Heavy-Duty Mechanical Parking Jack 1,300kg (Ø57mm Outer Tube / 370mm Stroke)

The Heavy-Duty Mechanical Parking Jack 1,300kg is a high-capacity landing gear and leveling prop stand engineered to provide rigid vertical lift, stable chassis leveling, and positive unhitched parking for commercial trailers, heavy caravans, plant equipment trailers, and agricultural machinery. Rated for an impressive 1,300 kg static load capacity, this mechanical jack easily manages heavy tongue weights, ensuring smooth coupling and uncoupling without placing excessive strain on towbars or drawbar assemblies.

Designed around a heavy-wall Ø 57 mm round outer tube and Ø 50 mm inner telescoping tube, the unit provides an extended 370 mm lifting stroke within a compact 560 mm overall closed body length. To accommodate specific mounting and fabrication requirements, this parking jack is available in two configurations: With Inner Bush (for new installations requiring a pivot mounting sleeve) or Without Inner Bush (for direct replacement onto existing chassis brackets).

Key Features & Benefits:

• High 1,300 kg Static Load Capacity: Safely supports downforce loads up to 1.3 metric tons, making it suitable for heavy tandem-axle trailers, equipment carriers, livestock trailers, and large touring caravans.

• Extended 370 mm Usable Stroke: Provides a generous 370 mm of vertical travel to easily bridge substantial ground-to-chassis gaps across lifted suspensions, high-clearance off-road trailers, and uneven slopes.

• Compact 560 mm Retracted Profile: Measures just 560 mm when fully closed, providing high ground clearance and preventing underbody snagging on steep driveways, ruts, or speed humps during transit.

• Rigid Heavy-Gauge Round Tubular Design: Constructed with a Ø 57 mm outer barrel and Ø 50 mm inner telescoping tube, delivering superior bending and lateral deflection resistance under continuous load.

• Precision Mechanical Screw Drive: High-torque internal mechanical lead screw delivers low-effort, positive lifting and lowering with zero risk of hydraulic creep or settling over long-term parking.

• Integrated Wide-Base Steel Footplate: Standard welded steel base foot broadens ground contact pressure, preventing the jack leg from sinking into mud, soft sand, gravel, or hot asphalt.

• All-Weather Corrosion Protection: Durable zinc-plated protective finish guards internal drive components and external steel tubes against moisture, road grit, coastal air, and harsh weather.

Configuration Options:

1. With Inner Bush Option

• Mounting Setup: Supplied complete with the dedicated inner weld-on/pivot mounting bush.

• Best Suited For: New trailer builds, drawbar conversions, or custom chassis fabrications. The included inner bush acts as the primary pivot sleeve to be welded directly onto the trailer drawbar or A-frame, enabling 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.

Comparison Guide:

Ideal Applications:

• Commercial & Plant Trailers: Heavy utility trailers, tandem-axle car haulers, and machinery trailers requiring high nose-weight support during unhitched loading.

• Off-Road Campers & Caravans: Dependable leveling and front-end tongue support when pitching camp on soft sand, mud, or rocky terrain.

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

• Agricultural & Field Implements: Stabilizing mobile sprayers, feed bins, water bowsers, and farm machinery in loose soil and farmyards.
