Ed100/6 Series Electro-hydraulic Thruster

The Ed100/6 Series Electro-hydraulic Thruster is a robust and reliable linear actuator widely used for industrial braking and clutch systems. Here is a description of its key features and operation:

Overview:

The Ed100/6 is an electro-hydraulic thruster that converts electrical energy into controlled linear mechanical force. It is primarily designed to actuate brakes on cranes, hoists, conveyors, and other machinery requiring precise and durable motion control.

Key Features:

Electro-hydraulic Principle:​ It uses an integrated electric motor to drive a hydraulic pump. This pump pressurizes oil within a sealed cylinder, which then extends a piston rod to generate thrust. This design combines the power of hydraulics with the control simplicity of an electric motor.

Reliable Thrust Output:​ The series is engineered to deliver consistent and powerful linear force (thrust), suitable for demanding industrial environments.

Simple and Robust Construction:​ It typically features a durable, oil-immersed design. The running gear (motor, pump) operates in an oil bath, which provides effective lubrication, cooling, and protection from contaminants, leading to long service life and low maintenance.

Smooth and Quiet Operation:​ The hydraulic action ensures relatively quiet and cushioned movement compared to purely mechanical systems.

Adjustable Stroke:​ The actuation stroke can often be adjusted to suit specific application requirements.

Mounting Flexibility:​ Designed for easy integration into various brake caliper or linkage setups.

Typical Specifications (General for the Series):

Thrust Force:​ High force output suitable for industrial brakes (exact kN value depends on specific model within the Ed100/6 series).

Stroke:​ Standard linear travel distance (e.g., commonly 60mm, as the "/6" may indicate).

Power Supply:​ Operates on standard AC voltages (e.g., 380V, 415V, 440V 3-phase, 50/60 Hz).

Duty Cycle:​ Designed for frequent operation, often with a high duty cycle (e.g., up to 60% or more).

Fluid:​ Uses hydraulic oil contained within the sealed unit.

Operation:

When power is applied, the electric motor starts and drives the pump. The pump pressurizes the hydraulic oil, forcing the piston to extend. This extension pushes the connected brake mechanism (via a lever or direct linkage) to release the brake. When power is cut off, a spring (either within the thruster or in the brake mechanism itself) returns the piston to its retracted position, automatically applying the brake. This fail-safe design is crucial for safety.

Primary Application:

Its main use is as an actuator for shoe brakes or disc brakes​ on:

Overhead cranes and hoists

Mine winders

Conveyor systems

Railway shunting yards

Other heavy machinery where reliable braking is essential.

Advantages:

High reliability and durability

Low maintenance requirements

Self-contained and sealed system

Provides smooth actuation

Fail-safe spring-return operation (typically)

In summary, the Ed100/6 Series Electro-hydraulic Thruster​ is a classic, heavy-duty actuation device known for its simplicity, power, and dependability in industrial motion control and safety systems.
