YFX-710/80 Series Electro-hydraulic Storm Braking Wedges Brakes

YFX‑710/80 is a normally‑closed, electro‑hydraulically released wedge‑type brake, specially designed as a storm brake / windproof brake for port cranes, gantry cranes, quayside cranes, and other outdoor heavy machinery. It uses a wedge mechanism to provide strong, self‑energizing braking force.

Basic Identification

Model: YFX‑710/80

Type: Electro‑hydraulic wedge brake (storm / windproof brake)

Brake drum diameter: 710 mm

Matching electro‑hydraulic thruster: Ed‑80

Function: Storm braking, anti‑wind, anti‑sliding safety braking

Working Principle

Normally‑closed safety design:Braking force is provided by heavy‑duty compression springs.

Wedge boosting mechanism:The wedge structure amplifies spring force, delivering high braking torque with compact dimensions.

Release:The Ed‑80 electro‑hydraulic thruster is energized to lift the wedge and release the brake.

Automatic action:Immediately engages when power is cut or in emergency, preventing equipment from sliding in strong winds.

Key Features

High torque via wedge structure: Strong self‑boosting effect for reliable windproof braking.

Storm / windproof dedicated: Mainly used to secure cranes and outdoor machinery under typhoon or strong wind conditions.

Fail‑safe: Automatically brakes during power failure.

Stable performance: Suitable for harsh outdoor environments.

Adjustable braking force and shoe clearance.

Asbestos‑free friction linings with high weather resistance.

Typical Applications

Port gantry cranes (STS, RMG)

Shipyard gantry cranes

Outdoor bridge cranes

Any large mobile machinery requiring windproof / storm braking

Short version (for nameplate / catalogue)

YFX‑710/80 series electro‑hydraulic wedge‑type storm brakes are normally‑closed, electro‑hydraulically released windproof brakes with wedge boosting mechanism, used for anti‑sliding and storm safety braking of large cranes and outdoor heavy machinery.
