Specialised Self Elevating Masts (EM and Winch Pulley Type)
Technical Specifications
DH Limited Masts meet both mobile as well as ground applications. Our Products include Self-Supporting, remotely controlled designs, as also mechanically launched variants. Mast heights of 05 meters to 32 meters have been produced and installed in several applications including providing lightning protection at the time of Missile launch (Over 300 systems of various types are already deployed by Users).
These Masts can be manual/ powered both by Single Phase or 3-Phase Systems and can be deployed speedily on ground.
Highly useful for Broadcast Vehicles, Radar Systems, Communication Systems deployed in the field, on temporary, Semi-permanent or as well as permanent modes.
These are rugged in design and have been tested under extremely stringent conditions.
Custom made Masts as per user requirements of Electro-Mechanical Mast and Winch Pulley Type are in service and Hydraulic & Pneumatic type can also be offered.
