A simple question that lies behind many calls to crane vendors:<\/p>\n\n\n\n

\u201cI need a crane to lift a 15-ton machine. What tonnage crane should I order?\u201d<\/em><\/p>\n\n\n\n

The answer isn't \u201c15-ton crane\u201d \u2014 and this is what causes many people to order incorrectly.<\/p>\n\n\n\n

Choosing crane capacity is not just about matching the load weight number with the number in the crane's name. There are important technical factors that must be taken into account: working radius, boom length, outrigger configuration<\/strong>, and many other variables that determine how many tons a crane can actually lift safely in actual field conditions.<\/p>\n\n\n\n

Choosing the wrong capacity can mean two equally bad things: a crane too small<\/strong> so the work cannot be completed and is potentially dangerous, or the crane too big<\/strong> so you pay more than you need to.<\/p>\n\n\n\n

This guide is here to help you make informed decisions \u2014 with easy-to-understand technical explanations, practical reference tables, and capacity guidelines for each job category.<\/p>\n\n\n\n

Choosing crane tonnage isn't about matching numbers \u2014 it's the working radius, boom length, and configuration that determine how many tons can actually be lifted safely.<\/figcaption><\/figure>\n\n\n\n

Fundamental Concepts You Must Understand: Nominal Capacity vs. Effective Capacity<\/h2>\n\n\n\n

Before we get into the selection guide, there's one fundamental concept that obligatory<\/strong> Understood, so that there are no errors in planning:<\/p>\n\n\n\n

Nominal Capacity \u2260 Effective Capacity<\/h3>\n\n\n\n

Nominal capacity<\/strong> is the number listed in the crane's name\u2014for example, \u201c30-ton crane.\u201d This is the capacity absolute maximum<\/strong> that can be lifted under the most advantageous conditions: minimum radius (load very close to the crane's body), shortest boom, outriggers fully extended, on a level and solid surface.<\/p>\n\n\n\n

Effective capacity<\/strong> is how many tons Indeed, you can lift it.<\/strong> in your actual project conditions \u2014 with a specific working radius, the required boom length, and existing site conditions.<\/p>\n\n\n\n

Effective capacity is always less than nominal capacity.<\/strong><\/p>\n\n\n\n

And how big the drop depends on the working radius:<\/p>\n\n\n\n

Working radius<\/strong><\/th>Estimated Effective Capacity<\/strong><\/th><\/tr><\/thead>
Minimum radius (3\u20134 m)<\/td>Approaching nominal capacity (80\u201395%)<\/td><\/tr>
Medium radius (8\u201312 m)<\/td>Approximately 40\u201360% of the nominal capacity<\/td><\/tr>
Long range (15\u201320 m)<\/td>Approximately 20\u2013351 TP3T of the nominal capacity<\/td><\/tr>
Maximum radius<\/td>Can drop to 10\u201315% of nominal capacity<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\u26a0\ufe0f The figures above are general estimates.<\/strong> Actual capacity at each radius varies depending on the specific crane model and configuration. Always use Load chart<\/strong> official from the crane manufacturer for accurate and safe lifting planning.<\/p>\n<\/blockquote>\n\n\n\n
