            Perform to Your Standards 按照標準操作

            Your excavator needs to get the job done, and that’s the top criteria when choosing the right excavator. To make sure you’ve got enough power for your operation, look at the hydraulic systems and testing options for your next excavator. Many will list the power of their system and note what work can be performed during a full workday thanks to that power.您的挖掘機需要完成工作,而這是選擇正確的挖掘機的首要條件。 為了確保您有足夠的動力進行操作,請查看下一臺挖掘機的液壓系統和測試選項。 許多人將列出其系統的功能,并指出由于該功能可以在一個工作日內完成哪些工作。

            More powerful hydraulic systems allow for improvements in your efficiency and productivity because you’re matching the power you need, but performance also includes the best support for your job. Consider all of the jobs your excavator will need to perform when making your choice.強大的液壓系統可以滿足您所需的動力,因此可以提高效率和生產率,但是性能還包括對工作的最佳支持。 在做出選擇時,請考慮您的挖掘機將需要執行的所有工作。

            Two major support options to consider are zero tail swing or zero house swing features for your excavator. These configurations allow your operator to work close to dig sites, walls and other obstacles in a safe manner.要考慮的兩個主要支持選項是挖掘機的零尾擺角或零房屋擺角功能。 這些配置使您的操作員可以安全地在挖掘現場,墻壁和其他障礙物附近工作。

            The zero-swing for the tail allows an excavator to move nimbly and reduces the likelihood of any accidental impact with a surrounding object, building or machine. During a turn, the zero-swing for housing helps prevent your operator from hitting the front and sides of the excavator when moving.尾部的零擺角使挖掘機可以靈活移動,并減少了對周圍物體,建筑物或機器的意外撞擊的可能性。 轉彎時,機殼的零擺有助于防止操作員在移動時碰到挖掘機的正面和側面。

            Zero-swing options are smart if you’re working in a space with a lot of obstacles on either side. However, this configuration means a wider excavator, and that isn’t always suitable for a worksite.如果您在兩邊都有很多障礙物的空間中工作,則零擺選項是明智的選擇。 但是,這種配置意味著挖掘機更寬,并不總是適合于工作現場。

            Almost all excavators have an advantage over the traditional backhoe: the boom is independent. This allows your operator to manage the machine and create a stable base that needs to be moved less. You’re getting better visibility and power with smoother operations.幾乎所有挖掘機都比傳統的反鏟挖掘機更具優勢:動臂是獨立的。 這使您的操作員可以管理機器并創建需要減少移動的穩定基座。 通過更順暢的操作,您可以獲得更好的可見性和功能。


            Match It to Your Site 找出合適的大小

            What does your job site look like? Picture it, including the hazards and your current needs, plus those you expect as your project moves through each phase. The best way to make sure you’re covered with your excavator purchase is to imagine all of your possible needs.您的工作地點是什么樣的? 對其進行構想,包括危害和當前需求,以及項目在每個階段進行中所期望的需求。 確保對您的挖掘機的購買感到滿意的最好方法是想象所有可能的需求。

            If you’re running a big operation or need equipment for the long haul, it’s best to judge the excavator based on your typical jobsite. Different models perform better on large, flat landscapes, compared to urban environments where there are many buildings and obstacles nearby.如果您要進行大型作業或需要長途運輸的設備,則最好根據您的典型工作地點來判斷挖掘機。 相較于附近有許多建筑物和障礙物的城市環境,不同的模型在大而平坦的景觀上表現更好。

            After you consider your location, think about the jobs performed on your average site. The right excavator for your company must be able to perform your common reach, dig, lifting, carrying and other functions. Review past jobs and take proper measurements, such as loads or how deep your digs were.在考慮了您的位置之后,請考慮一下您在普通站點上執行的工作。 適合您公司的挖掘機必須能夠執行常見的伸手,挖掘,提升,搬運和其他功能。 回顧過去的工作并進行適當的測量,例如載荷或挖掘的深度。

            Consider the following top specifications to match an excavator to your job:參考如下因素:

            • Engine power. You need an engine strong enough to get around your jobsite and perform tasks. When digging deep into specifications, include the bore and piston stroke so you can compare the strength of different engines.發動機功率。 您需要一個足夠強大的引擎來繞過工作現場并執行任務。 在深入研究規格時,請包括缸徑和活塞沖程,以便您可以比較不同發動機的強度。

            • Weight. Focus on the maximum operating weight, which will cover the equipment, operator and load options. You don’t want an excavator that’s too heavy and will damage your site.重量。 著重于最大操作重量,該重量將涵蓋設備,操作員和負載選項。 您不希望使用太重的挖掘機,否則會損壞您的站點。

            • Size. Make sure your excavator can fit in your site. Typically excavators are sized based on tonnage, corresponding to their operating weight. As tonnage goes up, breakout force goes up proportionally.尺寸。 確保您的挖掘機適合您的現場。 通常,挖掘機是根據噸位確定尺寸的,相應于其工作重量。 隨著噸位的增加,突圍力成比例地增加。

            • Bucket capacity. Because buckets are among the most common use for excavators, check the types of buckets it supports and the maximum capacity of the bucket option.鏟斗容量。 由于鏟斗是挖掘機最常用的工具之一,因此請檢查其支持的鏟斗類型以及鏟斗選件的最大容量。

            圖片關鍵詞

            Size Matters

            size matters when choosing an excavator

            While you’re thinking about your job standards and the common jobsite you work with, start the process of narrowing your search. Begin with reviewing the size and type of excavators. Remember that categories are general and specifications may differ by manufacturer, so get your mind set on a size —such as 5 tons —instead of a “mini.” Consider the following top types of excavators:在考慮自己的工作標準和共同的工作場所時,請開始縮小搜索范圍。 首先檢查挖掘機的尺寸和類型。 請記住,類別是通用的,規格因制造商而異,因此請確定大?。ɡ?噸)而不是“迷你”。 考慮以下幾種頂級挖掘機:

            • Mini or compact. These small excavators are typically the most mobile. They can weigh from as low as 2,100 pounds to just under 10 tons. A mini is a top choice for small jobs and those with tight space requirements, such as those that require the ability to maneuver around a building or work in areas with many lines running through the ground. These require the least amount of power, but they’ll also do the least amount of damage to the yard, road and sidewalk.迷你或緊湊。 這些小型挖掘機通常移動性最強。 它們的重量從低至2100磅到不到10噸。 小型機是小型工作和空間狹窄的工作的最佳選擇,例如那些需要在建筑物周圍機動或在多條穿過地面的區域工作的能力的工作。 它們所需的電力最少,但對院子,道路和人行道的破壞也最少。

            • Standard. Excavators that are larger than 10 tons and below 45 tons fall into the standard designation. These are the most versatile excavators, working well in just about any space and with most types of jobs. They come with a lot of power, so it’ll be heavy and do a little damage to the land it has to cross. You’ll need plenty of space, but they’re strong and easy to transport. They’re common in the construction space.標準。 大于10噸且小于45噸的挖掘機屬于標準名稱。 這些是用途最廣泛的挖掘機,幾乎可以在任何空間和大多數類型的工作中工作。 它們具有強大的動力,因此很沉重,并且對它要穿越的土地造成了一點損害。 您需要足夠的空間,但它們堅固且易于運輸。 它們在建筑空間中很常見。

            • Large. Excavators can reach up to 95 tons, and these behemoths fall into the large category. These machines are pure industrial workhorses. You won’t see them in urban environments or those with a lot of slopes around the work site, but they constantly provide power for major construction. These machines will require a significant investment in the equipment and trailer to move them to each job site. If you need this size and power, you’ll know it.大型。 挖掘機的重量可達95噸,這些龐然大物屬于大類。 這些機器是純工業動力。 您不會在城市環境中或在工作場所周圍有很多斜坡的地方看到它們,但是它們不斷為大型建筑提供動力。 這些機器將需要大量的設備和拖車投資,以將它們移動到每個作業現場。 如果您需要這種尺寸和功能,就會知道。

            • There are many different configurations available in each segment. Modern designs now allow standard and mini excavators to be more versatile for a variety of work situations. These include the options for the undercarriage to retract and let an excavator move through narrow areas such as fence gates, and then expand when they need a solid base to perform the work.每個網段中都有許多不同的配置。 現在,現代設計使標準和小型挖掘機在各種工況下具有更多用途。 這些選項包括使底盤縮回并讓挖掘機在狹窄的區域(例如柵欄門)中移動,然后在需要堅固的底座進行工作時擴展的選項。

            • Why Use a Mini Excavator? 為何選擇小型挖掘機?

            • While some applications require the power of a standard or large excavator, power isn’t everything when it comes to certain jobs. Mini excavators offer several advantages over their larger counterparts, including:盡管某些應用需要使用標準或大型挖掘機的力量,但對于某些工作而言,動力并不是萬能的。 小型挖掘機比大型挖掘機具有多個優勢,包括:

            • Less impact. Because they are smaller and lighter, mini excavators leave reduced track marks and cause less ground damage.影響較小。 小型挖掘機體積更小,重量更輕,因此它們留下的履帶痕跡減少,對地面的損害也較小。

            • Smaller footprint. Compact mini excavators are easier to work with when a work site is small or crowded, like a parking lot.占地面積小。 小型微型挖掘機在工作場所較小或擁擠的地方(例如停車場)更易于使用。

            • Easy transport. Mini excavators can be loaded onto the back of a utility truck or relatively small trailer for simple transfer between job sites.方便運輸。 小型挖掘機可以裝載到多用途卡車或相對較小的拖車的背面,以便在作業現場之間輕松轉移。

            • Low transportation weight. Several Cat mini excavator models have an operating weight of less than 10,000 lbs., which means you may be able to trailer and tow a mini excavator with a standard Class C California driver’s license.運輸重量輕。 某些Cat小型挖掘機的工作重量小于10,000磅。這意味著您可以拖車和拖曳具有標準C級加利福尼亞駕駛執照的小型挖掘機。

            • Mini excavators are ideal for jobs that take place within a tight area. Working in a backyard, for example, involves having to maneuver through gates and around a small space. A mini excavator can perform the same functions a standard excavator can, but it does so on a smaller scale. This can significantly speed up jobs where digging would otherwise have to be done manually.小型挖掘機是狹窄區域內作業的理想選擇。 例如,在后院工作涉及到必須穿過大門并圍繞狹小的空間進行機動。 小型挖掘機可以執行與標準挖掘機相同的功能,但是規模較小。 這可以顯著加快原本必須手動進行挖掘的工作。

            • When to Use a Mini Excavator 何時使用?

            • What is a mini excavator good for? Mini excavators have a variety of possible attachments that make them highly versatile. With their light frame and compact size, there are more uses for mini excavators than you might expect. Here are four examples of jobs where this type of machine is a good option.小型挖掘機有什么用? 小型挖掘機具有多種可能的附件,因此具有很高的通用性。 憑借其輕巧的機身和緊湊的尺寸,微型挖掘機的用途超出了您的預期。 這是此類機器的不錯選擇,下面是四個作業示例。

            • 1. Utility Line Install or Repair

            • An excavator is a great tool for digging trenches for line install or replacement. When digging with the excavator you are looking right in the trench that you are looking to dig, where digging with a trencher you are trenching behind you. Also you are able to place your spoil where you need it vs the side of the trench where you might have to use another tractor to move it.

            • 1.公用線的安裝或維修

            • 挖掘機是挖溝的好工具,用于管道的安裝或更換。 當使用挖掘機進行挖掘時,您正要在要挖掘的溝槽中看,而使用挖溝機進行挖掘則是在您的后方挖溝。 此外,您還可以將戰利品放置在需要的地方,而戰trench的側面則可能需要使用其他拖拉機移動它。

            • 2. Excavation

            • When needing to dig out an area the excavator can be the perfect tool. With the excavator you can swing the machine 360 degrees so you can dump the material where you want it. Pool Excavation, landscaping & building pad excavation is almost completely performed by excavators. Another advantage with excavators is when you need to over-excavate a pad for compaction you can easily meter in the material to the desired thickness for proper compaction. Also another great application for the excavator is digging footings for retaining walls or buildings.

            • 2.開挖

            • 當需要挖掘區域時,挖掘機可以是理想的工具。 使用挖掘機,您可以將機器旋轉360度,以便將物料倒入所需的位置。 泳池開挖,園林綠化和建筑基坑開挖幾乎完全由挖掘機完成。 挖掘機的另一個優點是,當您需要過度挖掘墊板進行壓實時,您可以輕松地將材料計量到所需的厚度,以進行正確的壓實。 挖掘機的另一個重要應用是為擋土墻或建筑物挖掘基礎。

            • 3. Demolition

            • If you are removing a concrete patio or a structure a mini excavator can be very handy. You can have the machine equipped with a hydraulic thumb to hold the debris while tearing them out & loading the truck or trailer to take them away. You can also add a hydraulic hammer or breaker to bust up concrete slabs or rocks.

            • 3.拆除

            • 如果您要拆除混凝土天井或結構,則小型挖掘機非常方便。 您可以讓機器配備液壓拇指,以便在將碎片撕裂并裝載卡車或拖車以將其帶走時握住碎片。 您也可以添加液壓錘或破碎錘來破壞混凝土板或巖石。

            • 4. Drilling Holes

            • The mini excavator’s ability to maneuver in tight spaces makes it an essential tool on job sites where you need to drill holes in multiple awkward areas. Using a mini excavator means workers don’t have to resort to manual shoveling or using other hand tools to drill the holes. Also with the mini excavator you can reach over obstacles & drill at almost any angle. Since the auger is hydraulic driven where ever the end of the excavator stick is you can drill a hole.

            • 4.鉆孔

            • 這款小型挖掘機具有在狹窄空間內機動的能力,使其成為需要在多個笨拙區域鉆孔的作業現場的必不可少的工具。 使用小型挖掘機意味著工人不必求助于手動鏟土或使用其他手動工具鉆孔。 此外,使用小型挖掘機,您可以越過障礙物并以幾乎任何角度進行鉆孔。 由于螺旋鉆是液壓驅動的,因此在挖掘機斗桿的末端都可以鉆一個孔。

            • Operator Comfort Is Important 舒適很重要

            • Selecting the right excavator involves matching the excavator to your needs. This should also include pairing the right excavator with your operators.選擇合適的挖掘機需要將挖掘機與您的需求進行匹配。 這還應包括將正確的挖掘機與操作員配對。

            • Many models are focused on the comfort of the operator through the use of ergonomic chairs and controls. Look for a cab that has plenty of room and allows for easy access to all of the controls and features of the excavator. Adjustable seats with lateral movements allow your operator to work comfortably, providing enough flexibility to quickly accommodate different operators.通過使用符合人體工學原理的座椅和控制裝置,許多型號都將重點放在操作員的舒適度上。 尋找具有足夠空間的駕駛室,該駕駛室可輕松使用挖掘機的所有控件和功能。 帶有橫向運動的可調節座椅使您的操作員舒適地工作,并提供足夠的靈活性以快速適應不同的操作員。

            • Part of the comfort equation for how to choose an excavator should also include a heating and air conditioning system. These need to be powerful enough to maintain comfort in your region. Many new cabs offer controls similar to those in cars and trucks. Take a peek at these and make sure the controls are easy to understand. Look for two vents: one in front of and one behind the operator’s seat.有關如何選擇挖掘機的舒適方程式的一部分,還應包括供暖和空調系統。 這些功能必須足夠強大,以保持您所在區域的舒適度。 許多新的出租車都提供與轎車和卡車類似的控件。 快看一下這些內容,并確??丶子诶斫?。 尋找兩個通風口:一個在操作員座椅的前面,另一個在操作員座椅的后面。

            • The longer your operators will need to use the excavator in a single sitting, the more comfort should play a role in your selection. When wondering how to buy an excavator, choose one that will help maintain performance instead of work against it.您的操作員需要一次坐下使用挖掘機的時間越長,選擇舒適性就越重要。 在想知道如何購買挖掘機時,請選擇一種有助于維持性能而不是對其造成不利影響的挖掘機。

            • The Right Tools for the Job 最佳工具

            • other important tools beside an excavator

            • Choosing an excavator changes when you’re looking to work beyond digging. If you need a versatile machine, it’s time to consider the attachments that it supports. Excavators can be expanded with a wide range of support equipment for different jobs, and some of the most common are as follows:當您要進行挖掘以外的工作時,選擇挖掘機會發生變化。 如果您需要一臺多功能的機器,那么該考慮一下它所支持的附件了。 挖掘機可以使用各種支持設備進行擴展,以完成不同的工作,其中一些最常見的情況如下:

            • Buckets. Buckets are the most versatile extension of your excavator, with a variety of different styles for digging, grading, ditch cleaning and more, with options to match to the severity of your workload.桶。 鏟斗是挖掘機最通用的擴展件,具有多種不同的挖掘,平地,溝渠清潔樣式以及更多選擇,可以根據您的工作量的嚴重性進行選擇。

            • Couplers. These attachments allow your excavator to quickly switch tools without needing a crew. This means your machine can move between multiple tasks as you move about the job site.耦合器。 這些附件使您的挖掘機無需人員即可快速切換工具。 這意味著您在工作現場中移動時,機器可以在多個任務之間移動。

            • Compaction. Both compaction wheels and vibratory plates and useful for pipeline contractors and site preparation.壓實。 壓實輪和振動板均可用于管道承包商和現場準備。

            • Rippers. Break up hard soil or even ice on the ground with a ripper. These are common for trenching and pipeline support, with options to support couplers and a variety of different depths.開膛手。 用裂土器將硬土或什至在地面上的冰打破。 這些在挖溝和管道支撐中很常見,可以選擇以支撐耦合器和各種不同的深度。

            • Hammers. Excavators are commonly used in demolition, taking down buildings and pavement. Hammers make quicker work of this effort, particularly being able to swap between the tool and a bucket with the use of a coupler.挖掘機通常用于拆除,拆除建筑物和人行道。 錘子可以使這項工作更快地完成,特別是能夠通過使用聯接器在工具和鏟斗之間互換。

            You’ll typically match your excavator with attachments from the same manufacturer. This is a good idea because it’ll help with warranties. It also ensures that your attachment functions properly with the unique mounting system of your excavator. It’s especially important to match equipment and your excavator when you use a hydraulic actuated system because it manages your attachment changes with the simple push of a cab button.通常,您會將挖掘機與同一制造商的附件相匹配。 這是個好主意,因為它將有助于保修。 它還可以確保您的附件通過挖掘機獨特的安裝系統正常運行。 使用液壓驅動系統時,將設備與挖掘機匹配尤其重要,因為它只需按下駕駛室按鈕即可管理附件的更換。

            Additional Features for Selecting the Right Excavator選擇合適的挖掘機的其他功能

            There are some secondary features you should also consider when you’re finalizing your excavator purchase. These can help you choose the right excavator by providing you with a checklist to compare your top options.完成挖掘機的購買時,還應考慮一些輔助功能。 通過為您提供清單以比較您的最佳選擇,這些可以幫助您選擇合適的挖掘機。

            Some of the more important secondary features include the following:

            • Anti-vandalism features. These options include the ability to lock different parts and locations on the machine so it cannot be used and nothing can be removed. These are useful if you need to leave your excavator on-site. This allows you to protect your equipment and jobsite, while giving you a shield against liability for anyone injured after sneaking onto your site.防破壞功能。 這些選項包括鎖定機器上不同零件和位置的功能,這樣就無法使用它,并且什么也不能刪除。 如果您需要將挖掘機留在現場,這些功能將非常有用。 這可以保護您的設備和工作場所,同時還為您提供了保護,使您不必再為潛入您網站后受傷的任何人承擔責任。

            • Power modes. Different power distribution modes include power options for your attachments and boom. Some will also include a way to provide extra power to your tracks. These systems allow you to increase performance in common situations that your equipment will face.電源模式。 不同的配電模式包括附件和吊桿的配電選項。 有些還包括一種為軌道提供額外動力的方法。 這些系統使您可以在設備將要面對的常見情況下提高性能。

            • Hydraulic controls. Newer excavators have introduced top-of-the-line hydraulics into the cab to help improve control. It allows your operator to be precise with movements and makes overall operation easier. Ergonomic setups will also make the performance more comfortable for your operator.液壓控制。 較新的挖掘機已在駕駛室中引入了頂級液壓系統,以幫助改善控制能力。 它使您的操作員可以精確地移動,并使整體操作更加輕松。 符合人體工程學的設置還將使您的操作員感到更舒適。

            hese considerations are very important when you’re focusing on how to buy an excavator.

            Before Choosing an Excavator 購買指南

            Before you choose checklist


            When reviewing your potential excavator, be sure to check the following: 當考慮心中意向時,請參考以下要點

            • Observe how it starts up. It’s better for the engine to start right away and not need time to pull from the battery.觀察它是如何啟動的。 最好立即啟動引擎,而不需要時間從電池中拔出。

            • Check for any leaks or smoke. While some water may leak from an AC system and engines can produce a small amount of smoke, always check to see if these are within the norm for the machine. Check any fluid leak and make sure it’s not a vital system.檢查是否有泄漏或冒煙。 盡管有些水可能會從交流系統漏出,并且發動機會產生少量煙霧,但始終要檢查一下是否在機器的正常范圍內。 檢查是否有液體泄漏,并確保它不是至關重要的系統。

            • Review the condition of the oil and other fluids of the machine. These should be fresh, but it may be a warning sign if someone is trying to sell you a machine with old hydraulic or other oils.檢查機器的機油和其他流體的狀況。 這些應該是新鮮的,但是如果有人試圖向您出售帶有舊液壓油或其他油的機器,則可能是一個警告信號。

            • Open it up and quickly look at the engine and wiring. You want everything to look like it’s in good shape and you want the wiring to look professional. Electrical tape throughout can be a warning sign.打開它,然后快速查看引擎和接線。 您希望一切看起來都很好,并且您的接線看起來也很專業。 整個電工膠帶可能是一個警告信號。

            • Test the features and equipment. For example, you can review slew ring wear by lifting the boom and moving the body by hand. A little play in the swivel mechanism is okay for swivel booms, so you’re looking for excessive movement or apparent wear when you do move it.測試功能部件和設備。 例如,您可以通過抬起吊桿并用手移動主體來檢查回轉支承的磨損情況。 擺臂可以稍稍擺動一下,所以擺臂運動時會出現過度運動或明顯磨損的情況。

            A thorough check can save you a lot of headaches, repairs and money. Plus, it helps you keep your workers safe, and that’s the biggest benefit of all.全面檢查可以為您省去很多頭痛,維修和金錢。 另外,它可以幫助您確保工人的安全,這是最大的好處。
