Heavy-Duty Square Mechanical Parking Jack 600kg (255mm Stroke)

The Heavy-Duty Square Mechanical Parking Jack 600kg is a dependable trailer landing gear and leveling prop stand engineered to provide rigid vertical lift, stable chassis leveling, and positive unhitched parking for medium-duty commercial trailers, touring caravans, horseboxes, and agricultural equipment. Rated for a 600 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 a generous 255 mm lifting stroke within a compact 590 mm overall closed body length, it combines ample vertical travel with high under-chassis ground clearance during transit.

Key Features & Benefits:

• 600 kg Static Load Capacity: Confidently supports downward static nose and chassis loads up to 600 kg, making it ideal for single- and tandem-axle utility trailers, horse floats, campers, and mid-sized caravans.

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

• Generous 255 mm Usable Stroke: Delivers 255 mm of continuous vertical adjustment to easily bridge height differences, accommodate varying vehicle towball heights, and level chassis on uneven terrain.

• Compact 590 mm Retracted Profile: Minimal closed length ensures sufficient 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 ground contact area, preventing the jack leg from sinking into mud, soft sand, gravel, or hot asphalt.

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

• 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:

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

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

• Horseboxes & Livestock Trailers: Firm landing gear capable of handling nose weight and movement during hitching and unhitching.

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