igus' P4 energy chain system is now available in two new sizes: P4.32 and P4.42. The P4.42 (42 mm inner height) in a 'heavy-duty design' is made for particularly demanding crane applications: high speeds up to 10m/s, long travels up to 800m, high filling weights up to 10kg/m. In contrast, the P4.32 (32 mm inner height) has been developed in a new design – lighter and slimmer – for high speeds when the installation space is limited.
Upper run and lower run are rolling offset over each other. Though the plastic profile rolls are not completely parallel, they still roll on a wide surface which greatly increases the lifetime of the chain. Additionally, the pitch of the chain link is equal for links both with and without rollers, so that the energy chain offers low noise and vibration in operation. The rollers themselves are fixed into the chain side links, whilst the auto-glide cross bars are made of tribologically optimized plastic. A special trough system also ensures that these chains run safely.
There is also a new cable for these energy chains: the Fibre Optic bus cable Chainflex CFLG.2LB, a universally applicable long-life bus cable, capable of small bend radii down to 40 mm. A highly abrasion resistant TPE jacket protects against mechanical damage as well as offering oil and chemical resistance.
