subject: The Porter Of The Earth - Earth Movers [print this page] Heavy equipment refers to heavy-duty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations. They are also known as, construction equipment, construction plant, earth movers, engineering vehicles, or simply equipment. They usually comprise five equipment systems: implement, traction, structure, power train, control and information. Earth movers are devices which are used to dig, push, and transport earth. They are utilized on construction sites and in mines, among other locations, and the largest equipment requires the skills of a specialized operator who has received training both in driving and operating the device. Earth movers fall under the general category of heavy equipment. "Earth mover" is a bit of a misleading term as it has come to encompass any heavy machine that is used in construction, engineering and agricultural projects, from mining and excavating to bulldozing, farming and combat engineering. Specially designed for construction and engineering tasks, earth movers are also called engineering vehicles and construction equipment, specific terms that fall under the broader category of heavy machinery. Around the world, numerous companies specialize in operating earth movers and they can be hired to assist with site preparation and other activities. Contracting out this work can be more cost effective than retaining equipment and staff for earth moving, and the professional earth movers can often get the job done very quickly. These companies generally have a limited operational radius due to the expense and time involved in transporting their equipment to job sites. A number of manufacturers and companies make heavy machines like earth movers, from the well known Deere & Co. to Caterpillar and Bobcat. Some major players in the field of heavy machinery manufacturing include JCB, Komatsu, CASE, Ingersoll Rand, Hitachi, Atlas, Daewoo, Volvo, Demag, Koering, Pierce Pacific, Poclain, Skaggit, Kubota, The Liebherr Group, O &K, Terex, Timberjack and Madill. Many others exist as well, and the heavy machine engineering industry continues to boom throughout the US and the rest of the world. The world"s largest earth movers are used in mining. These heavy earth movers can seem more like buildings than vehicles, and they are capable of excavating and moving huge volumes of earth every day. They may come with a range of attachments which can be used in various settings, and some are designed to remain more or less fixed in place, digging out the ground around them as opposed to moving across a job site. Operators who work with this equipment must be especially careful, as the devices are often large enough to be capable of crushing vehicles and other construction equipment if they are operated unsafely.As the professional manufacturer of complete sets of mining machinery, such as Artificial sand washer,Secondary cone crusher,Ore processing plant, Henan Hongxing is always doing the best in products and service.Artificial sand maker:http://www.hxjq-crusher.com/58.html
