Heavy-Duty Square Mechanical Parking Jack 1,500kg (Two-Stage / 710mm Stroke)

The Heavy-Duty Square Mechanical Parking Jack 1,500kg is an extended-travel, multi-stage landing gear and leveling prop stand engineered to provide ultra-long vertical lift, rigid chassis leveling, and positive stationary support for heavy commercial trailers, high-clearance off-road chassis, plant machinery haulers, and agricultural equipment. Rated for a solid static load capacity of 1,500 kg (1.5 metric tons), this mechanical jack delivers dependable tongue-weight support across uneven, soft, or steep terrain, facilitating effortless coupling and decoupling without hydraulic creep or sag.

Constructed around a multi-tier telescoping square profile featuring a 70 mm square outer body tube and nested 60 mm and 50 mm square inner legs, this multi-stage design achieves an extraordinary 710 mm lifting stroke while maintaining a compact 595 mm overall closed body length. This square-tube geometry delivers superior torsional rigidity and lateral deflection resistance compared to conventional round-body jacks, making it the ideal solution for tall drawbars and lifted suspensions that demand maximum vertical stroke.

Key Features & Benefits:

• High 1,500 kg Static Load Capacity: Safely supports downward static nose and chassis weight up to 1.5 metric tons, making it suited for heavy tandem-axle trailers, plant carriers, livestock haulers, and large touring caravans.

• Massive 710 mm Lifting Stroke: Multi-stage telescoping design provides an extensive 710 mm of continuous vertical travel, easily bridging extreme ground clearance gaps on high-riding trailers, off-road rigs, and steep embankments.

• Compact 595 mm Closed Profile: Despite its long extension capability, the retracted length remains at just 595 mm, preserving under-chassis ground clearance and preventing snagging during transit.

• Rigid Square Telescoping Construction: Combines a 70 mm square outer casing with nested 60 mm and 50 mm square inner sections to maximize resistance against bending moments, torsional twisting, and binding under heavy tongue loads.

• 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 hydraulic pressure drop over long-term parking.

• Integrated Wide-Base Steel Footplate: Standard welded pressed-steel base foot distributes concentrated downward tonnage across a broad ground contact area, preventing the post 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:

• High-Clearance & Off-Road Transporters: Lifted 4x4 expedition trailers, bush campers, and high-chassis agricultural equipment requiring maximum vertical reach.

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

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

• Horseboxes & Livestock Trailers: Firm, stable landing gear capable of handling heavy tongue weights and dynamic animal shifting during vehicle hitching.
