Solid achievement: Operating weight 7.7 tons
Speed: 30 km/h. Top class wheel loaders ...
Killing two birds with one stone: in this wheel loader a standard front axle has been combined with a dual circuit brake system plus parking brake at the front axle input. As a result the loader complies with US regulations governing building machinery.
... 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).
"Three-in-one" solution: Two hydraulic fixed caliper brakes as dual circuit service brakes and a spring applied - air released floating caliper as a parking and auxiliary brake for a wheel loader
