Concrete block making machine RH 2000

The RH 2000 is the high end machine from the company HESS. Many years of experience in machi-ne construction combined with latest progress in technology make this machine the front-runner of the concrete product machines. Easy operation and requirements on maximum safety guarantee the highest degree of economic efficiency for the customer.

Tamper head vibration Face mix filler box with planing roller, pneumatic scraper and rotating brush

High performance hydraulic system of the M-Version

Block making machines of the M-series are equipped with a CNC-control unit. All movements of the axes of tamper head, mold and filler box are monitored and precisely controlled to 1/10 of a mm. All axes communicate with each other to enable overlapping travel movements for optimum cycle times. A tamper head brake is not requiered as the hydraulic cylinders can be held in exact position by the control. The integrated CNC control guarantees highly precise movements with optimum cycle times. Furthermore these harmonic motions ensure an extreme low-wearing operation of the machine.

Cost effective solutions

The RH 1400 combines cost efficiency with optimized performance for high quality concrete pro-ducts. In combination with the handling system, especially designed for th RH 1400, it is possible to reduce investment costs, hereby retaining the advantages of a big board plant.

Pneumatic tamper head clamping

A precision machine with high output

The RH 1500 is a powerful machine for high production volume. In spite of the short cycle times the machine stands out for smooth mechanical movements due to the hydraulic system and a special electrical control. A harmonic co-operation between electrical and hydraulic machine func-tions guarantees a reliable and high output production of concrete products.

Concrete block making machine RH 760 / RH 780

Machines of the RH 700 series are designed for the production of 2,5 up to 6 blocks per board.The fully diagnosable high performance hydraulic system and the full automatic mold change with height adjustment, guarantees highest efficiency. Designed as a replacement machine the RH 700 series allows the use of an existing mold pool and foundations.

Modular expandable - suitable for your needs

What makes this machine type stand out is its modular structure. Depending on the market situ-ation the customer can choose the level of automation for the wet line and the dry line. Later on it can be upgraded to a completely automatic system. With the RH 600 the production capacity can be increased in an economical way so the customer can react to increasing market demand.

Our patented VarioTronic system consists of a simple mechanical structure and a fully electronic control which is reliable and extremely accurate. Frequency and amplitude can be adjusted indivi-dually and produce maximum results during mold filling and main compaction. Using asynchronous servo motors, vibration angles adjust extrem-ly fast. This causes a short vibration time and a high product quality. The HESS oil-bath vibration features vibrating shafts which are individually

mounted in closed casing which are filled with oil. The system provides significant advantages:

• permanent lubrication of bearings• running dry inside the casing is impossible• increased lifetimeThe RH 500 has a heavy duty, compact structure with advanced electronic, pneumatic and mecha-

nical modules. It can produce slabs, pavers, hollow blocks and similar concrete products in modera-te production output. With a production height of 25 up to 300 millimeters it offers a wide range of products. The mechanical height stop allows a production to a specific and accurate height.

The HESS oil-bath vibration /Filler box planing roller

The HESS oil-bath vibration

Filler box planing roller

The HESS Group has developed a new, adaptable system for the face concrete filler box - the planing roller (pat. pen-ding). It is a steel roller replacing the front stripper frame of the filler box. The roller is driven by a frequency controlled mo-tor via a chain and independent from the movement of the filler box. There are se-veral advantages when producing paving stones with the driven planing roller: The roller prevents that concrete is „dug“ out of the mold when the filler box re-turns to home position. This effect beco-mes especially apparent when more wet concrete is used or large-sized pavers are manufactured. Therefore the planing roller enables the production with particularly wet concrete mixes which on the other hand improves the color in-tensity, provides a more compacted surface and produces a better compound between course and face concrete. As the product surface absorbs less water, a possible spalling of the face concrete layer during frost is also obviated. Molds for large-sized paving stones can be charged evenly wi-thout repeated forth and back movements of the filler box. This means more efficient cycle times and high-quality end products. The filler box planing roller is available for the RH 2000 and RH 1500.

Handling systems for concrete block making plants

Wet side

Stone layer doubling unit and cuber

To make the production process of concrete products economi-cal, efficient transfer and handling systems are necessary along-side mixing and production machinery. To transfer, buffer and store fresh and cured product, HESS offers a wide program of proven solutions.

Especially with respect to paver production, cycle times under 10 seconds are no longer a rare occurrence. Therefore, the logistics and the product flow between the wet and dry sides are deciding factors in the quality and efficiency of the concrete production.

Fully-automated handling systems, which are designed for indivi-dual customer needs are becoming more and more important in the production of concrete stone products.

The demand for different shapes and surfaces grows constantly, especially when a manufactured product is required to have the appearance of natural stone.

HESS has responded to this demand with the development of several surface treatment systems, which can be integrated into fully- automated production plants. This patented equipment is combined with the necessary handling systems for:

• splitting• blasting• washing• milling• tumbling

of concrete products.

Surface treatment creates variety

Cutmaster Tumblemaster

Surface treatment of concrete products can be succeeded in two different manners: Wet side treatment between machine and elevator or dry side treatment is mostly realized before cubing with bypass solution. An optimized integrated surface treatment line for cured products helps to reduce the amount of operation processes and hereby minimize additional costs.

Patented solutions provide producers the op-portunity to gain a competitive advantage and expand their product range with moderate in-vestment expenses.

SM series compulsory mixer

Separate drives for perfect mixing results in short mixing intervals

Mixers of the SM series provide the perfect solution for making concrete types used in the produc-tion of paving stones, slabs, kerbstones, hollow blocks as well as pipes and manholes or for precast concrete elements and ready-mix concrete. Thanks to their high mixing intensity, planetary mixers are particularly suitable for the production of concrete types with low water/cement ratios to achie-ve earth-moist concrete and self-compacting concrete types.

Many companies all over the world use HESS Group mixers with great success. Their outstanding characteristics are: a very long service life, a high degree of reliability, excellent mixing performance and minimum maintenance.

SM series mixers just give better mixing results

According to ISO 18650 definitions, mixing results with a variation coefficient of under 7.5% are considered adequate. The faster a low coefficient is achieved, the better the mixer. The SM mixer actually achieves a variation coefficient of less than 1%! And at very short mixing intervals!
