iWeiss', US manufactured, line-shaft consists of modular drums with tubular or solid drive shafts connecting to a single gearmotor 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 swith, E-stop system and hold to run operation controls. Each drum has a compression pinch roller 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 fiixed or variable speeds.  Soft start/stop is standard on all iWeiss equipment, as is supplied service requirements of 120v 20 amps on systems up to 1.5 Hp, three phase required beyond. 

Our line-shaft can be configured in numerous mounting orientations for a variety of uses pending the project needs and structure attachment requirements.
