IPAF SUMMIT
Tim Hatch, who, at the time of the Summit, was vice president of global engineering at JLG Industries, but
has now left the company, spoke about the challenges faced by the changing emission laws. Legislation
on diesel engine exhaust emissions in the off-highway sector will take another step in 2014 when
the European Stage IV and the broadly equivalent US Tier 4 final laws start to come into force for new
equipment. “The added complication is that different parts of the world are moving to these standards at
different times,” said Mr Hatch. In 2011, Europe
and North America moved to Tier 4 interim, with
the rest of the world running on lower Tier levels,
he explained. “As we move to 2016 we see that
Europe and North America move to Tier 4 final,
while China and India should be moving to Tier
4 interim; although I have heard recently from a
major engine manufacturer that China won’t move
to a Tier interim but will move to a new standard
between Tier 3 and Tier 4 Interim, which will add to
the complication.
“As an OEM this means we have to provide a
higher regulated engine and a less regulated one,
with different ratings for different parts of the world
for the same machine.”
“Stage I saw fairly simple changes to the inside
of engines with a fairly low cost. Stage II started
to get a little more complex with electronic fuel
injection and EGR exhaust gas recirculation. Tier
4 final moved to more electrics, high pressure
common rail fuel system, exhaust gas recirculation,
and diesal oxidation catalysts fitted to the machine.
That’s standard on an aerial and pretty much
the same as the Tier 4 interim on telehandlers
introduced last year.
“One of the big challenges is the increase in the
heat rejection from the engine in the region of 30%
more by a Tier 4 interim engine, which drives us to
bigger cooling packs as well as all the other things
we are packaging under the engine.”
INSIDE CHALLENGES
Tim Hatch, former vice president of global
engineering at JLG Industries
Sérgio Kariya, managing
director of the rental
division of Mills in
Brazil, introduced lean
manufacturing at its facilities
initiatives, rather providing checklist-like
standards to follow, OSHA decided a full
outreach programme was required to ensure
that employees know about fall protection
standards.
This is particularly aimed at so-called
venerable workers, that might not speak
English well, or day labourers that go from one
jobsite to another in a matter of weeks or days.
The agency is producing easy-to-understand
materials explaining workers’ rights to training
and a safe working environment when it comes
to working at height.
The initiative sees OSHA working with
trade associations, construction unions and
community and faith-based organisations,
among others. In many cases the latter two take
the place of unions where they have lost their
grip on communities over the years.
Bolstering Brazil
One way that a company can set itself in the
right direction is through lean manufacturing.
It is a fact that many companies have already
gone down this road, and are now feeling
the benefits. One of them is Mills Rental,
Brazil’s largest general rental company and
the continent’s biggest provider of access
equipment. Sérgio Kariya, managing director of
the rental division of Mills in Brazil explained
the challenges associated with introducing
such a scheme in Brazil, and showed how the
company saved huge costs by going through
this process.The company also set up an
impressive training scheme to train managers
of the world’s biggest mining company VALE,
to ensure their team members understand
and followed best practices when its came to
operating MEWPs. See the training feature on
page 45.
