2.1. Basic Parts and Operations

Try these first

1. 1.

   What is the optimal angle of swing for maximum productivity?

   Hint

   Think about the angle that minimizes movement.

2. 2.

   Define 'Height of Cut' in excavation.

   Hint

   Consider the position of the bucket during operation.

3. 3.

   What is the ideal angle of swing for excavators?

   • 80 degrees
   • 90 degrees
   • 100 degrees

   Hint

   Think about the minimum movement needed.

4. 4.

   True or False: Higher height of cut always leads to better productivity.

   • True
   • False

   Hint

   Recall how cut height affects effort.

5. 5.

   Given two scenarios where one has a truck located at 60 degrees and the other at 90 degrees angle swings, compare their potential productivity.

   Hint

   Consider how the swing angle affects the digging cycle.

6. 6.

   A project demands the excavation of soft material to a depth where the optimum height represents 40% of a maximum digging depth of 8 meters. Calculate the corresponding optimal height of cut.

   Hint

   Convert percentages to decimal fractions when calculating.
