Cummins Zambia has completed a coolant
plant project in Kitwe on the Copperbelt
that received approval from the Zambia
Environmental Management Agency
(ZEMA) in 2019.
The ‘plug-and-play’ plant will produce
two types of coolant, namely ES compleat
Hybrid (Blue) and ES compleat OAT (Red).
PLC-driven and automated, the plant has
the capability to carry out batch correction.
It has a blending capacity of about 1600ℓ
over two hours, including quality testing.
The system has two 2500ℓ product tanks
for product storage.
Originally planned to be completed
within six months in 2018, delivery

and manufacturing logistics ultimately
resulted in the project taking about a year
to complete, in addition to the stringent

main contractor was CP Engineering, with
a Cummins Filtration team overseeing the
project from start to finish.
maintenance cost. The rigging system
design also gives the operator better control
of the bucket and reduces the opportunity
for an inexperienced operator to damage it.
The unique trunnion design and location
on the clipped portion of the bucket protects
the lower hoist link from wear and provides
quick dumping of the payload. The design
includes a cast-in deflector to protect and
increase the life of the trunnion.
The new Cat bucket is available for a wide
range of dragline sizes and applications, no
matter what the brand of machine. Using
data-driven analysis, Caterpillar designs
each bucket for the specific dragline and
application.
The design process uses
all significant parameters,
including ground density, wear
package, rigging package and bucket weight to optimise performance
within the dragline’s rated suspended load.
Reduced dead weight of the double clip
back bucket, as compared to conventional
designs, ranges from 2 to 10% depending
on the application.
Cat dragline buckets also include wear
packages based on the mine’s material
abrasiveness and digging conditions.
The Cat dragline bucket lip nose casting
supports the Cat CapSure adapter and tooth
system. The system delivers long wear life
and hammerless installation of teeth for
enhanced safety and faster removal and
replacement.
Cat bucket boosts dragline
The patented design also eliminates the
high-maintenance spreader bar from the
rigging system.
The wide mouth, aggressive lip angle,
and low front height reduce drag power
required to fill the bucket. The design
minimises the required fill distance for
improved productivity and reduced bucket
wear. The unique shape of the rear wall
enables the bucket to fill without upper
rear corner voids, and it increases material
density in the bucket for optimum payloads
on every pass. It also clearly shows the
operator when the bucket is full and should
exit the cut.
Eliminating the hoist rigging spreader
bar has additional benefits, such as reduced
wear and tear on the top rails and trunnions.
Fewer system components result in less
inventory management and reduced
