MB Crusher has launched the fourth series of
its BF120.4 with increased production capacity.
The bucket has an operating weight of 4.8 tonnes
and can equip diggers with operating weights
starting from 30 tonnes. The simplified BF120.4
S4 has a maximum production of 53m 3 per
hour, with a load capacity of 1.3m 3 , and has a
new centralised lubrication system and lower
maintenance costs. New adjustment options have
also been introduced, increasing the range of sizes
available (from 15mm to 145mm). The bucket has
been strengthened where needed, resulting in
greater durability and shock-resistance and thus a
longer service life. The structural layout has also
been upgraded, allowing for faster speeds when
handling crushing operations.
EvoQuip has launched a new addition to its impact
crushing range: the versatile, fuel-efficient Cobra 230
impact crusher, suitable for construction and
demolition, asphalt recycling, quarrying, and contract
crushing. According to Matt Dickson, EvoQuip product
line director, the quick set-up times, simple intuitive
operation, and ease of transport make this machine
an ideal solution for all applications. The user-friendly
hydraulic assist, which comes standard, allows the
operator to adjust crusher settings easily without
tools. Powered by a fuel-efficient, high-performing
direct-drive system, the Cobra 230’s compact footprint
makes it ideal for working in urban areas. Ground-
level access to the engine, hydraulics, service, and
refuelling points, along with hinged radiator pack and
hinged diesel tank, ensure easy maintenance.

includes a closed-loop hydraulic
circuit, and a lowest-in-class
hydraulic tank volume further
optimises the machine’s efficiency.
At 30.9kg/cm, the Dynapac
CA255 boasts one of the highest
static linear loads in the
industry, and offers two different
amplitudes: 1.7mm for thicker
layers and 0.8mm for thinner
layers. The electronically operated
vibration reduces resonating
frequency, and efficient shock
absorbers keep vibrations on the
operator’s platform to a minimum.
The gas strut-mounted FRP
hood can be easily opened and
lowered to give complete access
to the engine, hydraulics, and
service points.
