It shall have raising lowering system, comprising of head frame luminaries carriage suitable to install luminaries in symmetrical arrangement, double drum with, SS rope 6mm dia (min), LM-6 head frame pulley block, trailing cable connector, integral power tool motor, manual handle etc. and as per special terms and conditions attached (Annexure A). The mast shall have 10 light fittings each of 250W LED lamps of SMD LED chips having colour temprature 6000K +/- 500K ,60 degree beam angle and with poly carbonate optic lense. The luminarie shall be of IP66 , tested for High voltage 1.5 kV for one minute and shall be protected against surges and transients >/= 4.0 kV. The mast shall have suitable feeder pillar-box with all control contactors and gears for the automatic on off switching of lights. Suitable aviation lamps shall also be available with the mast. All the materials shall be corrosion resistant and suitable for highly corrosive industrial area where there is likelihood of sulphur dioxide and other corrosive gases. Scope also include construction of shallow foundation with suitable grade concrete for the highmast considering the safe soil bearing capacity at site at suitable depth with all materials and labour. The designs including foundation details must be vetted by the OEM and competent Structural Consultant form IIT/NIT, not below the rank of Asst. Professor
