THE ALL NEW SHEET PILE DRIVER FROM NPK

NPK’s all new excavator-mounted sheet pile
driver is a modified design of industry leading
plate compactors, adapted to direct powerful
vibration forces downward, optimizing driving
of sheet pile. Durable, shock-absorbing rubber
mounts protect the excavator’s boom and stick
from vibration and shock loading. The mobility
and maneuverability of NPK sheeting drivers
permit operation in many areas previously
inaccessible: under low clearance obstructions
(bridges, etc.), around bridge piers, and next
to walls. This makes picking up, moving and
aligning the sheeting easy and stress-free
when driving and/or extracting. Designed for
excavators
from 16,000
lbs. to
100,000 lbs.

Key Features and Benefits

• 180° free rotation allows precise alignment and positioning of the sheet
pile without having to reposition the machine. When not needed the swivel
can be locked into place; either parallel or perpendicular to the boom.

• Dedicated top mounting brackets, designed to OEM bucket specifications,
provide a full range of motion when picking up the sheeting from the
ground.

• Simple operation means that any excavator operator can easily drive and
extract piling.

• Clamp fitted with a hydraulic cylinder lock to prevent slippage.
• Shock-absorbing rubber mounts isolate vibration and reduce noise.
• Heavy duty, high efficiency gear motor.
• Integrated flow control and pressure relieving valves protect from

excessive flow and pressure.
• Oil splash lubrication eliminates routine greasing of the bearing.

Only want to install
your pilings once?

DUROSLEEVE is the answer!

• Encase your pilings with impenetrable PVC
• Keep worms, insects & rot away from wood
• Easy to install and comes with a 50 year warranty

Shoreline Plastics has developed
the ultimate in marine piling
protection, the DuroSleeve.
The DuroSleeve is made from highly-
durable, shrinkable PVC that completely
encases the wooden piling or timber in
a PVC shell that is impervious to the
elements. Unlike conventional piling
wrap, the DuroSleeve has no joints or
seams to compromise the integrity of
the piling protection. The DuroSleeve
will keep CCA chemical contaminants

Grindrod’s Terminal de Carvão da Matola
(TCM) operates an open storage dry-bulk
terminal in Mozambique which has an
export throughput capacity of 7.5 million
tonnes, handling magnetite and coal. It is the
port’s first terminal to take full advantage of
the dredging initiative with the completion
of the Berth Deepening and Quay Offset
project
Grindrod works closely with Caminhos de
Ferro de Mozambique (CFM) and Transnet
Freight Rail to create export capacity for
both the established and Junior Coal Mining
community of Southern Africa.
Subtech Norte Limitada was awarded the
Quay Offset project. It involved dredging the
berth pocket, scour protection of the quay
wall and installation of a new fender spacer
system. The fender support structures were
designed and built by Subtech, together
with the new fender systems which Subtech
ordered from ShibataFenderTeam.
ShibataFenderTeam manufactured and
supplied six SPC 1600 Grade G1.1 Fender
systems, each system comprising of a SPC
1600 rubber Cone Fender, a closed box
fender panel fitted with UHMW-PE low
friction face pads, a set of cast-in anchors,
tension and weight chain assemblies, chain
brackets and all fasteners plus one set of
spare components.
Subtech completed this contract on 3 July
2017, which involved the installation and
commissioning of the new fender support
structures and new fender systems within
a 19 calendar day operational shutdown
period of the existing quay, which was a
remarkable achievement.
The project was designed to extend the
quay by a 8.5 meters offset, while the
