ENVIRONMENTAL ISSUES Ӏ SPECIAL REPORT
Tadano prioritises going gReen for business activities and products
Crane manufacturer Tadano has explicitly made environmental protection and sustainability a priority: “We have established the clear goal that by 2030 we will reduce CO2 emissions from our business activities worldwide by 25% and our products by 35%,” says CEO Toshiaki Ujiie. Accordingly,
Tadano’s fleet will be gradually converted to engine technologies with zero emissions or at least significantly reduced emissions. An example is the ESTA-award-winning E-Pack, which makes local zero-emission crane operation possible. This electro-hydraulic unit, which is
intended to be connected to 400 V outlets with 63 A or 32 A, features an integrated 32-kW electric motor that enables Tadano AC 3.045-1 City and AC 4.080-1 cranes to work silently and with zero emissions. An advantage for customers is that the E-Pack can be used for various models in their fleets, which makes investing in this environmentally friendly technology a cost-effective choice. “We’re assuming that requests for
quotations asking for zero-emission operation, or at least significantly reduced emissions, will keep growing in the future. In fact, that’s already the case in the
j should be doing as a responsible business; it is very much in line with our values as a company.” The approach turned out to be about more than just reducing their own emissions. “We were breaking new ground because sustainability wasn't something that had really been developed to any great extent in the industry. A second element was engagement, because this isn't something any one company can do on its own. So we really need to reach out to work in partnership with our customers and with our suppliers and communities: it really needs to be a joined-up effort.” The final element, she says, is being a responsible employer. A key word, as with Professor
Drury above, is ‘efficiency’: “There is still a huge amount of space for us to be operating more efficiently. Every saving in fuel equates to fewer emissions. “We discovered that by far our biggest impact is the composition of our fleet. We have a massive fleet of equipment, and it's all running on diesel. So we want to focus on carbon emissions, and to

Netherlands and Scandinavia. And with the E-Pack, our customers will be perfectly prepared,” says Dr. Frank Schröder, all terrain crane product line vice president at Tadano. A large number of Tadano cranes can run on alternative diesel fuels. For the European market, this specifically means that all Tadano HK superstructure engines, all CC lattice boom crawler cranes, the GTC-1800EX telescopic boom crawler crane, and nearly every all terrain crane can be operated with paraffinic and synthetically produced diesel fuels in conformity with DIN 15940 without any modifications. This includes reduced- emission fuels such as HVO. Tadano is working on additional concrete
measures regarding environmentally friendly engine technologies for mobile cranes and will be providing information on them at the upcoming Bauma.
do that we need data. "We've been collecting data for a
while now... which lets us look at the basics in terms of fuel consumption, and therefore emissions, for each machine. We set ourselves clear targets: we said we will go to a 30% reduction in carbon emissions by 2030 – based on a 2018 baseline. “We are also aiming to have
30% of our hours of operation carbon neutral by 2030. So there's some quite ambitious goals there. “There isn't a well trodden path
for how to achieve this. Some of it is the cutting edge of technical research and development; some is just implementing obvious stuff like not running your engines unnecessarily. It is also again about working with other organisations. What I tend to say is that we have three main layers to the cake. The first layer is the options that are available now, that are already on the market. There are some hybrid crane equipment options available, and there is also HVO, which you can substitute for diesel. "We used that in a project last March, and it is a good transitional
option because you can use it straight away in diesel engines – you don't have to adapt them in any way. “We did testing before we carried out the project using it and the performance of the power packs that we used was not in any way inhibited by using HVO. You get the same performance but the carbon footprint of the fuel is far far less. Of course you have to be sure that the source material is sustainable: if your HVO comes from crops grown on destroyed rainforest, or on land needed for food, you are gaining nothing. The fuel we used is generated entirely from used cooking oil and wastes and residuals from the normal refining process. You have to trace everything back to its origin, or else have a trustworthy body to certify it. Ours has been certified by approved organisations – there are several - and I actually had the benefit of speaking to one of the academics who was involved in certifying it. “There are ways that you can
be reasonably reassured about the source of your fuel without having to dive into the entire supply chain f
