A 1/2" drive pistol-grip air impact wrench. An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft ...
An air ratchet wrench is very similar to hand-powered ratchet wrenches in that it has the same square drive, but an air motor is attached to turn the socket drive. Pulling the trigger activates the motor which turns the socket drive. A switch is provided to change which direction the socket drive turns. [1]
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ratchet is also used informally to refer to a ratcheting socket wrench.
Socket set with ratchet (above), four hex sockets and a universal joint. A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt.
ratcheting box wrench: ratcheting ring spanner: A type of ring spanner, or box wrench, whose end section ratchets. Ratcheting can be reversed by flipping over the wrench, or by activating a reversing lever on the wrench. This type of wrench combines the compact design of a box wrench, with the utility and quickness of use of a ratchet wrench.
A hydraulic torque wrench is significantly quieter, lighter weight and more accurate than pneumatic impact wrenches capable of similar torque output, making it an appealing alternative for many users to the very loud and cumbersome impact wrenches or torque multipliers which were formerly the only viable option for working with very large nuts ...
The cheater bar itself can become part of a de facto catapult with the worker in the line-of-fire. [1] If the over-torqueing results in the failure of any of the items in the jury rig, the fragments can injure workers in the line-of-fire. [2] The use of the cheater bar can result in component damage that can, in turn, harm workers. [3]
CAT D10N at work in Rishon LeZion, Israel. Among modern tractors, the High Drive (elevated sprocket) design was unique to Caterpillar products. The concept originated in 1914 with Caterpillar predecessor C. L. Best Tractor's 30 Humpback; [citation needed] this tractor was discontinued a year later, and the only other tractor to use the concept until the D10's introduction was the Cletrac Model ...
