A ladder support device removably securable to the hitch receiver of a vehicle. The ladder support device comprises a frame having adjustable ground engaging legs. The frame includes a pivoting arm to be removably secured to the hitch of a vehicle to allow the frame to be positioned in a desired orientation relative to the vehicle. The frame includes a pair of brackets for receiving the feet of an extension ladder therein. Further, the frame comprises a pair of telescopic support arms that extend upward from the frame and that can be secured to a portion of the extension ladder so as to secure the ladder in an upright, angled orientation without having to rest the ladder against a support surface, such as the side of a building.

A levelling stabilizer for a ladder and the like comprising a transverse brace (1) adapted for bridging the bottom stiles (2) of said ladder, two leg portions (3) pivotally fitted to said brace and an adjustment arm (7) acting between said brace and said leg portions to allow each said leg portion to be independently moved between a first fully retracted position aligned longitudinally with its respective stile and a second fully extended position at an angle normal to said stile.

An adjustable ladder platform is an apparatus that aids in keeping extension ladders on firm, level footing having an open base frame that sits directly on the unlevel ground, roof surface, pavement or the like a flat surface, similar to a small tabletop that supports the feet of the extension ladder. The two components are then hinged together at one side of the frame. Then the opposite side is supported by two adjustable arms that are attached by bolts and wingnuts that can be attached and removed without tools. The arms are provided with multiple holes to accommodate varying grades. One side of the device is provided with an attached bubble level to ensure levelness of the upper platform to ensure safety. Finally, one side of the device is provided with a handle to facilitate transport.

A ladder leveling device and a ladder are provided. The ladder leveling device includes a base, a lifting support, and a support plate, where the lifting support includes a support frame, a sliding frame, a rod seat, and a sliding rod. The support frame is arranged on the base; the sliding frame supports the support plate and is slidably mounted on the support frame; the rod seat is fixed in the support frame and has a fulcrum therein; and the sliding rod has one end supporting the support plate and the other end slidably inserted into the rod seat, at least one adjustment plate is provided on the sliding rod, the adjustment plate has one end supported by the fulcrum and the other end being a free end for adjustment, and the free end maintains downward under the action of a limit spring.
