PURPOSE: A light tower equipped with a safety lifting means is provided to improve stability since a break bar supports a lower portion of a carriage while being projected from a pillar when a lamp platform is lifted. CONSTITUTION: A fixed terminal housing is installed to be projected to the top of a rail housing(2). A power connection means is magnetized by power provided from a control means. A power supply unit(35) outputs the power to a fixed terminal(33) according to the control of the control means. An inclined plate(36) is installed on the top of a carriage(10) in order to correspond to the inclined surface. A movable terminal(37) is installed on an upper side of the inclined plate in order to let a brush(38) correspond to the fixed terminal. |
