Premium Dealer Description

This Harrington ES050S is a top-tier industrial 5-ton lifting solution, engineered for the most demanding production environments. Manufactured in 2003, this unit hails from the peak era of Harrington’s rugged mechanical design, offering a massive 3.0 kW motor and a robust 20-foot lift.

The hallmark of the ES050S is Harrington's proprietary "The Guardian" Smart Brake Technology. This DC-current electromagnetic brake is fail-safe; it does not release unless the motor is energized, ensuring that even in a total power loss, the 10,000 lb load remains held securely. Designed with an H4 duty rating, this hoist is built for continuous operation in steel service centers, heavy fabrication, or foundry work where downtime is not an option. The unit features a totally enclosed, fan-cooled (TEFC) motor and an oil-bath gear train, providing smooth, quiet performance with minimal thermal buildup during high-frequency cycles.

Key Features & Advantages

• Smart Brake Technology: Features an electrical fail-safe design with a DC current system that activates instantly, drastically reducing wear on brake discs compared to standard AC brakes.
• Extreme-Duty Motor: The 60-minute, H4-rated motor features cooling fins and an engineered fan cover for superior heat dissipation.
• Nickel-Plated Load Chain: Equipped with Harrington's world-class, corrosion-resistant Grade 80 chain, certified for high fatigue resistance and wear.
• Precision Load Sheave: 5-pocket deep-groove load sheave reduces chain vibration and promotes true vertical lift, significantly extending the life of the chain and sprocket.
