Question

A hydraulic shovel is a common utility low production machine used for trenching below the track surface. True / False

Answer 1

The statement is false; hydraulic shovels, or backhoes, are not low production machines and are widely used for excavation with significant power derived from hydraulic and mechanical lever systems.

Step-by-step explanation:

The statement that a hydraulic shovel is a common utility low production machine used for trenching below the track surface is False. Hydraulic shovels, or more accurately, hydraulic backhoes, are typically used for various excavation purposes, but they are not characterized as low production machines for trenching. The statement is false; hydraulic shovels, or backhoes, are not low production machines and are widely used for excavation with significant power derived from hydraulic and mechanical lever systems.

Hydraulic and mechanical lever systems equipped in these machines, like the backhoe mentioned in Figure 11.42 and 11.48, are designed to provide significant power for digging, lifting, and moving materials. These systems utilize principles of fluid mechanics to transfer forces from one point to another, which is critical for achieving the mechanical advantage needed in heavy machinery operations.

Answer 2

True, a hydraulic shovel is a common utility machine used for trenching.

Step-by-step explanation:

True. A hydraulic shovel is indeed a common utility low production machine used for trenching below the track surface.

These are also called power shovels. They are designed for mining purposes and other vigorous digging tasks. Hydraulic shovels generally haul soil, minerals, rocks and other heavy materials or debris. They comprise a heavy boom with a lifting arm/dipper shovel attached that can pivot on the boom.

A power shovel (also stripping shovel or front shovel or electric mining shovel or electric rope shovel) is a bucket-equipped machine, usually electrically powered, used for digging and loading earth or fragmented rock and for mineral extraction.

A shovel is a tool used for digging, lifting, and moving bulk materials, such as soil, coal, gravel, snow, sand, or ore. A typical shovel. Most shovels are hand tools consisting of a broad blade fixed to a medium-length handle. Shovel blades are usually made of sheet steel or hard plastics and are very strong.
