Optional: auxiliary hoists – Rotating bed mounted,
can be tted with one or two auxiliary drums
grooved for 28 mm wire rope, and both having
36,760 lb linepull on all layers. ese two drums
can be used independently or in tandem to suit a
variety of lift applications.
Optional: freefall hoists – Rotating bed mounted,
can be tted with one or two free fall equipped
drums grooved for 28 mm wire rope. Freefall
