Regular inspection is the foundation of safe trailer handling, beginning with a systematic check of landing gear assemblies before every move. Look for bent or cracked housings, loose bolts, and worn pinions that could compromise support when the trailer is raised or lowered. Verify that the feet sit firmly on clean, level ground, and check for signs of rust, hydraulic leaks, or excessive play in the leg sections. Maintain a dependable record of findings and corrective actions, so maintenance teams and operators share an accurate history. When issues are identified, tag out the unit and restrict operation until the problem is resolved, preventing unpredictable gear collapse during coupling or uncoupling.

A proactive lubrication routine extends the life of landing gear and reduces the risk of sudden failures. Clean all pivot points and seals, apply manufacturer-recommended grease, and ensure no dirt or debris blocks movement in the screw jack, torque tubes, or drop legs. Regularly inspect for hardened grease that attracts grit, which can accelerate wear. Use the correct lubricant grade and replenish to the specified levels, avoiding over- or under-lubrication that could hinder smooth operation. Train crew members to perform lubrication with the equipment stabilized and supported by wheel chocks. This attention to detail pays dividends through quieter operation, steadier retraction, and safer handling during both coupling and uncoupling.

Safe coupling hinges on a predictable, well-maintained support system that doesn’t shift unexpectedly as the vehicle interfaces with a tractor. Begin by ensuring the landing gear is fully retracted when not in use, so the trailer rests on its own axles. Then, as you lower the legs for connection, confirm that each foot has solid contact on firm ground and that no debris interferes with the pad’s surface. If you notice any wobble, stop and re-level the trailer before proceeding. Recheck alignment periodically during the process, especially on uneven surfaces. Clear communication and consistent procedures prevent misalignment, reducing the chances of gear shock or collapse.

Modern trailers rely on robust, well-maintained landing gear to stabilize the coupling process and protect workers. Implement a standard pre-connection checklist that includes testing responsiveness of the crank handle, verifying hydraulic integrity, and confirming the locking mechanism engages fully. Teach operators to avoid standing beneath raised legs and to keep hands away from pinch points during extension and retraction. Use wheel chocks and cribbing when needed to prevent unintended movement. Regularly compare actual performance against manufacturer specifications and adjust maintenance schedules to account for environmental conditions such as cold starts or heavy loads. A disciplined routine minimizes accidental gear failure and associated injuries.

When inspecting the landing gear, pay attention to the screw mechanism’s threads, paying particular attention to any stripping or corrosion that could impair smooth motion. Smooth operation depends on clean threads and properly centered components. If any resistance is felt, stop and diagnose the cause—binding due to debris, a bent leg, or a misaligned mounting bracket. A trained technician should straighten or replace compromised parts before reassembly. After adjustments, apply the correct lubricant and run the gear through multiple cycles to ensure consistent performance. Document the results, confirming that all parts meet safety standards before the trailer is moved again.

Support structure health is critical for preventing dangerous failures during load transfer. Inspect brackets, crossmembers, and fasteners for cracks, elongation, or looseness. Replace worn components and re-torque bolts according to specifications, never relying on guesswork. Consider upgrading to higher-grade fasteners if severe wear is anticipated in rough terrains or frequent heavy-duty cycles. Keep the area around the landing gear clear of tools and materials to avoid trip hazards during maintenance and operation. Emphasize teamwork: one person reports a concern, another confirms the fix, and a third tests the system under controlled load. Strong communication underpins safe protocol adherence.

A thorough inspection extends beyond the visible frame to hidden areas where safety-critical components reside. Examine the mounting brackets for elongation, check the hydraulic release valves for proper function, and verify that the crank handle operates without binding. Look for signs of corrosion near pivot points that could indicate underlying material fatigue. When doubt arises about the integrity of a component, replace it rather than risk a failure mid-operation. Maintain spare parts on site to minimize downtime and ensure that all repairs restore the original safety margins. Consistency in checks builds confidence and protects workers from unpredictable gear behavior.

Training and practice reinforce proper technique during coupling, support engagement, and decoupling. Teach operators to establish a stable, level work area, deploy chocks, and communicate clearly through each step. Emphasize slow, deliberate movements of the landing gear and avoidance of sudden jerks that could trigger foot or hand injuries. Use visual and audible cues to indicate when it is safe to proceed, and never bypass safety steps to save time. A culture of careful, methodical action sustains long-term safety and reduces the likelihood of collapses during critical moments.

Environmental conditions influence landing gear performance, so tailor maintenance to weather and terrain. In freezing conditions, lubricants may thicken and hinder operation; in heat, metal expands and clearances can change. Schedule checks accordingly, and use de-icing or anti-seize products where appropriate. Regularly test the system under simulated loads to confirm stability before attempting a full coupling sequence. Watch for ground subsidence or soft soil, which can destabilize the trailer once the legs are extended. Anticipating these factors helps prevent sudden gear collapse and reduces the risk of injuries to nearby workers.

Post-operation care closes the loop on safe handling, ensuring problems do not linger after a task ends. Park on level ground and lower the legs to full contact, then apply parking brakes and wheel chocks as a final safeguard. Conduct a quick walk-around to verify no tools are left behind and that the landing gear remains in safe condition. Record any irregularities or maintenance performed, so future crews benefit from shared knowledge. A routine cooling-off period after assembly also reduces fatigue-related errors and supports ongoing accountability for equipment integrity.

Finally, establish a maintenance log that tracks all landing gear components across the fleet, including serial numbers, service dates, replacement parts, and measured clearances. Use standardized forms and digital records where possible to enable quick retrieval during audits or inspections. Encourage feedback from operators who experience unusual gear behavior, as early warnings can prevent costly failures. Regular audits should verify that the documented procedures align with actual field practice. When the data reveals trends, adjust maintenance intervals and training content to close any safety gaps. A data-driven approach keeps everyone safer and more confident during coupling and uncoupling.

Enduring safety comes from integrating mechanical care with disciplined operation, so crews view landing gear maintenance as an essential part of daily work. Build routines that combine inspection, lubrication, testing, and clear communication into a single, repeatable process. Emphasize that even minor issues deserve attention and completion before work continues. Foster a culture of proactive reporting rather than blame, because timely fixes protect workers and equipment alike. By embedding these practices into standard operating procedures, fleets protect people and assets from preventable injuries caused by collapsed supports or misaligned couplings. Evergreen guidelines like these endure as the baseline for safe trailer handling.
