1 For what types of work is a Trenching Excavation Backfilling Loading
tractor-mounted backhoe suited?
2 Describe the two types of Wheel loaders Tracked loader
loaders?
3 Where would you use plate Plate tampers are used to compact soil in
tampers and blade tampers? smaller areas, such as sidewalks and floor slabs.
Blade tampers are used in confined areas or
narrow trenches.
4 Is it okay to move an aerial No; never move the unit with workers in the lift,
platform while workers are on it? especially if the boom or scissors are extended.
Explain your answer.
5 What equipment would you use Concrete pump truck
to simplify the placement of
concrete into forms and in hard
to reach places?
6 Which tool would you use to Jackhammer
break through concrete or
masonry?
7 What are cranes designed to do? A crane is a peice of hoisting equipment
designed to pick up a load, transport it a
reasonable distance and land it in a new
location.
8 What is the purpose of blocking Because the ground on most construction sites
when it is used with outrigger is soft, the outrigger float can sink with the
floats? extreme pressure and tip the crane over. The
outrigger floats must always be used with
blocking to distribute the load over a larger
area.
9 Why are tag lines used when The tag line stops the load from turning and
hoisting a load? allows workers to swivel or move the load to
avoid equipment or obstructions during the
hoisting procedure.

14 What are some advantages of Synthetic webbing slings have several
using synthetic webbing slings advantages. a) flexibility, which allows the sling
rather than wire rope slings to mould around the shape of a load keeping it
when hoisting loads? from slipping out of place. b) elasticity, which
minimizes shock and cushions the load. c)
softness and width, which reduce potential
damage to finished surfaces during hoisting
and reduce the risk of injury to employees.
15 Does a knot tied in a rope have Yes; a knot tied in a rope reduces its strength by
any effect on the rope's strength? 50%.
If yes, what is the effect?
