Only a few more days now. The MOTEK, the world's leading trade fair for the automation of production and assembly opens its gates once again from 9 - 12 October in Stuttgart). We would be delighted to meet you at our trade fair booth. You can find us here:
Hoist gears are real all-rounders in drive technology. Hardly an application case where they are not as a driving element under the discussion. We manufacture hoist gears since 1945. The basic principle is simple and brilliant at the same time: A rotary motion is simply converted into an axial movement – and this is in extremely small space.
When the body is assembled together with the engine in the production line manufacture of cars, the experts speak of a "wedding". It is precisely at this point that the linear chain from Grob Antriebstechnik plays a very important role at a premium car manufacturer that produces in England.
The co-operation between our English representative for linear chains - R A Rodriguez (UK) Ltd - with a custom machine manufacturer gave rise to a solution.
Mr. Schmalzhaf, where do you think the company's strengths lie?
I think our strengths lie mainly in the high service orientation and the short reaction times. Thanks to our large spare parts warehouse we are able to produce ready-to-use lifting elements overnight. Apart from that I'm always pleased to see the motivated and friendly sales team.
Mobile systems always have to be lubricated. That also applies to the linear chain, which has long since become an indispensable component of linear drive technology.
Until now we have specified the lubrication interval in the operating instructions. It was the customer's responsibility to observe these prescribed service intervals.
What seems like a contradiction at first glance is, on closer examination, an ingenious solution in linear drive technology. There, materials are shifted, machines positioned, platforms moved and goods put into storage and taken out again – to put it simply: linear movements are called for. The "linear chain" from Grob GmbH Antriebstechnik is the technological basis here for continually fresh ideas for solving linear movements, cleverly, in a space-saving manner and inexpensively.
The following problems occurred in the assembly line production at a car manufacturer: the cable harnesses are delivered by the manufacturer in plastic bags. That is not a problem in summer, but in winter when temperatures are cold the following happens: when the cable harnesses are unpacked and installed, some of the components can break. The cable harnesses are then useless. This leads to production bottlenecks and increased costs.
When aluminium cylinder blocks are cast, thermal stresses can occur within the material during cooling. These stresses can be relieved during the subsequent machining and lead to dimensional deviations. In order to dissipate these stresses, many manufacturers carry out a thermal pre-treatment in a heating furnace prior to machining. In this way the stress is dissipated and the risk of dimensional deviations during machining is reduced.
Anyone who has ever been to the theatre knows that the scenery is changed or rearranged during the intermissions. When you return after the intermission there's a different stage setting. It's much the same in film studios.
Grob GmbH Antriebstechnik was still just a small handicrafts company when Prince Charles officially put the Anglo-Australian reflecting telescope AAT into operation in the observatory on Siding Spring Mountain in Australia on 16 October 1974. The reflecting telescope installed there was one of the first telescopes in the southern hemisphere and at that time the largest in Australia with a mirror diameter of 3.9 metres.
