The new igus P41.80RI roller chain with integrated iglidur plain bearings has been doing its job on the gigantic ship unloader cranes from EMO B.V. in Rotterdam since the end of 2015. EMO B.V. is one of the largest bulk terminals in Western Europe. With a trolley travel of over 100 m, a travel speed of up to 4 m/sec and an additional load of over 50 kg/m, it is one of the most demanding energy chain applications in the port crane sector.
When threads are used in heavy-duty applications, they must meet many requirements. One of the most important aspects for heavy loads is the stability of the threads under high axial and radial loads. But does this also work with lead screw nuts made of polymer? Clear answer: Yes! The drylin lead screw technology development team has set itself the task of developing a robust alternative to the flange lead screw nut.
As versatile as the various indoor crane designs are, their areas of application are just as varied. The advantages of the energy chain over other cable or power supply systems are particularly evident under adverse operating conditions. Suitable for both trolley drive and crane drive, heavy-duty energy chains, with and without integrated skate wheels, can master even the most difficult operating conditions.
