3D – LPS Paving System



System Key Features and Advantages include:

  • Lowest cost entry point for a 3D paving system
  • System operates “indoors” or “outdoors”
  • System is open architecture i.e. transfer it between your fleet of machines  
  • LPS and GPS systems are a readily interchangeable “family” of 3D controls

Ligchine International has partnered with Topcon Positioning Systems to offer the revolutionary ‘3D LPS’ system (local positioning system) for Concrete Paving as a ScreedSaver option.  The combination of Ligchine’s boom operated ScreedSaver machines with Topcon’s “LPS system” guarantee you the lowest cost entry point into 3D paving; amazing ease of use; significant labor savings; high volume production; and world class accuracy whether operating indoors or outdoors.

This economical Topcon ‘LPS’ system utilizes an automatic tracking Robotic Total Station to register and maintain screed position from a machine mounted prism and sonic tracker. Height adjustments are transmitted to and from the screed at a rate of 20 times per second via radio signal to maintain accurate specifications on the defined jobsite plan. Since the LPS system does not require a GPS signal, it operates without limitations whether it is indoors, outdoors, or in areas with obstructed GPS satellite reception.

The Ligchine/Topcon LPS system is NOT a proprietary system.  The LPS 3D system has been engineered to control Ligchine ScreedSaver machines, but equally important, you can easily move it to your other concrete and/or earth moving equipment to maximize your return on investment.   

Already have, or looking to add mmGPS? Easily switch between LPS and mmGPS, or upgrade to mmGPS as each system shares many of the same Topcon hardware and software components resulting in maximum flexibility and cost effectiveness for your business.

Profitability and ROI (Return on Investment) are crucial in the ever-growing, multi-billion dollar industry of concrete overlays and paving. The versatile ScreedSaver machines that place concrete on grade, slope, dual slope and 3D contours will position you to grow your business in affordable steps into a wide variety of profitable opportunities and new markets.
