NBS-Tiltmast | Wind & Water Monitoring Mast

Our Australian manufactured NBS-Tiltmast is our ’tilt-over’ style mast suitable for locations where the ‘fall’ of mast to gain access must be controlled and easily/safely accessible such as middle/edges of roads where raised platform equipment is unable to gain access or where not required, reducing access/maintenance costs. Our NBS-Tiltmast is supplied in a disassembled form, to both reduce courier costs and storage requirements until installed. The NBS-Tiltmast is supplied with all fixing bolts/washers/nuts for assembly of the base and arm. Specific technical specifications and mounting guidelines for mounting the in-ground base are supplied with each unit. A wide range of accessories for mounting/attachments and cable management are available separately.
