ST-17 Air Spider Basket

The original Spider basket! With decades of use in the field, the Spider ST-17 air powered work basket is the industry standard for work in refineries, tank farms, shipyards, offshore platforms and heavy construction. The current Spider ST-17 basket has been redesigned to meet your needs and simplify your ownership experience—lowering your cost of ownership, improving the reliability of the components, and making it easier to service this product right.

A self-contained, single line unit, the ST-17 accommodates two workers to double productivity. Contractors can add modular platforms or plank sections between two ST-17s to form a double line suspended scaffold. With modular sections, workers can quickly connect sections without special tools to create a larger working span with flydecks attached. The unit comes equipped with numerous safety devices to ensure safe operation.

The ST-17 is the finest quality work basket in the world and is a result of years of improvements, primarily from customer feedback.
