Standard and working principle of forklift electronic scale
An electronic forklift scale is a weighing gauge that weighs the loaded material during loading. The electronic forklift scale provides a cumulative value of the material being weighed and a printed list. The electronic forklift scale is an on-board weighing device integrated with the mechanical control part of the vehicle to achieve weighing in the vehicle travel. It is weighed by monitoring the predetermined weighing position with a proximity switch and converting the hydraulic pressure into the weight of the load in the bucket. It has two different working modes: target mode and accumulative mode. According to the operator's choice, the load can be automatically accumulated or deducted from the target set value.
Forklift electronic scale testing standards
The unit of measurement used for electronic forklift scales shall be grams (g) and kilograms (kg) tons (t). The accuracy level of the electronic forklift scale shall meet the requirements of the Y(b) scale according to the declaration of the manufacturer. The obvious parts such as the nameplate, face plate or meter head of the forklift electronic scale shall be marked with the measurement of the legal system mark and the measuring instrument. The mark, number and description shall be clearly identifiable, firm and reliable. The forklift electronic scale does not allow the user to adjust it himself.
Electronic forklift scale measurement requirements
1. Prototype packaging, appearance, nameplate, logo inspection
2. Check the various devices of the prototype to confirm that they are consistent with the documents provided by the applicant.
3. The nameplate, model specification, manufacturer, factory number, maximum weighing, minimum weighing, division value, accuracy grade level symbol, etc. should be marked on the nameplate.
4. Check the reliability of each numeric key, function key and its combination application according to the operation requirements of the product manual.
5. Technical indicators of the prototype under normal environmental conditions
Use and occasion of electronic forklift scale
1. The electronic forklift scale can automatically weigh the material while loading the material.
2. Widely used in the control of cargo loading in coal mines, ports, buildings and railway transportation.
Electronic forklift scale principle
The electronic forklift scale is based on two pressure sensors respectively installed on the oil inlet and return oil paths of the vehicle boom cylinder, and measures the cylinder pressure change during the lifting process of the vehicle boom, and adjusts the speed in the vehicle instrument. The central processor automatically calculates the weight data and displays the resulting weight on the meter screen. During the process of lifting the dump truck, the pressure sensor transmits the signal to the computer for data conversion processing; when the locomotive shovel the cargo, the boom immediately retracts to the starting position, and the forklift electronic scale immediately displays the weight of the cargo; when the locomotive is dumped, The screen shows the cumulative weight; when the bucket falls to the starting point, the screen shows the total weight of the goods.
