如果您面對的建筑或維護項目需要您進行高空作業(yè)，那么您將需要高度提升。根據(jù)您的工作地點和工作性質(zhì)，可能需要考慮臂式高空作業(yè)平臺或剪式高空作業(yè)平臺。

If you’re facing construction or maintenance projects that require you to work above ground level, you’ll need a boost. Depending on your worksite and the nature of your job, you may want to consider a boom lift or a scissor lift.

臂式升降機可以水平和垂直移動，而剪式升降機只能上下移動。雖然動臂式升降機具有更大的垂直范圍，但剪式升降機具有更大的平臺和更高的承重能力，使其能夠承載多人和貨物。

Boom lifts move horizontally and vertically, whereas scissor lifts can only move up and down. While boom lifts attain a greater vertical reach, scissor lifts have larger platforms with higher weight capacities, enabling them to carry multiple people along with loads of material.

下面，我們會解釋臂式高空作業(yè)平臺和剪式高空作業(yè)平臺之間的主要區(qū)別。

We’ll explain the main differences between boom lifts and scissor lifts to help you choose the right equipment for your next project.

臂式高空作業(yè)平臺是一種升降設(shè)備，可將通過載人籃筐或緊湊型升降工作平臺提升工人作業(yè)高度。這種類型的高空作業(yè)平臺具有接地底座和液壓升降系統(tǒng)。

A boom lift is a piece of lift equipment that elevates a worker in a small bucket or on a compact elevating work platform. This type of aerial lift features a grounded base and hydraulic lift system.

零排放電動臂式高空作業(yè)平臺可在室內(nèi)或室外使用，而柴油或雙燃料臂式高空作業(yè)平臺則設(shè)計用于室外。電動升降機的高度可以從8米延伸到30米，而柴油驅(qū)動的升降機可以從8米一直延伸到64米。它們的液壓臂具有更大的機動性，有些型號可以 360 度旋轉(zhuǎn)。

Zero-emission electric boom lifts can be used indoors or outdoors, while diesel or dual-fuel boom lifts are designed for outdoor use. Electric lifts can extend from 30 to 60 feet high, while diesel-powered lifts can go from 30 feet all the way up to 210 feet. Their hydraulic arm allows for greater maneuverability, and some models can rotate 360 degrees.

以下是選購臂式高空作業(yè)平臺的一些優(yōu)點和缺點：

Here are some pros and cons to choosing a boom lift for your construction or maintenance project:

優(yōu)點

Pros

• 可以延伸到很大的舉升高度。

• 重量輕且狹窄，適合在狹窄區(qū)域使用。

• 機動性極強。

• 適用于各種項目，包括：

• 管道工作。

• 外部清潔。

• 維修項目。

• Can extend to great lift heights.

• Highly maneuverable.

• Lightweight and narrow for use in tight areas.

• Good for a variety of projects including：

• Piping work.

• Exterior cleaning.

• Maintenance projects.

缺點

Cons  

• 較小的平臺或籃筐限制了它的承載能力。
  

• 平臺通常只能容納一名工人。
  

• 通常比剪刀式升降機的價格更貴。

• Smaller platforms or buckets limit how much it can carry.

• Platforms typically have room for just one worker.

• Typically more expensive to rent than a scissor lift.
  

這些升降機（也稱為載人升降機、空中升降機或櫻桃采摘機）主要分為三種類型：曲臂式升降機、直臂式升降機和車載臂式升降機。

These lifts — also known as man lifts, aerial lifts, or cherry pickers — come in three primary varieties: articulating boom lifts, telescopic boom lifts, and bucket trucks.

曲臂式高空作業(yè)平臺— 節(jié)臂使這些升降機能夠繞過拐角和障礙物（例如外墻）彎曲。當(dāng)在擁擠的倉庫中存取物品或繞過外部工作場所障礙物時，非常方便。

Articulating boom lift — The “knuckled” arms allow for these lifts to bend around corners and obstacles, such as exterior walls. This can be useful when accessing items in crowded warehouses or in moving around exterior worksite obstacles.

直臂式高空作業(yè)平臺— 它們沒有曲臂式高空作業(yè)平臺的接頭，而是配備了伸縮的直臂。這些可用于需要長距離的橋梁工程等項目，或可能需要更高高度的高層建筑的維護工作。

Telescopic boom lifts — These lack the joints of an articulating boom lift and are instead equipped with straight arms that expand or contract like a telescope. These can be used for projects such as bridge work, where a long reach is needed, or for maintenance work on highrises, which may require greater height.

車載臂式高空作業(yè)平臺— 這種類型的升降機是附有液壓起重機的車載式高空作業(yè)平臺；它通常用于樹木修剪和公用設(shè)施線路。它們也被稱為櫻桃采摘機，因為它們經(jīng)常用于果園工作，但它們也可以用來修剪桉樹和棕櫚樹等高大的樹木。

Bucket truck — This type of lift is a truck-mounted aerial platform attached to a hydraulic crane; it’s often used to access trees and utility lines. They’re also known as cherry pickers because they’re often used for orchard work, but they can also be used to prune tall trees like eucalyptus and palms.

剪叉式升降機是一種具有大型、平坦的工作臺面的設(shè)備，該平臺由多組剪叉臂架支撐。這些支架擠壓在一起，將平臺向上推。剪叉式升降機需要置于工作區(qū)旁邊平坦、結(jié)實的地面上，以便升降機上的人員能夠安全施工。

A scissor lift is a piece of equipment with a large, flat aerial work platform supported by a series of crisscrossed braces. These braces squeeze together to push the platform upward. The base of the scissor lift needs to sit on flat, stable ground directly beside the workspace for the project to be accessible to those on the lift.

剪式升降機可以在垂直方向上從3米延伸到14米的高。設(shè)備有電動版，可在室內(nèi)使用，垂直升降，非常適合堆放或拿取貨物。它們還有四輪驅(qū)動、越野型號，可以在不平坦的室外地面區(qū)域行駛。

Scissor lifts can extend from 10 feet up to 60 feet high in a straight vertical direction. They’re available in electric versions that can be used indoors and are ideal for providing vertical access so you can stack or unload inventory. They also come in four-wheel-drive, rough-terrain models that can navigate uneven outdoor ground areas.

• 必須直接放置在工作區(qū)域附近，才能準(zhǔn)確抵達作業(yè)點。

• Cannot reach as high as the greatest heights reached by a boom lift.

• Not as maneuverable as a boom lift.

• Must be placed directly adjacent to the work area for best access.

根據(jù)其用途和供電方式，剪式升降機有多種變體。

Scissor lifts come in a number of variations, based on their intended use and how they’re powered.

在考慮租用哪種升降機時，需要評估您正在做什么類型的工作、在哪里工作、需要多少人力以及您的預(yù)算。無論您是選擇臂式升降機還是剪式升降機，不同類型的升降機的價格都有很大差異。

When thinking about what kind of lift to rent, take stock of what kind of job you’re doing, where you’re doing it, how much power you need, and your budget. There’s a big range in the price for renting different types of lifts, whether you’re looking at boom lifts or scissor lifts.

選購時，您可以考慮以下幾個因素：

Here are a few factors you can consider:

【1】需要升到多高？

【1】How high do you need to go? 

一般來說，臂式升降機可以讓您進入更高的區(qū)域，而剪叉式升降機可能是高達16米的區(qū)域的不錯選擇，具體取決于工作的區(qū)域。

Boom lifts, in general, can give you access to areas that are higher up, while scissor lifts can be a good choice for areas up to 50 feet high, depending on the area where you’re working.

【2】施工方向是什么？

【2】What direction do you need to move in?

如果您只需要垂直升降，剪叉式升降機可能是一個不錯的選擇。

 If you need to go straight up and down, a scissor lift could be a good choice.

【3】有多少工人參與其中？

【3】How many workers are involved?

臂式升降機提升鏟斗的空間有限，通?？扇菁{單個工人。剪叉式升降機通?？梢匀菁{更多的工人，并且具有更高的重量限制。

Boom lift buckets have limited space and typically accommodate single workers. Scissor lifts can often accommodate more workers and have a higher weight limit.

【4】工地地形如何？

【4】What is the jobsite terrain?

崎嶇地形剪式高空作業(yè)平臺和臂式高空作業(yè)平臺由柴油驅(qū)動，在不平坦或巖石地形上非常有效。

Rough terrain scissor lifts and boom lifts, powered by diesel fuel, can be effective on uneven or rocky terrain.

【5】您的預(yù)算是多少？

【5】What is your budget?

臂式升降機的價格從5萬~100萬不等，具體取決于它們的大小和功能。剪式升降機通常更便宜，1萬~10萬不等。

Boom lifts can range in price from RMB 50,000 to RMB 1,000,000, depending on how big they are and what they can do. Scissor lifts are generally cheaper, ranging from RMB 10,000 to RMB 100,000.
