The tower crane is a fixed Crane and has to be mounted On-Site. The Tower Crane presents itself like a vertical metallic structure having a horizontal boom that can turn over an angle up to 360°. From his particular set up, the tower crane is ideal for all king of a high building or high structure construction.
Tower crane includes Hammerhead Tower Crane, Flat Top Tower Crane, luffing type tower crane. Derrick Crane is installed on a stationary foundation.

2. If the user uses the heat tracing circuit by himself, non-magnetic materials such as copper tubes must be used. Heating temperature is determined according to the medium condition;
3, the installation of the magnetic flip level gauge must be vertical, the magnetic flap level gauge and the container lead should be equipped with ball valve, easy maintenance and cleaning;
4, the medium should not contain solid impurities or magnetic substances, so as not to cause jamming of the float;
5ã€Before use, the ball below the zero position should be set to red with a calibrated magnet, and other balls should be set to white.
6. Open the bottom flange and install the magnetic floater (Note: The heavy end with magnetic end up, can not flip.);
7. When debugging, open the upper pilot valve first, and then slowly open the lower valve to allow the medium to enter the main duct smoothly (the medium should avoid rapid impact of the medium on the float, causing fluctuations in the float series and affect the accuracy of the display). Observe the magnetic red and white balls. Whether the flip is normal, and then close the lower lead valve, open the drain valve, so that the main catheter level drops, according to this method three times, it is normal, you can put into operation (except for corrosive and other special liquids);
8, should be based on the media, from time to time cleaning the main catheter to remove impurities;
9. For level gauges exceeding a certain length (normal type> 3 meters, anti-corrosion type> 2 meters), it is necessary to add an intermediate reinforcement flange or ear climbing for fixed support to increase the strength and overcome its own weight;
10ã€
The installation position of the magnetic flip plate liquid level gauge should avoid or keep away from the material media entrance and exit, avoid the rapid change of the local area of ​​the material fluid, and affect the accuracy of the liquid level measurement;
11. The level gauge installation must be vertical to ensure that the float assembly moves freely up and down within the main body tube.
12. The proximity of the gauge body around the body of the gauge does not allow direct proximity of the magnetizer or directly affect the accuracy of the level gauge.
13. After installation of the level gauge, it is necessary to use magnetic steel for correction. The guide for the column is displayed once so that the red below the zero position is displayed in red, and the position above the zero position is displayed in white.
14,
When the liquid level gauge is put into operation, the liquid inlet valve should be opened first to allow the liquid medium to enter the main body tube smoothly, so as to prevent the liquid medium from rising rapidly with the floating ball assembly, causing the turning column to malfunction and turn over. If this phenomenon occurs, the magnetic steel can be used to recalibrate after the liquid level is stable.
15. In order to prevent damage to the float assembly during transportation, the float assembly is removed from the main body of the liquid level gauge before leaving the factory. After the level gauge is installed, the bottom drain flange is opened and the float assembly is reinstalled. Into the main tube, pay attention to the weight of the floating ball assembly upwards, can not flip. If the float ball assembly has been installed in the main body tube at the factory, in order to ensure that the float ball assembly is not damaged during transportation, we use the soft card to fix the float ball assembly in the main body tube, and only need to pull the soft card out during installation.
16, according to the media, can be found regularly to open the sewage flange to clean the main pipe precipitation material
Magnetic level gauge installation and maintenance
1. The magnetic plate level gauge body is not allowed to have close to the magnetic material around, and the fixed wire is forbidden, otherwise it will affect the normal operation of the magnetic plate level gauge;
