Modernizations

Haarup have made many modernisations of batching and mixing plants. The tasks have been to either procure a bigger production capacity or to exchange existing, worn equipment.

New gear

An old mixer from Hilac. A TV1500 needed a new gear. We have as usual exchanged the whole upper part starting with a new reinforcing ring to straighten the existing pan. The gear is supplied as a standard gear with new gates with safety limit switches on the gates and necessary inlets in the covering are installed in the covering from the factory. Installation of inlets in the covering could be made in Haarup's workshop due to a careful measuring of the existing equipment. Duration of the exchange was 5 days.

Modernization

Bucket elevator, filling hopper, and discharge belt

At a German Customer.

Renovation of existing filling system. At a German customer parts of an existing filling system were exchanged by Haarup. Bucket elevator, filling hopper, and discharge belt on top of the hopper were exchanged.

Modernization

Ready-Mix Station

A ready-mix station was modernized. The old drum mixer was exchanged by a modern counterflow mixer. Furthermore, the plant was prepared for a later exchange of aggregate bays by a modern hopper system, which has later been added.

Modernization

Modernisation of Complete Plant

The task was to exchange a hopper system built of steel containers, mixers, admixture weigh hoppers, concrete travelling buckets and not at least the control.

Modernization

New Batching Units

Old, rusty steel chutes were exchanged by new, hot-galvanized steel chutes. The batching units were renewed by batching belts and the weigh belt was exchanged by a new, hot-galvanized weigh belt. Furthermore, the mixer was exchanged and the logistics in the batching pit was simplified.

Modernization

Filling of Sand and Stones

Filling of sand and stones with a customer in Norway. Here Haarup have changed the filling so that this takes place by a transport belt to a distributing conveyor, which is placed on top of the hoppers. Previously there was a ramp to the hoppers, which took up much space in the factory area. Now the ramp has been removed and has been replaced by the inclined belt and the complete filling system. Today the top of the hoppers has been covered.

Modernization

Exchange of mixer and hoist.

Haarup has exchanged the mixer and hoist at a customer in Norway. There was not much space in the height and to the sides. The hoist rails were divided in 3 parts and the mixing pan and gear were separated in order to have space for the mixer. The mixer was placed in the same place as the old mixer and the same holes in the concrete deck for the discharge openings were used. The duration of the installation was 8 days.

Modernization

Space for extra Cement Silo

An existing plant had to produce white concrete. Therefore, an additional cement silo was added in the narrow space between two halls. It is difficult to see in photo 2, but there are 2 silos behind each other.
