About Electric Hydraulic Thruster

A Fail Safe Electro Hydraulic Thruster is a precision-engineered actuator designed for reliable and secure braking operations in heavy-duty industrial systems such as cranes, hoists, and conveyors. It converts electrical energy into hydraulic thrust to smoothly operate brake mechanisms while ensuring automatic engagement during power failure, providing maximum safety.

Manufactured with robust cast iron or steel housing and high-quality hydraulic components, this thruster guarantees smooth operation, quick response, and long service life even in harsh industrial environments. It is ideal for applications requiring fail-safe performance and continuous-duty operation.

Versatile Industrial Application

The ST 520 Electric Hydraulic Thruster is engineered for use in demanding industrial settings, seamlessly integrating with a wide range of thruster brake frames and assemblies. Its sturdy cast iron construction and efficient cylinder design ensure long operational life and consistent output in tough environments, making it a reliable choice for both new installations and replacement scenarios.

Efficient Performance and Compatibility

With a lifting force of 18 kg and a 51 mm stroke, the ST 520 provides precise and dependable linear motion required for brake actuation. Operating at just 0.4 amps and powered by 415 VAC, its 90-watt motor ensures energy efficiency. Compatibility with BS 148 Transformer Oil aids in smooth, maintenance-friendly operation.

FAQ's of Electric Hydraulic Thruster:

Q: How is the ST 520 Electric Hydraulic Thruster installed in a brake assembly?

A: Installation involves mounting the thruster within the compatible brake frame or assembly using the specified 12.7 mm hole diameter. Ensure the orientation matches the cylindrical shape and secure with appropriate fittings. It's important to connect the electrical wiring to a 415 VAC, three-phase supply, and fill the 2-litre reservoir with BS 148 Transformer Oil or its equivalent before operation.

Q: What benefits does the ST 520 thruster offer for industrial braking systems?

A: The main benefits are its consistent lifting force of 18 kg, compact 349 mm overall height, and efficient power usage at only 90 watts. Its compatibility with various brake frames and use of durable cast iron make it suitable for replacement and new installations, reducing equipment downtime and enhancing system reliability.

Q: Where is the ST 520 commonly used?

A: This thruster is typically used in industrial brake frames or assemblies, especially in heavy-duty applications where reliable and repetitive actuation is required. It is suitable for manufacturers, exporters, and suppliers dealing with thruster brake systems requiring precise linear force.

Q: When should the oil in the hydraulic thruster be checked or replaced?

A: Oil levels and quality should be checked regularly, at least every six months, or according to manufacturer recommendations. Replace the BS 148 Transformer Oil or equivalent when contamination, discoloration, or viscosity changes are observed to maintain optimal performance.

Q: What is the process for ensuring the correct oil level and type in the ST 520?

A: To ensure proper operation, fill the oil reservoir with 2 litres of BS 148 Transformer Oil or an equivalent as specified. Periodically inspect the oil level through the viewing window (if equipped) and top up as necessary. Always use clean oil suitable for hydraulic thrusters.

Q: How does the ST 520 enhance the safety and efficiency of brake systems?

A: The ST 520 delivers reliable, repeatable lifting force for actuating brake mechanisms, reducing manual intervention and wear. Its efficient electrical consumption and robust materials help increase operational safety and minimize maintenance requirements over the service life of the equipment.
