• Precise Anti-Drop: Ratchet-pawl single-tooth engagement braking structure prevents free-fall
• Overload Protection: Automatically locks when load exceeds 5000kg
• Double-Insurance Hook: Safety latch + closed latch design prevents disengagement

• Freewheel Mechanism: Quick cable release (4m in 32 seconds)
• Ergonomic Handle: 350mm extended design reduces effort by 30%

• Multi-Steel-Plate Pawl: 5000+ operation lifespan at rated load
• Hot-Dip Galvanization: No rust after 72-hour salt spray test
• Forged Steel Hook: Withstands 1000kg lateral impact

Ideal for heavy auto repair shops needing to pull 3500kg vehicles with precise control. Features oil-resistant grip and quick cable release for efficient rescue operations.

Perfect for construction sites requiring safe lifting of 2000kg steel beams at heights up to 15m. Rust-proof design ensures longevity in outdoor environments.

Enables precise positioning (≤3mm deviation) of 3000kg CNC lathes in confined workshop spaces without overhead cranes.

A1: Overload use is strictly prohibited. While protection activates at 5000kg, consistent overload reduces component lifespan and increases safety risks.

A2: No - the freewheel includes a buffer mechanism. Cable release speed is manually controlled (12.5cm/sec max) with built-in damping.

A3: Wipe dry after use, apply lithium grease monthly. For rust repair, use fine sandpaper and zinc-based repair agent.

A4: Check for debris and clean if found. Lubricate with lithium grease. If noise persists, contact service.
