Product 01: High Mast Systems
High Masts, Engineered for Extremes
BPP high masts range from 12.5 m to a monumental 70 m+, in configurations carrying 6, 9, 12, 18, 24, 32 or 112 light fittings. Every mast is engineered to IIT Kanpur’s Wind Velocity Certification standard and finished in our own hot-dip galvanizing plant in single-dip sections up to 14 m long.
Applications
- Street & highway lighting
- Oil depot & refinery lighting
- Stadium & apron lighting
- Port & dockyard lighting
- Telecom / cellular networks
- Wind turbine installations
Standard High Mast Range
Luminaire options: 6 / 9 / 12 / 18 / 24 / 32 / 112 fittings. Masts above 30 m, alternative luminaire counts and non-standard configurations are engineered to order; please share the site wind zone and luminaire schedule with your enquiry.
Engineering Advantages
- Minimum wall thickness never less than 4 mm: against the 3 mm typical of imported masts.
- Single longitudinally welded mast available on request.
- Balanced 3-point suspension lantern carriage for true, even lowering.
- Double-drum winch with compensating disc: carriage tilt is straightened without lowering the carriage ring.
- 3-pulley system with guide to prevent wire and cable slip-off in any position.
- Torque limiter and limit switch for automatic motor trip-off during docking of the lantern carriage.
- Telescopic slip joints with overlap of 1.5 × diameter at every site joint.
- Hot dip galvanized in a single dip in our in-house plant, up to 14 m long sections, 86 micron minimum.
- Anti-vandalism base door, 1200 × 250 mm, with wooden stack board and 150 × 150 mm cable termination box.
