With the Igo T 70, the crane has a two-section telescopic mast which increases its height through the addition of 6 m auxiliary sections. This allows the T 70 to vary its working height between 20 m and 32 m in increments of 3 m or 6 m. Without auxiliary masts, the the T 70 achieves working heights of 15, 17 and 20 m. David Havard, Potain’s product manager for self-erecting cranes, says the climbing design of the Igo T 70 is ideally suited to modern construction. “The addition of the 6 m auxiliary sections allows the Igo T 70 to climb in 3 m stages so it can rise with the construction as its stories increase,” he says. “It is also able to distribute heavier loads in shorter cycle times which translates to cost and time savings for end users.” Additional lifting flexibility comes from the T 70’s varying jib lengths. For example, the Igo T 70 lifts a maximum of 4 t and can lift 1.3 t at its top radius of 40 m. It can also lift greater loads at its tip when working with a shorter jib. The Igo T 70 load chart is strong, particularly towards the tip. The load chart combines well with Potain’s established LVF Optima hoist technology to boost on-site productivity. The LVF Optima hoist winch automatically adapts and optimizes hoist speed to the load on the hook. The crane will have wide appeal in a range of medium-size construction sites and benefits from a high level of quality design. The crane is very compact in transport and is even able to travel on a low loader trailer. Unlike other competitor self-erecting cranes, the Igo T 70 self-erects with the aid of a hydraulic system, which simplifies set-up. Operation on site is made easier with an integrated remote control complete with indicators.
