CONVENTIONAL PILE DRIVER vs STERLING SIDE GRIP

Conventional pile driver

Sterling Side grip pile driver

	Conventional Ripper’s bearings	Sterling Ripper’s bearings
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

Conventional pile driver

Conventional pile driver Sterling Side grip pile driver

	Conventional pile driver	Sterling Side grip pile driver
Feature	Auxiliary extended arm required Fixed type mounting adapter or hydraulic reviving mounting adapter No hydraulic tilt function of mounting adapter	No auxiliary extended arm required Hydraulic revolving mounting adapter - 360 degree Hydraulic tilt function of mounting adapter - tilt degree ±30
Strong point	Low price	Cost effective : Quicker piling up to by 30% than conventional pile driver Versatile : · Piling at headroom construction site and piling at confined space job site · Wide ranges of piles Sheet piles, H beams, l-H beams, and round-piles Safe : · A single excavator operator required, no need ground crew or assistant needed
Weak point	Impossible piling at headroom job site, and at confined space job site A ground crew or assistant required besides an excavator operator	Relatively high initial investment due to high purchasing price

Sterling Side clamping

360-degree Swivel rotatable grip pads enable precisely and accurately clamping - Precise and accurate side clamping clamping

Conventional Side grip clamping unit

Four clamping pads with two separate arm structure may cause inaccurate clamping. Frequent inaccurate clamping may lead to crack or damage of clamping cylinder and clamp arm

Sterling Side grip clamping unit

The jaws 360-degree swivel, which enable to grab as pile in the corner it pivots and holds. It results in precise and accurate clamping

- Solution of Sterling Ripper for Vibratory Ripper’s drawback

Solution	How to do & Effect
Centered double eccentric weights	Unique design of centered double eccentric weights allow better durability of bearings

Conventional Pile driver's bearings

Sterling Side grip's bearings

	Conventional Pile driver's bearings	Sterling Side grip'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”
