Control box
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.
Main functions
Control mast lifting
Automatic pressure maintenance
Optional remote control
Control cabinet material and surface treatment
1.5MM cold rolled steel plate
Surface spray
Guy rope & Ground brazing
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.
Cable
The mounting cable on the mast determines whether to use a straight cable or a spiral depending on its use, such as the number of cores of the cable bundle, the cross-sectional area, the shielding and the extension height of the mast, the initial height, the minimum inner diameter of the top cylinder of the mast, and the customer's requirements.
spiral cable is divided into a built-in spiral cable or an external spiral cable.
Straight cable
Field of use
Performance comparison
Field of use
Generally used for cable diameters greater than 20mm, mast extension height greater than 15 meters, or the use of the same cable due to some interference.
Performance comparison
a.Advantages: simple structure, easy installation, and low price.
b.Disadvantages:1.Receiving environmental impact, rubber is easy to age.
2.need an external settling cable device, or manually settle the cable.
3.When the wind is strong, it will cause additional lateral force of the mast.
Spiral cable
Field of use
Performance comparison
Field of use
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.
Performance comparison
A.Inner spiral:
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
B.External spiral:
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
Self-locking
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。
