A sliding tool assembly for a vehicle includes a sliding member configured to be slidably connected to a first accessory track of a vehicle. A base member is rotatably connected to the sliding member and rotatable about a first rotation axis. A first beam member is rotatably connected to the base member and rotatable about a second rotation axis. A second beam member is rotatably connected to the first beam member and rotatable about a third rotation axis.

A portable gantry crane formed of composite members includes a composite material I-beam. Two or more support members are formed of a composite material and each support member supports the I-beam when the portable gantry crane is in an upright position. Two or more end housings are included, each end housing enclosing a top end of one of the two or more support members and coupled thereto using adhesive. A plurality of latch structures are coupled with the I-beam, each latch structure including a latch, and each end housing having a latch receiver, each latch in combination with a latch receiver allowing one of the latch structures to be releasably fixedly coupled with an end housing. In implementations a plurality of latch structures are coupled with the I-beam, each latch structure having a latch structure enclosure and each latch structure enclosure at least partially enclosing one of the end housings.

A mobile tower system including a tower skid assembly sized to be accommodated on a truck. The tower skid assembly including a skid including one or more ballast compartments, a tower framework fixed to a deck, a tower pivotably coupled to the tower framework, and a hydraulic actuator connected to a top member of the tower to extend the top member a vertical distance relative to a base member of the tower.

A sliding tool assembly for a vehicle includes a sliding member configured to be slidably connected to a first accessory track of a vehicle. A base member is rotatably connected to the sliding member and rotatable about a first rotation axis. A first beam member is rotatably connected to the base member and rotatable about a second rotation axis. A second beam member is rotatably connected to the first beam member and rotatable about a third rotation axis.

In implementations a plurality of latch structures are coupled with the I-beam, each latch structure having a latch structure enclosure and each latch structure enclosure at least partially enclosing one of the end housings.

A portable crane formed of composite members. A composite mast is coupled to a composite boom. A boom end housing removably couples at a top of the mast and includes an enclosure. A first end of the boom couples within the boom end housing. A boom pivot couples to the boom end housing and couples the boom to the mast. An angle adjuster releasably secures the boom at a desired angle relative to the mast. In implementations an end cap is included at a second end of the boom, coupled to a sheave with a pin, the end cap covering a terminal end of a second end of the boom and extending along both sides of a slot in an upper surface of the second end and along a portion of a first side of the second end and along a portion of a second side of the second end.

A hoist assembly for a vehicle cargo bed may include a base portion operably coupled to a subframe of the vehicle in the vehicle cargo bed, a first pivot arm operably coupled to the base portion proximate a first end of the first pivot arm to pivot relative to the base portion between a deployed state and a storage state, a second pivot arm operably coupled to a second end the first pivot arm to pivot relative to the second end of the first pivot arm when transitioning between the deployed state and the storage state, and a carriage assembly operably coupling the first pivot arm to the base portion and enabling the first pivot arm to move relative to the base portion along a longitudinal axis of the base portion while the first pivot arm is in the deployed state.

A trailer for lifting and positioning at least one reel thereon. The trailer includes a pair of articulated arms comprising a first elongate member and a second elongate member pivotally mounted to the first elongate member. The first elongate members are generally horizontal and movable relative to the trailer between a retracted position and a rearwardly extended position. The second elongate members are pivotable between a horizontal position in parallel alignment with the first elongate members and an upright position wherein the second elongate members are orthogonal to the first elongate members. The second elongate members are provided with respective jacks to stabilise them with respect to the ground surface. A hoist to lift the reel from the support surface to an effective height greater than an effective height of a deck of the trailer is disposed between the second elongate members.
