The brake system onboard a vehicle is vital for the safety of the vehicle. It is therefore important that the design of the vehicle and the design of the brake system are co-ordinated to give the optimal safety and good performance and that complements other modern cab ergonomics to reduce operator fatigue and give good machine feel.
The valves may be used in open centre, closed centre and load sense hydraulic systems.
The high flow capability of the valve permit use with wet brakes, which typically require more flow for actuation.
Reduced mechanical drag and power loss by allowing the wet brake discs to be further apart when not applied.
A wide range of actuating forces can be specified, including stagemodulating springs for more progressive feel.
A floor-mounted pedal is available in a range of pre-set angles, with optional heel plates.
The valve may be mounted vertically or horizontally beneath the pedal.
Actuation
Safety Locks are held open by hydraulic (100 bar min) or pneumatic (3,5 bar min) mean and clamp when pressure drops.
Direction of load
In most applications Safey Locks are mounted on a baseplate, so that the load causes a compressive force to the mounting surface. But if the application requires an upward absorption of the load, a flange for attachment is required as well as a special design of the Safety Lock housing regarding the tensile load.
Hydraulic super-heavy load clamping:
The Clamping Element with membrane technology KW
The KW series is a hydraulically operated heavy load clamping device. The hydraulic oil presses the large-surface contact sections directly onto the section rail guide via a piston mechanism. A pre-tensioned reset spring enables short cycle times.
The pressure ranges from 20 bar to a 100 bar maximum for sizes 25 and 30. All sizes from 35 to 125 operate in a pressure range from 30 bar to a 150 bar maximum. The KW series features zero backlash and extremely low absorption volumes of maximum 7.6 cm3 per clamping operation.
The KWH/ KBH construction series is a hydraulically operated heavy load clamping/ braking device. The hydraulic oil pressurizes the large-surface contact sections directly onto the guide rail via a piston mechanism. A pre-tensioned reset spring enables short cycle times. The special diaphragm technology guarantees leak-free performance. The pressure ranges from 20 bar to a 100 bar maximum for sizes 25 and 30. All sizes from 35 to 65 operate at a pressure range from 30 bar to a maximum of 150 bar. The KW series features zero backlash and extremely low absorption volumes of maximum 3.8 ccm per clamping operation.
