Conveyors
Unlike cranes, which is a cyclic lifting machine, a conveyor (that is how this word is written) is a continuous machine designed to move bulk, lump or piece loads. The simplest conveyors, as well as cranes, have been used since ancient times. But, not afraid of this word, the conveyor made a coup in industry only at the end of the 19th - beginning of the 20th centuries, when it began to be massively used in production - in popular opinion, in Ford factories. The transition to the conveyor type of production made it possible to replace the highly skilled work of a collector, for example, a car, with a number of simple operations that almost anyone can perform after a couple of weeks of training. With the introduction of the conveyor, the advantages of division of labor were fully manifested. An order of magnitude increased productivity made the car not a luxury, but a subject of basic need, accessible and middle class. The ability to control the amount of output, and therefore profit, by simply increasing the speed of the conveyor, can also not but please the capitalist .
Those who happened to work on the conveyor claim that it pays off the monotony of constantly repeating operations quite a lot, but you have to pay for technological progress. With the help of conveyors, if you think carefully, you can completely automatically assemble some not very complex (and maybe complex) product. The use of industrial robots together with conveyors opens up great possibilities for automation of production.
Conveyors are most likely classified by even more parameters than cranes - screw, belt, rope, plate, etc., here it is not necessary to give the entire classification.
