High Quality SPM*7-90 Spindle Electric Mast  

SPM mast refer to spindle drive mechanical lock combined electric mast is developed by tianhemast. The high performance SPM mast family are available made by lightweight composite material or high tensile strength aluminum to fulfill the needs of telecommunication, SAT communication,  reconnaissance, surveillance. With low nested height and small space claim, the SPM mast is light weight mobile solution for application requiring rapid automatic deployment, maximum reliability and high directional pointing accuracy. Internal and external mountings are allowed for shelter installation as well. The advantages of SPM mast is that it avoid traditional stainless steel rope elevation method , it revolutionarily uses spindle drive plus mechanical locks for precision elevation without 1mm heights tolerance , rope would become longer when using for long time. And it avoid the rope from critical weather condition as well for more durability and stability.…
