Liebherr-Mischtechnik recall: Product safety defect in truck mixers manufacturerd by Liebherr-Mischtechnik GmbH

What’s wrong

On truck mixers of the HTM 705 HTM 805 HTM 905 and HTM 1005 series manufactured from 2016 onwards the bolt connections on the rear drum bearing bracket may loosen over time due to stress during driving and/or cracks may occur on the welded joints of the pressure plates of the rear drum bearing bracket. This can cause the body to detach from the vehicle frame which in some cases has already led to the drum falling off the vehicle while driving. This poses a risk to life and limb; Liebherr are however not aware of any personal injuries to date. The facts of the matter are still being investigated in order to determine in detail the specific risk-relevant factors – such as the types of vehicles or chassis used usage-dependent load factors and the relevance of ageing processes.

The fix

Customers are advised to inform all employees of this recall. They are advised to inspect all affected vehicles immediately using the instructions attached to the safety notice (which has been issued to all UK customers and sales partners). If a crack is present remove the vehicle from service immedietely. In any case even if no damage is apparent contact your Liebherr sales partner for details on next steps and the retrofit which will be carried out free of charge.

How to check your vehicle
