A utility vehicle for power emergency repair includes a cab, a carriage and a lighting device, including mounting bases, a wire pole, a rotary base and a lamp assembly. A rotary shaft is bridged between the mounting bases, and the rotary base is fixedly connected to the rotary shaft. First and second positioning units are provided on the top of the carriage. The rotary base has first and second positioning surfaces, the first positioning unit includes a first limiting platform, and the second positioning unit includes a rotation limiting plate and positioning plates. The positioning plates is supported on a lower end surface of the rotation limiting plate. The utility vehicle further includes a driving assembly and first and second contacts. A trigger signal is generated and the driving assembly is controlled to release braking on the rotary shaft when the first and second contacts contact each other.

A solar and fuel powered portable light tower includes a portable base, a light panel arm, a primary power source, a secondary power source, and a control box. The light panel arm, that includes a plurality of light panels, is connected to the portable base while the primary and secondary power sources are positioned within the portable base. The control box, which is positioned within the portable base, controls the solar and fuel powered portable light tower. An insulated wall within the portable base separates the primary power source and the secondary power source for safety purposes. The plurality of light panels is preferably powered the primary power source that includes a plurality of photovoltaic panels and batteries. The plurality of light panels is also powered by the secondary power source that also acts as an onsite generator.

Expandable light towers suitable for mounting to a mobile unit, and methods for their use. Such an expandable light tower includes a telescoping assembly comprising first and second telescoping units. The second telescoping unit is telescopically received in the first telescoping unit to configure the expandable light tower to have retracted and extended configurations. The light tower further includes a light-mounting assembly mounted to the second telescoping unit and a mounting assembly coupled to the first telescoping unit and adapted to mount the telescoping assembly to a hitch of a mobile unit. The mounting assembly enables the telescoping assembly to pivot about a transverse axis.

One purpose is to smoothly raise and lower a telescopic post used in a floodlight. There is provided a floodlight that includes: a telescopic post that has a plurality of posts whose outer diameters are made gradually smaller, into which the posts can be loosely fitted, and that can be extended and contracted in an up-down direction; a lighting unit attached to the post located on the innermost side; a raising and lowering unit that extends and contracts, in the up-down direction, the posts in conjunction with each other; a base that the post located on the outermost side is fixed to; and dampers that connect a side surface of the post located on the outermost side and a side surface of the post located on the second outermost side.
