Auto-Lift Model “LS-C” OPERATION
SEPT/2004 (4945-7900) Section 2-1
Before operating this machine, read and
understand the Safety Section of this Manual.
BEFORE OPERATION
It is always good practice to become totally familiar
with the machines you are going to operate.
IMPROPER USE OF THIS MACHINE FOR
ANY TYPE OF OPERATION CAN CAUSE
SERIOUS INJURY OR DEATH.
BASIC DESCRIPTION
This machine can be run by
either one or two operators.
When DUAL Operation is
selected, two operators walk
alongside the machine and are
both required to actuate the
propel switch at the same time to
move the machine. This is done
so that the machine cannot be accidently
moved before the second operator has finished
working. When they have spotted the machine
over the rail section to be lifted, they release the
propel switch, press the cycle start button, and the
machine begins the work cycle. The work cycle is
as follows: first, the clamps come down and grasp
the rail; next, the lift cylinders come down and lift
the machine (and rail) to a predetermined height.
After the tie plate has been positioned under the
rail, both operators again depress the propel
switch; the lift cylinder retracts lowering the
machine. Then after the rail clamps open,
releasing the rail, the operators propel the machine
to the next tie and prepare to begin another cycle.
When SINGLE Operation is
selected, the operator must
select which side of the rail he or
she will be working. The side of
the machine that is active is
determined while standing at the logic box.
THIS MACHINE IS NOT EQUIPPED WITH
SEATS OR SEATBELTS. DO NOT RIDE
ON OR ALLOW OTHERS TO RIDE ON THIS
MACHINE WHEN WORKING, TRAVELLING,
OR TOWING. FAILURE TO COMPLY
COULD RESULT IN SEVERE PERSONAL
INJURY OR DEATH.
This machine is not designed for passengers
during work or travel operations. There are no
seats or seatbelts provided on this machine. DO
NOT RIDE ON THIS MACHINE!
HYDRAULIC SYSTEM
The Model “LS-C” hydraulic system uses a series
of manifolds. More detailed information regarding
the hydraulic system and manifolds is located
behind the tab marked “HYDRAULICS”.
The hydraulic pump is a pressure compensated,
variable displacement, radial piston type,
providing high flow and pressure. Refer to the
