Summary: Electro-hydraulic thrusters are compact, motor-driven centrifugal pump units (often used in pairs with crane brakes) that enable smooth, fail-safe braking for cranes, hoists.
Overview:
The Ed thruster is an electro-hydraulic actuator designed for industrial braking systems, functioning to open brakes when powered and apply them via internal springs during power loss. It combines a motor, pump, and cylinder into a compact unit, offering high reliability, smooth operation, and high switching frequencies.
Elemental functions:
Fail-Safe Operation: In the event of a power outage or failure, the piston retracts, causing the brake to close immediately.
Operating Principle: Switched-on state creates hydraulic pressure that lifts the piston, releasing the brake (ELDRO ON = BRAKE OPEN).
High Duty Cycle: Capable of up to 2,000 cycles per hour, making it suitable for demanding industrial environments.
Adjustable Timing: Lifting and lowering times can be adjusted through optional valves.
Durability: Self-lubricating design ensures low wear and long service life.
