    Topcon’s new concrete paving system uses ‘millimeter GPS technology’

    ZPS_Topcon_Field-WTopcon Positioning Group has launched a new system for automated concrete paving — the ZPS system — with the new Z-Robot and Z-Stack sensor.

    Using enhanced Topcon “millimeter GPS technology,” the ZPS system is designed to bring unmatched accuracy to concrete paving with a fraction of the hardware required for a traditional local positioning system.

    The new Z-Robot is an advanced robotic total station with integrated Z-beam laser technology. The Z-Robot is designed to provide a hybrid function of high-precision, optically based vertical accuracy control and the convenience of Z-beam laser positioning to maintain that accuracy across the paver.

    “The ZPS system’s self-leveling Z-Robot cuts setup time in half compared with previous concrete paving methods,” said Murray Lodge, senior vice president and general manager of the Construction Business Unit. “With traditional systems, you need multiple, expensive robotic total stations to control the paver at any given time and at least another complete set of instruments for downrange transition. With the ZPS system, only one Z-Robot controls the paver — increasing productivity and profitability, and dramatically lowering the cost of the solution compared to LPS.”

    ZPS_concretepaving-Topcon-WOn board the paver, the ZPS system uses the new Topcon Z-Stack modular-designed system that seamlessly integrates GPS, optical targeting, and Z-beam reception into one unit by interlocking the required sensing technologies in one rugged “stack.”

    “The Z-Stack sensor is revolutionary,” said Lodge. “It combines time-proven Topcon positioning technologies into one multifunctional, consolidated and complete system that provides better accuracies and more efficient paving than ever before. The system requires no separate base station and only one cable needed for power and connectivity.

    “The system also offers a wider working area, with a range of up to 150 more feet than with traditional methods — minimizing instrument transitions,” Lodge said.

  • Topcon announces robotic-based system for concrete paving

    Topcon Positioning Group is offering a local positioning system (LPS) for concrete paving. The LPS Paving System is designed to provide a stringless paving solution in conditions when GNSS signals are blocked or unavailable.

    It uses multiple Topcon PS series robotic total stations — tracking two prisms mounted to the concrete paver — for steering and elevation control.

    “This robotic-based system does not encounter sensor outages from bridges and tight paving lanes, including sound walls and active traffic on a mainline project, which could be a problem using GPS,” said Brian Lingobardo, Topcon­ 3D road construction systems manager.

    The LPS system uses the new MC-i4 receiver with LongLink for local communications between the robots.

    “Multiple robots can be setup ahead of time for seamless transitions and without the need to stop to switch total stations. Often a contractor needs to minimize stoppage to achieve tight ride specifications on projects such as tollways,” Lingobardo said.

    “The robots provide very accurate data to the paver’s control system and in turn the results are very impressive,” said Lingobardo.
