Liebherr has supplied its 100,000th concrete truck mixer - an HTM 905.
Heinz Transportbeton Ingolstadt (Heinz) is the landmark customer. Heinz’s management visited the Liebherr factory in Bad Schussenrieda, a spa town in Baden-Württemberg, Germany, to collect their milestone machine. The company has been a loyal Liebherr customer for around 45 years.
Liebherr manufactures 12 concrete truck mixers as well as the ultra-modern concrete mixing tower type Betomat.
Heinz started 45 years ago in 1975 with a Liebherr Betomix 50 and has been convinced of Liebherr quality ever since. In addition to ready-mixed concrete, Heinz is also successful in the building materials trade and earthworks sectors.
The landmark HTM 905 – 5 stands for new generation – has a 9m³ nominal volume. Generation 5 offers a whole host of advantages over its predecessor, says Liebherr. The truck mixer empty weight can be reduced by around 180kg, increasing the available payload. During development, Liebherr paid particular attention to the cleaning of the concrete truck mixer: edges susceptible to dirt are said to have been rectified, and smooth surfaces created. The result is lower susceptibility to dirt and reduced cleaning effort.
Liebherr’s optional Litronic-EMC drum controller controls the diesel engine speed according to need when loading and unloading. The constant speed drive prevents unnecessary drum rotations during the journey. This is said to save fuel and reduces wear. Furthermore, the Litronic-EMC is also said to increase safety by preventing operator errors such as changing the direction of rotation suddenly. Also, the rear control unit can be switched off during the journey so that operation by unauthorised people is not possible.
The innovative platform concept in the new Generation 5 concrete truck mixer provides flexible attachment options for accessories. Storage compartments, holders or extension chutes can be installed in various positions. Optional equipment can also be subsequently installed. All controls are configured to be extremely user friendly.
The concrete transfer chute on the new Liebherr truck mixers can be completely swung out to the side without protruding over the outside of the vehicle. This makes discharge into large concrete buckets and access for cleaning work easier. The transfer chute is offset by around 120mm upwards, which improves the flow angle when transferring the concrete.
The storage locations are now installed slightly lower on the vehicle in order to make removing the extension chutes easier. The new ladder platform provides more space, and the extension ladder is made of aluminium, is lighter and can be operated easier.
The new angled steps and the enlarged platform make working on the new truck mixer’s upper vehicle rear easier. The railings have a larger diameter for a better grip. The water capacity in the mixing drum is also increased. This prevents the drum’s contents spilling out when transporting fluid consistencies in particular.
A comprehensive concrete technology supplier, the Liebherr range includes truck mixers, conveyors for truck mixers, concrete pumps, concrete mixing plants, mixing systems and residual concrete recycling plants.
Liebherr started its truck mixer programme in Bad Schussenried in 1967. Today, the company manufactures its truck mixers at five locations – Germany, Brazil, China, Thailand and Saudi Arabia. All locations between them have now reached 100,000 units produced.
