Minecarts range in size and usage, and are usually made of steel for hauling ore. Shaped like large, rectangular buckets, minecarts ride on metal tracks and were originally pushed or pulled by men and animals (supplemented later by rope-haulage systems). They were generally introduced in early modern time, replacing containers carried by men.

The tail-rope system had its origins on cable-hauled surface inclines prior to the 1830s. [26] This was the dominant system in the 1880s [ 27 ] Frequently, one engine was used to work both ropes, with the tail rope reaching into the mine, around a pulley at the far end, and then out again.
The Cowlairs incline was an example of this, with a continuous rope used on this section from 1842 until 1908. The middle section of the Erkrath-Hochdahl Railway in Germany (1841–1926) had an inclined plane where trains were assisted by rope from a stationary engine and later a bank engine running on a second track.
An optional final stage for the permanent protection of "served" rope is to paint the outer layer of twine with a mixture of tar, varnish and black paint. This needs renewing periodically, and going aloft to paint footropes , shrouds , stays , and other served rigging is one of the regular maintenance tasks on many tall ships .
The line originally used wooden rails and a hemp haulage rope and was operated by human or animal power, through a treadwheel. [9] The line still exists and remains operational, although in updated form. It may be the oldest operational railway. [10] Minecart shown in De Re Metallica (1556). The guide pin fits in a groove between two wooden planks.
The earliest form of cable railway was the gravity incline, which in its simplest form consists of two parallel tracks laid on a steep gradient, with a single rope wound around a winding drum and connecting the trains of wagons on the tracks. Loaded wagons at the top of the incline are lowered down, their weight hauling empty wagons from the ...
Principle of rope-shovel operation. [1]A power shovel, also known as a motor shovel, stripping shovel, front shovel, mining shovel or rope shovel, [2] is a bucket-equipped machine usually powered by steam, diesel fuel, gasoline or electricity and used for digging and loading earth or fragmented rock and for mineral extraction.
