A family-owned enterprise, A2C, has been working in
the field of sand and gravel extraction and further pro-
cessing for over 50 years.
Around 1.2 million tons are extracted from gravel
pits in the region of Île-de-France and supplied to con-
crete and prefabricated part plants.
The material for this is classically extracted using the
55 t duty cycle crawler crane using a dragline bucket.
With the attached 2.5 cyd dragline bucket, the driver
only needs 40 seconds to retrieve the gravel from a depth
of up to 10 m.
A new Sennebogen 655 duty cycle crawler crane has
recently started digging tons of sand and gravel in the
Île-de-France region of France. The French sales and
service partner, Sygmat, delivered the 55 t material
handler to the customer A2C matériaux.
Reliable, robust technology for
dragline bucket operation
The Sennebogen 655 HD's sturdy mechanical compo-
nents are particularly well-suited to dynamic tasks.
They include wide, robust sheaves which reliably
guide ropes and can withstand huge loads. A second
slewing gear comes into its own particularly when the
655 HD is used with a dragline bucket. As well as pro-
viding extra torque it also saves huge amounts of time
when emptying the bucket.
The newly-designed fair-lead keeps lateral movement
in the luffing rope to a minimum due to a pulley rope
guide in the lower boom section.
The dragline is equipped with a 261 kW diesel engine
that reliably drives the two 16 t free-fall winches. An
robust slewing ring and two strong slewing drives com-
bined with the 24.3 m long lattice boom make the ma-
chine suitable for gravel extraction
