Comparison and type of Vibratory hammers

	Sterling Auto Tilt type	Conventional Hydraulic Tilt type	"N” Company type
Feature	90-degree tilt / 360。hydraulic rotation function “Auto Hold” function on 90-degree tilt position	90-degree tilt/ 360。hydraulic rotation function Tilt function by hydraulic cylinders	90-degree tilt/ 360。rotation function
Strong point	More efficient and safer works Compact design with no failure-prone cylinders of tilt function Low maintenance	More efficient and safer works than non-tilt type vibro hammers	-
Weak point	-	Failure-prone cylinders for tilt function Higher maintenance costs Relatively expensive	Low vibratory power Many hydraulic lines forward to excavator

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

Conventional Hammer

Sterling Hammer

- Sterling Hammer is an existing most powerful hammer in the same class!
- Bigger and heavier eccentric weights make Sterling Hammer most powerful in class

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
