dump truck belaz-75710 | Shovel is a kind of mechanical shovel collection

In iron ore mines, shovels play a key role in loading and moving minerals. Cable shovels are usually used in these mines due to their high power and ability to load large volumes of material. Also, hydraulic shovels are used to load lighter minerals and soils
Advantages of Shawl:
Guiding the cup is simple
It loads from bottom to top and vice versa
Evacuation is done without moving the chassis and only by rotating the mast and chamber
Accepts stone practically with large dimensions
It is resistant to stone walls due to its large size and strength
It also settles on loose surfaces (floors).
Disadvantages of Shawl:
The cost of buying it is high.
It needs minimum load to work economically.
Its repairs are expensive.
Due to the low maneuverability, there should be enough space for loading
