Our range of light telescopic masts is available in extended heights between 2m and 20m which have been specifically designed to carry antennas,meteorology and telemetry equipments to be used on ground,on containers and vehicles.All masts are made of light aluminum alloy,fully anodized and corrosion-proof even in presence of sea fog.Our masts can be exteneded by compressor and can be easily transported to various typers of grounds.The design and construction of our masts ensure an excellent seal: the gaskets are made of special compound and can withstand temperatures between -30°C and +60°C.With high level tight-seal performance,the mast could descend less than 10mm under static state during 24hours.Air compressors need piston swinging to pump,which with heavy structure adopts high-strength PTFE material including graphite,pressure reaching 10KG with displacement 0.03m3/s.It’s characterized by low noise,statonary vibration.What’s more,our company has realized to fix control wire and electric wire in the internal light mast which is the first success in china.,the performance of equipment in appearance and application advancing more.Garden strongly recommend guy ropes and pickets to be used to secure extended masts higher than 7m from strong winds.Garden supplies various lengths of guy ropes with rapid tensioners.
