Product Details
1. Core working principle and structure:
Working principle: Equipped with a squirrel cage three-phase asynchronous motor, the motor operates in hydraulic oil. After being powered on, the motor drives the impeller to rotate, generating hydraulic pressure that pushes the piston and push rod upwards, thereby providing thrust; After power failure, the push rod returns to its initial position under the action of spring reset or external load.
Structural design: Adopting a compact oil filled design, the motor housing and junction box are sealed together, with a high level of protection.
2. Main technical parameters:
1) Thrust range: covering 120 N to 6300 N, different models can be selected according to requirements.
2) Travel specifications: Common trips include 50mm, 60mm, 100mm, and 120mm.
3) Power supply voltage: The standard configuration is 400 V AC, and some models support DC 220V or other customized voltages.
4) Protection level: up to IP65/IP66, can effectively resist dust and humid environments.
5) Working temperature:
Standard range: -25 ℃ to+40 ℃
Extended range (requiring special hydraulic medium): -40 ℃ to+70 ℃
6) Work system: Supports 100% continuous work system, with fast response speed and low maintenance.

| EB6300-120 II | 6300 | 120 | Ultra high load industrial braking system |
4. Application fields:
The EB series thrusters are widely used in industrial scenarios that require high braking stability and safety:
Lifting and handling: Port cranes, winches, material handling systems.
Heavy machinery: metallurgical rolling equipment, mining machinery, shipbuilding equipment.
Automation control: large valve drive, conveying equipment, and various industrial braking devices.
5. How to work:
1) Motor: An electric motor drives a centrifugal pump.
2) Hydraulics: The pump forces internal hydraulic oil underneath a piston.
3) Action: The oil pressure pushes the piston rod upward, releasing the mechanical brake.
4) Release: When powered off, the pump stops, the oil returns to the reservoir, and the piston retracts.
6. Comparison of EB and Ed electric hydraulic thrusters:
| Feature | EB Thrusters (Elhy style) | ED Thrusters (Eldro style) |
|---|---|---|
Design Style | Traditional industrial German/European standard | Modernized version of the original EMG ELDRO design |
Piston Force & Stroke | High-force, frequently customized for heavy-duty stopping (e.g., up to 6,300 N+) | Highly precise and adjustable stroke; renowned for rapid cycle times |
Best Suited For | High duty-cycle applications with frequent start/stop operations | Highly demanding industrial environments (ports, steel mills) requiring exact torque regulation |
