Quick Summary

A dipper shovel is a type of power shovel used for hard digging and loading materials, particularly for truck loading. It features a robust, relatively short boom and a dipper stick that pivots, with a digging bucket attached. This bucket has a hinged bottom that the operator can open. The dipper shovel is considered the oldest and a very important excavating machine, with rail-mounted, steam-powered versions in use as early as 1835. It is most suitable when a long boom is not required and the ground is tough. A dipper dredge is essentially a power shovel mounted on a barge for marine applications, featuring a distinctive bucket and arm mechanism.12
