The Langzhuo control box is the main control device of the pneumatic mast. The main functions include controlling the rise, fall and automatic pressure holding of the mast. At the same time, it also has the air pressure safety guarantee function. The chassis protection grade is IP43. Remote control can also be selected according to the customer's needs, making the control more convenient. A reasonable functional layout of the control layout provides a more convenient operating experience.
Control mast lifting
Automatic pressure maintenance
Optional remote control
1.5MM cold rolled steel plate
When the mast is raised, slight fluctuations will occur due to the wind force. In order to increase the wind resistance level and stability, it is recommended to use the guy rope and the ground brazing to make the mast more stable.
A.Inner spiral: generally used for cable straight less than 15mm, mast extension height less than 12 meters, use the same cable, etc.
B.External spiral: generally used for cable straight less than 25mm, mast extension height less than 15 meters, using the same cable, etc.
a.Advantages: no external environmental impact, cable is not easy to age. No need to manually recover cable.
b.Disadvantages:1.The outer sheath of the cable requires better air tightness.
2.The cable and cylinder have good sealing requirements and the structure is relatively complicated.
3.The price is more expensive
a.Advantages:no need to manually close the line
b.Disadvantages:1.The cable receives environmental impact and is easy to age.
2.The price is more expensive
The self-locking function enables the mast to automatically lock each section when it is raised, so that the mast can be used stably for a long time even without air pressure.
Due to the different inital height and payload, the self-locking is mainly divided into the bolt and the cable stayed type。
