Manufactured to OEM specifications, this spring is engineered for durability, consistent tension characteristics, and resistance to corrosion.
Thwaites Galvanised Handbrake Spring - OEM Number: T9722
Part No.
HMP4277
The Thwaites Galvanised Handbrake Spring (OEM T9722) is a genuine replacement return spring designed for use on a range of Thwaites site dumpers and construction equipment. It forms an integral part of the parking brake mechanism, providing the tension required to assist handbrake operation and ensure correct brake linkage movement during engagement and release.
Manufactured to OEM specifications, this spring is engineered for durability, consistent tension characteristics, and resistance to corrosion. The galvanised finish provides additional protection against rust and environmental exposure, making it particularly suitable for the demanding conditions encountered on construction sites and in outdoor applications.
FUNCTION AND OPERATION
- Provides return tension within the handbrake mechanism
- Assists correct engagement and release of the parking brake system
- Maintains proper brake linkage operation
- Helps prevent brake components from binding or remaining partially engaged
- Supports reliable parking brake performance and safety
- Designed for heavy-duty construction equipment applications
TECHNICAL DETAILS
- OEM Part Number: T9722
- Type: Handbrake return spring
- Function: Parking brake linkage tension and return component
- Application: Thwaites parking brake systems
- Construction: High-tensile spring steel
- Finish: Galvanised for enhanced corrosion resistance
- Design: OEM-configured spring for direct replacement installation
Handbrake springs of this type are commonly used within mechanical parking brake systems to maintain correct linkage movement and braking performance.
TYPICAL APPLICATIONS
Suitable for a range of Thwaites equipment, including:
- Thwaites 3 Tonne dumpers
- Thwaites 5 Tonne dumpers
- Thwaites 6 Tonne dumpers
- Thwaites 9 Tonne dumpers
- Thwaites Power Swivel dumpers
- Mechanical parking brake and handbrake linkage systems
Similar galvanised return springs are widely used throughout construction, agricultural, and industrial machinery where reliable brake operation is essential.
IMPORTANT INFORMATION
Always confirm the correct OEM part number, machine model, and brake system configuration before ordering, as handbrake springs can vary significantly in length, wire diameter, hook design, and spring tension between different machine models and production ranges. A stretched, weakened, corroded, or broken handbrake spring can result in poor brake linkage operation, incomplete brake release, excessive lever travel, or reduced parking brake effectiveness. When replacing handbrake springs, it is advisable to inspect the complete brake linkage, pivots, cables, return mechanisms, and brake components for wear or damage to ensure safe and reliable operation.
