For decades Potain has built tower cranes that are easy to assembly, flexible in configuration and simply to use, and the Potain MDT 389 topless crane is no different.
The MDT 389 is well suited to crowded construction sites where space is tight and multiple cranes are needed. Like other topless cranes it has been designed to allow more cranes to over swing in a smaller area.
Louw Smit, sales director of Crane & Hoist Equipment SA, the sub-Saharan distributor for Potain tower cranes, says there are a host of features which make the Potain MDT cranes stand out from the competition.
The complete range, including the MDT 249, MDT 259, MDT 269, MDT 319 and the MDT 389, is equipped with Manitowoc’s Crane Control System, or CCS. CCS is a standardised, user-friendly operating system on all Potain tower cranes.
“CCS assists users to enjoy the highest levels of comfort, flexibility, ergonomic control and, most importantly, improved lifting capacity. The enhanced productivity achieved as a result translates into a faster return on investment for Potain crane owners,” Smit says.
In addition to having a fresh and modern design that allows for ultra-fast ground preparation and assembly, the Potain MDT range easily beats the competition when it comes to transportation.
“For example, the turntable, cab mast and Ultra View cab travel in a single compact package, while the counter jib can be folded and the winch platform can be sized to take up less space,” Smit explains. Another advantage is that the mechanisms are grouped in a central technical zone for easier access and maintenance.
As part of its standard features, the Potain MDT 389 is equipped with Manitowoc’s CraneSTAR, a GSM data transfer system that provides information on crane location and operation to support fleet management.
There are two versions of the Potain MDT 389, one with a 12 t maximum capacity and the other with a 16 t maximum capacity. Both versions have up to 75 metre (m) of jib available. The 12 t version can lift 3.4 t at its jib end, while the 16 t version can handle 3.3 t.
Potain also offers a smaller range of CCS equipped cranes, the Potain MDT City line, which includes the MDT 219. Other cranes in the range are the MDT 109, MDT 139 and MDT 189.
Like the Potain MDT 389, the MDT 219 is the highest capacity model in its range. There are two versions of the Potain MDT 219, one with an 8 t maximum capacity and one with a 10 t maximum capacity. All are evolutions of previous Potain MDT City cranes with jib lengths ranging from 55 metres to 65 m and hoisting capacities ranging from 6 t to 10 t.
Smit says the incorporation of CCS into the new range of Potain topless city cranes helps contractors get work done faster and with greater precision. “Aside from the enhanced levels of comfort and ergonomic control, this technology also delivers more precise control in positioning loads as well as increased capacity,” he says.
In fact, for the Potain MDT 219, the inclusion of CCS gives the crane a load chart advantage of up to 12.5% over the MDT 218 A, the equivalent pre-CCS topless city crane from Potain.
These cranes can be engineered to incorporate one of two new crane operator elevator solutions which provide fast and efficient transportation for the operator to and from the cab. Both systems comply with the highest levels of regulation as well.
One of the solutions, CabLIFT, exclusive to Potain cranes, has a slender design allowing it to fit inside all K-mast systems from Potain. It comes in three widths, 1.6 m, 2.0 m and 2.45 m. It is also compatible with all tower crane bases, fixing angles, chassis and cross-shaped bases. CabLIFT’s intelligent design includes a service platform above the main car that provides comfortable access and safety for the erection technicians during the mast assembly process and crane erection.
The other operator elevator solution is TCL, an externally-mounted system.
Potain has long been at the forefront of topless tower crane development, and with the introduction of CCS to its tower cranes, the brand is securing its market leadership position for years to come.
