Heavy-duty door and parking lock engineered for vehicle impact and harsh outdoor conditions. Key benefits Built to last: High-temperature, corrosion-resistant, fatigue-resistant alloy steel and a reinforced steel plate provide long service life and resist deformation from repeated use or accidental impacts. Reliable in wet conditions: A molded rubber seal meets IP67 waterproofing standards, so the lock remains operational after hours of immersion and resists rain and splashes. Damage protection and alarm response: The lock’s elastic 180-degree rebound design lets it spring back after a vehicle impact and trigger an alarm, protecting the mechanism and helping prevent forced entry or further damage. All-season performance: Rated to operate between -10 C and 55 C, the lock performs in both cold winters and hot summers without loss of function. High load capacity: The thicker, heat-resistant steel alloy plate delivers a load capacity of 2 to 3 tons, so it withstands being driven over or pressed by heavy vehicles. Features and what they mean for you Material: High-temperature alloy steel that is corrosion and fatigue resistant — reduces maintenance and extends service life in demanding environments. Seal and protection: Rubber sealing achieves IP67 waterproofing — suitable for outdoor installations exposed to water and dust. Impact damping: Elastic 180-degree rebound mechanism cushions collisions, returns the lock to a safe position, and activates an alarm if struck — minimizes mechanical damage and notifies you of incidents. Temperature range: Operates from -10 C to 55 C — reliable performance through seasonal temperature extremes. Load rating: 2–3 ton maximum load capacity — resists accidental run-overs and heavy loads without permanent deformation. Typical applications (practical examples) Residential garage or driveway: Protect a private garage door or driveway post from accidental vehicle impact; the rebound-and-alarm feature alerts you if a vehicle strikes the lock. Commercial parking lots and reserved spaces: Secure parking stoppers or post-mounted locks against unauthorized use and vehicle collisions in outdoor lots. Industrial gates and access points: Use at loading-area doors or perimeter gates where forklifts, trucks, or heavy equipment might contact the lock; material strength and load capacity reduce downtime from damage. Installation and upkeep (practical notes) Designed for robust outdoor use; regular visual inspections and occasional seal checks are recommended to maintain IP67 performance. No special handling required for seasonal temperature changes within the rated -10 C to 55 C range. The durable alloy construction reduces the need for frequent replacement or repair after impacts.
