LIEBHERR - First-rate painting line

Liebherr uses WAGNER equipment to coat cranes

The coating of large workpieces presents manufacturers with exactly the same challenges. The Liebherr plant in Ehingen was thus looking for a customized solution to paint the components of its telescopic and lattice boom cranes that measure up to 15 meters in length. An impressive painting line has now been in operation there since October 2016 – it is equipped with four painting booths, several 1,000-liter paint containers, over 2,000 meters of pipes, 35 pumps, and five mixing and dosing systems from WAGNER. The system was planned, supplied, installed, and commissioned by Thüma Maschinenbau und Service GmbH from Gotha.

At a glance

  • Impressive painting line was installed – 4 painting booths, several 1,000-liter paint containers, over 2,000 meters of pipes, 35 pumps and 5 mixing and dosing systems
  • Innovative loop line concept with a switchover between the flow and return pipe to bridge the large distances between the paint supply and painting booths
  • Central data collection – Liebherr is able to record times, paint quantities per project and flow rates, and to evaluate them in a VOC balance sheet
  • Liebherr takes advantage of new advances in technology and benefits from a resource-friendly painting line

Customer challenge

The coating of large workpieces presents manufacturers with exactly the same challenges. The Liebherr plant in Ehingen was thus looking for a customized solution to paint the components of its telescopic and lattice boom cranes. Before the project started, Liebherr had positive experiences both with Thüma Maschinenbau und Service GmbH and with WAGNER products.

Our solution

The entire system consists of one central paint supply container and four painting booths. Seven Puma 8-300 pumps from WAGNER transport the components at low pressure via the piping systems to the painting booths. On the booths, 28 IceBreaker high-pressure pumps from WAGNER increase the pressure of the materials and supply the five 2K COMFORT mixing and dosing systems. One special feature of the system concept is that minimal quantities of the subsequent top coat can be mixed in with the primer in each 2K mixing and dosing system. The white or gray primer is thus colored in such a way that the subsequent top coat application is optimized and has a more brilliant appearance in the end.
