The Mantis 3612 telescopic boom crawler crane has a 18 Us ton (16.3 m) max. lifting capacity at a wide 12 ft (3.66m). While no longer in production the 3612 is still supported by a global network of Tadano-Mantis Crane distributors. 

Like all Mantis cranes, the 3612 picks and carries its entire load chart through 360°. The extraordinarily low center-of-gravity stability enables this crane to travel at full nominal capacity with its tracks retracted for reduced width; or with counterweight removed to further reduce ground bearing pressure or even with the boom partially telescoped.
