BÖCK - The Company - We are the clamping people

BÖCK was established in 1978 and has evolved to become Europe`s leading company providing both silage clamps and silage covers.


BÖCK has been supporting farmers to produce premium quality silage through on-going field-tests, meaning our range of products have been tried and tested by the end user and fully consider the practical application required on farm. 


The BÖCK “Traunsteiner Silo” silage clamp system, is recognised by the farming community as the clamping method of choice. It is the best performing clamp design available for both livestock-farming and biogas (AD)-plants, ensuring maximum profits along with minimum losses.


BÖCK are the first company to support farmers with innovative cover material, like the underlay
film (starting in the early 1980`s), the GITTERflex® protection net (sold for more than 25 years now) and our unique, patented SiloClip® system, which offer unrivalled quality along with convenient handling.


Throughout the past we have developed a comprehensive network of retailing partners in more than 30  countries. Meaning BÖCK is fast becoming a worldwide trusted brand that trades on quality, expertise and service. Our customers from the agricultural sector and the Anaerobic Digestion sector turn to BÖCK for a one-stop-shop experience, benefiting by the combination of our product range and our support.


BÖCK understand that a satisfied customer will always be the best endorsement for our company’s philosophy: “Together we are strong”.

To maintain our position as a technological leader in silage storage, we work closely with scientists and researchers.

The BÖCK Silage Clamp

The unique design of the BÖCK silage clamp enables silage production of the highest quality, contributing to the improvement and success of your business.

Why is our silage clamp system so different to others?

  • To fill the clamp several tractors can drive in and out of the bay in simultaneously which saves compacting time. Remember, it is the compacting process that determines the speed of filling the bay, not the forage harvester!
  • Maximum compression with minimal expenditure is achieved via inclined walls. This enables easy and efficient compacting right up to the edges. By surcharging the clamp, the silage bay can contain an additional 35% of silage.
  • The earth bunds which form the side and intermediate walls of the clamp allow for safe and easy access to the covers. This also minimises any temperature fluctuations, ensuring your silage is consistently going to yield and performing to its optimum level.
  • The silage clamp can be adjusted at any time to handle growing silage requirements, by extending the clamp in length or by adding an additional bay.
  • Surface water and silage effluents are effectively separated. Leachate can be safely collected in a leachate tank without mixing with rainwater.




BÖCK Covering System

We understand that achieving the maximum output possible from your silage clamp is critical. Working closely with farmers around the world we have developed a range of products which minimise losses – these products make up the high performing BÖCK-silage-management. By using the BÖCK Covers you can improve the performance of your silage by up to 35% and save labour cost.

Why is the BÖCK covering system so effective?

  • We use the highest quality films and nettings that are proven to last.
  • Our covers protect your valuable silage which provides energy, protein, minerals and vitamins, delivering benefits to your livestock or AD plant and your bottom line.
  • By minimising oxygen penetration our covering system allows high quality fermentation and reduces surface spoilage.
  • We offer a number of labour-saving products including BÖCK SiloClip® and BÖCK SiloFix®
     to assist you in securing the covers – which are easier to use than those old tyres!


Our Service

We will help you determine the optimum dimensions for your silage clamp taking into consideration any site restrictions and the volume of silage required.

The BÖCK silage clamp system can be delivered as a complete set of parts with instructions for you to construct and assemble. Alternatively, we can recommend an approved partner to carry out these works. Our approved partners are experienced contractors and trained installers. Whichever route you choose, we will support you throughout the  process.

At BÖCK we will continue to support you after completion of your project, offering on-going advice on your clamp’s performance and BÖCK covering systems to enable your silage clamp to continue to produce only premium silage.

BÖCK Underlay Film

Premium quality for your silage

The BÖCK underlay film creates a suction effect, which prevents oxygen from penetrating straight through to the silage. It “sticks” to the silage surface and provides additional protection if there are small leaks in the silage film. The BÖCK underlay film is much more elastic than any other standard liner film, so it protects your silage even more effectively, giving you peace of mind.

BÖCK GITTERflex® Netting

Protecting your silage

Covering silage with car tyres used to be the standard, but since the revolutionary invention of BÖCK GITTERflex®, there is a much easier way of protecting your silage.
BÖCK GITTERflex® netting is simple to lay and protects the silage film against damage caused by cats, dogs, wild animals, birds and hail. It also prevents the sheets from flapping and forcing air into the silage.

That´s not all! Our BÖCK GITTERflex® makes handling easier:

  • The netting hangs down over the silage face, so the crop is kept well away from hungry birds.
  • Rainwater runs down the outside of the BÖCK GITTERflex®, protecting the exposed face of the silage.

BÖCK SiloClip®

Less manual handling

Covering silage is one of the most important tasks. As soon as the silage is brought in, it must be compacted and covered, ensuring the whole system is completely airtight.

After a hard day of ensiling, carting around vast numbers of gravel bags is not a particularly
appealing prospect. With an average silage bay measuring 30m x 8m, you would be looking at
moving around 1,8 Tonnes of gravel bags. With a 500kW biogas plant, that could be as much as 14 Tonnes.You know what this can do to your back!

Since the invention of the BÖCK SiloClip®, gravel bags are well and truly a thing of the past. The BÖCK SiloClip® has been proven on numerous silage systems over many years. Once you try the BÖCK SiloClip® you will wonder how you ever
managed without it.

We recommend attaching one BÖCk SiloClip® to the side wall of the silage bay every 1.1m. BÖCK Silage Clamp panels are delivered with all necessary anchor bolts.







 Keeping it in place


The perfect solution to safely and efficiently securing gravel bags on your silage clamp - improving the airtight seal of your covers and increasing silage quality.

The BÖCK SILOfix® system is a 20cm wide belt that is run across the clamp from left to right or front to rear, it’s very versatile!
At every 80cm/160cm along the belt a metal plate is attached, which is designed to fit the handle of your Bock gravel bags, the bags can then be hung in place. This allows the operator to use gravels bags safely and efficiently on any slope without having to worry about them rolling or slipping.

BÖCK SILOfix® comes with an eyelet at each end to secure to the clamp and comes in 4m increments to suit any size of clamp.
