Ball bearings consist of an inner and outer ring, a cage and rolling elements. The cage is used to separate the rolling elements from each other in the form of balls. If the balls were not separated, they would run against each other and overheat. With high rotational speeds and friction of the balls, destructive […]
In the case of indoor cranes, the main power supply is usually provided via busbar systems and data transmission via wireless data systems. A drum solution (motor-driven or spring balancer) is generally used for large or harbour crane systems. Information about the drum solution can be found in the article with the title: Harbour / Large Crane Main Power and Data Supply.
For crane main power and data supply a motor cable drum or – for short travels – a spring tension drum is usually used. Busbar systems for the main power supply are also very common in indoor cranes. As an alternative to the two solutions, an energy chain can be used, which can offer various advantages.
Wear results of our new material iglidur® K250, which is characterised by a high flexibility and moisture absorption, are presented below. Compared to the igus classic iglidur® M250, the tribological properties could also be improved.
The demand for electric water pumps is huge. In addition to the cooling of motors and drives, air conditioning is also one of its tasks. The advantages of electric coolant pumps compared to conventional mechanical water pumps are their independence from the combustion engine. In this way, the electric pumps can be switched on and […]
