Lifting column
The lifting column consists of:
• Aluminium section
• Column brushes
• Linear ball screw
• Ball nut (with integral ball bearings)
• Trolley
• Bearing race
• Motor coupling
• Contact for battery current
• Aluminium battery holder
• Fastening knob with lock-screw
The motor transfers power to the ball screw via
the motor coupling. A ball nut runs along the ball
screw. The trolley is attached to this ball nut, and
the lifting arm is attaced to the trolley. When the
motor turns the ball screw via the coupling, the
ball screw moves the ball nut plus trolley upwards
or downwards. There are tracks in the aluminium
section for the wheels on the trolley to follow. The
ball screw is factory-lubricated and requires no
further lubrication. It is protected from dirt by two
column wiper-brushes.
Battery holder and batteries
The battery pack is placed in a special alumi-
nium holder on the lifting column. See also the
instructions for the charger. Only use original
Molift Batteries for Molift lifters.
Operating handle
The height of the operating handle (which con-
sists of a curved steel tube) can be adjusted by
means of a special bolt and knob so as to suit dif-
ferent users.
Hand control
The hand control has two buttons, for operating
the lifter ‘up’ and ‘down’. There is also a LED light
which indicates when the batteries needs char-
ging. If the diode lights up when the lifter is being
operated, the battery needs charging. But there
will still be sufficient remaining battery capacity
for 1-3 normal lifts of 75 kg and there will always
be sufficient remaining current for lowering the
patient.
