Q: WHY SHOULD I INVEST IN AN EZ~SCALE WEIGHING SYSTEM AS OPPOSED TO A COMPETITORS
SCALE?
A: Quite simply… ACCURACY
Ez~Scale for wheeled loaders is GUARANTEED to be the MOST ACCURATE
loader scale available in the world today for weighing while the
machine is on-the move. Only the Ez~Scale system advertises accuracy
of better than ½ of 1% accuracy.
Q: DOES THE USE OF AN EZ~SCALE INCREASE MY LOADING CYCLE TIME?
A: Competent loader operators report, that after operating their
loader with the Ez~Scale for approximately four hours, it does
not affect their cycle time.
The biggest reason is that the Ez~Scale system is designed to be
used while the machine is moving! Competitors weighing systems
state right in their operators manuals… For best accuracy… The
machine should be stationary, run at a certain RPM and hydraulic
oil should be warmed to operating temperature.
Q: DO I HAVE TO STOP MY MACHINE WHILE WEIGHING?
A: No
Dual transducers are standard equipment with the Ez~Scale, by using
two transducers in the hydraulic boom cylinder circuit and automatically
stopping the boom before measuring the oil pressure the operator
does not have to stop the machine to get accurate weighing while
on the move.
The reason is: One transducer is mounted in the base end circuit;
the other is mounted in the rod end circuit. When the Ez~Scale
automatically stops the boom in the hold or neutral position, the
oil is trapped on either side of the hoist cylinder piston and
the main control valve spool. When the loader hits a bump, the
load can be thrown up or down causing the pressure in the base
end of the cylinder to increase/decrease, however the pressure
in the rod end will increase/decrease and the Ez~Scale computer
will quickly analyze these readings and still display an accurate
weight.
Some major manufacturers of weighing systems that weigh without
stopping the boom recommend in their operators’ manual, that to
obtain accuracy the operator must ensure:
The loader is on level ground ~ Ez~Scale can operate on grades
up to 15%
The loader is stationary ~ Ez~Scale is designed to weigh with the
machine moving.
If the machine has been standing idle for more than 30 minutes
or has been used only occasionally over this period, the hydraulic
oil should be warmed up and the scale should not be used until
hydraulic oil is at normal operating temperature. Because the oil
just pushes against the Ez~Scale transducer, as opposed to moving
in the system, which causes pressure changes while weighing, hydraulic
oil temperature is not critical to Ez~Scale ‘s accuracy.
The load is to be raised smoothly through the trigger point at
about half engine RPM ~ Ez~Scale can be used at any RPM selected
by the operator when zeroing the scale.
Do not allow the machine to rock while it lifts; Ez~Scale generally
weighs while the machine is in reverse backing out of the pile,
the hoist lever automatically kicks into the hold position, at
a safe load and carry height, allowing the operator to see over
the top of the bucket as you are approaching the truck and because
of the dual transducers and trapping of the oil, rocking the machine
is not critical.
Note: The reason for these procedures is because the hydraulic
oil is moving past the transducer while weighing and hydraulic
pressure is caused by restriction to flow.
Q: WILL THE EZ~SCALE WORK ON MACHINES EQUIPPED WITH RIDE CONTROL?
A: Yes
Provided the ride control is working correctly, this option can be switched
off either automatically or manually during truck loading. The Ez~Scale generally
completes its’ weighing while the machine is backing out of the pile so the
ride
control does not come into play. We have Ez~Scale’s installed and working
on makes & models from 1995 to present that don’t interfere with accurate results.
Q: HOW LONG DOES IT TAKE TO INSTALL THE EZ~SCALE WEIGHING SYSTEM?
A: Approximately 1 day to install and 1/2 a day to calibrate and
train the operator.
This includes installation, calibration & operator training, providing the customer has prepared the machine as per the
pre-installation instructions, has an operator, legal weighbridge
and a truck available, for testing.
Q: IF I TRADE IN MY MACHINE OR IT IS TAKEN TO ANOTHER LOCATION
CAN I REMOVE THE SCALE & INSTALL IT ON ANOTHER MACHINE?
A: Yes, this is a major advantage of an after market weighing system.
This has been done numerous times. It takes approximately two days
to remove refurbish and reinstall the Ez~Scale system on another
machine.
Q: ARE THERE ANY FURTHER BENEFITS TO USING AN EZ~SCALE WEIGHING SYSTEM?
A: Yes, there are numerous benefits available.
Some Examples…
USB Date Logging
Ticket Printer
Allows the loader operator to download/print a ticket that shows
the TARGET weight, total loaded and the number of lifts to achieve
total weight. The downloaded/printed ticket also identifies the
product & customer, the date, time, operator, unit and location.
This is a useful tool to resolve any dispute between the loader
operator & truck driver at the weigh bridge The printer can be set to automatically print
a ticket at the end of the loading cycle for every load or just
when required.
This is also a useful management tool to track productivity of
each of your individual loaders, operators and locations.
