Two recent additions to the Liebherr concrete production cast

Liebherr provides concrete technology for the production of ready mixed concrete and to supply prefabricated or pre-cast concrete element production plants. Providing concrete production solutions from the smallest site to major construction projects, the company develops and manufactures mixing plants, including mobile mixing plants, truck mixers and concrete pumps. Its range also includes other related products including conveyor belts for truck mixers and plant control systems. Liebherr’s concrete mixing plants are in use worldwide.

New stackable silo feature for Liebherr mixing plant
Liebherr’s Mobilmix 2.5 concrete mixing plant was unveiled at bauma 2016 and offers especially flexible operation because it is easy to transport and has a fast installation time. The Mobilmix 2.5-F is characterised by its folding mechanism and integrated assembly components including steel foundations, control plus mixer and weighing platforms.

The Mobilmix 2.5-F is equipped with a state-of-the-art twin shaft mixer, a new generation of Liebherr twin shaft mixer that has been completely reworked and with which the plant achieves a theoretical output of up to 115 m³/h.

Other highlights of this plant are the steel fibre dosage in the area of the elevator truck, the increased cement silo for optimal material flow due to a small gradient in the angle of the feed screw and hot air / hot water heating for concrete production in winter.

But there is now another brand new feature of the Mobilmix 2.5-F mixing plant that makes it an even more attractive proposition for construction projects: stackable silos. With its stackable silos, the Mobilmix 2.5-F not only benefits from fast set-up times but also from a small footprint. This means that the Mobilmix 2.5-F can be used in locations that would not previously have been possible due to a lack of available space. This widens the range of construction projects for which the Mobilmix 2.5-F is a viable option.


Liebherr’s new generation of truck mixers with online configuration tool
In January Liebherr began sales of its new truck mixer generation 05 and delivery has now begun with the most popular model, the HTM 905.

LICRO 500, an extremely wear-resistant special steel manufactured exclusively for Liebherr, is used for the entire drum and increases service life. The drum’s empty weight has been reduced by up to 300 kg compared to its predecessors, which benefits the payload. Edges prone to accumulating dirt have been replaced by smooth surfaces to make cleaning easier. The optional Litronic-EMC drum controller controls the diesel engine speed according to need when loading and unloading and the constant speed drive prevents unnecessary drum revolutions in transit with resultant fuel savings and reduced wear.An innovative platform concept allows accessories to be installed in a range of positions. This flexible platform design creates many possibilities with more options and accessories to come. All control elements for the new truck mixer generation have been configured to optimise user-friendliness. The concrete transfer chute can be completely swung out to the side without projecting beyond the outer dimensions on the side of the vehicle.

This is beneficial for emptying into large concrete buckets and improves access for cleaning. To improve the flow angle when transferring concrete, the transfer chute has been offset by around 120 mm upwards. The new chute brake can be locked to the slewing chute quickly and securely with one hand movement. The side storage point for the extension chutes has been lowered to make removal easier. A new ladder platform provides more space and the extension ladder is made of aluminium, making it lighter and easier to operate. An optional operator roof at the rear of the truck mixer protects the driver from the elements.

New angled steps and an enlarged platform make it easier to work on the upper vehicle rear. The railings have a larger diameter for improved grip and safety is further increased by the optional Litronic-EMC drum controller: it prevents operating errors such as sudden changes in rotation direction. The rear control unit can be switched off during transit to prevent unauthorised individuals starting the machinery and the water capacity in the mixing drum has been increased to prevent the drum's contents spilling.Prospective customers can use an online configuration tool to put together their own HTM 905 choosing between normal or lightweight construction, selecting option packages, specifying accessories and deciding on paintwork. During all configuration steps possible payload in m³ of concrete is calculated live and the customer can see how their truck mixer would look from different angles. Individually created configurations can be saved or requested directly. The configuration tool is available at: www.truck-mixer-configurator.com.
