The Chinese excavator market show the recover indication at Jan, 2013
In January 2013, 28 excavator companies have sold total 4999UNITS in Chinese excavator market, down 4.25% on year-on-year basis, down 29.64% than Dec 2012. The excavators retail of the distributors reduces a little range in Chinese excavators market, it is about in 5%, consider the season requirements of Chinese excavators become weak in Jan 2013; we analyze the retail of Chinese excavators requirements will recover after the bottom.
Dec 2012, the second grade brand excavator distributors in order to get the rebate, enlarge the sale power, make a good sale result, it also affect the Jan 2013 sales, only sale 4999 units. But the excavator retails that is with the market reference significance recover after the bottom, shows the final excavator requirements of the construction stop the indication of weak.
The forecast of Jan, 2013, because the spring festival, Feb sales will reduce a big range than Jan 2013. but consider Chinese excavator market will meet the busy season of requirements in Mar 2013, and the stock of distributors is at low level, the distributors will enlarge the sale power in the busy season, so, they need to add the stock, so, the factory distribute sale will over the expect even effected by the spring festival.
The export of Chinese excavator keeps the high speed rising, export 675 units in Dec 2012, rise 95.65% on year-on-year base, higher than the average data of 2012.
The import of excavator become weak, Jan 2013, the top 9 brands excavator sale total 2502 units, down 17.26% on year-on-year base, down 15.47% than Dec 2012. The second grade brand and Chinese brand enlarge the sale power in Dec 2012, the foreign brand sale in Jan 2012 rise about 10 percent than Dec 2012.
In Jan 2013, the sale structure shows the bigger excavator rise in a big range, after the mine coal resource price become stable, and has one strong rise expect, the mine requirement will have one big recover rise. The big excavator has 11.6% range in the total sale, big higher than the 8% of the fourth quarter in 2012.
Excavators are heavy equipment consisting of a boom, bucket and cab on a rotating platform (known as the "house"). The house sits atop an undercarriage with tracks or wheels. All movement and functions of the excavator are accomplished through the use of hydraulic fluid, be it with rams or motors. Their design is a natural progression from the steam shovel.
Excavators come in a wide variety of sizes. The smaller ones are called mini or compact excavators. Caterpillars smallest mini-excavator weighs 3549 lb (1610 kg) and has 19 hp; their largest model weighs 187,360 lb (84,980 kg) and has 513 hp. The largest excavator available is the Bucyrus RH400, it weighs in excess of 2,160,510 lb (980,000 kg), has 4500 hp and has a bucket size of about (52.0 m3).
Engines inExcavators drive hydraulic pumps; there are usually 3 pumps: the two main pumps are for supplying oil at high pressure (up to 5000 psi) for the rams, slew motor, track motors, and accessories, and the third is a lower pressure (700 psi) pump for Pilot Control, this circuit used for the control of the spool valves, this allows for a reduced effort required when operating the controls.
The two main sections of an Excavators are the undercarriage and the house. The undercarriage includes the blade (if fitted), tracks, track frame, and final drives, which have a hydraulic motor and gearing providing the drive to the individual tracks, and the house includes the operator cab, counterweight, engine, fuel and hydraulic oil tanks. The house attaches to the Undercarriage by way of a center pin, allowing the machine to slew 360° unhindered.
The main boom attaches to the house, it can be one of 3 different configurations, Most are Mono Booms, these have no movement apart from straight up and down, some others have a Knuckle Boom which can also move left and right in line with the machine, the other option is a hinge at the base of the boom allowing it to hydraulically pivot up to 180° independent to the house, however this is generally available only to compact excavators.
Attached to the end of the Boom is the Stick (or dipper arm), the stick provides the digging force required to pull the bucket through the ground, the stick length is optional depending whether reach (longer stick) or break-out power (shorter stick) is required. On the end of the stick is usually a bucket. A wide, large capacity (Mud) bucket with a straight cutting edge is used for cleanup and leveling or where the material to be dug is soft, and teeth are not required. A general purpose (GP) bucket is generally smaller, stronger, and has hardened side cutters and teeth used to break through hard ground and rocks. Buckets have numerous shapes and sizes for various applications. There are also many other attachments which are available to be attached to theExcavators for boring, ripping, crushing, cutting, lifting, etc.
Prior to the 1990s, all Excavators had a long, or conventional counterweight that hung off the rear of the machine to provide more digging force and lifting capacity. This became a nuisance when working in confined areas. In 1993 Yanmar launched the worlds first Zero Tail Swing excavator, which allows the counterweight to stay inside the width of the tracks as it slews, thus being safer and more user friendly when used in a confined space. This type of machine is now widely used throughout the world.
