Tower crane manufacturer Potain unveiled its Igo T 99 telescopic self erecting crane on Friday 11 June.

Capacity is 6 tonnes and it offers a 48 metre jib with 56.5 metre maximum under hook height, with the jib elevated to 30 degrees.

The new model is designed to have compact dimensions for transport and a minimal footprint in use. The way it unfolds is designed to allow erection in a confined space.

Extending the jib to 45 metres gives a tip load of 1.5 tonnes. With the full 48 metres of jib out horizontally capacity is still 1.2 tonnes. Height-under-hook with the jib horizontal is 38.5 metres. Raising the angle to 30 degrees increases the vertical reach to 56.5 metres.

Six jib length options are available between 31.7 metres and the full 48 metres. Similarly for working height, up to three mast sections can be added, giving seven working heights between 20.5 and 38.5 metres.

Dimensions for transport

Total transport length is 15.65 metres by 4 metres high when fitted with 80 km/h axles. Existing Igo and Igo T transport axles can be used to move the new model.

Once on site its space requirement is 4.5 x 4.5 metres when erected. The new unfolding mechanism allows erection in narrow spaces close to buildings, Potain parent company Manitowoc said. Less space is needed because once the base is in place the crane unfolds from the top.

Levelling the crane is done by adjusting a support screw. Power is either from a 400 Volt, 50 hz or 480 Volt, 60 hz supply. Remote control operation and set up can be done from the same transmitter. It has a colour screen to show progress with erection, dismantling and operation.

Putting it to work

To operate from a cabin the options are an Ultra View or Ultra View Light cab. Manitowoc’s familiar and now standard Crane Control System (CCS) helps simplify operation.

Rope reeving is fixed at four falls so doesn’t need to be changed on site.

Design features include the electrical panel lid that opens upwards, giving sun and rain protection for maintenance technicians. In addition, the remote control transmitter and battery charger can be stored in there.

“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,” said Rémi Deporte, self erecting product manager. “This crane will enable customers to take on more jobs and achieve a higher return on their investment.”
