Axle load monitoring system, also know as on-board scales, digital weight gauges, axle load indicator or digital tonnage gauge.

    Will work with the following suspension types.

    • Air Suspension
    • Mechanical Suspension
    • Hydraulic Suspension

    There is a Kimax system to suit all applications including.

    • Trucks
    • Trailers
    • Forklifts

    The Gauge-Shop can install and calibrate a Kimax system to suit your individual needs.

    Air suspension

    How it works

    The axle load indicator (electronic scale) works by converting the air pressure in the truck and trailer air suspension into an on-the-ground weight. The air suspension will maintain the same vehicle ride height independent of the load. The ride height is maintained by changing the air pressure in the air suspension to support the load. The axle load indicator senses the smallest change in the air pressure and displays the weight of the axle/axle group within 1% of the vehicle's total weight, once calibrated.

    Air circuits can be deviated in a single circuit for one axle or dual circuits, one for the right side and one for the left side of the vehicle.

    Dual air circuits on an axle or an axle group offer you better accuracy in a shorter response time compared to a single air circuit on a similar axle.

    Mechanical suspension

    How it works

    Mechanical suspension in the form of parabolic springs is commonly used on the steering front axle of most truck brands.

    The SG sensor attached to the front axle senses the impact of the chassis weight, which is carried by the parabolic springs.

    In order to get accurate weights we recommend one SG sensor on each front axle.

    The Kimax 2 radio is tailored to match the specific combination of the suspension system and the specific number of axles you have on your truck.

    In this example you see two mechanical suspended front axles and two air suspended rear axles divided in left and right air circuit.

     Mechanical suspended rear axles can be arranged as individual single axles.

    or they can be arranges as a tandem axle group with parabolic springs

    or with trapez shaped springs

    Hydraulic suspension

    How it works

    Lowbed trailers for heavy load transport are often equipped with hydraulic suspension. Typical trailers have 4 or more axles. The axles can be grouped in one or more hydralic circuits.

    Each hydraulic circuit must be equipped with one hydraulic transmitter. The hydraulic transmitter must be located close to the lifting cylinders in order to achieve the best accuracy and the fastest response time.

    Hydraulic forklift 

    Most industrial forklift trucks are built up of one or more hydraulic cylinders for lifting forks.

    A simple method for measuring the weight of the load we carry on the forks, it is to measure the current oil pressure in the lift cylinder. The accuracy of this method may be expected to be 1 - 2% of max load the truck. 

    You get the best accuracy, when the hydraulic transmitter is installed close to the inlet for the lifting cylinder.

    Short distance between hydraulic transmitter and the inlet for the hydraulic cylinder, ensure you fast response time of the measurements and best accuracy.

    To reduce the influence of friction between the cylinder wall and the seals on the piston can have on the measurements, we recommend that forks first lifted above and subsequently lowered slowly to a certain height above the floor at each measurement.
