Provided is a cam buckle including a body having at least one slot, and a cam arm movably coupled to and pivotable relative to the body. The cam arm has teeth for engaging a webbing and at least one boss for engaging the at least one slot. The cam arm is biased in an unlocked position where the teeth are configured to engage the webbing, and the cam arm is movable to a locked position where the teeth are configured to be disengaged from the webbing and the at least one boss is held in the at least one slot.

An apparatus to lower or raise landing gear on a trailer or semi-truck comprising a tool having a center body with a coupling device and a power coupling that is selectively engageable with a rotatable projection on the landing gear. The power coupling is operatively engaged with a worm gear within the center body and thereby with the coupling device. A powered drill is engaged with the power coupling and is actuated to rotate the power coupling in a first direction or in a second direction. The power coupling rotates the worm gear, which rotates the coupling device and thereby the projection on the landing gear. Rotation of the projection in one direction lowers the landing gear. Rotation of the projection in the opposite direction raises the landing gear. The user selects to raise or lower the landing gear simply by causing the drill chuck to rotate clockwise or counter-clockwise.

A tensioning device includes a housing, a drive member, an inner sleeve, a driven member, a cable member, and a clutch assembly. The housing includes an attachment feature. The drive member is rotatably coupled with the housing. The inner sleeve is disposed in the housing and is coupled with the drive member. The inner sleeve is rotatable together with the drive member relative to the housing. The driven member is disposed within the housing and is operably coupled with the drive member. The clutch assembly facilitates selective coupling between the drive member and the inner sleeve. The cable member is coupled with the driven member. The driven member is slidably coupled with the inner sleeve such that the driven member and the cable member are slidable together between a retracted position and an extended position in response to rotation of the inner sleeve.

Tie-down assemblies and methods of their use are provided. In one embodiment, a tie-down assembly may include a buckle, a first strap, and a second strap. The buckle may include a frame, a handle pivotably attached to the frame and configured to pivot about a first axis between an open position and a closed position, and a drum rotatably attached to the handle and configured to rotate about a second axis, wherein the second axis is spaced apart from and extends parallel to the first axis. The first strap may be attached to the frame, and the second strap may be configured to removably attach to the drum.

A universal chain tie down assembly includes an anchor base and an associated turret, with a cannon pivotally connected to the turret. The proximal portion of a tensioning rod is associated with the cannon. The tensioning rod further includes a distal portion associated with a hub, along with a tool attachment portion that is configured for engagement by a tool for rotation of the tensioning rod. First and second arms of a constant tensioning device extend from proximal ends associated with the hub to distal ends spaced distally of the hub. A chain is associated with a distal end of the constant tensioning device, such as by being linked to the curved portion of a U-bolt of the constant tensioning device. A tension lock assembly and/or an anti-vibration assembly may be employed to prevent a vibration-induced change in the tension in the universal chain tie down assembly.

An expandable net, including a plurality of spring reels. Each spring reel has a housing defining an interior and having a central anchor, in the interior, and further defining an opening; a spool rotatably mounted inside the housing, and having a side wall; a tension member wound about the spool and extending through the opening and having a distal end; and a spiral spring anchored at the anchor and having an outer end, attached to the side wall. Further, the distal end of each tension member is attached to the housing of another spring reel, thereby forming the expandable net.

An improved tensioning system and method of restraining cargo is provided. The tensioning system is easy and quick to operate. The tensioning system is compact and minimises space within a cargo bay. The tensioning system allows a greater angular displacement of a tensioning line over conventional tensioning system, such as a ratchet and strap mechanism.

A locking assembly is provided including a frame. The frame includes a slot and a recess positioned at a top portion of the frame. The assembly further includes a handle rotatably coupled to an end of the frame that is opposite the slot. The handle is rotatable between an open position and a closed position. The slot is configured to receive an attachment means. When the attachment means is in the slot and the handle is in the closed position, the handle is positioned in the slot on top of the attachment means such that the attachment means is prevented from moving with respect to the frame. A latch may be mounted to the handle. The latch is slidable between a locked position where a pin extending from the latch engages the recess of the frame and an unlocked position where the pin is positioned outside the recess.

A tensioning device includes a housing, a drive member, a driven member, and a cable member. The housing includes an attachment feature. The drive member is rotatably coupled with the housing. The driven member is disposed in the housing and is operably coupled with the drive member. The cable member is coupled with the driven member. The driven member is slidably coupled with the housing such that the driven member and the cable member are slidable together between a retracted position and an extended position in response to rotation of the drive member.
