14 container cranes in use for 12 years

Energy supply on container cranes at HHLA Container Terminal Altenwerder

Profile

  • What was needed: energy chains type E4 5050 RHD, chainflex cables for movable applications
  • Requirements: a space-saving and robust cable solution had to be found. The energy chain and cables are confronted with a high handling frequency and a 54-meter-long travel. In addition, there were high dynamics with speeds of up to 240m/min as well as constant weather loads.
  • Industry: crane
  • Success for the customer: the new energy and signal supply system offers a longer service life and allows a significantly more compact design. In an interim check 12 years after installation, the first chainflex cable set was still in place, having handled around 100,000 container movements at that time.

Problem

Solution

The first chainflex cable set is still installed in the energy chains. [...] They have probably handled several 100,000 container movements so far.
