Heavy-Duty Square Mechanical Parking Jack 6,000kg (170mm Stroke)

The Heavy-Duty Square Mechanical Parking Jack 6,000kg is an extreme-capacity landing gear and leveling prop stand engineered to provide ultra-heavy-duty vertical lift, positive chassis leveling, and unyielding stationary support for industrial plant trailers, heavy agricultural machinery, multi-axle transport chassis, and heavy caravans. Built to withstand an extraordinary static load capacity of 6,000 kg (6 metric tons), this mechanical jack ensures positive, fail-safe support on unpaved, soft, or uneven terrain, eliminating the risks of hydraulic creep or settling under high tongue weights.

Fabricated with a rigid 70 mm square outer tube and a matching 60 mm square inner telescoping leg, this square-tube profile delivers exceptional torsional strength and lateral deflection resistance compared to conventional round-body jacks. Offering a dedicated 170 mm lifting stroke within a low-profile 460 mm overall closed length, it provides maximum under-chassis ground clearance during transit while delivering high structural rigidity under full operational loads.

Key Features & Benefits:

• Massive 6,000 kg Static Load Capacity: Engineered to safely carry up to 6 metric tons of downward tongue and chassis weight, making it suited for heavy plant transporters, earthmoving equipment trailers, and large agricultural machinery.

• Rigid Square Profile Construction: Features a 70 mm square outer body paired with a 60 mm square inner tube, maximizing resistance against bending forces, torsional twisting, and binding under extreme static weights.

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

• Controlled 170 mm Usable Stroke: Provides 170 mm of continuous vertical adjustment to facilitate precise coupling and uncoupling from towing vehicles.

• Compact 460 mm Retracted Length: Low-profile closed height maintains ample ground clearance, preventing underbody dragging or snagging on steep ramps, ruts, and job site obstacles during transit.

• 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, loose gravel, soft sand, or sun-softened asphalt.

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

• All-Weather Protective Finish: Industrial-grade corrosion-resistant coating protects the structural steel tubing and internal drive threads against road salt, moisture, mud, and harsh outdoor weathering.

Ideal Applications:

• Heavy Plant & Machinery Transporters: Excavator trailers, compaction roller carriers, and low-bed heavy equipment haulers requiring high tongue weight capacity during loading, unloading, and stationary parking.

• Agricultural Machinery & Implements: Rigid front-end stabilization for high-capacity grain bins, heavy fertilizer spreaders, field sprayers, and tractor-towed implements.

• Industrial & Mining Service Rigs: Heavy landing gear for mobile diesel generator skids, compressor units, water bowsers, and site service platforms.

• Heavy-Duty Commercial Caravans & Trailers: Leveling and front-end drawbar support for extra-heavy tourers and specialized transport chassis.
