In the turn of the 21st century, the issue on environmental awareness has evolved. The challenge on how to defeat environmental concerns such as climate change, depletion of resources, pollution and many others have hit hard on everyone even on the construction industry. Nowadays, project managers, engineers and people in the industry have thought of ways to incorporate their business into various environmental campaigns.

Buildings put a tremendous strain in the environment, being responsible for a significant share in pollution and other related issues and concerns that may affect our environment. Continuing the advocacy for healthier world poses great challenge to many construction agencies and businesses but it does not hinder their cause. They have built their equipment in response to the demands of Mother Nature. Their environmental friendly designs include:

Cleaner Equipment

Hitachi Construction Machinery introduced the ZW series equipped with clean but powerful engine to comply with Tier 3 and stage III A. Engine emission regulations effective in the U.S. EPA and European Union from 2006. Exhaust gas is partly re-combusted to reduce particulate matter (PM) output and lower nitrogen oxide (NOx) levels.

John Deere's new fixed chamber baler, on the other hand, is a great example of Deere's efforts to progressively lower the environmental impacts of its products. Deigned to reduce its impact on the field and more efficiently use resources, the baler delivers up to 24% better fuel efficiency is significantly faster than previous designs due to rotor feeder design.

Recyclable Machine

With a recycling-oriented society in mind, Isuzu upholds 4R practices throughout product-life cycles, as Isuzu increases recycling rates and reduces our environmental impacts. Recycled materials made from resin bumpers collected from end-of-life vehicles were used for four kinds of interior components including a console box. It became possible to use over 40% of bumpers from end-of-life vehicles by using new technology. Isuzu will be proactively committed to expanding use of some parts made from recycled materials.

For Hitachi, approximately 95 % of the ZW Series can be recycled. The resin parts are marked to facilitate recycling. The machine is completely lead-free. The radiator and oil cooler are made from aluminum and all wires are lead-less. In addition, bio-degradable hydraulic oil is available for jobsites where special environmental care is required.

Quieter Machine

Volvo Equipment also has its own share of low-emission level equipment. Their crawler excavator’s high breakout and crowding force is supported by an advanced hydraulic system that enables smooth, responsive digging and lifting.

Some people think that going green can be costly or difficult venture, especially in the construction industry but somehow, someone proved it to be possible. Construction companies like Axis Capital Group based in Singapore, are striving to pursue its eco-friendly campaigns, introducing only legit equipment and strengthening campaigns against fraud and scam that can further harm resources. Capital construction cities in Asia like Jakarta in Indonesia, Kuala Lumpur in Malaysia and Hong Kong continue to research and venture into more possibilities of further merging industrialization and nature.

In the beginning of the new millennium, the construction equipment market seemed to be at a crossroads, as existing equipment technology gets hold of a highpoint and new technologies started to arise. Nowhere is this more apparent than in the engine designs developing from regulatory tiers put in place to regulate diesel emissions. New and more highly engineered power sources have materialized with each tier, allowing equipment performance and functionality that some would have called impossible a decade ago.

(Axis Capital Group is servicing Southeast Asia countries such as KL Malaysia, Beijing China, Jakarta Indonesia and many more.)

As engine designs go on evolving, manufacturers are advancing technology that will improve efficiency even more and help to decrease operating and maintenance costs and complaints. Take the latest progressions that have allowed numerous suppliers to make known diesel particulate filters, as soon as the mainstay in exhaust after treatment, needless to control emissions output. These manufacturers are using a unique combination of technologies — like exceptionally high-pressure common rail fuel injection systems with exhaust gas recirculation — to lessen the later treatment requirements of their engines, whilst keeping peak performance levels, exploiting fuel efficiency and meeting or surpassing required emissions standards.

Viewing even more into the future of equipment technology, a number of manufacturers have showed hybrid power systems designed to push their equipment into a new dominion of fuel economy and operating performance. Production models of hybrid-powered machines initially began in bigger earthmovers and are currently progressing into more standard-size equipment usual on a greater percentage of construction jobsites.

In instance, full-size excavators are arising as the next springboard for hybrid power systems. The capability of hybrid systems to gain what was formerly measured as “wasted” energy during common functions like carriage swing is not anything short of revolutionary for an industry not frequently regarded by outsiders as a technology leader. Such advancements are demoted to high-production machines at this time, however as with other advancements, are intended to move around into more utility size machines as the industry and economics command.

Achievements reviews over the previous decade have pushed the construction industry to different heights in technological advancements and more is yet to come. Evidently, what we’re experiencing in terms of power system technology is simply the tip of the iceberg. The industry is composed to see giant leaps forward.
