Installation Method of Crane Electronic Crane Scale

1:Install the load cell under the balance bar shaft

This kind of structural transformation is relatively simple, but due to the small force ratio, the stability and accuracy of the metering performance are low, this is only selected when it is difficult to use other methods to transform the crane with low metering accuracy requirements or extra large tonnage. Program. After modification, the accuracy can reach about 1% F·S.

2:Install two sensors directly on both ends of the original pulley shaft

This is a common method when installing crane scales. The specific modification method is to remove the original U-shaped pallet and weld two small sensor installation platforms as the sensor installation base. After installing the sensor, press the fixed pulley shaft directly on the sensor, and there must be enough at both ends of the fixed pulley shaft. space. This structure needs to be modified on site. Due to the limited conditions, the level of the sensor installation base is difficult to guarantee, which affects the accuracy, and it is particularly difficult to maintain and repair in the future. This solution can only be used when the user is remodeling the vehicle.

3:Dynamic rail scale using rail-type load cell

The scheme is to select an appropriate position on the track of the trolley, cut off a section of the original track, and replace it with a track-type sensor. When the trolley passes the track sensor, it automatically performs dynamic weighing. Traditional track-type weighing is mostly static. Because it is difficult to accurately stay at the designated position in actual operation, the value of the driving is not high, which limits its use. Now the excellent dynamic technology can automatically weigh with high precision during the driving movement, without any influence on the driver's operation and driving performance, completely changing the range of adaptation of this method.

4:Fixed pulley measurement

The plan uses two side plates at both ends of the original fixed pulley block to be hung on a specially made force transmission shaft. The two ends of the force transmission shaft are press-mounted on two load cells on the trolley platform. This structure can guarantee The accuracy reaches the level of 0.5% FS. This kind of scale body structure is currently the most common form of application.
