A First for


Van den Brink and his 4-member

team are specialized in earthmov-

ing, demolition, paving and much

more, and have many years of

experience in mobile crushing. His

aim when buying a new machine

was a 100% increase of the produc-

tion volume.

This objective was exceeded

by the Rockster R1100DS. Van den

Brink and Ophof got convinced by

live demonstrations in Austria, visit-

ing some existing Rockster custom-


Gerrit Ophof says

“Bert and I have a long-standing customer

relationship based on trust. He is open for new

ideas and has an excellent sense of the market

and his business. He knows the crusher industry

very well and has already tested equipment from

different producers.

Since there were no Rockster crushers in

Holland so far, we went to Austrian customers to

see the plants in operation and test them.”

More performance promises more profit

Almost all operations with crushing plants are calculated

per tonne of final material, therefore the optional weigh-

ing system was essential for Van den Brink.

The majority of his jobs are in the contractors business

for demolition waste and RAP. It’s very important for him

to easily move the plant from one jobsite to the other.

Thanks to compact dimensions and weight he manages to

transport the crusher also including screen box and return

belt without disassembly on a semi-trailer without any


Easy handling

A main reason for choosing a Rockster crusher was the

ease of use and the good accessibility, so any mainte-

nance work can to be carried out quickly.

“The hydraulic drive, the continuously variable

rotor speed and the sophisticated screening

system convinced me immediately. I can therefore

adjust the quality of the final grain to my

customer’s requirements very accurately.

The machine also features an innovative

main belt wear protection, which guarantees the

durability of the belt. We were able to immediate-

ly operate after delivery, producing about 140 t/ h

of 650 mm to 0-31,5 mm,”

explains Bert van den Brink.


West African Contractor Relies On Hitachi

Three Hitachi excavators are working on a $30 million

government-funded coastal defence project in Ghana.

Xara Developers has invested in two Hitachi ZX-

350LCH-3Gs and one ZX470LCH-5G for the construction

of a 2 km revetment along the Gulf of Guinea coastline.

Measuring 5.5

m high, it will

protect the town

of Aboadze, sur-

rounding commu-

nities and a near-

station, from

damage caused

by tidal waves.

The company

took delivery of

the three Hitachi

models in January

2015 from region-

al Hitachi dealer

DEM Ghana.

Each has a two-year/4,000 hour service contract. Head

Mechanical Engineer Jan Dekker explains the main rea-

sons behind the investment:

“Hitachi has been operating in Africa for a long

time. With such a time-sensitive project, we
