in brief:

1999, in response to strong demand from customers , DIGBITS built their first BAV Alligator Crusher attachment, the BAV3, for mini/midi diggers.
2005, DIGBITS produced their first tracked jaw crusher - the BAVTRAK micro, now superseded by the BAVTRAK 009.
2007, the BAVTRAK 025 mini tracked crusher is launched.
2008, BAV Crushers Limited is incorporated and takes over production of all BAV products in a purpose built facility.
2010, the BAV-CB range of crusher buckets is launched.
2012, the BAV-RS range of rotary screening buckets is launched.

What is a “BAV”?
We’re often asked what the name BAV means. The answer is fairly straightforward and relates to the initial model we began developing in 1998, the BAV3.

We have used CAD to design all BAV machines, the latest have been designed with SolidWorks 3D CAD and Cosmos FEA analysis, and the name derives simply from our early filing system:

Any project relating to buckets or excavator mounted attachments would carry a ‘B’ prefix.
The project name “alligator” was used from the start and this is where the letter ‘A’ comes from.
We ran numerous initial designs for our first crusher, but it was the third version which was the then prototyped, hence the ‘V3’ suffix.

Since 1998, we have added further models as required by customers, these new BAV series numbers had to fit in with the numbering system. In hindsight the numbering is no more or less logical than, for example, the system used by BMW for their cars, but it’s just the way it evolved.

When we began production of our self-propelled, rubber tracked, micro crushers in late 2004 (discontinued in 2012), we drew directly from the technology of our excavator mounted BAV Alligator Crushers and it was therefore logical to use the name BAVTRAK.
All our crusher jaws and boxes are fabricated in-house using the very best Hardox high-wear, high yield-strength steels for maximum durability.

Why use a BAV?
The BAV philosophy is to allow the recycling of waste brick, concrete and stone to be done on the most compact sites.
There are many reasons why our customers wanted to process on site, rather than use conventional approach of carting the waste away by skip or in grab loader lorrys:

Cost: Primary amongst these concerns is overall job cost, and this can broadly be described as the money paid to external contractors; skip hire, grab loaders, tippers, waste transfer etc. There are also hidden costs, like obtaining permits to park skips in certain areas, or the fact that if left overnight, a skip will often myseteriously fill itself, and the damage and nuisance which can be caused by vehicle movements.
Time: Customers often describe how jobs which could be done in a day (and should be if they are to turn in a profit) can be strung-out by transport delays. Waiting first for skip deliveries, then waiting for collections, and finally waiting for deliveries of hardcore into site can all add up.
Environment: There is increasing obligation - legally and morally - for industry to conserve natural resoursces and limit the amount of waste by-products. Gone are the days of tipping rubble into landfill, and now every possible bit should be recycled. Recycle on site and you can also reduce the environmental impact of vehicle movements to and from the job.
Space: Obviously at a premium on compact sites, but there are many definitions of compact. For a BAV micro or mini digger attachment might mean squeezing through a terraced property to work in a back yard, or perhaps even working inside a building. At the larger end of the scale, for a 50 tonne excavator with a BAV6, compact might mean doing the job of a large static crusher on half an acre.
Legislation: Direct taxes on quarried aggregates and on waste sent for landfill are steadily rising. Other ‘hidden’ taxes, such as fuel duty, road tax and congestion charges also tend to favour on site recycling. Now EU wide legislation is bringing changes to the way construction site waste must be dealt with. Initiatives such as the UK`s Site Waste Management Plans (SWMPs), introduced by DEFRA in 2008, are typical of the rapidly tightening requirement to recycle on site.
