heavy duty tank recovery vehicles, and enormous ballast tractors involved in heavy hauling towing loads stretching into the millions of pounds. Necessarily, government and towing sector standards have been developed for carriers, lighting, and coupling to ensure safety and interoperability of towing equipment.
