Heavy-Duty Mechanical Parking Jack 900kg (Ø51mm Outer Tube / 250mm Stroke)

The Heavy-Duty Mechanical Parking Jack 900kg 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-to-heavy utility trailers, commercial haulers, caravans, and agricultural machinery. Rated for a 900 kg static load capacity, this mechanical jack delivers steady, positive support on uneven, soft, or sloping ground, facilitating controlled hitching and unhitching without hydraulic creep.

Constructed around a heavy-wall Ø 51 mm round outer body tube and a matching Ø 45 mm inner telescoping leg, the unit delivers an effective 250 mm lifting stroke within a compact 430 mm overall closed body length. To suit specific mounting and fabrication setups, this parking jack is available in two distinct ordering configurations: With Inner Bush (ready for pivot/swivel mount fabrication) or Without Inner Bush (ideal for direct chassis fitment or replacement installations).

Key Features & Benefits:

• 900 kg Static Load Capacity: Safely carries up to 900 kg of downward nose and chassis weight, making it well-suited for tandem-axle utility trailers, horseboxes, equipment haulers, and mid-to-large caravans.

• Precision Mechanical Screw Drive: High-torque internal mechanical acme lead screw ensures low-effort, controlled vertical lifting and positive load retention with zero slippage or hydraulic pressure loss over prolonged stationary parking.

• Generous 250 mm Usable Stroke: Delivers 250 mm of continuous vertical travel to accommodate varying towball heights, uneven ground levels, and sloping driveways during coupling and uncoupling.

• Ultra-Compact 430 mm Retracted Length: Minimal closed height maintains high ground clearance, preventing underbody dragging or snagging on steep ramps, curbs, and off-road ruts during transit.

• Rigid Round Tubular Steel Construction: Thick-walled Ø 51 mm outer barrel and Ø 45 mm inner tube provide high bending and lateral deflection resistance under continuous load.

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

• Corrosion-Resistant Protective Finish: Durable bright zinc-plated finish shields the structural steel body and internal drive threads against road salt, moisture, mud, and outdoor weathering.

Configuration Options:

1. With Inner Bush Option

• Mounting Setup: Includes the dedicated inner weld-on/pivot mounting bush.

• Best Suited For: New builds, custom chassis fabrications, or trailer drawbars being converted to a swivel/pivot-mount setup. The inner bush provides the primary pivot sleeve to be welded directly onto the drawbar or A-frame, allowing full swing-away functionality.

2. Without Inner Bush Option

• Mounting Setup: Supplied as the standalone parking jack assembly without the pivot bush.

• Best Suited For: Direct replacement of an existing, worn, or damaged jack where the original drawbar pivot bush or fixed mounting hardware is already welded in place.
