• SAFETY The safety features incorporated into the De Sisti Spot Line Hoist include, a static self sustaining worm-geared set motor, with a double braked motor to prevent dynamic overrun, 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). The separation of these elements allows maintenance procedures to be performed safely and the electrical components maintained in a clean environment. A SPECIAL PIVOTING YOKE, is allowing to tilt the SCENERY HOIST in different angles as its self body weight is neutral as free rotating on a central axis. The bottom buckle is determining the full machine vertical position when no load is applied.
This allows to pick up loads that are not perfectly aligned under the machine.
• OPERATIONAL The Spot Line Hoist is capable of lifting a (SWL) safe working load of 300 kg. The maximum tra
...vel distance can be 20 meters
• OPTIONAL FEATURES The De Sisti Spot Line Hoists offer several 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
Positioning and Speed control to permit synchronized action of several Spot line HoistsVIAC
