Among many available options, the <strong>Hitachi KH230-3 crawler crane<\/strong> (1990 model) remains highly regarded thanks to its long-lasting durability, flexible operation, and powerful hydraulic system.<\/p>\n<p>This model is particularly suitable for contractors who require a 60-ton crane for projects on soft ground, with high demands for load-bearing capacity and continuous multi-shift operation. In addition, the Hitachi KH230-3 features an easy-to-assemble and disassemble configuration, making transportation and maintenance more convenient.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-6391\" src=\"https:\/\/mayxaydunghanoi.com\/wp-content\/uploads\/2025\/10\/cau-banh-xich-hitachi-kh230-3.jpg\" alt=\"Hitachi KH230-3 crawler crane, 1990 model\" width=\"800\" height=\"600\" \/><\/p>\n<p>In this article, Hanoi Vietnam will provide an in-depth analysis of the technical aspects, real-world performance, operating costs, and comparisons with other crane models to help engineers and investors make the right decision.<\/p>\n<hr \/>\n<h3>Main boom design and reliable lifting capacity<\/h3>\n<p>The Hitachi KH230-3 is equipped with a <strong>high-strength steel lattice boom<\/strong> measuring 1,400 \u00d7 1,400 mm, providing excellent stability when handling heavy loads. The base boom length is 13 m and can be extended with 3 m, 6 m, and 9 m sections, allowing a maximum boom length of <strong>34 m<\/strong>.<\/p>\n<p>Rated lifting capacities are calculated with multiple safety margins:<\/p>\n<ul>\n<li>Maximum lifting capacity of <strong>60 tons at a 3.7 m radius<\/strong>.<\/li>\n<li>When using an auxiliary jib, lifting capacity varies depending on jib length and offset angle.<\/li>\n<li>Lifting capacities are always calculated after deducting the weight of accessories such as hooks, buckets, or lifting frames.<\/li>\n<\/ul>\n<p>This allows engineers to accurately calculate and select suitable attachments for each lifting plan. Notably, the <strong>pin-connected boom sections<\/strong> enable quick on-site assembly, saving valuable construction time.<\/p>\n<hr \/>\n<h3>Auxiliary boom and jib: Flexible support for lighter loads<\/h3>\n<p>One of the key advantages of the <strong>Hitachi KH230-3 crawler crane<\/strong> is its ability to install an <strong>auxiliary jib ranging from 9 m to 18 m<\/strong>, depending on project requirements. Technical specifications include:<\/p>\n<ul>\n<li>Jib lengths: 9.0 m, 13.5 m, 18.0 m.<\/li>\n<li>Jib offset angles: 10\u00b0 or 30\u00b0.<\/li>\n<li>Maximum lifting capacity:\n<ul>\n<li>At 10\u00b0: 6,500 kg for all jib lengths.<\/li>\n<li>At 30\u00b0: up to 6,500 kg with a 9 m jib, decreasing to 4,200 kg with an 18 m jib.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>However, it should be noted that <strong>jib lifting capacity must not exceed the main hook capacity at the same radius<\/strong>, and the weight of the jib itself must be deducted. This is a critical parameter when lifting lighter loads at height or in confined spaces.<\/p>\n<hr \/>\n<h3>Robust undercarriage and mobility on soft ground<\/h3>\n<p>As a <strong>crawler crane<\/strong>, the Hitachi KH230-3 features a strong undercarriage:<\/p>\n<ul>\n<li>Welded crawler frame that <strong>can be narrowed for transport<\/strong> and expanded using <strong>hydraulically controlled cylinders<\/strong>.<\/li>\n<li>Hardened alloy steel tracks with an <strong>anti-derailment mechanism<\/strong> for enhanced safety.<\/li>\n<li>Track links per side: 61 links, with a track width of up to <strong>760 mm<\/strong>, ensuring even load distribution on soft ground.<\/li>\n<\/ul>\n<p>Roller configuration:<\/p>\n<ul>\n<li>3 upper rollers per side.<\/li>\n<li>6 lower rollers per side.<\/li>\n<\/ul>\n<p>The crawler drive system uses <strong>hydraulic motors combined with reduction gearboxes<\/strong>, along with spring-applied, hydraulically released brakes, ensuring stable movement even on slippery or muddy terrain.<\/p>\n<hr \/>\n<h3>Powerful hydraulic system: Dual pumps and independent winch motors<\/h3>\n<p>The hydraulic system of the KH230-3 is highly regarded for its stable performance and optimized design:<\/p>\n<ul>\n<li><strong>Pumps 1 &amp; 2<\/strong>: Variable displacement piston pumps, <strong>300 bar<\/strong>, 200 L\/min.<\/li>\n<li><strong>Pump 3<\/strong>: Piston pump, 210 bar, 134 L\/min.<\/li>\n<li><strong>Pump 4<\/strong>: Gear pump, 45 bar, 32 L\/min.<\/li>\n<\/ul>\n<p>Main motors use swash-plate piston designs:<\/p>\n<ul>\n<li><strong>Winch motors<\/strong>: Equipped with load-holding valves to ensure safe lifting and lowering, preventing load drift.<\/li>\n<li><strong>Slew and travel motors<\/strong>: Fitted with multi-disc brakes for fast, smooth response.<\/li>\n<\/ul>\n<p>Safety relief valve settings:<\/p>\n<table>\n<thead>\n<tr>\n<th>Component<\/th>\n<th>Maximum pressure (bar)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Winch<\/td>\n<td>305<\/td>\n<\/tr>\n<tr>\n<td>Boom<\/td>\n<td>265<\/td>\n<\/tr>\n<tr>\n<td>Travel<\/td>\n<td>280<\/td>\n<\/tr>\n<tr>\n<td>Pilot control<\/td>\n<td>45<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>This configuration allows the machine to operate reliably in heavy-duty environments and sustain continuous multi-shift operations.<\/p>\n<hr \/>\n<h3>Simple yet effective control system<\/h3>\n<p>A notable feature of this 1990 model is its <strong>traditional mechanical control system<\/strong>, which is easy to operate and maintain:<\/p>\n<ul>\n<li>Separate control levers for main winch, auxiliary winch, slewing, and travel.<\/li>\n<li><strong>Dual throttle control (foot and hand)<\/strong> for flexible speed adjustment.<\/li>\n<li><strong>Multi-direction adjustable operator seat<\/strong>, suitable for long working hours.<\/li>\n<\/ul>\n<p>This design is particularly well suited to Vietnamese construction sites, where many operators are familiar with older-generation cranes featuring straightforward, sensor-free operation.<\/p>\n<hr \/>\n<h3>Large counterweight and solid overall structure<\/h3>\n<p>With a <strong>counterweight of up to 22,800 kg<\/strong>, the crane achieves excellent balance when lifting heavy loads. The honeycomb lattice steel boom design distributes forces evenly, reducing the risk of deformation or structural failure during off-center or prolonged heavy lifting.<\/p>\n<p>In addition, the entire machine is built from <strong>high-strength steel<\/strong>, increasing structural lifespan and reducing metal fatigue after decades of operation.<\/p>\n<hr \/>\n<h3>Main configuration summary<\/h3>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Main specification<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Model<\/td>\n<td>Hitachi KH230-3<\/td>\n<\/tr>\n<tr>\n<td>Year of manufacture<\/td>\n<td>1990<\/td>\n<\/tr>\n<tr>\n<td>Rated lifting capacity<\/td>\n<td>60 tons @ 3.7 m<\/td>\n<\/tr>\n<tr>\n<td>Main boom length<\/td>\n<td>Up to 34 m<\/td>\n<\/tr>\n<tr>\n<td>Auxiliary jib<\/td>\n<td>9.0 \/ 13.5 \/ 18.0 m<\/td>\n<\/tr>\n<tr>\n<td>Counterweight<\/td>\n<td>22,800 kg<\/td>\n<\/tr>\n<tr>\n<td>Winch motors<\/td>\n<td>Inclined piston type with load-holding valves<\/td>\n<\/tr>\n<tr>\n<td>Main pump type<\/td>\n<td>Variable displacement piston, 300 bar<\/td>\n<\/tr>\n<tr>\n<td>Track width<\/td>\n<td>760 mm<\/td>\n<\/tr>\n<tr>\n<td>Control system<\/td>\n<td>Mechanical, hand levers + foot throttle<\/td>\n<\/tr>\n<tr>\n<td>Boom connection<\/td>\n<td>Pin-connected<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<hr \/>\n<h3>Comparison with other crawler cranes in the same class<\/h3>\n<p>Compared with models such as <strong>Kobelco 7055-1<\/strong>, <strong>Sumitomo LS248<\/strong>, or <strong>Link-Belt LS-238<\/strong>, the KH230-3 offers:<\/p>\n<ul>\n<li><strong>Larger boom cross-section (1,400 mm)<\/strong> for superior load resistance.<\/li>\n<li><strong>Stable lifting capacity across various working radii<\/strong>, ideal for steel erection.<\/li>\n<li><strong>Hydraulically expandable crawler frame<\/strong>, allowing more flexible transportation.<\/li>\n<\/ul>\n<p>However, as a 1990 model, the KH230-3 lacks advanced electronic features, making it less suitable for projects requiring highly automated or digitally synchronized control systems.<\/p>\n<hr \/>\n<h3>Notes when purchasing or renting a Hitachi KH230-3 crawler crane<\/h3>\n<p>When choosing this model, contractors should:<\/p>\n<ul>\n<li>Check the hydraulic system condition, especially load-holding valves, winch motors, and crawler expansion cylinders.<\/li>\n<li>Inspect track link and sprocket wear, which directly affects mobility on soft ground.<\/li>\n<li>Select the appropriate jib length to match working radius and avoid exceeding safe limits.<\/li>\n<\/ul>\n<p>It is also advisable to work with suppliers that offer <strong>readily available spare parts<\/strong> and <strong>maintenance services<\/strong> to minimize downtime during operation.<\/p>\n<hr \/>\n<h3>Conclusion<\/h3>\n<ul>\n<li><strong>The Hitachi KH230-3 crawler crane<\/strong> is a classic choice for projects requiring a 60-ton lifting capacity, with proven durability and stability over decades.<\/li>\n<li>Its large boom structure, powerful hydraulic system, and expandable crawler frame make it suitable for a wide range of construction conditions.<\/li>\n<li>While not electronically advanced, the KH230-3 remains extremely <strong>reliable<\/strong>, easy to maintain, and well suited to technical teams in Vietnam.<\/li>\n<\/ul>\n<hr \/>\n<p>If you are interested in renting or purchasing a <strong>Hitachi KH230-3<\/strong>, please contact:<\/p>\n<ul>\n<li>\ud83c\udf0d Website: <a href=\"https:\/\/mayxaydunghanoi.com\/\">mayxaydunghanoi.com<\/a><\/li>\n<li>\ud83d\udcf2 Facebook: <a href=\"https:\/\/web.facebook.com\/khoandapcap\">fb.com\/khoandapcap<\/a><\/li>\n<li>\ud83d\udcde Call now: <strong>Ms. Th\u00f9y Linh \u2013 0899 601 755<\/strong><\/li>\n<li>\ud83d\udce9 Email: <strong><a href=\"mailto:hanoi.thuylinh2@gmail.com\">hanoi.thuylinh2@gmail.com<\/a><\/strong><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li><strong>Machine type:<\/strong> Hitachi KH230-3 hydraulic crawler crane<\/li>\n<li><strong>Year of manufacture:<\/strong> 1990<\/li>\n<li><strong>Maximum lifting capacity:<\/strong> 60 tons<\/li>\n<li><strong>Boom length:<\/strong> 34 m<\/li>\n<\/ul>\n","protected":false},"featured_media":7948,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[60],"product_tag":[],"class_list":{"0":"post-9181","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-crawler-crane","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.1 (Yoast SEO v26.6) -
