Primo, quod CAVATOR fuit manual, et fuit plus quam CXXX annis de invention ad MMXIII. Per tempus, quod habet peritoso Development Duci et Internum Technomechanical Hydraul CAVATOR Technology. Primum Hydraulicorum CAVATOR feliciter inventa in Birkland Factory in Gallia. Ob ad applicationem de hydrau technology, in 1940s, ibi erant hydrau backhoe tentorium excavators in tractatores. In MCMLI, primum plene hydrau backhoe excavator erat launched a Poclain (Bokland) Factory in Gallia, sic creando novum spatium in agro CAVATOR technology progressionem. In primis et medium 1950s, puppes plenus gyratorius hydraulicorum CAVATOR et Crawler plena Hydraulica CAVATOR EXERCITATIO successive. Initial Trial productio Hydraulicorum CAVATOR est Hydraulica technology de aircraft et machina instrumenta, indigentiam hydrau componentibus apta variis operantes conditionibus CAVATOR, vestibulum qualitas non firmum et accessiones non perficitur. Cum autem 1960, Hydraulic CAVATOR habet ingressus in scaenam de promotionem et strenuus progressionem, Excavator Manufacturers et varietates in variis regionibus auctus cursim et output est. De MCMLXVIII ad MCMLXX, in output hydraulicorum excavator reputatus ad LXXXIII% de totalis output de CAVATOR, prope C%.
Prima Prima Prima Excavator: et cessum Electric motor et internum combustione engine, ut ad CAVATOR habet provectus et apte electrica cogitationes, ita a varietate excavator products sunt natus. In MDCCCXCIX, primum Electric CAVATOR apparuit. Postquam Mundus Bellum I, Diesel Engines etiam in excavators et mechanica CAVATOR repulsi ab Diesel Engines (seu Electric motricium) fuit prima Excavators.
Secundum generatio Excavator: cum extensive usum hydrau technology, in CAVATOR habet plus scientific et locum traductionem machinam, Hydraulicorum transmissione pro mechanica tradenda est a magnus saltu in excavator technology. In MCML, primum Hydraulicorum CAVATOR natus est. Mechanica transmissio hydrau pressura est secunda generatio Excavator.
Tertio Excavator: Electronic technology, praecipue computatrum technology, ita ut CAVATOR habet automatic imperium ratio, sed etiam ut CAVATOR ad altum perficientur, automation et intelligentes directionem progressionem. Germinatio Mechatronics Tulit est circa MCMLXV et MechaTrons technology pro masdra-productum hydraulicorum excavators erat usus circa MCMLXXXV, cum principalis ad salvandum industria. Electronic Excavator est symbolum tertia generatione Excavator.
Excavator industria manufacturers potest esse fere dividitur in quattuor genera. Plus quam LXX% de domesticis excavators sunt occupati ab aliena faces, et domestica brands sunt adhuc maxime parva fodiendo et medium fodiendo, nisi participes domesticis excavators est paulatim, cum anno-in-anno augmentum 3,6% in anno, in anno-in anno crescit 3,6 in anno-in anno, in anno, in anno, in MMXII.
Cum sero 20th century, in internationalis productio excavators est developed ad directionem magnarum, miniaturization, multi-munus, specializatione et automation.
I. develop multi-varietate, multi, eget, summus qualitas et summus efficientiam excavators. Ut in occursum necessitates municipium constructione et farmland constructione, micro-excavators cum situla capacity infra 0.25M³ sunt developed foris, et minimum situla capacity non solum 0.01M³. In addition, the largest number of small excavators tend to a machine, equipped with a variety of working device —— in addition to the shovel, shovel, also equipped with lifting, grab, flat bucket, loading bucket, rake teeth, broken cone, twist, drilling, electromagnetic suction cup, vibrator, push board, impact shovel, fork, aerial frame, hinge plate and shovel, etc., to meet necessitates variis constructione. Simul, in progressionem specialis usu specialis excavators, ut humilis specifica pressura, humilis strepitu, underwater speciale et amphibious excavators.
II. Celeri progressionem plenus hydraulicorum CAVATOR, continua emendationem et innovation of potestate modus, ut EXCVATOR ex Simple Vecte Operatio ad Hydraulicarum potestate et electrica imperium, radio potestate, electronic computatrum integrated progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum integrari progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum integrari progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum integrated progressio imperium, electronic computatrum imperium progressio. In periculo areas et underwater res, compositum ex electronic computatrum imperium recipientis et laser ductu, ut animadverto in integrum automation of CAVATOR operatio. Omnia haec plenus hydraulicis pressura ex CAVATOR posuit fundamenta et creavit bonum praemissa.
III. Affigere momenti ad adoption of New Technologies, novum processus et novum structurae, et accelerate progressionem celeritate standardization, serialization et general. Exempli gratia, in EXCVATOR producitur per Atlas instructa cum nova engine celeritas regulanting fabrica ad sectam operating celeritate, et novus C series LC-(V) DCCC hydraulicorum CAVATOR est installed cum automatic imperium hydraulicarum, quod potest statim adjust in potestate. Et caps (computatrum, adiuvit potentia ratio) est etiam installed, amplio operating potestate ex CAVATOR, magis ad plenam ludere ad munus de hydraulica ratio; Quinque Novum exempla exempla excavators produci per sumitomo Iaponia instructa cum computer-adiuvat, potestate imperium system coniuncta ad Hydraulicarum Circuit, utendo denique-potestate, et hydraulicis ratio, reductionem et extendunt in ministerium vitae; Et oleum sentinam regulating ratio ex CAVATOR produci per OGAKAI (O & K) habet Confluentes characteres, ut oleum sentinam habere maximum opus efficientiam; Using the intelligentes Imperium ratio in Novum 904.905.907.909 Type Hydraulicorum CAVATOR, etiam imperitos coegi potest praestare complexiones; Liebherr, Germania developed in Eco (electronic imperium res), in operationem perficientur ex CAVATOR potest adaequatum secundum operationem requiruntur, effectus excelsum efficientiam et humilis cibus consummatio est effectum; In Nova B System CAVATOR, usura the latest 3114t genus Diesel engine, torque onus sensu pressura ratio, potentia modus electrix, etc., ulterius ad operationem efficientiam et stabilitatem in excavator. Doosan construction machinery company in DH 280 excavator adopted EPOS —— electronic power optimization system, according to the change of the engine load, automatically adjust the power absorbed by the hydraulic pump, make the engine speed always keep near the rated speed, namely the engine always with full power operation, both make full use of the engine power, improve the efficiency of the excavator, and prevent the engine due to overload.
IV. Update consilium doctrina ad amplio reliability et extend in ministerium vitae. America, Britain, Japan and other countries using limited life design theory, to replace the traditional infinite life design theory and method, and the fatigue damage accumulation theory, fracture mechanics, finite element method, optimization design, computer control of electrohydraulic servo fatigue test technology, fatigue strength analysis method and other advanced technology applied to the strength of hydraulic excavator research, promote the high quality product efficiency and aemulationes. Civitatibus Foederatis Americae posuit deinceps dynamic design analysis modum perpendendis dynamic fortitudinem et statutum doctrina praedicendi productum defectum et update. Iaponia habet developed in fortitudinem iudicium procedure of Hydraulicorum CAVATOR components et developed reliability notitia processus ratio. Sub ductu de supra basic doctrina, cum ope a numerus of probat, in investigationis cycle of novus products breviabuntur, upgrading processus of Hydraulica CAVATOR est accelerato, et reliability et diuturnitatem sunt melius. Exempli gratia, in operatio rate de hydraulicorum excavator pervenit LXXXV% ~ XCV%, et ministerium vitae plus quam 10,000 horas.
V. Confirma labore tutela ad coegi et amplio eorum operationem conditionibus. Hydraulicorum CAVATOR adoptat CAB cum procidens praesidio structuram et tipping tutela structuram, instadjustable flexibile sedem reduces strepitus intercessiones cum sonus velit.
VI. Praeterea amplio hydrau ratio. Et hydrau ratio medii et parvum hydraulicorum excavator habet obvious trend ad variabilis ratio. Quia variabilis ratio in processus olei pump, impressionem reducitur per augendae fluxus, ita ut potentia ad hydraulica sentinam manet constant, id est, et hydraulicarum pumped in varia et olei sentinam potest plenam usum maximam potestatem sentinam potest plenam usum maximam potestatem sentinam sentinam. Cum externa resistentia auget, reducere fluxus (reducitur celeritate) et excavation vis multiplicatur; Usus tres loop hydrau ratio. Ad producendum tres independens opus motibus. Ad consequi potestatem matching cum gyratorius mechanism. Tertium sentinam connexa ad alias motus ad secundum independens ieiunium motus aperto loop. In addition, Hydraulic technology est late in excavators, quae creates condiciones ad applicationem et promotionem electronic technology et automatic imperium technology in excavators.
VII. Cursim expand applicationem electronic et automation technology in excavators. In 1970s, ut salvum facere industria consummatio et reducere environmental pollutio, ut operationem ex CAVATOR lux et tutum, reducere vocem excavator, amplio operantes conditionibus coegi, electronic et automatic imperium technology est paulatim in excavationi. Cum emendationem ex CAVATOR opus efficientiam, industria salute et environmental tutela, lux operatio, salus et comfortable, certa et differentia et alias facies et electrica liquidum integration in cæcus et faciet in variis perficientur habet in specula et facite et in electum habet in eleemosum et faciet in electum. In 1980s, in microelectronics technology sicut core de excelsis et novi technology, praesertim microcomputer, micavator, sensorem et deprehensio instrumentum applicationem in CAVATOR Application et Promotionem, et Factus Mining System, Power System, Mode Mode System, Cras System, Mode et alia electronic imperium ratio.
