What are the precautions for the installation of electronic truck scale?

For the truck scale without foundation pit, the foundation supporting the truck scale should be 50mm above the ground, in order to prevent the ground water flow and quicksand into the truck scale foundation corrosion foundation plate, anchor bolts and weighing sensor connector, resulting in the service life of these steel components shorten and increase the maintenance cost and frequency of the truck scale. The foundation surface of the foundation should have a certain lateral slope (high in the middle, low at both ends, the slope is 1%), so that rainwater flow out of the foundation. For truck scale with foundation pit, reasonable waterproof, anti-quicksand and drainage facilities should be designed to support truck scale foundation. Base plate is the steel components support truck scale, truck scale, through the base plate connected with the concrete foundation, base usually have 2 boards, points on the base plate and the lower base board, the two boards together under the weighing sensor fittings for longitudinal and lateral displacement, to ensure that the weighing sensor location in the correct position. The base plate is the component that installs and fixes the connection piece under the weighing sensor. The lower foundation plate is the component for installing and fixing the upper foundation plate and supporting the truck scale. The lower foundation plate is an embedded part. Two times of concrete pouring should be used to ensure that the horizontal height difference of each foundation plate is within 3mm and ensure the level of each foundation plate. Otherwise, if the level difference of each base plate is too large, it is difficult to balance the force of each weighing sensor during debugging; If the base plate is not horizontal, the force line of the weighing sensor will deviate from its axis and easily make it rotate along the axis. The force of weighing sensor is not balanced, so that the force of some weighing sensor is too large or too small, too large will shorten the service life of weighing sensor, but also make the linear error of automobile scale measurement performance is not good. When the force line deviates from the axis of the weighing sensor, the linear error of its measurement performance will become larger, and it is easy to cause fatigue damage, especially for the rocking column weighing sensor with a shrinking neck. In use, if the weighing sensor rotates along the axis, it will make the stability of the measurement performance of the truck is not good. The installation position of the base plate should be initially located according to the size requirements of the truck scale installation drawings.
