\"The<\/p>\n

Heavy machinery plays a major role at demolition and construction sites. Although we refer to it simply as \u201cheavy machinery,\u201d there are actually many different types. There are also several different names for them, and many people may find these differences confusing.<\/p>\n

In this article, we\u2019ll explain the different types of heavy equipment, their characteristics, how to choose the right one, and the licenses required to operate them.<\/p>\n

What is heavy equipment?<\/h2>\n

\"The<\/p>\n

\"Heavy machinery\" refers to powered machinery used at construction sites that is operated by one or two people. It is used for tasks such as excavation, various types of material delivery, snow removal, transportation, material removal, and demolition.<\/p>\n

Because they are powered by engines, they can perform tasks many times faster than humans can. Although they are sometimes confused with \u201cconstruction machinery,\u201d the distinction is actually vague.<\/p>\n

In this section, we\u2019ll introduce the names and uses of heavy machinery.<\/p>\n

The Difference Between Heavy Equipment and Excavators<\/h3>\n

You often hear the term \u201cYunbo.\u201d A Yunbo is one of many types of heavy machinery, and its official name is \u201chydraulic excavator.\u201d It is also known as a power shovel, backhoe, or excavator.<\/p>\n

Since they perform tasks such as \u201cdigging\u201d and \u201cexcavating\u201d\u2014which are common on construction sites\u2014they can be considered the workhorses of heavy equipment. Although they go by various names, there is no clear distinction between a \u201cyunbo\u201d and a \u201cpower shovel.\u201d Strictly speaking, \u201cyunbo\u201d and \u201cpower shovel\u201d are simply alternative names for a hydraulic excavator.<\/p>\n

Why is it called a \"yunbo\"?<\/h3>\n

Even though the official name is \u201chydraulic excavator,\u201d why is it often called a \u201cyumbo\u201d?<\/p>\n

The reason for this is the name of the first product introduced in Japan. The model manufactured using technology provided by the French company Sicam was named \u201cYumbo.\u201d<\/p>\n

As the name became widely known alongside this product called \u201cYumbo,\u201d the term \u201cYumbo\u201d became firmly established. Similarly, terms like \u201cpower shovel\u201d and \u201cshovel car\u201d also gained widespread recognition as product names, leading people to mistakenly believe they were model names.<\/p>\n

Uses of Heavy Equipment<\/h3>\n

Heavy equipment is used for a variety of purposes, including not only excavation and transportation but also lifting materials and grading land. The types of heavy equipment and their main uses are as follows.<\/p>\n\n\n\n\n\n\n\n\n
Model<\/td>\nUses<\/td>\n<\/tr>\n
Hydraulic Excavator<\/td>\nExcavation, Lifting, Demolition, Industrial Waste Sorting, and Site Grading<\/td>\n<\/tr>\n

Heavy Equipment Mechanisms and Attachments<\/h2>\n

\"The<\/p>\n

Heavy machinery is primarily powered by diesel engines. In recent years, environmentally friendly hybrid models have also appeared on the market.<\/p>\n

Heavy machinery uses hydraulics to lift materials that are too heavy for humans to handle. There is a wide variety of attachments available, and they can be swapped out. This combination of hydraulic power and a wide range of attachments is why heavy machinery can perform various tasks many times faster than humans.<\/p>\n

From here on, we\u2019ll take a closer look at the mechanisms of heavy machinery and the different types of attachments.<\/p>\n

The Three Mechanisms That Make Up Heavy Equipment<\/h3>\n

Heavy machinery, such as hydraulic excavators, is generally composed of three main components: the working mechanism, the upper rotating assembly, and the lower travel assembly.<\/p>\n

The upper rotating body is the part that operates the machine and houses the engine compartment and counterweight. This counterweight prevents the machine from tipping over.<\/p>\n

The undercarriage is the running gear of the heavy machinery. The left and right tracks can be moved independently, allowing the machine to not only move forward but also turn.<\/p>\n

The work arm is the part that actually performs the detailed work; in human terms, it is equivalent to the arm. Attachments are mounted on this part.<\/p>\n

Heavy Equipment Attachments<\/h3>\n

A key feature of heavy equipment is its ability to handle a wide variety of tasks using various attachments. The main attachments include the following:<\/p>\n\n\n\n\n\n\n\n\n\n\n
Attachment<\/td>\nFeatures<\/td>\n<\/tr>\n
Bucket (Shovel)<\/td>\nThis is a standard attachment used for excavating and loading soil and for grading. Some models feature a lattice-style bottom to allow for screening.<\/td>\n<\/tr>\n
Grapple (Fork)<\/td>\nIt can be used to lift materials by clamping them. It is used for demolition and sorting.<\/td>\n<\/tr>\n
Breaker<\/td>\nThis attachment delivers hammer-like blows to crush hard objects.<\/td>\n<\/tr>\n
Crusher<\/td>\nThis is an attachment that crushes materials by clamping them between its large claws.<\/td>\n<\/tr>\n
Cutter<\/td>\nThis is an attachment for cutting steel beams. It is used in demolition and scrap metal processing.<\/td>\n<\/tr>\n
Magnet<\/td>\nYou can use the force of a magnet to lift iron.<\/td>\n<\/tr>\n
Vibro Hammer<\/td>\nThis is an attachment used for driving piles. It is used for soil improvement and foundation work.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

In addition, there are attachments for mowing and forestry, as well as attachments for digging holes that come with a drill.<\/p>\n

Purchase of Heavy Equipment<\/h2>\n

\"The<\/p>\n

When purchasing heavy equipment, how should you go about choosing it? While there is a wide variety of heavy equipment available worldwide, Japanese-made models are particularly popular.<\/p>\n

The reason for its popularity is its high quality, which means it rarely breaks down and lasts a long time. This high quality also contributes to the large number of used items on the market.<\/p>\n

In the following section, we\u2019ll introduce heavy equipment manufacturers and their features, and explain in detail how to choose the right one from among them.<\/p>\n

Heavy Equipment Manufacturers and Their Features<\/h3>\n

With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here. I look forward to your continued support.","sameAs":["http:\/\/enta-d.co.jp\/","https:\/\/www.facebook.com\/norimenman\/","https:\/\/www.instagram.com\/enta.d\/","https:\/\/x.com\/norimenman","https:\/\/www.youtube.com\/c\/entadnorimenman"]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/norimen.net\/64179-2\/#local-main-organization-logo","url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","contentUrl":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","width":220,"height":50,"caption":"\u65b0\u30a8\u30f3\u30bf\u306e\u6cd5\u9762\u7ba1\u7406\u587e"}]}},"jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"publishpress_future_action":{"enabled":false,"date":"2026-08-21 13:55:40","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"jetpack_featured_media_url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2019\/07\/c80a122c15f814a1493f5fa1870f4671.png","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/48729","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/comments?post=48729"}],"version-history":[{"count":2,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/48729\/revisions"}],"predecessor-version":[{"id":60369,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/48729\/revisions\/60369"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/39421"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=48729"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=48729"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=48729"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
