Excavators and loaders: heavy duty market leaders
Excavators and loaders: why they are so popular
Among all the heavy duty machinery available on the market, excavators
are probably the most popular in USA and by far some of the most frequently used pieces of equipment. The reasons are obvious: those machines guarantee one can make the most out of their work due to their versatility and the ability of multitasking, accompanied by high productivity. It also goes without saying that the more tasks a machine can perform, the less pieces of specialized equipment are needed by the contractors.
Real monsters for impossible tasks
For extreme works like transforming landscape, bulk earthmoving or heavy lifting – large excavators are absolutely essential. Some of them are real behemoths - operating for 24 hours a day in a highly challenging environment or tough conditions, usually used for construction, earthmoving and mining. Powerful but economical engines provide an outstanding loading and excavating capacity, working reliably and allowing to keep the running costs low.
- Terex RH 400, the world’s largest hydraulic shovel could be a good example. It weighs 1078 tonnes and has a stunning shovel capacity of 94 tons in a single scoop! That excavator has the working ability to scoop up around 9900 tons of material every hour – which is undoubtedly the world’s record for a vehicle of that class that hasn’t been broken so far.
- The heftiest excavators in the world also include Bucyrus RH400. Weighing almost 889 tonnes metal gigant is now manufactured under Caterpillar brand, however it was originally launched by Terex. If you are up to real challenges in the construction sector, you would be in awe when confronted with
- SLJ900/32, a mobile bridge erecting machine! That beast weighs 580 tonnes, is 91.8 meters long and 9 meters high. It builds bridges without conventional crane technology – instead, the machine approaches the edge of the bridge reaching out to towers that need to be connected to the bridge with a temporary track. When it’s stable, the bridge building machine pulls itself out with the new bridge segment. The process can be repeated several times until the job is done.
Dozers and pipelayers
Heavy construction industry is not all about excavators and loaders. There are some other powerful machines used for the work outside: dozers and pipelayers
. Dozers are crawlers, fitted with a metal plate, referred to as blade, used for pushing large quantities of earth, sand and debris. At the rear they usually have a mechanical device resembling claws (a”ripper”) specialized at loosening densely compacted materials. Dozers work mainly in the utility system and building construction sites but also in mines, quarries, heavy industry factories and farms. As for their component design, they regularly undergo modernization processes which means that innovations and improvements on that field are inevitable. Dozers
do great job in building construction and waste management industries and they will continue to serve that purpose for many years to come as there are no reasonable replacement for those heavy duty machines.
Construction fairs and exhibitions
If you would like to know more about what’s new in the construction sector, what new technologies are being developed and applied, you can’t miss the CONEXPOAGG
show during which every major construction industry is represented by some among the 2,800 exhibitors who take part in the fair. During 4 days of show you can attend an education session of your choice, out of 150 available including asphalt, lifting, mining, concrete, aggregates, utilities and so on.
The next show is scheduled for March 10-14, 2020 in Las Vegas, Nevada
and it is going to shed some light on the business management as well as the future of equipment technology in the aspect of construction sector.
Yet another example of the interesting gig that you can consider worthwhile is the Oklahoma Excavation Safety Expo
. It’s the “it” place to be for the professional contractors and excavators, underground facility operators and other people working in the safety industry. During the event they can exchange know-how, educate and share their creative ideas about how to preserve safety and the highest quality standards of digging.
