The system would have an arrangement for installing and maintaining lights at ground level. The tilting arrangement of the Tower would be perfectly balanced and would not give any jerk or need a push / pull to activate the operation.
The trolley base would be fabricated from channel frame work. The base would be provided with suitable number of riggers of suitable extendable length to provide complete stability of towers when fully erected. The riggers after extension would be grounded with the help of screw jacks having suitable free base of steel / cast iron. The trolley would be fitted with a tow-eye, tail light reflectors etc.
The total tower structure shall be given anti rust treatment by painting after sand blasting. Before painting two coats of primer shall be applied. During final painting of complete tower structure standard safety color codes hall be complied with so as to provide clear visibility to the operation of dumpers, dozers, tippers etc. for safety against collision / damage during night time
The MLCP shall be of outdoor type having IP 55 class of protection with incomer for power from mains/DG Set. 30mA RCBO of adequate rating shall be provided as main income and MCBs shall protect the outgoing cables from short circuit. The cables from MLCP to the individual luminaries shall be prewired and so laid and protected that it does not infringe with raising and lowering of the segments of tower. For motorized winches the interlocking arrangement should be provided to ensure that the tower tilting winch cannot be operated while the tower is in telescopic mode and vice versa. Suitable transformer can be incorporated into the system to meet the specific output requirements.
We can supply complete design calculation for the towers selected. Most of our towers are type tested by a Govt. Test Laboratory.
