iWeiss Line-Shafts consist of modular drums with tubular or solid drive shafts connecting to a single gear motor with a primary brake. The cable drums can be supplied as helically grooved or pile-ons for the specified travel requirements, allowing for a multi-line vertical lift.
As with all IWEISS machinery, the Line-Shafts are designed with an 8:1 safety factor and redundant braking. Other standard safety features are a 4-cam rotary limit switch, E-stop system and hold-to-run operation controls. Each drum has a keeper to maintain cable placement. All Line-Shafts can be specified for a lifting capacity of 100 lbs to 10,000 lbs, multiple lift lines at fixed or variable speeds. Our Line-Shaft can be configured in numerous mounting orientations for a variety of uses pending the project needs and structure attachment requirements.
WHEN USED IN A FIRE CURTAIN SYSTEM, A HYDRAULIC DAMPENER IS ADDED TO THE MOTOR STATOR TO MEET STANDARD OPERATING REQUIREMENTS OF NFPA80 AND ANSI.
