G-CAR 4.0

  • COMES G-Car 4.0 is a computerized CCD instrument for checking wheel and axle alignment of vehicles with dmc up to 3.5t. The device makes it possible to measure passenger cars and light trucks. The device has 4 measuring heads: 2 active heads and 2 passive heads. The active heads use measurement technology based on, among other things, 4 CCD cameras. Communication of the heads with the computer and powering the heads is done wirelessly. COMES G-Car 4.0 is a device that performs measurements relative to the geometric axis of vehicle travel. It is possible to upgrade the G-Car 4.0 device to the G-Car 8.0 version. The device is certified for use at Vehicle Inspection Stations. COMES G-Car 4.0 is a device designed and manufactured in Poland.

    • Complete computerized CCD device for wheel and axle geometry measurements of vehicles up to 3.5t dmc.
    • Measuring heads equipped with, among others, electronic biaxial inclinometers for measuring vertical angles and high-resolution CCD sensors/cameras for measuring vehicle horizontal angles.
    • Rechargeable (wireless) power supply for measuring units.
    • Wireless radio communication between the measurement units and the central unit.
    • Wheel mounts for mounting on rims with diameters ranging from 11′” to 25″.
    • Intuitive measurement program on PC, guiding the operator step by step and:
      • displaying the entire measurement and adjustment process on the screens, showing the measured parameters in real time,
      • creating measurement reports and allowing for the archiving of measurement results,
      • presenting the results in a tabular and graphical manner, showing the vehicle’s wheel and axle alignment in a clear way,
      • generating a measurement protocol that includes customer and vehicle data, factory data, as well as data before and after adjustment,
      • with a choice of 3 operating modes, allowing to optimize working time and configure the measurement activities to the needs of the operator,
      • having a function of toe adjustment with the wheels twisted and unloaded (lifted),
      • having an extensive database compatible with Auto-Data.
    • Wheel run-out compensation is carried out by rotating the raised wheels.
    • High practicality of the device through the possibility of using a portable laptop computer, which provides visualization of measurement results anywhere in the vicinity of the tested vehicle.
    • Mobile cabinet that allows easy movement of the device.
    • Measuring heads with an ergonomic handle for easy installation and handling.
    • Ability to measure vehicles with a wheelbase of up to 5 meters.
    • Possibility of using an extension for the monitor.
    • Possibility of using the device both on a pit stand and a diagnostic lift, in a workshop or a Vehicle Inspection Station.

    The G-Car 4.0 device has the same measurement capabilities as the G-Car 8.0. The difference is that in the case of the G-Car 8.0, the measurement of all measured parameters takes place simultaneously, while for the G-Car 4.0, the rear axle is measured and adjusted first, and only then the front axle is measured and adjusted. In addition, the measurement time for the G-Car 8.0 version is shorter than for the G-Car 4.0.

    It is possible to upgrade the G-Car 4.0 to the G-Car 8.0 version, which is a very practical yet unique solution.

    COMES G-Car 8.0 is a device designed and manufactured in Poland.

    The device has an ITS certificate (No. Z15/028/17), which confirms the possibility of using the device at the VIS.

    The G-Car 4.0 device allows measurement of the following parameters:

    • total toe
    • individual wheel alignment
    • toe difference
    • camber angle
    • camber difference
    • camber angle of the steering knuckle axle of the front axle
    • angle of advance of the steering knuckle axle of the front axle
    • front axle steering angle difference
    • maximum steering angle of the wheels of the front axle
    • deviation of the geometric axis of travel from the axis of symmetry / wheel tracking
    • longitudinal wheel offset of the front and rear axles
    • lateral offset of wheels for left and right sides
    • axle misalignment / vehicle wheelbase difference
