1.2. Outline of Today's Presentation

Try these first

1. 1.

   What type of energy does the single acting hammer use for the upward stroke?

   Hint

   Think about what powers the lift mechanism.

2. 2.

   Name one disadvantage of the drop hammer method.

   Hint

   Consider its productivity compared to others.

3. 3.

   What is a drop hammer?

   • A mechanical crane
   • A hammer that relies on gravity to create impact
   • A type of vibratory equipment

   Hint

   Think about how the hammer is raised.

4. 4.

   True or False: The blow rate of single acting hammers is lower than that of drop hammers.

   • True
   • False

   Hint

   Recall the numbers we discussed for blow rates.

5. 5.

   If a crane must lift a total load of 25,000 kg (the pile and hammer together), what should be the maximum allowable weight for the hammer if the pile weighs 18,000 kg?

   Hint

   Think about total weight distribution during lifting.

6. 6.
