▶ 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
Double bearing structure Unique design of double bearing structure allows at least 2 times longer life time of bearings
Double bearing structure enables bigger eccentric weights to maximize vibratory power.
  Conventional Hammer’s bearings Sterling Hammer’s bearings
Number of bearing Single bearing per each side of axis Double bearing per each side of axis

Advantages
- High vibratory power at the same size of bearings
- At least two times longer life time of bearings
- Higher durability at hard-rock job sites

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 Tilting “Auto Hold” function on 90-degree tilting position
Compact design with no failure-prone cylinders of tilting 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.)
Double bearing structure Unique design of double bearing structure allows at least 2 times longer life time of bearings
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
