Consider the following when designing mounting brackets
Required plate thicknesses.
Correct transport position of the hammer.
Most common hammering position, in which the bucket cylinder is in the middle
position.
Mechanical stops to protect the bucket cylinder when the hammer is fully in or
out
Placement of the pin holes on the mounting bracket hinges. Normally, they are
placed almost symmetrically from the hammer center line.
Height of the stick's mounting bracket pin from the mounting bracket bottom
plate (A). The height depends on how close the pin is to the hammer center line.
The closer it is, the longer dimension (A) must be.
Effect of hammer recoil and feed force on the bucket cylinder, which should be
