What should be paid attention to when the construction of truck scale?

Matters needing attention in construction of truck scale

1. The form of truck balance foundation pit:

There are two kinds of foundation pit forms of truck scale, one is non-foundation pit and the other is shallow foundation pit. Shallow foundation pit refers to the installation method in which the truck scale is installed in the foundation pit, and the surface of the scale is level with the ground. The truck scale without foundation pit is installed above the ground, which can be frequently cleaned and does not accumulate water, and the cost is relatively cheap. Generally choose the installation method of truck scale without foundation pit.

2. Location:

The installation position of the truck scale should have good drainage channels, which will not be submerged by heavy rain or mountain torrent. For shallow foundation pit, drainage channels should be set up. In addition, the two ends of the truck scale must have a sufficient length of straight road for the car up and down the scale platform, both ends of the straight road should be at least equal to the length of the scale platform.

Another factor that affects where the weighing machine is installed is the number of cars you weigh each day. If you only weigh about 20 cars a day, - Taiwan truck scale should be enough, to set up a two-phase road weighing; If every day to balance about 50 cars, you need to prepare a parking place, - Taiwan truck balance should be enough, and then prepare - a side road; If there are far more than 100 cars per day, you should consider using two truck scales at the same time, each capable of weighing heavy or empty cars in both directions and with sidewalks.

You should consider: Where should the car be parked? Will there be a line for weighing? What happens when it snows, or rains heavily, or during peak season? And so on, all need you to take attention.

3. The basis:

The truck scale must be poured concrete foundation, this foundation must be excavated below the local permafrost line, in the construction should ensure the concrete label, casting embedded parts is to ensure the horizontal degree, position degree and other geometric dimensions, in the pouring of concrete to ensure that the embedded parts do not shift. After foundation pouring is completed, it should be maintained and mixed according to civil engineering specifications. The truck scale can not be installed until the concrete reaches the designed strength index. If you want to shorten the maintenance period, it is allowed to add "early strength agent" and other measures under the guidance of professional and technical personnel during construction. In order to protect against lightning, you should set the root ground pile according to the local conditions, and ensure the grounding resistance of 4 ohms, from the center position of the weighing platform to the weighing room should be laid -- root iron pipe, used to cross the signal cable.

4 pounds of room:

The weighing room should be close to the truck scale, so as to place the weighing instrument, or the computer, printer and other equipment. In addition, to ensure that the chief weighing officer can also communicate with the driver, the secretary of scale sheet, ensure that the car on the scale, identify the car 5. Installation and verification: after the installation and debugging of the truck scale, the Bureau of Metrology Supervision will verify it and issue a certificate of qualification before it is officially used
