The hydraulic hoses used in steel chains for this Power Catwalk application wear out very quickly, so an alternative was sought. Because the YE.42 hybrid chain consists of steel side plates, which ensure a 100 % greater unsupported length (compared to plastic chain of the same size), and the plastic crossbars, which have been tried and tested for more than 35 years, the YE series hybrid chain solves the customer's wear problem.
