Company
Profile
Rockcrush is a private Australian-based company
that designs and manufactures dredges, winches
and cable-handling equipment for domestic and
limited offshore markets.
Rockcrush was established in January 2009 when
the owner, John Goulding, bought the well-known
winch and dredge business, Jaden Engineering. With
more than 30 years in the industry, the Jaden name is
synonymous with quality, reliability and performance.
Rockcrush has its headquarters and workshop facilities
in an industrial estate on Queensland’s Gold Coast. The
company has assembled a highly capable team of skilled
technicians, and has established relationships with
a range of suppliers drawn from the local area, as well
as nationally and internationally.
The company is focused on manufacturing high quality,
reliable and durable products which are designed to
meet clients’ specific requirements at fair market prices.
Rockcrush has also developed successful outsourcing
arrangements where it is deemed more efficient than
providing capabilities in house.
Client service is a central tenet of the day-to-day
operations of the Rockcrush. The company measures
success in terms of client satisfaction. Everyone at
Rockcrush, from the executive level right down the line,
is genuinely committed to providing quality products
and excellent customer service.

1 Tonne
Coaxial Winch
This Rockcrush winch system comprises
one 1 tonne winch and tethered pendant
control system. The hydraulics allow “highlow” operation: high line speed at low line
pull or low line speed at high line pull.
The winch is equipped with Archimedes
screw wire feeder to automatically maintain
proper spooling of the wire on and off the
winch drum.

Dredge
The C series Rockcrush Dredger range has been
specifically developed to meet the requirements
of the mining industry. These dredgers operate
under very harsh conditions and are structurally
reinforced to enable operations staff to drag the
dredgers from slurry and settling ponds onto the
surrounding hard rock embankments either for
maintenance purposes or recovery from blast
areas. These dredgers come in three frame sizes,
1500, 1200 and 1000, and input power ranges from
100 kW (130 HP) to 600 kW (800 HP).

UNDERLYING DESIGN PRINCIPLES
Operation
»» Simplistic but efficient
»» Safe
»» One-man operation,
operator friendly
Structure
»» Engineered to sustain performance
»» Modular sections to enable quick

»» Hulls comply with USL code

The bottom hull plate on the pontoons of C series
dredgers are twice as thick as that of the standard
dredgers to prevent damage by sharp objects.
The design is a three-piece modular dredger with
each module being truckable. Two side pontoons
required for floatation and stability, and one centre
pontoon housing the engine room, fuel and oil
tanks and operators cabin. The design enables quick
dismantling and assembly for transportation. The
assembled unit may be transported short distances
on a low bed vehicle.
Traditional keel cooling has been removed from
these dredgers reducing the damage risk to cooling
tubes during skid removal of the dredgers from
ponds. Cooling of the main engine and hydraulic
oils are achieved through air coolers fitted in the
engine room.

The 250 Series Booster Station is a self-contained
diesel driven slurry pump booster. This is located
in the discharge line between the dredge pump
and discharge point. The booster pump adds head
pressure (energy) to the dredge system so that
maximum production can be maintained as the
pipeline is extended.

A range of Rockcrush cutting heads are available for
these dredgers. The standard disc cutter range has
been developed over 35 years to offer a versatile
hardwearing cutter capable of dredging materials in
sand, clay and rock shale.
This range of dredger offers management further
cost benefits through operational staff number
reductions. Being a fully computerised electro/
hydraulic control system with radio telemetry
communication and controls, management have
access to data recording and reports on daily/hourly
operational achievements.
