Crosby BL-C ROLLOX 3.6 Ton Closed Swivel Bail Golden Gate Hook

Crosby BL-C Golden Gate® Bullard Hook – One-Hand Operation. Self-Closing Security. Built to Last.

On hoists, cranes, and material handling systems where hooks are engaged and released repeatedly throughout the workday, the mechanism that opens and closes the gate matters as much as the hook's rated capacity. The Crosby BL-C Series Closed Bail Swivel Golden Gate® Bullard Hook delivers a self-closing, automatically locking gate that secures under load without manual intervention — and releases with a single hand when needed. That combination of effortless operation and positive load retention is what makes the Golden Gate® the trusted standard for high-cycle lifting environments.

Closed Swivel Bail — Flexible Connection, Stable Lift

The closed swivel bail accepts a hoisting line or shackle directly — no intermediate hardware required — and allows the hook to be freely positioned before the lift begins. Once loaded, the hook operates as a fixed unit, delivering stable, predictable load transfer throughout the lift cycle. QUIC-CHECK® deformation and angle indicators are built into every hook, enabling fast visual inspection of overload deformation and load angle compliance without removing the hook from service.

Constructed from brass alloy for long service life and corrosion resistance in demanding lifting environments, the BL-C series is built to a 4:1 design factor for dependable performance across extended service periods on hoists, cranes, and industrial material handling systems.

Four Gate Types. One Hook Family.

Crosby engineers the BL-C series with gate mechanisms matched to hook size and application frequency — ensuring the right locking system for every use case:

• LIF-LOK® (Size 1) — Spring-loaded gate that engages automatically on closure for light-duty, reliable locking on smaller hooks.
• PIN-LOK® (Sizes 2–4) — Horizontal stainless-steel pin engages a notch in the shank for secure retention; lever release provides controlled, deliberate unlocking.
• ROLLOX® (Sizes 5–9) — Dual-arm gate with trigger release designed for high-frequency use; fast-acting engagement and release without sacrificing security.
• TIP-LOK® (Sizes 10–17) — Two-arm locking gate secured by a spring-loaded pin in a milled shank slot; engineered for larger capacity hooks where positive locking under heavy loads is critical.

Key Applications:

• Industrial hoists and overhead crane systems
• Material handling and production line lifting
• Construction and infrastructure crane rigging
• Any high-cycle lifting application requiring reliable one-hand gate operation
