A spotlight hangs from the ceiling from the pantograph. Minimum length from the ceiling of 43 cm and maximum from the ceiling of 200 cm. It has an elastic system that counteracts gravity, so that lowering or raising a bulb is done smoothly. In the upper part it has a rail fixing system based on bearings. At the bottom of the 5/8 "spigot for fixing to the bulb. A steel cable is supplied with the pantograph as a safety fixation between the spotlight and the pantograph (double fixation system). Once the moving elements have been introduced into the rail, these stops close the possible derailment at the ends of all the rails. A cable carrier is also supplied so that the cables are arranged neatly across the ceiling and run freely on the rails when moving a spotlight. Avoid hanging cables. Each pantograph supports 10 kg of weight. .
