Functions and requirements of electric lifting lamp pole

Time：2020-10-22 View：

Xuedian NJXD vehicle-mounted 10 m electric lifting mast can realize functions and requirements
a) vehicle-mounted 10m electric lifting mast, with a height of 10m and a height of shut height not higher than 2.3m.
b) the vertical bearing weight of vehicle-mounted 10 m electric lifting mast should not be less than 60kg, and the weight should not be higher than 100kg (including motor).
c) the maximum pipe diameter of the electric lifting mast should be no more than 170mm, the material is magnalium, and the number of sections is 6.
d) the lifting mast integrates electric and manual, and the installation position of manual handle should conform to humanized design.
e) the vehicle-mounted 10 m electric lifting mast should have the functions of moisture-proof and wet, salt spray, mold, sand and dust, etc.
f) all Deployment Time: manual and electric are not more than 90 seconds.
g) mechanical mode: steel cable drive, which requires stable lifting, no impact and jitter.
h) under the load standard combination mainly based on wind load, the deflection angle and torsion angle of the electric lifting mast at the position of the antenna under the normal use limit state are no more than 2 °.
i) locking type: the electric lifting mast adopts automatic friction brake disc and Internode automatic locking system to avoid "disjunction" or "falling" during operation ", to ensure the use and stability under extreme environmental conditions.
j) when the electric lifting mast is in the working state, its self-lowering capacity shall not exceed 50mm after continuous operation for 200 hours.
k) under the condition of 30mm ice wrapped, the electric lifting mast should be able to lift safely.
l) permanent load (including structural weight, fixed equipment weight, initial stress of cable, etc.) and variable load (wind load, ice-wrapped load, earthquake action, snow load, temperature change, etc.). Among them, Lotus is considered as 20 m/s, ice-wrapped is considered as 30mm, and earthquake intensity is considered as level 7. Equipped with rotating cable tray system, the cable is made of non-metallic materials.
m) meet the installation requirements of various professional antenna lifting mast.
n) the electric lifting mast should have good wind resistance and stability. It should have the ability to resist level 8 wind (20 m/s) without using ground cable, and level 12 wind will not be damaged.
o) equipped with lifting height display system with 485 interfaces, which can realize remote monitoring.

 

 

Advantages and disadvantages of lifting lamp pole types and production process

 

1. Types of lifting lamp poles and their advantages and disadvantages
If the lifting light pole is divided according to the material, it can be divided into iron lifting light pole, FRP lifting light pole, cement lifting light pole and aluminum alloy lifting light pole, etc.
(1) advantages and disadvantages of iron lifting lamp pole
Advantages: high strength.
Disadvantages: corrosion or rust is easy to occur, transportation and installation costs are high, and installation methods and surface treatment methods have certain limitations.
(2) advantages and disadvantages of FRP lifting light pole
Advantages: light quality, convenient installation, and plug-in installation method can be adopted.
Disadvantages: short service life, no recycling, high maintenance cost, and easy to be damaged by equipment.
(3) advantages and disadvantages of cement lifting lamp pole
Advantages: plug-in installation method can be adopted, with good strength and no need to spray.
Disadvantages: heavy weight, difficult installation and high cost, can not be recycled, there is a certain risk.
(4) advantages and disadvantages of aluminum alloy lifting light pole
Advantages: it has good corrosion resistance and is basically maintenance-free. The quality is light, so it is convenient to install and transport. The surface treatment methods are various and can be recycled. In addition, it can also adopt plug-in installation methods.
Disadvantages: The strength is worse than that of iron lamp post.

 

2. Production process of lifting lamp pole
The production process of lifting lamp pole is as follows: blanking → bending → welding → repairing and grinding → shaping → fitting head → installing bottom plate → welding bottom plate → opening door → welding door strip, electrical strip, lock bottom → curved fork → galvanized → spray → general inspection.
