A truck mounted crane, also known as crane truck, integrates cargo transport and lifting function, widely used in construction, municipal works, mining, logistics and rural infrastructure projects. Many overseas buyers from Africa and Middle East make mistakes when selecting a knuckle boom crane or straight boom crane only by tonnage, ignoring the working radius and lifting moment.https://www.hjtrailer.com/construction-machinery/truck-mounted-crane/rhd-truck-mounted-straight-arm-crane.html
First, confirm your actual lifting demand. Do not judge the hydraulic crane by its nominal tonnage. Check the official load chart carefully. The lifting capacity drops obviously when the boom extends to a larger working radius. We suggest reserving 10%–20% safety margin for long-term heavy lifting, which helps avoid overload risks and extend crane service life.
Second, choose the boom type. Straight boom crane features stable lifting, long reach and high lifting height, suitable for open construction sites, material yard and mining works. Knuckle boom crane, also called folding boom truck mounted crane, folds compactly and flexibly, perfect for narrow streets, urban sites and limited-space handling. Besides, check outriggers, hydraulic system, overload protection and emergency stop function. Stable outrigger support is the key guarantee for safe operation on uneven ground. You also need to match the heavy duty truck chassis reasonably and choose LHD or RHD according to local road regulations.
