There is disclosed a service trailer which may be quickly deployed to a site to provide potable water, electricity, lighting and a storage of grey water.

Disclosed is a compact portable light tower that can be stacked or nested. The light tower employs a scissors lift mechanism to raise a set of bar lights from a housing having a height of about 28 and a length of about 60, to an extended height of about 360. The scissors lift is extended and retracted by use of a linear actuator. Batteries or an engine/generator assembly is employed for operation of the actuator and light bar. The housing can be stacked for ease of storage and transportation. Outriggers provide stabilization of ground engagement.

The invention relates to a portable, skid mounted, wheeled and/or collapsible hybrid-power lighting and energy management system for harsh, remote and/or high latitude locations. The system combines an internal combustion engine (ICE) power source with a direct current power generator and a battery storage system for providing power to light system. The system may also include an ICE heating system and/or renewable solar and/or wind power systems in a manner that improves efficiency and reliability of operation in such locations, while preserving and improving functionality of operation and significantly reducing operator interaction during set-up and operation.

A stackable enclosure for support of a mast stored in horizontal position and rotatable to a vertically deployed position. The enclosure employs a housing have sidewalls constructed and arranged to support a plurality of stacked enclosures. The dimensions of the enclosure with wheels can allow for the transporting of thirty units on a single 48 drop deck trailer. The enclosure has a hinged lid to allow ease of access to the interior which can house a power system to operate a bank of lights. Outriggers positioned along each corner of the enclosure provide stability to the mast in high winds. A hinged axle can be used to pivot enclosure wheels upward, allowing the enclosure to rest flush on a trailer deck or ground surface.

A photovoltaic system includes a trailer, a solar panel, a battery, a lamppost, a turret, a shackle, a horizontal position-adjusting unit and an orientation-retaining unit. The trailer includes a cage supported on a chassis. The solar panel is supported on the cage. The battery is supported on the chassis and electrically connected to the solar panel. The lamppost includes a lamp supported thereon and electrically connected to the battery. The turret rotationally connects the lamppost to the chassis. The shackle is provided around the lamppost. The horizontal position-adjusting unit movably connects the shackle to the cage. The orientation-retaining unit retains the lamppost in a desired orientation relative to the shackle.

This invention concerns a light tower (10) having a main body (12) and a mast (26) extending from the main body (12) such that the mast (26) is extendable between a retracted configuration and at least one extended configuration. A lighting unit (34) is mounted to the mast (26). Supports (44), such as legs, are arranged to support the main body in use. Sensors (56) are provided for monitoring the load distribution of the light tower (10) between the supports (44). A controller (64) is configured to alter the load distribution of the light tower (10) according to a comparison between the monitored load distribution and a predetermined acceptable load distribution range.

A portable tower trailer having a light tower housing constructed to allow for both stacking and nesting which is beneficial in both storage and shipping of light towers is disclosed. The portable tower trailer employs a frame having a hinged axle that allows the wheels to operate in a conventional manner. The hinged axle further allows the wheels to be rotated upward allowing the frame to rest flush on the ground or stacked upon a similar shaped portable tower. The stackable light tower is constructed having a base employing an engine system and a fuel tank; and a mast pivotally coupled to the base and movable between a storage configuration and a positioning configuration. The storage configuration is when the mast is folded over an upper surface of the base whereby an additional light tower base or tower trailer may be placed or stacked over the top of the first light tower base.
