JCB Unveils New Crusher Buckets
July 12, 2010
SAVANNAH, GA (July 6,
2010)--JCB Attachments has unveiled a range of crusher buckets designed to work
with the JCB line of tracked excavators, from the JS160 to the JS360. There are
three base models – the CB60, CB70 and CB90 – with two variants of each of the
larger models to suit the power and lifting capabilities of the JS crawler
excavator line-up.
Sustained Crushing
Force
Powered by the excavator’s standard
hydraulic breaker circuit, the crusher buckets use a fixed jaw in the base, with
a hydraulically-activated hinged jaw in the roof of the bucket. The gap between
the two jaws can be set with shims to determine the size of the finished
material.
The crushing action is achieved by the
hinged jaw being cycled in and out using an eccentric mounted on a shaft across
the top of the bucket. This shaft is equipped with substantial flywheels at each
end and rotated by a belt from the hydraulic motor.
The flywheels store energy from the motor,
smoothing out the power delivery and reducing stress on the machine. This action
also generates a more sustained crushing action, increasing
productivity.
Increased
Versatility
The CB60 is designed to work with JCB’s
JS160 and the JS190 and offers a capacity of 0.59yd3
(0.45m3). Two versions of the CB70 are available, both with a
0.78yd3 (0.60m3) capacity, to work with the JS220 and the
JS260 models. Likewise the CB90 offers two versions, for the JS260-360, both
have a 0.98yd3 (0.75m3) capacity.
Crusher buckets are capable of reducing site
waste, brick, demolition rubble or rock into a usable material, eliminating
haulage and disposal costs. They can reduce material to a hardcore size from
less than an inch to 4 and 3/4 inch (20-120mm), also offering a cost effective
alternative to an on-site mobile crushing plant.
They are particularly useful in demolition
applications, providing an on-site recycling resource and boosting the
versatility and utilization of the JCB excavator. Even demolition waste with
reinforcing steel present can be crushed, allowing the steel to be removed and
recycled.
Built To
Perform
The JCB crusher buckets have 30 hour
greasing intervals with just two lubrication points. They are performance
matched to the JCB excavator range. Each crusher bucket carries its own JCB
warranty and is fully covered by JCB’s renowned after sales support
service.
