Project Overview

Tower Inspection Winch Unit

Neumann Industrial Coatings completed all the required abrasive blasting and industrial spray painting for a self contained diesel hydraulic triple winch unit for an American company Tower Inspection, built by Neumann Equipment. The winches will be used for tower inspection is a certified materials lifting winch built in accordance with “Industry Best Practice” safety standards for use by the Commonwealth for maintenance and inspection of communications and transmission towers.

Neumann Equipment provided a fully self-contained diesel hydraulic system capable of a combined winch line pull of up to 10 Tonne simultaneously for use on towers up to 365m high. The system was integrated with significant safety measures such as overwind, overload, overspeed and continuous hydraulic monitoring to ensure that it met “Industry Best Practice” globally.

The system will be used for the next six months at the Harold E Holt communication station before being shipped to the USA for use by Tower Inspection. All design and manufacturing were completed in house by Neumann Contractors and completed in under 12 weeks from order.

Scope of Works

Abrasive Blasting

The steel components were abrasive sand blasted using GL 40 Steel Grit (about 0.5mm) to White Metal specification (Sa3, AS 1627.9).

Industrial Coatings

Primer – All components were primed with Nason Industrial 2K ZP epoxy primer. This is a two component epoxy anti-corrosive primer pigmented with zinc phosphate.

The fast drying and handling properties, together with extended overcoatability, make this an excellent primer for factory application prior to full system application on site. Nason Industrial 2K ZP provides good abrasion resistance which minimises mechanical damage in transit between the factory and site.

Top Coats – We then sprayed two tops coats of Nason Industrial NI-610 2K polyurethane in the desired colours, graphite on the base and golden yellow for the winches and power pack.

The Nason Industrial NI-610 2K polyurethane is two component, high gloss, polyurethane finish, and provides excellent durability and flexible application. It is suitable for use in both new construction and as a maintenance finish which can be used in a wide variety of environments including offshore structures, chemical and petrochemical plants, bridges, pulp and paper mills, and in the power industry.

Commercial transport & components;
Mobile mining, earth moving, construction & agricultural equipment and attachments;
Structural steel industrial and commercial;
Industrial plant equipment and machinery;
Pipeline & tank exteriors.

Product Description:

NI-610 is a “High Performing” 2 pack (2K) high gloss, isocyanate cured polyurethane topcoat based on Axalta owned technology. The resulting durable coating delivers excellent weathering and anti-corrosion properties (when applied over the recommended primers & Primer surfacers) and is suitable for use where a high performance type of 2K PU coating is required.

Product Features:

Excellent gloss & colour retention
Excellent flow and application properties
Hard and abrasion resistant
Excellent chemical resistance
Fast dust free drying time
Range of hardeners and thinners

Product Benefits:

Long lasting film integrity & durability
Superior quality and high gloss finish
Extended service life
Use for manufacturing & material handling
Fast turnaroundtime & high productivity
Flexibility in application & performance

Product Uses/Applications:

The product provide excellent topcoat appearance and protection of properly primed metal surfaces in industrial environments. It is suitable for painting commercial vehicles such as buses, refurbishment of commercial vehicles, machinery and any article that requires a better than standard style 2K PU performance. This topcoat can be applied over properly prepared Nason® Industrial primers and surfacer coated substrates.
