▶ Sterling Hammer's advantage : 15% higher efficiency than the same class hammer

vs

VIBRATORY HAMMER vs STERLING HAMMER

Sterling Hammer’s advantage : 15% higher efficiency than the same class hammer

 Feature How to do & Effect
Centered double eccentric weights Unique design of centered double eccentric weights allow better durability of bearings
  Conventional hammer’s bearings Sterling hammer’s bearings
Distance from axis A A=B+C, B > C A=B+C, B = C
Center of gravity B and C ≠ A/2 B and C = A/2
Weight distribution “Bearing B” has more weight than “bearing A”. Weight of “A bearing” and “B bearing” is the same.
Effect Life time of both “A bearing” and “B bearing” is shorten due to imbalance of their weight. Longer life time of both “A bearing” and “B bearing”

Summary of Sterling Hammer’s selling point

 Feature How to do & Effect
“Auto Hold” function of Sterling Auto Tilt “Auto Hold” function on 90-degree tilt position
Compact design with no failure-prone cylinders of tilt function
Most powerful hammer in class Bigger and heavier eccentric weights make Sterling Hammer most powerful in class.
One class higher productivity and efficiency (15% higher than traditional vibratory hammers.)
Centered double eccentric weights Unique design of centered double eccentric weights allow better durability of bearings
Low maintenance cost Concise structure of components
Longer durability
