English term

negative brake

English to Croatian Other Mechanics / Mech Engineering
Poštovane kolege,

Potreban mi je ovaj termin na hrvatskom jeziku, evo konteksta:

If there is an electric motor instead of a hydraulic motor (replacement of hydraulic motor with electric motor), the installer must provide for a load blocking system using a negative brake.

The negative brake must not be disassembled.

Failure to switch off the machine before carrying out any operations on it; Disassembly of the springs of the negative brake -> projection of objects.

If there is an electric motor instead of a hydraulic motor (replacement of hydraulic motor with electric motor), the installer must provide for a load blocking system using a negative brake.

Hvala svima!

Positive (active) brakes and the negative brakes

What is the difference between positive (active) brakes and the negative brakes?2014.02.24

Positive brakes are actuated by an external force. Negative brakes are actuated by the force of a spring and are released by an external force.

Example: Automobile brakes are positive brakes, actuated by applying foot pressure to a hydraulic piston which presses the brakes. Springs release the brake force.

Negative brakes work in reverse like elevator safety brakes are always closed and the braking force is applied by a spring. Hydraulic or electromagnetic pistons are used to to release the spring force thus releasing the brake.
