Telecommunication and Power Transmission Structure Installation
A telecom or transmission tower normally carry various sixes of antenna or cable that are fixed to its structure or arms at various heights. In the case of telecom tower, they contain a significant amount of cables and cable trays, that run in a maze between different equipment such as meter panel, equipment cabin, isolating panels, distribution board, earthling system, underground sub main etc.
For power transmission towers they mainly consists of high/low voltage cables that connect between different towers and pulled into position by teams of steeple jacks or abseilers who are trained to pull wires and install the different sections of the tower structures. For green field projects, the structures will normally arrive on site in pieces and it is the job of Seacad to carefully assemble the structure piece by piece using rigging and slinging system with winches and anchor points to slowly build up the tower.
For the above 2 types of towers, Seacad is able to provide the following process:
- Repair and maintenance of the towers without the use of cumbersome crawler cranes or vehicle mounted cranes that take up space on congested sites or busy access road.
- Removal of obsolete equipment such as antennas/cables/panels/control boxes and reinstallation with minimal disruption to existing infrastructure and personnel including the public.
- Corrosion prevention works such as grit blasting or power tooling with touch up painting.
- For greenfield projects, Seacad can assemble and construct the towers using its own unique rigging and slinging system that is economically viable, safe and precise.
