De Sisti CH250 Point Hoist

FEATURES

• SAFETY The CHANDELIER HOIST (motorized lifting device) features an ELECTRICAL DISCONNECT which allows a lighting Fixture to be lowered to ground level for relamping or servicing without the need to manage the electrical feed cables as the device is lowered. This is accomplished by disconnecting the stationary upper contact member (the Power feed) from the lower contact / movable member (the luminaire) without the need to unlatch the device. While in the upper position and connected to the current, the stem and guide assembly and the upper contact assembly maintain positive contact 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 Winch Assembly, Safety Micro Switches for Overload and Slack Line Detection and the Limit Switches, Two for the top and Two for the bottom (1+1) safety. The shallow housing of the Stationary Member allows the hoist to be mounted in tight spaces within the ceiling. The CHANDELIER HOIST can be specified with a 5 pole electrical disconnect for up to (2) 20 amp Circuits with a Common Ground. The lower Stem and Guide Assembly, which is disconnected as the hoist is lowered to ground level for lamp replacement, also contains an outlet for testing the replacement lamps while it is at ground level.
• MECHANICAL The Mechanical Design incorporates TWO elements, a stationary upper contact assembly which houses TWO Independent Lifting Drums, one for each lifting line, a Motor Winch Assembly, Safety Micro Switches for Overload and Slack Line Detection and the Limit Switches, The movable Lower member contains the Mating Stem and Guide Assembly, which disconnects the single or double 20 amp circuits as the hoist is lowered and a 20amp outlet for testing the replacement lamps.
• OPERATIONAL The CHANDELIER HOIST is capable of lifting a (SWL) safe working load of 250lbs / 114 kg, the maximum travel distance is 65 feet / 19.8 meters.
