P.4 Kramer-Werke GmbH, a subsidiary of Wacker Neuson SE, is one of the leading manufacturers of all-wheel drive construction equipment that is marketed under the name of Kramer Allrad. Kramer loaders are known for their modern design and firstclass quality. To cope with increasing international demand for its products, in 2008 the company invested over 30 million Euro to build a brand new, state-of-the-art factory in Pfullendorf. The new production facility with an area under roof of 30,000 square meters was erected on a lot of 160,000 fist-size parts with a weight of around 1 kg up to components weighing 2 metric tons. Depending on the surface condition of the parts to be cleaned the speed of the monorail system can be adjusted from 0.8 – 2 m/minute. The blast chamber is equipped with eight (8) blast wheels, type Hurricane H 42. The blast wheel speed can be adjusted by frequency inverters which guarantees optimum blast results for any surface condition. The blast wheels are mounted in groups of four on each side of the blast chamber. They are slightly canted in and against the direction of the parts flow. This wheel arrangement guarantees that the front and back side of the parts is also exposed to the blast stream. To allow manual touch up after the blast process in the mono rail shot blast machine Rösler installed a manual blast room adjacent to the outlet vestibule of the RHBD. The system is completely encapsulated so that the noise level does not exceed 80 dB(A). Common blast media cleaning system reduces the cost by 30% The blast media used in the manual blast room is cleaned and re-circulated by the highly efficient media classification system of the monorail blast system. Compared to the installation of two independent recirculation and cleaning systems this combined blast media cleaning system costs 30% less. Another cost saving feature is the post filter system allowing the air from the dust collector to be so clean – free of dust – that it can be returned into the building resulting in significant energy savings. Tailor made monorail shot blast system based on a modular design Low operating cost with a high degree of flexibility The new manufacturing facility for compact 4-wheel-drive loaders and telescopic loaders at Kramer Company in Pfullendorf is one of the most modern factories in Europe. By selecting the continuous monorail hanger shot blast system RHBD-K Kramer is counting on the technical experience and know-how from Rösler. Rösler installs monorail hanger blast system in new production hall 20 blast wheels guarantee clean welding fabrications With the installation of a new continuous mono rail hanger blast system RHBD 35/35-K Rösler pursued two objectives: (1) it provides the urgently needed expansion of the in-house manufacturing capacity, and (2) the new blast system can be used for customer demonstrations and blast trials with large customer welding fabrications. square meters. The building is equipped with an integrated paint system, a high rack warehouse and an office wing. Adjacent to the new building is a demo area for equipment demonstrations. This super modern facility is also equipped with a Rösler continuous monorail hanger shot blast system RHBD 15/16-K for de-scaling and de-rusting of different components like castings, bent parts, forgings and welding fabrications prior to painting. The required surface finish is SA 2.5 or better. An existing equipment system adapted to the specific customer requirements An important point in the customer’s decision for this shot blast concept was that Rösler had already built multiple machines of this type and had proven that they can be modified to specific customer requirements. For example the 26 meter long system had to be fitted into the new building. The RHBD15/16-K blast system features an inlet and outlet vestibule allowing the blast cleaning of This 26 m long monorail blast cleaning system is utilized for de-scaling and de-rusting of different components like castings, bent parts, welding fabrications and forgings prior to painting This structural blast system located in the Rösler welding department expands the in-house production capacity and is available for blast trials with customer parts. Rösler designed this blast system for its own welding department in Untermerzbach. It allows the blast cleaning and pre-paint finish of welding fabrications with dimensions of up to 3.5 x 3.5 x 8.0 m (W x H x L) and weights of up to 15 metric tons. This structural blast system is equipped with twenty high performance Hurricane® 15 kW H 42 blast wheels. 2 sets of 2 x 5 blast wheels each are mounted on the left and right hand side of the blast chamber; one set located close to the entrance and one set located close to the exit of the blast chamber. The blast wheels are mounted at an angle of 45 degrees in and against the direction of the parts flow. This wheel arrangement allows the complete removal of welding slag, scale and rust from the front- and back-side as well the complete height of any welding fabrication irrespective of size and shape. The travel speed of the monorail system can be adjusted from 0.8 – 1 meter/minute. The blast cleaning process itself can take place with the parts transport system moving forward or reverse. For manual post cleaning of fabrications, especially housings with difficult to reach internal areas which may not have been cleaned 100% by the monorail system, a blast room with a compressed air blast system was installed behind the monorail shot blaster. Continuous and Batch Blasting in one System Parts to be blast cleaned are loaded into the blast system by a gantry crane equipped with multiple adjustable crane elements. Parts can be mounted onto different hanger positions. This allows the blast cleaning of multiple parts in one single pass through the machine. The monorail system is also equipped with a spinner (rotational device) which permits loading of of a batch of many small parts onto a fixture, transporting this fixture into the blast room and blasting the batch of parts while the fixture is rotating. 0t3g3499
