The Hamworthy Combustion TopDownTop AWL Retractable System has been developed to meet the stringent demands of the Oil & Gas industry as well as any other Industrial requirement. This produce provides a simple, reliable and cost effective means to maintain lamps mounted at high level on stacks, flare systems and structures where operation is needed in hazardous environmental conditions or where maintenance is difficult or near impossible.
For elevated flare systems, or similar structures, maintenance required on AWL lamps in many cases can only be achieved by a complete plant shutdown with the resultant loss of production. The TopDownTop™ AWL Retractable System provides the most reliable and effective maintenance solution without the need for plant shutdown.
The TopDownTop AWL Retractable System is supplied fully assembled. The following components are supplied for each lamp or double lamp arrangement:
- Complete Winch (optional powered)
- Internal wire rope and accessories
- Internal and external supported Trolley
- Electrical cable and connectors
- Top Rail complete with pulley and heat shield (if needed)
- Bottom Rail complete with winch flanges
- Systems suitable up to 210 metre elevation installation
The lamp unit is fixed to a trolley, which travels on a rail between grade and the top of the structure by means of a continuous wire rope. The lamp is permanently connected to the power and signal cables and does not require an electrical docking station. All parts are located at high level, requiring no regular maintenance.
A winch (manual or powered), to raise and lower the trolley, is located at ground level and can be fixed to the bottom of the rail or mounted on a separate concrete plinth. The winch operates in both directions and is fitted with a safety brake to protect equipment and personnel.
The whole system is designed to cater for any movement and expansion and can be adapted to any shape of the structure without requiring extra ground area in the customer's plant, as can happen with "rope and pulley" solutions. Hamworthy Combustion can also supply the complete engineering package, providing all necessary details for local installation.
