Heavy-Duty Square Mechanical Parking Jack 3,000kg (300mm Stroke)

The Heavy-Duty Square Mechanical Parking Jack 3,000kg is an industrial-grade landing gear and leveling prop stand engineered to provide high-tonnage vertical lift, rigid chassis leveling, and positive unhitched parking for heavy commercial trailers, agricultural implements, plant machinery haulers, and large caravans. Rated for an exceptional static load capacity of 3,000 kg (3 metric tons), this mechanical jack ensures dependable, drift-free front-end tongue support across uneven, soft, or sloping ground, facilitating effortless coupling and decoupling under heavy drawbar loads.

Constructed with a heavy-gauge 70 mm square outer body tube and an inner 60 mm square telescoping leg, this square-tube profile delivers superior torsional strength, bending resistance, and lateral stability compared to standard round jacks. Offering a generous 300 mm lifting stroke within a compact 620 mm overall closed body length, it combines high structural rigidity with extended vertical adjustment to bridge wide ground clearance gaps effortlessly.

Key Features & Benefits:

• Massive 3,000 kg Static Load Capacity: Safely supports downforce loads up to 3 metric tons, making it suited for heavy tandem-axle trailers, equipment carriers, livestock trailers, and large touring caravans.

• Heavy-Duty Square Profile Construction: Features a 70 mm square outer body paired with a 60 mm square inner leg, maximizing resistance against bending moments, torsional twisting, and binding under heavy static loads.

• Generous 300 mm Usable Stroke: Delivers a full 300 mm of continuous vertical travel to easily accommodate high-clearance off-road chassis, steep driveway inclines, and varying vehicle towball heights.

• Well-Balanced 620 mm Retracted Profile: Optimized closed height maintains high under-chassis ground clearance during transit while providing ample extension reach when deployed.

• Precision Mechanical Screw Drive: High-torque internal mechanical acme lead screw delivers low-effort vertical adjustment and positive mechanical load holding with zero slippage or hydraulic pressure drop over long-term parking.

• Integrated Wide-Base Steel Footplate: Standard welded pressed-steel base foot broadens ground contact pressure, 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 Protective Coating: Industrial corrosion-resistant finish shields the structural steel tubing and internal drive threads against road salt, moisture, mud, and outdoor weathering.

Ideal Applications:

• Commercial & Plant Equipment Trailers: Tandem-axle goods trailers, mini-excavator carriers, and machinery haulers requiring high tongue-weight support during unhitched loading.

• Heavy Agricultural Machinery: Stabilizing mobile sprayers, feed bins, water bowsers, and tractor-towed farm implements.

• Heavy Touring Caravans & Campers: Front drawbar leveling and steady support on campsite pitches, grass stands, and gravel sites.

• Horseboxes & Livestock Trailers: High-stability landing gear capable of handling heavy tongue weights and dynamic animal movement during hitching.
