Ergonomic solutions improve workplace safety

An Applied Automation, Maytec Division product story

The production engineers at Kautex have produced a set of company standards based on Textron Automotive's Humantec manual.

Health and Safety in the workplace is one key issue all managers are aware of, whether they are risk assessing the office for trip hazards and RSI or categorising a machine based on the severity of injury and frequency of access, the application of certain rules is key to assuring they meet the required standards.

Kautex Textron CVS in South Wales has gone one step further by being pro-active and improving its work efficiencies by applying ergonomic solutions.

The production engineers at Kautex have produced a set of company standards based on Textron Automotive's Humantec manual.

One key reason for the development of the manual was as a guide to achieving a high-performance workplace through ergonomics.

Kautex manufactures sub-components for the automotive industry with products ranging from windscreen washer bottles to telescopic headlight wash systems.

The assembly process for these products requires a high proportion of manual assembly and therefore the company has in excess of 80 assembly benches.

The Humantec manual dates back to 1997 and it addresses many aspects including the layout of an office desk, the position of the computer screen in relation to the user and the setup of the operators chair.

It also includes the use of assembly benches.

Kautex teamed up with aluminium profile supplier and solution provider Applied Automation (MayTec division) in order to deploy suitable ergonomic solutions throughout its South Wales facility.

David Rowe, Managing Director at Applied Automation (UK) , said "There is no such thing as a British Standard person; therefore it makes sense that any assembly bench height should be adjustable".

"Using the MayTec aluminium profile we can produce simple and cost-effective solutions to accommodate such demands, and produce an assembly bench which is ergonomically suitable for both little Betty and big Fred".

Paul McAndrew Manufacturing Engineering Manager at Kautex said "The original 'adjustable' solution used within the production department, involved cutting the legs on the static assembly bench and fixing telescopic extensions to the legs, thus allowing the bench to move up and down, while maintaining rigidity".

"The adjustment mechanism was a bottle jack placed in the middle of the underside of the bench, by raising the jack, it raised the bench".

"Whilst basic it was very effective, though not ideal" he said.

On a mission to find the ideal solution to meet their demands for health and safety the production engineers spoke to a number of aluminium profile suppliers including Bosch, MBS item and Applied Automation - MayTec division.

The engineering application team at Applied Automation, headed by Nigel Williams, proposed a solution which incorporated the MayTec profile system and a hydraulic pack consisting of four hydraulic cylinders and a manual rotary handle for adjustment.

This solution allows for 200mm of travel from the lowest bench height to the highest.

McAndrew at Kautex said "The assembly operators understand it is their responsibility to adjust the bench to meet their individual requirements, and they often adjust the bench height during the working day as their needs change, just like you would alter the lumber support in your car seat, if you were driving for a long time".

An additional benefit in using the aluminium frame in place of the old fabricated solution is the ease of adding accessories to the bench such as cable reels, storage bins and heat gun holders; this is due to the "T" slots on the profile.

The MayTec solution makes for a flexible and adaptable work suite and enables personalisation to both the operator and or to the operation.

Steve Brown, Kautex' Environment, Health and Safety Manager said "We are currently 40% way through the migration of their work stations, assembly benches and packing tables from the old fabricated solution to MayTec, and are so pleased with this approach we present and promote the solution at our inter-company safety and production seminars".
