3.2 Safety
devices
With the design of the RBT the following safety devices have been installed, to reduce risks as much as
possible.
♦
The RBT is provided with an emergency stop button on the side of the control cabinet by which the
machine can be stopped immediately in case of an emergency. To release the emergency stop button
after operation, rotate the button.
The RBT can only be switched on if the centre rotating measuring rollers are pressed down, i.e. when
there is a vehicle axle in the roller brake tester (except when 3-wheel mode is selected).
♦
By applying the brake force and locking any wheels under test, the rollers will stop immediately.
♦
Closed covers for the chain and electrical components.
♦
The electrical circuits are built in the display cabinet, to reduce any direct danger.
♦
The RBT is ground wired to earth.
♦
Optional roller cover plates can be provided to close the mechanical unit when the brake tester is not in
use.
