APPLICATION
Electro-hydraulic thruster is a kind of drive control system, which is very compact in structure, and integrates electrical motor, centrifugal pump and oil cylinder. It is widely used as drive mechanism of various drum and disc brakes, and as drive control of various industrial valves, pen stock, directional pendulum and steering (<90°) mechanism and clamping devices. Common applications include:
Cranes & Hoists – For controlled braking in overhead cranes, gantry cranes, and winches.
Mining Equipment – Used in conveyors, elevators, and other mining machinery.
Marine & Offshore – For winches, anchor handling, and deck machinery.
Material Handling – In steel mills, paper mills, and other heavy-duty industrial applications.
Railway & Transportation – For braking in railcar movers and shunting locomotives.
KEY BENEFITS OF PRODUCT
Electro-hydraulic actuation – Combines electric motor control with hydraulic pressure for smooth and powerful braking.
Fast response time – Provides quick engagement and release, ensuring precise braking control.
Self-adjusting brakes – Automatically compensates for brake lining wear, maintaining consistent performance.
High reliability – Designed for heavy-duty cycles with minimal maintenance requirements.
Fail-safe operation – Typically spring-applied and hydraulically released, ensuring braking in case of power loss.
OPERATION CONDITIONS
Temperature Range: Usually rated for -25°C to +50°C (may vary by model). The altitude comply with GB755-2000. When the temperature is lower than -20℃, YH-10 aviation hydraulic oil or heater is required.
Relative humidity: no more than 90%.
Power Supply: 3/AC 380V, 50Hz (60Hz or other special voltage requirements should be indicated in order).
Duty Cycle: Suitable for intermittent (S3) or continuous (S1) duty, depending on application.
Hydraulic Fluid: transformer oil or similar.
Environmental Conditions: Can operate in dusty, humid, or harsh industrial environments (IP55 or higher protection).
Mounting Orientation: Must be installed as per manufacturer guidelines. Thrusters can be installed vertically, horizontally or angular (＞15°). The balancing air house should be set upward.
