Clamp Selection guide

The following clamp selection guide provides the general guidelines for selecting the correct clamp for the different types and sizes of piles

CLAMP OPTION SPECIFICATION

INTERCHANGEABLE CLAMP OPTION

Thanks to its interchangeable side clamp system, the Sterling Side Grip pile driver can handle all types of piles with its multiple clamps, and it offers quick transfer capability between various applications.    Round pile clamp(S) and round pile clamp(L) are an option.

Conventional pile driver vs Sterling Side grip

Conventional pile driver Sterling Side grip pile driver
Feature Auxiliary extended arm required
Fixed type mounting adapter or hydraulic reviving mounting adapter
No hydraulic tilting function of mounting adapter
No auxiliary extended arm required
Hydraulic revolving mounting adapter - 360 degree
Hydraulic tilting function of mounting adapter - tilting 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 excabator operator
Relatively high initial investment due to high purchasing price

CONVENTIONAL PILE DRIVER vs STERLING SIDE GRIP

- Sterling Side clamping

· 360-degree Swivel rotatable jaws enable precisely and accurately clamping    - Precise and accurate side clamping clamping

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

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



- Sterling Side grip’s advantage : 15% higher efficiency in its same class

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 bearign structure enable bigger eccentric weights to maximize vibratory power.
Conventional Pile driver’s bearings Sterling Side grip’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

- 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
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”
