TWZB-200 Foot Operated Hydraulic Drum Brakes

TWZB-200 foot operated hydraulic drum brakes

The TWZB-200 is a foot-operated, normally-open drum brake. It is a mechanically actuated braking system designed for applications where human power is sufficient for braking requirements.

The model number breakdown is as follows:

TWZ: The series designation for Foot-Operated Drum Brakes.

B: A variant of the TWZ series, featuring an improved linkage mechanism.

200: The Brake Wheel Diameter of 200 mm.

💡 Key Features & Characteristics

Foot-Operated & Normally-Open:

Operation: This is a normally-open brake, meaning it does not apply any braking force when at rest. Braking is initiated by the operator pressing a foot pedal.

Actuation: The force from the pedal is transmitted via a steel wire rope to the brake's lever system, which then forces the brake shoes against the drum.

Release: When the foot pedal is released, springs retract the brake shoes, disengaging the brake.

Self-Equalizing Mechanism:
The "B" variant features an interlocking equalizing device. This mechanism automatically ensures that both brake shoes retract and apply with equal force, preventing uneven wear and one-sided dragging on the brake wheel.

Maintenance-Free Pivots:
The main pivot points of the linkage are equipped with self-lubricating bearings. This design eliminates the need for regular greasing, reducing maintenance requirements and ensuring smooth operation.

Easy Pad Replacement:
The brake linings (shoes) are designed with a card-mounted (snap-in) structure. This allows for quick and easy replacement of worn pads without the need to disassemble the brake arms.

Application-Specific Design:
This brake is specifically intended for the deceleration and braking of medium and small-sized crane travel mechanisms (e.g., the bridge or trolley of an overhead crane).

🏭 Typical Applications

The TWZB-200 is used in applications requiring simple, manual braking control:

Cranes & Hoists: Primarily for the travel (motion) mechanisms of small to medium-sized cranes.

Conveyors: Manual stopping of smaller conveyor systems.

General Machinery: Any equipment where a simple, human-powered brake is adequate for stopping or holding a load.

📋 General Technical Specifications

表格

Note: The TWZB-200 is a purely mechanical device and does not require any electrical or hydraulic power source. The braking force is directly proportional to the force applied to the foot pedal (specified as 320-370 N for the series). Ensure the mounting base is strong enough to handle the reaction forces during braking.
