An electro-hydraulic thruster brake uses an electric motor-driven impeller to create hydraulic pressure, which moves a piston connected to the brake arm. When powered, the brake releases; when power is off, the brake engages smoothly through the brake shoes, which are designed for self-alignment and efficient cooling. The use of high-quality compression springs ensures reliable brake application. The brake is designed to work with a 400/440V three-phase AC power supply, making it suitable for industrial applications.
An electro-hydraulic thruster
brake is a device designed to apply a consistent braking force to
machinery or equipment. It combines hydraulic and electrical technologies
to ensure smooth and reliable braking.
Components
and Operation
Power Supply and Impeller:
When the brake is powered on,
an electric motor drives a centrifugal impeller. This impeller rotates
within the hydraulic system, drawing hydraulic oil from a low-pressure
area and pushing it to a high-pressure area within the brake unit.
Hydraulic Pressure and Piston:
The pressure created by the
rotating impeller is transferred to a piston inside the brake unit. This
piston is directly connected to the brake’s operating mechanism.
Brake Arm and Brake Release:
The piston is linked to an arm
that moves when hydraulic pressure is applied. As the piston extends due
to the pressure, it pushes the brake arm, causing the brake mechanism to
open or release, which disengages the brake.
Brake Application When Power is
Off:
When the power is turned off,
the hydraulic pressure is released. This allows the piston to retract,
which engages the brake. The brake shoes press against the drum, applying
the braking force smoothly and effectively.
Self-Aligning Brake Shoes:
The brake shoes are designed
to self-align, meaning they adjust automatically to ensure even contact
with the brake drum. They are fitted with high-quality brake linings that
have a larger cooling surface. This design improves heat dissipation and
enhances braking efficiency.
Compression Springs:
High-quality compression
springs made from premium spring steel are used to provide the necessary
force to engage the brake when the power is off. These springs ensure
that the brake applies firmly and consistently.
Electrical
and Mechanical Specifications
Power Supply:
The thruster brake operates on
a 400/440V three-phase alternating current (AC) supply. This
specification indicates compatibility with standard industrial power
systems.
Sturdy Construction: Rigid welded design with
easy-to-access mounting.
Compact and Stylish: Sleek, space-saving design
with an attractive appearance.
Durable Components: Robust thruster and materials
ensure reliable, long-term operation.
Efficient Force Distribution: Design optimizes the
distribution of braking forces.
High-Temperature Resistance: Brake shoes are heat-resistant
to prevent overheating.
Ease of Maintenance: Brake shoes are designed with
a 70-degree angle for easier replacement and maintenance.
Quality Springs: Compression springs are
heat-treated for optimal hardness; multiple springs are used as needed for
proper braking torque.
Versatile Use: Suitable for hoists, cranes,
winches, elevators, and various industrial applications.
