Nord Drivesystems installs more than 1.700 motorreductores in a new system of manipulation of luggages

Miles of motorreductores speed up the operation of the international airport of Frankfurt

Editorial Interempresas18/10/2012

The airport of Frankfurt expects a strong increase in the volume of traffic, so much of commodities as of passengers. The new track of the northwest finishes to go in in operation, a new terminal finds in phase of planning and this autumn of 2012 will open the new dock of ship To-Plus, increasing like this the number of megarreactores To380 (the greater aeroplane of passengers of Airbus) that will be able to process of simultaneous way. With the end to keep the time of load of luggage underneath of 45 minutes, even with more aerial traffic and some measures of hygiene reinforced, needs a technology of effective manipulation and very reliable. The wide system of manipulation of luggages in the new dock, supplied by the group Beumer, is accionado by motorreductores of Nord Drivesystems.

The To380 offer more seats and space of load that any another commercial aeroplane and are prepared for flights of long distance. Therefore, they will be the method of transport chosen en el futuro. The airports with the necessary infrastructure will have a clear advantage.

Greater optimisation of the space and total accessibility: the installation of storage of luggage of several flats is entirely automated and linked to the configuration of the transport.

Installation for a fast manipulation of luggages

The airport of Frankfurt manages at present until ten aeroplanes of fuselaje wide at the same time. The new dock To-Plus will increase this number in seven and besides will offer the sufficient space to process several smaller aeroplanes. The provider of internal logistics Beumer is building the new system of transport of luggages, that has more than seven kilometres of length and will connect in 2012 to the existent system. The technology of transport with the strip transportadora no only has to be always available, but it also has to be able to carry of reliable form the luggages to the correct destination in less than 45 minutes.

Nord Drivesystems Has installed more than 1.700 motorreductores in this wide system, with near of 2.000 elements of conveyor and more than 100 unions. Thanks to the novelties in the design and the construction can use units smaller in a lot of points, what carries to lower costs of installation and of operation. At the same time, they have harmonised in the measure of the possible the sizes of the accionamientos and the number of the models used has reduced with the end to improve the logistics and reduce the inventory of spare pieces, what improves consistently the profitability. The ease of maintenance and repair also is guaranteeed: the accionamientos are interchangeable and are mounted with few screws and an only electrical connector, and can replace in very little time. “For this project, Nord gathered to a team of sales, engineering and personnel of logistics that was to our disposal anytime and answered quickly to our worries”, says Klaus Ruhe, manager of the project in Beumer "The relative requirements to the logistics of the airport attended with precision and flexibility”.

Already it was in a conveyor of band or of rollers, the accionamientos Nord modular and interchangeable guarantee a high operative availability during a long life of service, practically without need of maintenance, an easy accessibility and an effort of minimum replacement.

Motorreductores Of high performance

The provision of power of the motors vary between 0,55 and 3 kW. All the motors of 0,75 kW nominal and of upper power are models IE2 that, for the application of the conveyor, offer a greater performance and consume less power that the accionamientos before used of class EFF2 (now classified like IE1). To end to apply the Directive on ecological design (Ecodesign), NORD uses metallic sheet of very high quality with small losses and material more active in the stator. Besides, it has increased the copper used in the slots of the stator and has optimised the diagram of bobinado.

Thanks to these constructive changes, the motors IE2 of NORD offer a margin of operation wider, that has taken into account in the configuration of the accionamiento. In some circumstances, has been able to install motors smaller that those that previously was possible, because of the greater saving of power. In function of the size of the engine, some models can operate until to 150% of the capacity of nominal power, while they keep a high efficiency. In comparison with his models direct predecessors, the motors of type IE2 offer pairs of start and dump (maximum) greater and develop less residual heat.

Experience in the manufacture of reductores

The reductores employed for the regulation of the speed in the installation are in his majority reductores conical SK9012.1, complemented by a series of reductores coaxial SK372.1. Roughly the half of the accionamientos are instrumented with brakes. Nord Is not only a provider on a large scale of products and solutions of accionamiento, but it also has a wide range of manufacture that includes motors, frequency converters, and all the pieces of a gear, from carcasas and axles until piñones and sinfines. The construction of carcasas follows the principle Unicase, established by Nord in 1981. Without cords of welding, cover atornilladas neither surfaces sealed, the carcasa of an alone piece with the threads of the integrated cheese cheese axis presents a resistance to the maximum torsion and ensures some excellent capacities of radial and axial load. To improve the precision and avoid the wear and the break, all the surfaces of rolling mechanise in an alone operation. Like this, no only the reductores reach an useful life longer that the models manufactured conventionally, but they also are particularly silent because of a softer operation.
