Tasman Canvas was approached by a commercial pilot with a unique challenge, to design and prototype a helicopter load sling bag capable of transporting heavy equipment safely and efficiently. Working in some of the world’s toughest conditions, the client needed a solution that could handle weight, weather, and wear without compromise.
The pilot operated within the oil and gas industry in Papua New Guinea, where sling bags were used to move seismic exploration equipment into remote jungle sites. These loads were critical for ground crews setting up kilometres of sensor arrays in rugged, inaccessible terrain. The existing methods were unreliable and prone to damage, making transport both inefficient and costly.
Recognising an opportunity to improve performance and safety, the client partnered with Tasman Canvas to create a custom-engineered solution. Together, we developed a durable, reinforced prototype built to meet aviation-grade demands, combining precision stitching, heavy-duty materials, and practical design features suited to field operations.
Tasman Canvas collaborated with the client to design a heavy-duty PVC load sling bag reinforced with webbing and an innovative closure system using stainless steel rings on the main load strap. Custom tube webbing, sourced from a NZ manufacturer, was added to protect the straps. The prototype was load-tested and rated to 900kg.
After successful flight testing, the client ordered an initial batch of 10 bags, followed by 50 more after proven field performance. The feedback from end users was outstanding, with the design praised for its strength, reliability, and ease of use in demanding conditions.
