Activation of platform
The accidental activation of the platform is prevented due to the dual control circuitry (2 switches need to be pressed and held simultaneously).
(1) Rope tension switches activate if any restriction is detected during platform descent eg objects in pit base.
(2) Photoelectric sensors detect the presence of objects protruding past platform edge during ascent (optional).
If any radio interference is detected, the transmitter and receiver will automatically switch radio channels (AS CAT III remote) or deactivate the platform (AS CAT II remote).
Two (2) alarms are activated when the hydraulic platform system is in use; an audible alarm and a flashing light.
All systems need to be operational for the platform to move.
