SPOT LINE HOIST 200 Kg
Lighting Suspension
FEATURES

SAFETY
Approved by the Internationally recognized testing authorities of TÜV to the
German standards, the DIN 15560 part 46 standards, and by the U.L. Laboratories
standards.
These Standards are directly associated with safety of suspensions systems
mounted above an assembly of people.
The safety features incorporated into the De Sisti
Spot Line Hoist include, a dynamic self sustaining worm-geared set motor, with a screw
helix angle less than 4 degrees to prevent back winding, two 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 and over load and slack line detection on each wire rope.

INCREASED EFFICIENCY / LOWER OPERATING COSTS
The Spot Line Hoist can be
used as an individual hoist or grouped together for lifting and moving Scenery in a Studio
application or for lowering a Lighting Truss in a Theatre application. The Scenery Hoist can
be moved along rails. This product can be either installed in permanent fixed positions
directly to the I-beam sub-structure of the building, or to any supporting grid to pick up
move scenery or other heavy objects in the Studio. The Spot Line Hoist has an added
feature as illustrated above, to be installed under a rail system with either a manual or a
motorized trolley. This allows for the ability to move the sets along rails and to be
positioned in the precise location where they are needed. The Hoist used as a Spot line
can lower a Lighting Instrument, Chandeliers in an auditorium or they can be grouped
together to lower a lighting Truss.

MECHANICAL
A special frame maintains a clear separation between the moving parts
(mechanical elements in motion), like steel ropes, winding discs, diverter pulleys, load
sensor mechanisms) and the electrical components (electrical wiring, motor switch-gears,
safety micro switches, travel limit device). The separation of these elements allows
maintenance procedures to be performed safely and the electrical components maintained in
a clean environment.

OPERATIONAL
400-lbs/181 kg.

The Spot Line Hoist is capable of lifting a (SWL) safe working load of
The maximum travel distance is 35 feet /10.5 meters.
OPTIONAL FEATURES The De Sisti Spot Line Hoists offer several unique optional
features:
1.
A provision to enable the hoist to be raised or lowered with a cranking tool in
case of a hoist failure.
2. Positioning Control memorizes and recalls the position of each hoist and record
that position into a preset.
3. DMX Up/Down and Positioning Control via any standard DMX controlled lighting
system.
SPECIFICATIONS
The De Sisti Spot Line Hoist shall be a completely self-contained enclosure housing a drive unit of
monoblock design.
The assemble shall house a 1.1kw 3-phase motor integrated with a dynamic
self sustaining worm-geared set with a screw helix angle less than 4 degrees to prevent back
winding. (Systems needing break motors to obtain a dynamic stop or systems with only static self
sustaining gear motors will not be accepted).
The motor shall be equipped with a built-in thermal protection device, designed to stop the
electrical supply to the motor in case of excessive heat. The device shall automatically reset when
the motor temperature decreases and allow the unit to return to normal operation.
Incorporated into
the hoist system shall be cut out safety micro switches (double activated SPRING –LEVER) for
each cable line for slack line and over load detection, plus travel limit switches, one for the top
limit plus extra safety stop switch and one bottom limit switch and plus extra safety stop switch
The hoist frame shall be a folded steel housing and designed in such a way as to separate all
moving parts from the electrical components and power elements. The unit shall house along with
the motor all the wiring. The housing shall also incorporate transparent inspection panels in order to
visually inspect all relevant safety parts, including load sensing, lift cable discs and lift cable
terminations.
The average lifting speed shall be 25 feet per minute. The SWL (self working load) shall be 400
lbs./ 181 kg with a maximum travel of 35 feet. Each of the four steel lifting cables shall be 4mm in
diameter, constructed in (7 groups X 19 wires), with a breaking force on each wire rope of at least
1,200 kg / 2,400 lbs.
The entire device shall be DIN approved under section #15560 Part 46, (Worldwide Safety Standard
for overhead devices) be TÜV certified and carry the U.L. label approved as a complete system.
Hoists with U.L. approved components but not tested and approved as a complete system will not
be accepted
There are several Control Options offered by De Sisti Rigging and Automation

Up /Down Push Button Control with (optional) remote control

DMX Up / Down Control as well as the Positioning Control

HRC System ( hoist remote control ) with manual back up.

ICARUS Control System (memory control for hoists and automated lighting).
