Mechanical Systems
•
Because of a wiring problem. Check the wiring from tape switch assembly to the main
circuit board.
•
Because the Microswitch is malfunctioning. Replace the switch or re-align it.
4.
The lift traverses poorly at specific points in the track system
Identify the points of blockage:
•
Is the blockage at the seam of two pieces of track? Correct the vertical and/or
horizontal alignment.
•
Is the blockage in a curved section? Check the curve for clearance. Curve walls
sometimes collapse in the bending process. Replace an improperly bent curve or try to
correct it using a track bending tool.
•
Is the blockage in a turntable? Check the vertical and/or horizontal alignment of
turntable and track. Brackets should be used to “force” permanent proper alignment.
•
Clean inside of track with alcohol
5.
The lift does not power traverse well anywhere along the track
Open up the lift and check the alignment of the traversing system. There should be little
noise in the gears and minimal sway in the motor bracket when the motor is running.
Ensuring that the motor is tightly fastened and the gears are mounted securely, aligned
with each other can eliminate “Laboured noise and excessive sway”.
6.
The lift motor seems to be running, but does not work in UP or DOWN direction.
The motor output shaft or worm wheel of the motor may have worn out. The acceleration
activated the overspeed governor, which is designed to prevent further use until the lift has
been repaired. (The overspeed governor is a universal, failsafe mechanical brake, which is
triggered by centrifugal force and functions independently of the lift’s pneumatic electro
-
mechanical system.) The motor will need to be replaced.
