A self-contained, single line unit, the ST-180 features a working swath of 8 ft (2.4 m). Adding flydecks enlarges the ST-180 to 14 ft (4.3 m), accommodating two workers to double productivity. Contractors can add modular platforms or plank sections between two ST-180s to form a double line suspended scaffold. With modular sections, workers can quickly connect sections without special tools to create a maximum reachable working swath of 56 or 62 ft (17.1 or 18.9 m) with flydecks attached. The unit comes equipped with numerous safety devices to ensure safe operation.

Key Features

  • Electromagnetic-actuated primary brake engages whenever power is off.
  • Automated emergency brake engages in the event of sudden or excessive downward acceleration.
  • Overload limit switch halts upward travel when hoist is overloaded.
