7.14. Centrifugal emergency brake activation
The platform is equipped with an anti-fall emergency device. The system consists of a centrifugal
brake, calibered to activate at a descent speed greater than the movement speed of the platform
(overspeed). In case of activation, the brake blocks the platform from any vertical movement and
triggers the safety line. This cuts off the power supplyto the motors and activates the engine
brakes.
In case of activation:
•
Plug the derivation adaptor ( RD-7243-BE-112 ) to the main control panel ( CC1 ) to bypass the
safety line and allow limited operation of the platform.
Note:
In this mode, the platform cannot descend, as only the " HAUT/UP" coontrol works.
Press and maintain the " HAUT/UP" control on the operator control box to elevate the
platform. Elevation of the platform only works for 5 seconds. Beyond this delay, the platform
automatically stops rising and the "
HAUT/UP" control must be pressed again.
•
Rise the unit by about 1ft (0,3m) to free the brake.
•
Lower unit to the ground using the emergency descent procedure Important! Alternate the
pressure on the second lever to limit acceleration.
