4 5 Ton Commercial Four Post Lift with Overload Protection

Comprehensive Product Description

In a bustling commercial garage, technician safety must be prioritized above all else. Accidental overloading of lifting equipment is a serious hazard that can lead to catastrophic mechanical failure, damaged customer vehicles, and severe workplace injuries. The Eounice 4.5 Ton Commercial Four Post Lift with Overload Protection (Model ON-7445) is specifically engineered to mitigate these risks entirely. By integrating a sophisticated, automated hydraulic safety architecture with a colossal 4500kg (9500 lbs) lifting capacity, Eounice has created an industrial-grade hoist that actively protects your mechanics and your bottom line while delivering world-class performance.

The heart of this lift's safety system is its integrated hydraulic failure and overload safety valve protection device. If an operator inadvertently attempts to hoist a heavy commercial truck or loaded van that exceeds the strict 4.5-ton rating, the overload valve automatically bypasses the hydraulic pressure. This prevents the motor from burning out, protects the steel cables from over-tensioning, and ensures the vehicle never leaves the ground under unsafe conditions. Furthermore, in the highly unlikely event of a sudden loss of hydraulic fluid pressure, the heavy-duty mechanical locking structure engages instantly, halting the lift and securing the load. To prove its resilience, Eounice subjected this model to a punishing 120% dynamic load test and an extreme 150% static load test.

While its safety features act as an impenetrable shield, its operational capabilities make it a highly profitable asset for wheel alignment and auto body repair. Modern 3D camera and laser alignment systems require the vehicle to rest on a mathematically flawless, dead-flat surface. The Eounice ON-7445 provides this through a highly convenient and accurate platform leveling system. Mechanics can easily calibrate the expansive 4780mm (188 3/16″) long runways to eliminate any pitch or sway. The massive 3000mm (118 1/8″) width between columns guarantees that alignment towers have a clear, unobstructed line of sight to the wheel targets.

Core Product Advantages:

Active Overload Protection: The advanced hydraulic safety valve automatically prevents the lift from hoisting loads beyond 9500 lbs, eliminating the risk of mechanical failure.

Commercial 4.5 Ton Capacity: Provides the immense brute strength needed to safely elevate heavy luxury SUVs, commercial fleet vans, and extended cab pickup trucks.

Flawless Platform Leveling: Guarantees a rock-solid, dead-flat runway surface, which is the absolute most critical requirement for perfect 3D and laser alignment data.

Freely Movable Vice Runway: Adapt the track width of the lift on the fly, granting mechanics custom-tailored access for intensive undercarriage collision and auto body repair.

Integrated Rolling Jack Rails: The inner runways feature heavy-duty sliding rails for the rapid deployment of optional bridge rolling jacks, enabling wheel-free brake and tire service.

Extreme Load Certifications: You can trust Eounice engineering; this heavy-duty lift has successfully passed punishing 120% dynamic and 150% static load tests.

The versatility of the Eounice ON-7445 extends its value far beyond a standard alignment rack. The freely movable vice runway allows the technician to slide one side of the platform laterally, customizing the gap between the runways. This provides unparalleled access to the underbelly for dropping heavy transmissions or routing custom exhaust systems. With a rapid lifting time of ≤60s (upgradable with an optional aluminum motor) and an 1800mm (70 7/8″) maximum height, this 1358kg (2,994 LBS) Eounice lift ensures maximum shop productivity while keeping your technicians completely safe.
