WLS555 Loader Scale Demo Key Features:

wls555 Overview youtube video:

This picture below is an SCI Scale Controller-I/O Module being installed on the front nose of a Cat 980G wheel loader.  The cover plate was removed and the SCI Controller was installed inside the compartment. All of our electronics are weatherproof IP67 Rated. The Scale Controller has an installed WiFi chip that communicates with the 8 inch WiFi Rugged Tablet and optional WiFi printer inside the cab.  This eliminates the need to run any cables into the cab from the controller.  This saves installation time & hassles.

WLS555 Weigh On The Move
​Articulated Loader scales:

The WLS555 provides users with start of the art technology.  Our system has a .1% failure rate on the components, you can count on its reliability.

We offer 7 days a week technical phone support to assist you with all aspects of the scale setup and long term operation.  This is done at no charge to you for our support, for the life of the scale.  On average it will take you 4 to 6 hours to install and calibrate the scale.  On a recent system installation on a Cat 966M the customer experienced a .5% error on the system calibration.  We advertise as standard a 1% error rate on the machine static tipping load capacity.  Another customer had a John Deere 644J and a Cat 950K, this customer had a 60 lb error on each machine when calibrated, which is a .2% error on machine capacity.

The WLS system is feature rich, for those users that want a basic weigh on the move scale scale, they simply leave the more advanced features turned off.  For those that want more of the advanced features, you can turn features on and off with the slide of a button.  The system ships as standard with the Rugged, Commercial 10" Tablet (waterproof, shockproof, dustproof), it can also ship with a Tab A7 Lite or users can use their own Android Smart Phone or Tablet.
What size of machine is the scale designed to work on: We have customers with skids steers on up to the largest articulating loaders in the market using the WLS555 Scale.  Our smaller size customers load 10-15 trucks of material a day, our bigger customers typically load 750+ trucks a day.
