Tadano AR4000M

Starting from the mid-1990s, German-made all terrain cranes grew popularity in Japan due to their performance and mobility, both on and off road. Tadano responded to the market by introducing AR-4000M into the market in 1998, alongside with Japan’s largest all-terrain crane, AR-5500M. The 400-ton capacity crane comes with a five-section 51.2-meter main boom and equipped with Tadano’s Easy Sky Pin which allows extension of the boom using a single hydraulic cylinder and fixing it in position by pinning.
