The OZDH300-20LH Dyno-Hoist® is a high-capacity, long-lift manual lever hoist engineered for users who demand real-time load verification, added lifting height, and consistent lifting control. Designed with a 3 Ton (6,600 lb) load capacity and an extended 20 ft lift height, this model is built for applications where added vertical reach is essential—such as facility rigging, elevated structural work, mezzanine staging, machinery positioning, and industrial maintenance environments.

What sets this hoist apart is the integrated dynamometer load display that actively shows the load being lifted in kilograms or pounds. This allows operators to verify load weight instantly—without guesswork—and ensures safer lifting decisions. The system also triggers overload alerts when loads approach 126% of rated capacity, giving clear feedback that helps prevent unsafe misuse, protects lifting equipment, and supports OSHA-conscious work practices.

Durability is a core strength of the Dyno-Hoist® line. The OZDH300-20LH is built from all-steel construction, with fully enclosed gearing that shields internal components from dust, debris, contaminants and impact abuse—helping increase service life in harsh environments. A steel handle with a rubberized grip reduces hand fatigue and improves leverage for easier, more controlled manual operation. Its zinc-plated load chain provides corrosion resistance and is designed specifically for long-term reliable lifting under repeated tension cycles.

Heavy-duty top and bottom hook latches provide secure load engagement and ensure solid retention during lifting, lowering, and load transfer positioning. Also valuable for non-trade or mixed-experience environments, the unit is designed with long battery life to power the dynamometer display for extended periods without requiring frequent battery replacement.
