Term 1 of 26
Explain the importance of proper digger derrick positioning
They should be positioned randomly to allow for quick access.
They should be positioned at an angle to maximize reach.
They should be leveled using the outriggers. Out of level vehicles can increase the
weight on the turret and cause stability problems.
They should be leveled only when the ground is soft to avoid sinking.
Term 2 of 26

The tails must project at least six rope diameters for all rope 101" and under.
The tails must project at least six rope diameters for all rope 2" and under.
The tails must project at least eight rope diameters for all rope 1" and under.
The tails must project at least six rope diameters for all rope 1" and under.
Term 3 of 26
In what position is the boom strongest?
It is strongest when partially extended at any angle.
It is strongest when fully extended at its lowest angle.
It is strongest when fully retracted at its highest angle.
It is strongest when at a 45-degree angle.
,Term 4 of 26
What is the efficiency rating of a clove hitch?
It is 60% efficient
It is 50% efficient.
It is 35% efficient
It is 65% efficient.
Term 5 of 26
Explain the proper method of using a shackle and a wire rope sling in a choker configuration.
The load must be handled from the pin end and the center of the body. Never side load
a shackle.
The load must be handled from the side of the shackle for better leverage.
They should be leveled using the outriggers. Out of level vehicles can increase the
weight on the turret and cause stability problems.
The load must be handled from the bottom of the shackle to ensure stability.
Term 6 of 26
What is the insulation rating of a web sling?
Synthetic web slings are non-conductive but are not considered insulated
Synthetic web slings are both conductive and insulated, making them versatile.
It is 60% efficient
Synthetic web slings are insulated but can conduct electricity under certain conditions.
, Term 7 of 26
Which knot is often called the king of knots?
The fisherman's knot. it is designed for joining two fishing lines together.
The Bowline. It is easily untied after supporting a heavy load.
The clove hitch. it is primarily used for securing a rope to a post.
The square knot. it is used for tying two ropes together securely.
Term 8 of 26
When excavating on a slope, why should the spoils be placed on the uphill side?
The spoils should be placed on the side opposite to the operator for visibility.
Placing spoils on the downhill side helps to stabilize the backhoe during excavation.
If the spoils are placed on the downhill side it can risk the stability of the backhoe.
Spoils should be placed randomly around the excavation site for better access.
Term 9 of 26
What is the efficiency rating of a running bowline?
It is 50% efficient.
It is 55% efficient.
It is 25% efficient.
It is 65% efficient.
