🛠️ Product Overview: YJGQ-60 Hydraulic Rail Clamp
The YJGQ series is an improved version of the standard YJG series, featuring a more robust structure and a "floating" mechanism to ensure even pressure distribution on the rail.
Model Number: YJGQ-60
Type: Hydraulic / Rail Clamp (Wheel Edge Brake)
Action: Normally Closed (Fail-Safe)
Braking: Spring-applied (Engages when hydraulic pressure is released).
Release: Hydraulic pressure releases the clamp.
Key Feature: "Floating" Structure. This design allows the clamp arm to self-adjust its angle, ensuring full contact with the rail head even if there is slight misalignment or rail wear.
📋 Key Technical Specifications

✨ Key Features
Fail-Safe Design (Safety): It operates on a "Normally Closed" principle. If there is a power failure or hydraulic leak, the spring force automatically engages the brake, ensuring the crane cannot roll away.
Floating Mechanism: Unlike rigid clamps, the "floating" design prevents point loading and ensures the friction block contacts the rail evenly, maximizing grip and minimizing wear.
High Reliability: Designed for harsh outdoor environments (ports, yards) with protection against dust, moisture, and salt spray.
Signal Feedback: Equipped with limit switches to provide electrical signals indicating the "Braked" or "Released" status, allowing for interlocking with the crane's control system.
Manual Release: Includes a manual release mechanism for maintenance or emergency operation.
🏭 Typical Applications
The YJGQ-60 is used in heavy industries where wind resistance is critical:
Port & Harbor Machinery: Large ship-to-shore cranes and mobile harbor cranes.
Outdoor Rail Cranes: Rail-mounted gantry cranes (RMG) and bucket wheel stacker-reclaimers.
Metallurgy: Outdoor cranes in steel mills.
