... brakes from KNOTT.

A solid foundation with KNOTT

When the going gets tough
Building machinery is permanently subjected to extreme levels of material stress compared to any other type of vehicle. Added to the mechanical load is the permanent effect of dust, dirt, moisture and stone impact. For design reasons, brakes are often located close to the ground, exposing them to enormous degrees of stress.

A long life pays dividends
Service intervals for building machinery - and their brakes - must be as long as possible to cut maintenance stops to a minimum. Given the cost and time pressures acting on the industry, building contractors cannot afford to have construction machinery out of action for long periods. Brakes are required to go on working efficiently for as long as possible - which is where bespoke KNOTT brakes come into their own!

In the beginning was...
... the hydraulic servo brake for one of the first hydraulic wheeled excavators from Sennebogen. Which means the very first KNOTT building machinery brake dates back 45 years (spares are still available today).
