1.1 Application
The telescopic mast is a electric lifting device which can lift high antenna on the vehicle. It can automatically and safely lift the top load to the specified height in a short time.It’s widely used in mobile communications, mobile lighting, surveillance, radar systems and electronic warfare industries.
1.2 Features
a)The telescopic mast has a compact structure,can be freely installed on vehicle ,ground etc.It greatly provides a flexible and mobile platform to fix top load.
b)The mast adopts traditional linkage mechanism,each section works at same pace.The lifting time is short and there is no frequent locking and unlocking process.
c)The mast adopts square structure,and high strength aluminum alloy material,which provides excellent guding ability,anti-bent,anti torsion performation.
d)The mast uses efficient and reliable lead screw drive as power source,which ensures stablility and reliable locking function at any height.
e)The mast can extend and retract automatically.When automatic lifting function fails or the power is cut off,the lifting can be done manually.
f)The mast adopts dual power system,the rise and fall are driven by different powers,which ensures the mast can work in harsh enviroments.
g)The mast has strong environmental adaptability,can work in plain,hilly,mountain,plateau,coast line and other areas.Each section is sealed,waterproof,anti-ice and sand.The inside and outside surface of tubes are specially treated,which provides exellent anti-mold,salt spray and other properties.
1.3 Main structure and functionThe mast is composed of mast tubes,reduction gear,driving motor,transmission mechanism,wire rope linkage mechanism,control part and other accessories.
Functions:
a)Automatic and manual operation
b)Stop at any condition
c)Self locking at any height position

3 Installation and test
3.1 Preparation before installation
a) Open the cases,take the mast tubes and accessories out
b) Get the fixing tools ready,raise the mast by 50mm
c) Fix the cable collective frames on the mast,note the sizes
d) Cable boxes should be fixed by “botton-big size to top-small size” See Figure
