Manitowoc has introduced the new Potain Igo T 99 self-erecting tower crane, which provides improved capacity and reach when compared to previous Igo models but from the same compact footprint.
The Igo T 99 features a 6t maximum capacity and maximum reach of 48m. With the jib extended to 45m, it can lift 1.5t at the tip. And when it’s configured with 48m of jib, it can lift 1.2t. According to Potain, the new crane also features a long vertical reach, with its height-under-hook reaching 38.5m at horizontal and reaching 56.5 m when the jib is raised to 30°.
For maximum versatility on the job-site, the Igo T 99 can work with six different jib lengths: 31.7m, 32m (in a folded jib position), 33.8m, 40m, 45m and 48m. Three additional mast sections can be added to the crane, providing seven working heights that range from 20.5-38.5m.
According to Manitowoc, the “impressive capacity and reach from this compact crane will enable customers to bid for and complete more jobs”, as its travel and on-site dimensions make the crane easy to transport and ideal for job-sites with tight working conditions.
Transport to the job-site is made easy by the Igo T 99’s compact dimensions. It has a total transport length of 15.65m and height of only 4m when fitted with 80kmh axles. It is compatible with all current Potain Igo and Igo T transport axles which adds versatility for customers with more than one Igo in their fleet, said Manitowoc.
The manufacturer added that the Igo T 99 features the compact footprint and ability to work on constricted jobsites that previous generations of Igo cranes are known for. Its footprint measures 4.5m by 4.5m when erected, and a new unfolding mechanism enables the crane to be erected in narrow spaces close to buildings. This mechanism requires less ground area because the crane deploys from the top after the base is already erected. Levelling the Igo T 99 is done simply by adjusting a support screw, and the crane can be powered from both 480v 60hz and 400v 50hz power sources.
With Potain Smart Set-Up software, operators can fully erect and decommission the crane using only its remote control. A large, colour screen shows step-by-step progress through an intuitive interface and optimized ergonomics make it comfortable to use. Operators also use the remote for lifting functions. An Operator Control Function enables the pre-programming of three driving profiles so users can customize crane behaviour to their preferences.
For operators who want to operate from a cab, they have their choice of an Ultra View or Ultra View Light Cab. Cab access is compliant with the latest standards and offers a comfortable and productive work environment. These cabs utilise the Manitowoc Crane Control System (CCS) that has become standardised across a variety of Potain cranes.
During operation, the Igo T 99 is quick and productive, said Manitowoc. High-Performance Lifting (HPL) technology delivers high-speed hoisting even when working at maximum load and various speeds can be selected by the operator to match the current operation. With a permanent four falls, there is no need to change the rope reeving on the jobsite.
A newly designed electrical cabinet door opens from the top for maintenance access, providing handy weather proofing for technicians. The electrical cabinet also includes convenient, dedicated storage for the remote-control transmitter and battery charger. Manitowoc’s CraneSTAR Diag tool ensures the Igo T 99 stays up and running, flashing warning indicators for working hours, greasing level, troubleshooting, maintenance and much more.
Rémi Deporte, Manitowoc’s product manager for self-erecting cranes, said: “The newly launched Potain Igo T 99 from Manitowoc is a highly versatile telescoping self-erecting crane with streamlined transport options and easier-than-ever setup and operation. This crane will enable customers to take on more jobs and achieve a higher return on their investment.”
