AC Solenoid Brake – Product Description

An AC Solenoid Brake is an electromagnetically operated brake designed to stop or hold the motion of rotating machinery such as motors, cranes, hoists, and conveyors. It operates on alternating current (AC) and uses a solenoid coil to control the braking action.

When power is applied, the solenoid coil is energized, lifting the brake armature and releasing the brake. When power is cut off, the spring-loaded mechanism engages, pressing the brake shoes or pads against a rotating drum or disc, bringing it to a stop. This fail-safe design ensures that the brake is always applied during power failure, enhancing operational safety.

Key Features:

• Fail-safe operation: Brake engages automatically when power is lost

• Fast response time: Quick braking and release for efficient stopping

• Durable construction: Designed for continuous industrial use

• Easy installation and maintenance

• Available in multiple torque ratings and voltages

Applications:

• EOT cranes and hoists

• Elevators and lifts

• Conveyors and material handling systems

• Machine tools and textile machinery

• Packaging and printing equipment

Typical Specifications:

• Voltage: 230V / 415V AC, 50 Hz

• Torque Range: 3 Nm to 1600 Nm (varies by model)

• Mounting: Flange or foot-mounted

• Manual Release: Optional for emergency use

Thruster Brake for EOT Cranes – Product Description

A Thruster Brake is an electro-hydraulic braking system commonly used in Electric Overhead Travelling (EOT) cranes to provide reliable and automatic braking during load handling operations. It consists of a spring-loaded brake mechanism and an electro-hydraulic thruster that releases the brake when energized.

In the event of power failure or emergency, the brake automatically engages due to spring force, making it a fail-safe solution. Designed for heavy-duty industrial applications, thruster brakes are ideal for frequent start-stop operations and harsh working environments.

Key Features:

• Fail-Safe Operation: Brake applies automatically on power loss, ensuring safety.

• Electro-Hydraulic Thruster: Provides smooth and efficient brake release using fluid pressure.

• Robust & Durable Construction: Suitable for heavy-duty and continuous operations.

• Low Maintenance: Simple design with minimal moving parts.

• Adjustable Torque: Braking force can be adjusted to suit application needs.

Main Components:

• Brake Drum: Connected to the motor or gear shaft.

• Brake Shoes with Linings: Press against the drum to apply braking force.

• Spring Mechanism: Ensures automatic engagement when the thruster is de-energized.

• Electro-Hydraulic Thruster: Lifts the brake shoes off the drum during normal operation.

Applications:

• EOT Cranes (Bridge and Gantry types)

• Hoists and Winches

• Conveyors

• Steel plants, Foundries, and Ports

• Material Handling Systems

Technical Specifications (Typical):

• Thruster Voltage: 415V AC / 3 Phase / 50 Hz

• Brake Torque Range: 15 Nm to 1000 Nm or more

• Mounting: Foot-mounted / Flange-mounted

• Operating Temperature: -10°C to +50°C

• Standards: Conforms to IS: 3177 / IS: 4137 (for crane applications)

A pneumatic clutch brake unit for a power press is a combined system that uses compressed air to engage the clutch for machine operation and apply the brake for stopping or holding. This unit plays a crucial role in ensuring accurate, efficient, and safe operation of mechanical power presses used in stamping, punching, forming, or other metalworking processes. Key Functions: Clutch Engagement: Transmits power from the motor to the press flywheel, enabling stroke movement. Brake Application: Stops and holds the crankshaft immediately after the clutch disengages to ensure operator safety and precision. Quick Response: Fast engagement and release for high-speed, repetitive operations. Main Components:
