topic 6: heavy equipment Flashcards
() refers to large, powerful machines used in construction and earthmoving tasks.
Heavy equipment
An (), defined simply, is an engineering marvel designed for digging, demolition, and earth-moving tasks. It’s characterized by its long boom, the digging bucket attached at the end, and the cab atop a
rotating platform (the house), which sits on an undercarriage with tracks or wheels.

Construction, Demolition, Material Handling, Mining, Forestry, Landscaping, Disaster Cleanup, Dredging,
Road Construction
() can walk on water!
Excavators
Special amphibious excavators are designed to operate in swamps, lakes, and wetlands. They have pontoons or extended tracks that allow them to float and maneuver in waterlogged environments without sinking, making them crucial for dredging and wetland restoration projects
A (), commonly referred to as a dozer , is a heavy equipment machine that is seen frequently in large
and small-scale construction projects, road building, mining, quarrying, farming, heavy industry factories ,
and even occasionally military applications. Dozers are equipped with a metal blade mounted to the front that is designed for pushing material and are typically seen on continuous tracks.
bulldozer
A () is an earthmoving machine designed to push large quantities of rubble, soil, sand and other
loose materials. They were originally used by farmers as tractors to plow and clear land. Over time, they
have evolved to accommodate a variety of environments and applications with high levels of efficiency
bulldozer
The word “()” originally referred to a large dose or powerful person and was later used to describe machines that were used to push over trees and structures. It’s derived from the combination of “bull” for power and “doze” for the action of pushing.
bulldozer
type of dozers (3)
- CRAWLER BULLDOZER
- WHEEL BULLDOZER
- MINI BULLDOZER
type of dozers
Also known as a track bulldozer , crawlers feature a heavy plate used to load and push hefty objects. They are ideal for maneuvering over uneven surfaces and hauling heavy materials, and they work well in
applications with challenging terrain
CRAWLER BULLDOZER
type of dozers
Larger and more maneuverable than crawlers , () operate on a smaller axis and feature tires
for better handling.
WHEEL BULLDOZER
type of dozers
Also known as a compact dozer , () are smaller size and offer greater speed, maneuverability and versatility. They are ideal for maneuvering in tight spaces and performing quick work.
mini dozers
A () is a type of machine used to lift and move heavy objects. It is equipped with a hoist or a winch,
ropes or chains, and sheaves, and can be stationary or mobile. () are commonly used in construction,
manufacturing, shipping, and other industries
crane
type of crane
Used in tall building construction, () are fixed to the ground and have a vertical mast
tower cranes
type of cranes (4)
- TOWER CRANE
- MOBILE CRANE
- OVERHEAD CRANE
- CRAWLER CRANE
type of crane
These cranes are mounted on wheels or tracks and can be easily moved around a job site
MOBILE CRANE
