#CMT# #/CMT# The lift (1) has a physical magnitude sensor (74) connected at an angle (alpha), by a bijective function, between a forward displacement direction of a frame (2) and a forward travelling direction (F-MA) integrated to a controlling console (70). The direction (F-MA) is corrected with the displacement direction when the angle is null. An electronic programmable control unit (72) controls a motor (4) to displace the frame in forward and reverse directions (F-AV, F-AR) when a measured magnitude corresponds to an angle ranging between 3pi/ 2 and pi/ 2, and pi/ 2 and 3pi/ 2 radians, respectively. #CMT# : #/CMT# Independent claims are also included for the following: (1) a method of controlling an aerial lift (2) an information recording medium comprising instructions to perform a method of controlling an aerial lift. #CMT#USE : #/CMT# Aerial lift. #CMT#ADVANTAGE : #/CMT# The construction of the lift reduces linear displacement speed of the frame when the measured magnitude of the frame corresponds to the angle ranging between pi/ 2 and 3pi/ 2 radians, thus permitting the usage of the lift, in a safe manner. The measured magnitude serves to fix the displacement speed of the frame, thus simplifying a man-machine interface of the controlling console. The construction of the lift eliminates the validation of the displacement control when the measured magnitude of the frame corresponds to an angle ranging between zero and pi radians, thus simplifying the controlling of the lift. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of an aerial lift. alpha : Angle F-AR : Reverse direction F-AV : Forward direction F-MA : Forward traveling direction 1 : Aerial lift 2 : Frame 4 : Motor 70 : Controlling console 72 : Electronic programmable control unit 74 : Sensor. |
