With the Lock & Turn Quick Access, the International Social Security Association (ISSA) honors a safety-relevant solution for the impact crusher MOBIREX MR 100 NEO/NEOe. This system reduces the work risk to operators and facilitates access to the crushing chamber.
The Safety Award of the ISSA Section on Machine and System Safety honors developments that make a demonstrable contribution to improving occupational safety. Evaluation criteria include unique features, the risk reduction achieved and ergonomic aspects.
The Lock & Turn Quick Access system installed as standard in the MOBIREX MR 100 NEO makes it possible to open and close the crusher unit housing at the push of a button – and only after the rotor has come to a complete standstill. This defuses a central hazard point in the operation of impact crushers: Access to the crushing chamber during or immediately after machine operation. Previously, opening the crusher housing required the manually loosening multiple bolted connections, mostly in hard-to-reach areas. This resulted in a higher workload and greater risks for the operators. These steps are now eliminated with Lock & Turn Quick Access, and any material bridging can be cleared in the shortest possible time. Tool-free opening of the crusher is a further positive feature that guarantees fast service and maintenance. “Our ‘Lock & Turn Quick Access’ allows our customers to open the crusher very quickly at the push of a button. This takes a mere 30 seconds. The operator thus has a full view of the crushing chamber very quickly and without any manual intervention at all. A blow bar replacement, for example, is extremely convenient”, says Laurin Winter, Product Management for mobile impact crushers at Kleemann.
The jury emphasized that the solution not only increases safety but also simplifies workflows. Since the housing can be opened within approximately 30 seconds, visual inspections and maintenance work can be carried out faster. This facilitates the early detection of wear.
With this award, the ISSA recognizes a safety engineering advancement that responds to a central risk in the operation of crushing plants. The combination of safety, simplified handling, and the ability to perform regular inspections without high effort convinced the jury.

New Kleemann Plant Marks Commitment to Industry
In early 2010 Kleemann GmbH completed its new headquarters and state-of-the-art manufacturing plant near Göppingen, just east of Stuttgart in south-central Germany.
The new plant marks Kleemann’s commitment to the minerals processing industry and incorporates the highest production technologies for the manufacture of aggregates and minerals processing equipment.
This new “greenfield” manufacturing plant is making Kleemann mineral processing equipment more available, and will speed product delivery in North America in coming months. “With 350,000 sq. ft. of production area and 40,000 sq ft of administration area, Kleemann will excite the market with new models and features for 2010,” said Evan Clarke, vice president.
For over 150 years Kleemann has led the minerals processing industry with design ingenuity, producing crushing and screening equipment for many leading markets. Since being acquired by the Wirtgen Group in 2006, the company has experienced dramatic growth which has led to reinvestment by the group to help streamline production and allow for greater volume for its new expanding markets.
“As Kleemann gathers momentum within the United States and Canadian markets, and new dealers take on the product line, many customers are seeing the ‘Kleemann Advantage’,” Clarke said. “We bring to the market a wide range of track mobile crushers and screens with many unique features.”
The new plant utilizes the most modern German high-tech manufacturing processes, including short internal product assembly lines. On the new 1.34 million sq. ft., site, the new manufacturing facility covers an area of 376,736 sq. ft., complemented with a 43,055 sq. ft. administration building. The oversized interior capacity of the new main production facility accommodates the enormous dimensions of Kleemann’s largest crushing and screening machines.
In the plant’s central warehouse contains two storage zones in which some 10,000 items are stocked. “On average, 200 items with a total weight of 8.8 tons are handled here each day,” said Kleemann central warehouse manager Martin Zemmel. “We really benefited from the know-how of the other Wirtgen Group companies when building our new facility.”
Kleemann’s new painting facility for large parts is one of the largest such facilities in Germany, with a tremendous load-bearing capacity of 33 short tons, and around 21,500 sq. ft. of floor space. Kleemann’s switch-over from wet spray painting to powder-coating not only marks a major step towards boosting surface quality, but also has far less of an environmental impact, with the system far exceeding the requirements of the EU environmental guidelines.
Kleemann’s Roots Run Deep
Kleemann is a newcomer to the North American aggregate processing market, but its roots lie deep. Established in Germany in 1857, Kleemann was acquired by Wirtgen Group in 2006. Today, a growing network of equipment distributors and dealers is enabling Kleemann Inc. USA to boost its domestic profile and serve customers in North America.
Today Kleemann manufactures and markets a broad range of durable, productive mobile and stationary processing equipment and technology for crushed stone, demolition waste and mixed construction waste.
Kleemann’s product brand names are:
• The MOBICAT mobile primary jaw on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100-1,000 tph capacity
• The MOBIREX mobile primary impactor on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100 to 1,000 tph capacity
• The MOBIFOX mobile secondary crushing machines with feeding unit, impact crusher and a screen producing up to 3 grain sizes
• The MOBICONE mobile secondary crushing machines with feeding unit, cone crusher and a screen to produce up to 3 grain sizes, and
• The MOBISCREEN mobile screening machines, producing up to 4 grain sizes with fixed or swiveling discharge belts, with a screening surface dependent on ultimate use.
