YFX-600/80 Electro-hydraulic Storm Braking Wedges Brakes

YFX-600/80 electro-hydraulic storm braking wedges brakes

The YFX-600/80 is a specialized Electro-hydraulic Wind Wedge Brake (also known as a Storm Brake or Anti-Wind Device). Unlike standard brakes that stop motion, this device is designed specifically to secure large outdoor cranes against high winds and storms.

💡 Key Features & Characteristics

Storm & Typhoon Resistance:
The YFX-600/80 is a heavy-duty unit designed to withstand extreme weather. It is rated to resist 12th-grade typhoons (wind speeds > 32.4 m/s), making it essential for coastal port machinery.

Electro-hydraulic Actuation:

Power On (Release): When the crane is operating, the Ed-series electro-hydraulic thruster is energized. It pushes a lever mechanism to lift the wedge block away from the rail, allowing the crane to move freely.

Power Off (Engage): When power is cut (or during an emergency), the thruster retracts. A spring mechanism forces the wedge block down onto the rail, physically jamming the wheel to prevent movement.

Fail-Safe Safety Design:
The device is Normally Closed. In the event of a power failure or sudden storm, the wedge automatically drops onto the rail to lock the crane in place.

Wedge Locking Mechanism:
Instead of friction pads (like a drum brake), this device uses a wedge-shaped steel block. When engaged, the wedge shape creates a mechanical lock against the rail head, preventing the crane wheel from rolling.

High-Performance Materials:

Wedge Block: Made of high-wear-resistant steel to withstand the abrasion of the rail and the immense force of the wind.

Bearings: Pivot points feature self-lubricating bearings for maintenance-free operation and long life.

Smart Monitoring:
Equipped with limit switches (release limit switches) that provide feedback to the crane's control system. This ensures the wedge is fully retracted before the crane is allowed to move, preventing damage to the rail.

Manual Release:
Includes a manual release mechanism, allowing maintenance personnel to lift the wedge manually if power is unavailable.

🏭 Typical Applications

The YFX-600/80 is strictly used for large-scale outdoor rail-mounted machinery:

Port Machinery: Container gantry cranes (Ship-to-Shore), Rubber Tyred Gantry cranes (RTG), and Rail Mounted Gantry cranes (RMG).

Shipbuilding: Large gantry cranes used in shipyards.

Mining & Metallurgy: Outdoor bucket wheel excavators or stacker-reclaimers.

Railways: Large freight handling cranes at rail terminals.

📋 General Technical Specifications

Note: The YFX-600/80 is typically used as an auxiliary safety device. It works in conjunction with the crane's primary service brakes (like disc or drum brakes) and other storm anchors (like rail clamps or pins). It is specifically designed for "in-service" braking (stopping the crane if the wind picks up while working) and "out-of-service" securing.
