Heavy-Duty Square Mechanical Parking Jack 4,000kg (200mm Stroke)

The Heavy-Duty Square Mechanical Parking Jack 4,000kg is an industrial-grade landing gear and leveling prop stand engineered to provide extreme-load vertical lifting, rigid chassis leveling, and dependable stationary support for heavy plant trailers, commercial transport chassis, agricultural implements, and industrial platforms. Built to handle an impressive static load capacity of 4,000 kg (4 metric tons), this mechanical jack ensures positive, unyielding support on unpaved, sloping, or soft ground while facilitating controlled hitching and unhitching under substantial tongue weights.

Fabricated with a rigid 70 mm square outer tube and a matching 60 mm square inner telescoping leg, this square profile offers superior torsional resistance and lateral deflection strength compared to conventional round jacks. With a 200 mm lifting stroke housed within a compact 485 mm overall closed length, it delivers exceptional structural strength, low-profile ground clearance during transit, and zero hydraulic drift over long-term parking.

Key Features & Benefits:

• Massive 4,000 kg Static Load Capacity: Engineered to safely carry up to 4 metric tons of downward tongue and chassis weight, making it well-suited for heavy plant equipment trailers, multi-axle agricultural machines, and commercial haulers.

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

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

• Smooth 200 mm Usable Stroke: Provides 200 mm of continuous vertical adjustment to facilitate easy coupling and decoupling from towing vehicles across varied ground conditions.

• Compact 485 mm Retracted Length: Compact closed height allows for high ground clearance and prevents underbody snagging on steep ramps, rough terrain, or job site ruts during transit.

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

• Heavy-Duty Chassis Integration: Solid carbon steel body is optimized for direct chassis welding or mounting via heavy-duty structural bracketry on A-frames and drawbars.

• All-Weather Protective Coating: High-durability corrosion-resistant finish shields the steel structure and internal mechanical drive threads against road salt, moisture, mud, and outdoor weathering.

Ideal Applications:

• Heavy Plant & Equipment Trailers: Excavator trailers, roller transporters, and skid-steer haulers requiring high tongue weight capacity during loading, unloading, and parking.

• Agricultural Machinery & Implements: Stabilizing heavy field sprayers, seed drills, mobile grain carts, and tractor-towed spreaders.

• Commercial & Industrial Transport: Mobile diesel generators, compressor units, water bowsers, and heavy site machinery platforms.

• Low-Bed & Heavy Utility Trailers: Unhitched storage stability and front drawbar leveling on rough industrial terrain.
