pressure while being held in position via the self sustaining worm-geared
set motor. The CHANDELIER HOIST is capable of lifting loads up to
250lbs (114 kg) SWL (safe working load) and has a TRAVEL DISTANCE
of up to 65’ (19.8 meters). The CHANDELIER HOIST incorporates all
safety standards set forth by the Internationally recognized testing
authorities of TÜV to the German standards, the DIN 15560 part 46
standards, and by UL laboratories standards. These standards are
directly associated with the safety of suspensions systems mounted
above an assembly of people. The safety features incorporated into the
CHANDELIER HOIST include, a dynamic self sustaining worm-geared
set motor with a screw helix angle less than 4 degrees to prevent back
winding in a dynamic or static position. TWO independent Stainless
Steel Band (10x0.3 mm. section each with rounded edges) lifting lines,
with the breaking force of each Lifting Line being 990 lbs (450 kg). There
are two sets of Safety Micro Switches, one for the top limit (plus an extra
emergency safety switch) and one for the bottom limit (plus an extra
emergency safety switch.) The Chandelier Hoist has both overload and
slack line detection on each Stainless Steel Band.
≫ FLEXIBILITY The CHANDELIER HOIST’S upper stationary member
measures only 9” H X 10” W X 25” L and houses TWO Independent
Lifting Band Drums capable of lowering the Luminaire up to 65’, a Motor Switches, The movable Lower member contains the Mating Stem and
Winch Assembly, Safety Micro Switches for Overload and Slack Line Guide Assembly, which disconnects the single or double 20 amp
