Heavy-Duty Square Mechanical Parking Jack 800kg (350mm Stroke)

The Heavy-Duty Square Mechanical Parking Jack 800kg is a dependable trailer landing gear and leveling prop stand engineered to provide high-clearance vertical lifting, rigid chassis leveling, and positive unhitched parking for medium-to-heavy commercial trailers, touring caravans, horseboxes, and agricultural equipment. Rated for an 800 kg static load capacity, this mechanical jack provides steady, positive tongue-weight support on uneven, soft, or sloping ground, facilitating effortless coupling and decoupling without hydraulic creep or sag.

Constructed with a robust 60 mm square outer body tube and an inner 50 mm square telescoping leg, this square-tube profile delivers superior torsional strength and lateral deflection resistance compared to conventional round-body jacks. Offering an extended 350 mm lifting stroke within a compact 565 mm overall closed body length, it combines exceptional vertical adjustment travel with high under-chassis ground clearance during transit.

Key Features & Benefits:

• 800 kg Static Load Capacity: Confidently carries up to 800 kg of downward nose and chassis weight, making it well-suited for single- and tandem-axle utility trailers, horse floats, heavy campers, and mid-sized touring caravans.

• Rigid Square Profile Construction: Features a 60 mm square outer body paired with a 50 mm square inner leg, maximizing resistance against bending moments, torsional twisting, and binding under heavy tongue loads.

• Extended 350 mm Usable Stroke: Delivers a generous 350 mm of continuous vertical travel to easily bridge wide ground-to-chassis gaps, accommodate lifted off-road suspensions, and level drawbars on uneven terrain.

• Compact 565 mm Retracted Profile: Minimal closed length ensures ample road clearance during transit, preventing underbody snagging on steep driveway aprons, speed humps, and off-road ruts.

• Precision Mechanical Screw Drive: High-torque internal mechanical acme lead screw delivers smooth, low-effort vertical adjustment and positive load retention with zero slippage or drift over extended parking periods.

• Integrated Wide-Base Steel Footplate: Standard welded pressed-steel base foot distributes concentrated downward loads over a broad surface area, preventing the jack leg from sinking into mud, soft sand, gravel, or hot asphalt.

• Direct Chassis Integration: High-strength structural carbon steel body is optimized for direct chassis welding or mounting via heavy-duty structural bracketry on drawbars and A-frames.

• All-Weather Corrosion Protection: Durable industrial protective finish shields the external steel tubes and internal drive threads against road salt, moisture, mud, and outdoor weathering.

Ideal Applications:

• Commercial & Utility Trailers: Reliable front-end landing gear for goods trailers, luggage haulers, and tradesman trailers requiring stable unhitched support during loading.

• Caravans & Camper Trailers: Front drawbar leveling and steady support on campsite pitches, grass stands, and gravel sites.

• Horseboxes & Livestock Trailers: Firm, stable landing gear capable of handling nose weight and dynamic animal movement during vehicle coupling and uncoupling.

• Agricultural & Industrial Platforms: Front-end stabilizing and parking for mobile compressors, generator skids, water bowsers, and field implements.
