Autoquip SPIRALIFT SCISSORS LIFT - Manual (Page 18)

18
It is mandatory that all authorized maintenance and installation personnel become
completely familiar with the contents of this manual before working on the Spiralift™.
The following instructions were written to ensure safe and reliable operation of the lift. If
the Spiralift™ is not maintained according to the instructions given in this manual, the
warranty may become void by Autoquip.
The Spiralift™ power unit is a very durable and dependable precision mechanism. It
will give many years of trouble-free service if taken care of properly. It should be
treated the same as any precision instrument.
The upward and downward movement of the platform must not be restricted during
operation of the Spiralift™ scissor table. The spiral mechanism is designed to “stack”
under compression. If this compressive force is not maintained, the spiral may
“unstack” and cause immediate and irreversible damage to the spiral mechanism.
WARNING!
When extended, the spiral column is held in compression by the weight of
the lift platform. NEVER remove this compression! To do so can result in
irreversible damage to the spiral mechanism.
When the “UP” button is pressed, the coil of the motor starter will close the line contact
permitting 3-phase electrical power to be applied to the motor. The rotating motor shaft
is mechanically coupled to a gear reducer. The gear reducer has an output shaft with a
belt drive system tied to the spiral mechanism. As the motor rotates, the spiral
mechanism turns and “builds” a spiral column that raises the lift platform from beneath
until the power is shut off by either releasing the “DOWN” button or until the lift makes
contact with the “UP” limit switch. .
Pressing the “DOWN” button will cause the reversing motor starter to engage and start
the motor. The gear reducer and belt drive system now turn the spiral mechanism in
the opposite direction, thereby “un-building” the spiral column causing the lift platform to
lower until the power is shut off by releasing the “DOWN” button or until the lift makes
contact with the “DOWN” limit switch.
WARNING!
NEVER stand, sit or ride on the lift!
