Heavy-Duty Mechanical Lifting Legs (Corner Steadies / Stabilizer Props)

Engineered for precision leveling, reliable chassis stabilization, and effortless parking support, the Mechanical Lifting Legs deliver factory-grade stability for commercial trailers, high-loaders, low-loaders, caravans, and heavy utility rigs. Built to handle demanding outdoor and transport environments, these stabilizer legs eliminate chassis sway, body roll, and tipping hazards during unhitched loading, unloading, and stationary storage.

Each unit is fabricated around a robust 45 mm square steel outer profile, delivering superior torsional rigidity and lateral deflection resistance compared to conventional round prop legs. With a dependable 500 kg maximum stationary load capacity, these legs are engineered for dual-mounting versatility—allowing direct under-chassis bottom installation on high-loaders or secure side/top mounting on low-loader chassis rails using standard M10 fasteners.

Available in two distinct stroke configurations (Small / 410 mm and Large / 510 mm), they provide custom-fit clearance solutions for standard-height utility platforms and high-clearance overland setups alike.

Key Features & Benefits:

• High-Strength 45 mm Square Outer Profile: Manufactured from heavy-gauge structural steel in a 45 mm square tube design, providing high load-bearing capacity and resisting twisting forces under static weight.

• 500 kg Maximum Stationary Load: Rated to safely support up to 500 kg of static downward load per leg, ensuring steady, sag-free footing for loaded cargo beds, living quarters, or machinery.

• Dual-Configuration Mounting Flexibility: Designed for bottom mounting directly beneath high-loader chassis platforms, or side/top mounting on low-loaders via an 80 mm hole-center pattern using twin M10 high-tensile bolts.

• Smooth Internal Mechanical Screw Drive: High-torque internal drive screw delivers effortless extension and retraction under load, providing micro-adjustable leveling without binding or slipping.

• Universal Winding Engagement: Compatible with standard caravan and trailer corner steady crank handles for rapid, ergonomic deployment on uneven or sloping surfaces.

• All-Weather Corrosion Protection: Protected by a durable zinc-plated surface treatment to defend against road spray, mud, moisture, and outdoor weathering.

Size & Configuration Options:

1. Small Size (410 mm Retracted / 180 mm Stroke)

• Retracted Length: 410 mm

• Extended Length: 590 mm

• Usable Stroke: 180 mm

• Recommended Ground Clearance: 450 mm – 500 mm (for bottom high-loader fitment)

• Best Suited For: Low-profile road trailers, compact utility haulers, and standard-height caravan chassis where ground clearance is limited and a compact travel footprint is essential to prevent snagging.

2. Large Size (510 mm Retracted / 230 mm Stroke)

• Retracted Length: 510 mm

• Extended Length: 740 mm

• Usable Stroke: 230 mm

• Recommended Ground Clearance: 550 mm – 650 mm (for bottom high-loader fitment)

• Best Suited For: High-clearance off-road trailers, bush campers, high-loader flatbeds, and heavy commercial transporters requiring extended reach over uneven terrain, ditch banks, or deep rutted ground.

Mounting Applications:

• High-Loader (Bottom Installation): Mounts directly underneath the trailer floor/chassis structure. Requires adequate vertical clearance (450–500 mm for the Small size, 550–650 mm for the Large size) between the chassis mounting plane and the ground.

• Low-Loader (Side / Top Installation): Fastens to the outer chassis rail or side body using two M10 bolts spaced at an 80 mm center-to-center hole pattern, allowing top or lateral fixing without encroaching on low ground clearance.
