A powerful new vertical lifting and lowering
wedge with integrated handpump has been
announced by Enerpac for loads up to 16 tons
with very small access gaps. down to 10mm.
The compact, powerful and portable (10kg)
high-pressure (700 bar) LWC16 integral pump
lifting wedge is an extension of the LW-Series
family of lifting tools designed to safely lift and
lower heavy equipment during operations such
as machine maintenance and alignment, and
machinery installation and disassembly.
LWC16’s integrated hand pump, offers greater
manoeuvrability, operator convenience and safety
on more constrained application spaces, says
Enerpac national sales manager Darryl Lange.
The lifting stroke of 21mm (tip clearance 10mm/
maximum spread 81.5mm) is ideal for floor level
lifts, such as those encountered in industries such
as mining and energy, oil and gas, electrical distribution
and government utility (including water and
waste water and maintenance) as well as transport
and industrial workshop mechanical maintenance,
manufacturing, and infrastructure and construction
engineering tasks.
“This integral, sealed single-acting, spring-return
hydraulic unit is a convenient lifting solution with
quick configuration and set up, which saves time
by eliminating the need to make or break hydraulic
connections,” says Mr Lange.
Features of the LW series include:
• Each step can be spread under full load
• Unique interlocking wedge design with no first
step bending or risk of slipping out
• Includes safety block SB2
Enerpac’s new LWC16 integral pump lifting wedge
complements the global high pressure hydraulics
market leader’s comprehensive ranges of lifting
cylinders, pumps, pullers, presses, control technologies
and professional bolting technologies
widely used throughout Australia, New Zealand
and Papua New Guinea.
All Enerpac products are backed nationally by
its extensive service, sales and technical support
networks, optimising their uptime and safety in
service even in aggressive conditions and remote
locations.

GREEN ENERGY CLEANS UP
A far-sighted green energy initiative made
by the leading meat processor NH Foods
Australia at their Oakey Beef Exports facility
is paying handsome dividends in terms of cleaner
wastewater effluent, as well as a reduced fossil fuel
environmental footprint and lower energy costs.
The Global Water & Energy (GWE) COHRAL
(Covered High-Rate Anerobic Lagoon) plant was
installed at Oakey by Australian environmental
engineering and green energy authority CST
Wastewater Solutions, which recently inspected
the plant as it approaches its landmark fifth year of
service in southern Queensland.
It found the clean, compact and robust plant is in
outstanding condition, having required only routine
maintenance over that time as it continuously
produces 3000-4000 m3 of biogas a day, depending
on plant throughput. The generated biogas is directly
used in the plant’s existing boiler replacing natural
gas. This leads to replacement of fossil fuels and
sharpened cost-efficiencies at a time they are most
needed during the current Australia-wide drought.
The anerobic digestion plant extracts green energy
biogas from Oakey Beef Export’s wastewater
streams to replace millions of dollars-worth of natural
gas over its operating life, in Queensland’s Darling
Downs region.
Instead of effluent being stored in energy-costly and
extensive aerated lagoons used by many food and
beverage business – with associated environmental,
OH&S hazard, water and odour issues – waste at
Oakey is converted to biogas by a clean, green and
reliable anaerobic digestion process applicable to
any food, beverage or primary processing plant with
an organic waste stream.
The compact GWE COHRAL plant involved
occupies just half the footprint of comparable
covered anaerobic lagoons and a much smaller
space required by typical energy-hungry and
odorous open aeration lagoons in service globally,
says CST Wastewater Solutions Managing Director
Michael Bambridge.
The necessary pretreatment prior to the system lead
also to better recoveries of valuable protein and fats
which would normally end up in the wastewater.
This could be classified as an indirect benefit to
the bottom line as well as increasing reliability
Public Relations
by isolating clogging waste from the high
performance WWTP (Waste Water Treatment
Plant), says Mr Bambridge.
“By transforming a wastewater effluent treatment
and disposal problem into an ongoing productive
asset, the plant has achieved a rare business
and environmental ideal of cleaner, greener
performance with stable, predictable and profitable
supplies of biogas.
“The wind doesn’t need to blow and the sun
doesn’t need to shine to produce this green
energy – it is a highly viable renewable in its own
right, which complements the many excellent solar
and wind energy sources suited to other projects.
Ultimately, the plant will pay for itself with biogas
then go on to produce virtually free energy for
many years after that,” says Mr Bambridge.
“Right now, the Oakey plant is delivering cost-efficiency
benefits at a time when they are most
needed, when the plant has to operate efficiently
while coping with herd reductions resulting from
the drought. Its success is clearly demonstrating
the value in service of a technology that is widely
applicable to the food, beverage and primary
processing industry.”
The Oakey plant is designed to produce biogas
(primarily methane) which is stored for use in a
6000m3 capacity flexible PVC-coated polyester
storage balloon from which biogas is drawn to fuel
the boiler.
The new plant simultaneously delivers high quality
wastewater by extracting organic content, which
it converts into methane to replace fossil fuels.
The GWE technology involved removes 80-90%
of organic waste content, to give cleaner effluent
while also reducing odours.
“Oakey Beef Exports is one of the most modern
meat works in Australia and one of the country’s
largest beef export plants.
“Operating in a global market, as a premium
exporter to 34 countries, means its manufacturing
processes need to be respectful, sustainable and
efficient,” says Mr Bambridge.
The installation there of GWE COHRAL technology
deploys for the first time in Australia the covered
lagoon with the widely proven GWE anaerobic
technology used in more than 300 reactor (tank)
installations worldwide.
