A solid mast raiser system is disclosed herein. The solid mast raiser system may include a slot configured to house a mast. Further, the slot may be further configured to be inserted in to a predrilled bore in the ground. Further, a length of the slot may be matched to a depth of the predrilled bore in the ground. Further, the solid mast raiser system may include a stanchion configured to be attached to the slot. Further, the stanchion may be concentrically aligned with the slot. Further, the stanchion may rest upon a cable. Further, the solid mast raiser system may include a launcher coupled to the stanchion through a cable. Further, the launcher may be configured to raise and retract the stanchion. Further, the launcher may be configured to be affixed to the ground. Further, the launcher may comprise a first hole concentrically aligned with the slot.

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.

A utility pole caddy has a trapezoidal-shaped component with a base and an opposing top. The top includes a concave portion effective to receive a utility pole positioned horizontally relative to the ground. The dimensions of the utility pole caddy are effective to deny pole movement without mechanical assistance. This utility pole secures utility poles at temporary work sites and prevents rolling, reduces vandalism by requiring a machine to remove a pole from the device, and assists crews setting poles by elevating the tops of the poles prior to setting.

The present invention is an improved apparatus and method for forming a retractable tower or column. The present invention includes pointed hooks wherein the hooks are attached to each section of a section chain, one in a horizontal direction and one in an off-set manner. The section chains are placed on a take up mechanism in an operable position and then raised utilizing a motor. As the section chains are raised, they are guided by a guide tower, rollers, shims, and gear racks into a position whereby hooks from adjacent sections of the section chains form coupled engagements. The coupled engagement of the hooks of the sections of each adjacent section chains thereby form the column.

A subsection of a tower section comprises a shell segment of the tower section and at least a longitudinal flange mounted to a longitudinal side of the shell segment for connecting to a longitudinal flange of a further subsection of the tower section. Here, the longitudinal flange comprises a part of a surface contour extending from a contact surface of the longitudinal flange which is provided for a connection to a longitudinal flange of a further subsection to a connecting surface connected to the shell segment. The part of the surface contour comprises a distance to a contacting plane passing through the contact surface.

A lattice type transmission tower leveling device for leveling a transmission tower with respect to a ground surface. The tower leveling device includes a series of side supports positioned at first and second sides of the transmission tower. The leveling device also includes a support beam that is secured to a third side of a transmission tower that is leaning and a second support beam that is secured to a fourth side of the transmission tower opposite the third side. The device further includes a series of brace members that are interconnected to form a lattice brace structure. The lattice brace structure is coupled to the upright members of the transmission tower. The tower leveling device also includes a lift beam secured to the side supports of the tower and a series of hydraulic cylinders that extend from the lift beam to the first support beam. Linear movement of the cylinders causes the transmission tower to rotate about the axis of rotation so that the tower can be leveled and new tower base supports can be installed.

A method and apparatus for constructing a tower, where the apparatus may include a structure including a foundation including a plurality of hydraulic cylinders; a truss tower located on the foundation and configured to support a tower built on the foundation; and a controller configured to control extension and retraction of the hydraulic cylinders.
