YJGQ-40 hydraulic rail clamp
The YJGQ-40 is a heavy-duty Hydraulic Rail Clamp designed to secure outdoor rail-mounted machinery against high winds and prevent tipping. It acts as a "storm brake," clamping onto the rail head to immobilize the equipment during non-working periods or severe weather.
The model number breakdown is as follows:
YJGQ: The series designation for Hydraulic Rail Clamps.
40: The Clamping Force Rating of 400 kN (approx. 40 tons of force).
Products Description
💡 Key Features & Characteristics
Hydraulic Actuation:
Power Source: Operated by a dedicated hydraulic station (typically the YZ(J)-14-9 model).
Operation: The clamp is hydraulically actuated. It uses hydraulic pressure to apply the clamping force onto the rail head. It is designed to lock the machine in place securely.
Release: When the crane needs to move, the hydraulic system releases the pressure, retracting the clamping arms to clear the rail.
High-Capacity Clamping:
Force: The YJGQ-40 generates a massive 400 kN of clamping force.
Anti-Skid Force: Based on the standard friction coefficient ( μ≈0.25μ≈0.25 ), the anti-skid resistance is calculated as 2×Clamping Force×μ2×Clamping Force×μ . For the YJGQ-40, this results in approximately 200 kN of resistance against lateral wind loads.
Rail Compatibility:
It is designed to fit heavy-duty rail profiles, specifically compatible with QU120 (and likely QU100) rails, which are standard for large port cranes.
Robust Construction:
Environment: Designed for outdoor use in harsh environments (ports, shipyards) with an operating temperature range of -5°C to +40°C (some specs cite 0°C to 40°C).
Durability: The structure is built to withstand shock loads from sudden gusts of wind. The hydraulic components are sealed to protect against dust, rain, and corrosion.
Safety & Control:
Power Supply: The system typically runs on AC 380V (3-phase) for the hydraulic motor and AC 220V for the control circuit.
Integration: It is often integrated with the crane's safety PLC to engage automatically when wind speeds exceed a certain threshold.
🏭 Typical Applications
The YJGQ-40 is essential for large-scale outdoor gantry cranes where wind stability is critical:
Port Machinery: Ship-to-shore cranes (STS), Rail-Mounted Gantry cranes (RMGs).
Shipyards: Large gantry cranes used for lifting ship sections.
Heavy Industry: Outdoor overhead cranes in steel mills or power plants.
Wind Power: Cranes used for erecting wind turbines.

| Model Variant | YJGQ-40 |
| Clamping Force | 400 kN (Kilonewtons) |
| Hydraulic Station | YZ(J)-14-9 (Rated Pressure ~14 MPa) |
| Rail Compatibility | QU120, QU100 |
| Power Supply | AC 380V / 50Hz (3-Phase) |
| Anti-Skid Force | Approx. 200 kN (depending on rail condition) |
| Operating Temp | -5°C to +40°C |

Note: The YJGQ-40 is significantly more powerful than the YJGQ-16 or YJGQ-25 models. It is specifically engineered for the heaviest cranes. Ensure the rail foundation and the crane's leg structure can withstand the reaction forces generated by the 400 kN clamping load. The hydraulic station (YZ(J)-14-9) is a critical component; ensure it is properly maintained to prevent pressure drops that could compromise safety.
