High-Efficiency Leaf Spring Conveyor for Material Handling

Product Description

Y36 Leaf Spring Conveyor

The Leaf Spring Conveyor is a vibratory conveying system that utilizes high-strength elastic steel leaf springs as both load-bearing and drive components. Specially engineered for harsh industrial environments—such as high temperature, heavy load, and dusty conditions—it is widely used in foundries for post-shakeout casting transfer, in heat treatment lines for hot part handling, and in forging shops for billet transport. Capable of continuous operation at temperatures up to 600°C, it requires no lubrication, features no vulnerable bearings, and offers simple structure, smooth conveying, minimal maintenance, and exceptional service life.

Working Principle

Driven by an electromagnetic vibrator or eccentric motor exciter mounted beneath the trough, the leaf spring assembly undergoes controlled elastic deformation, causing the conveyor trough to oscillate with small amplitude in a specific direction. Material advances along the trough via inertial "micro-hopping" motion—ensuring continuous, smooth, and low-impact transport.
Because the leaf springs simultaneously provide support, energy storage, and vibration damping, the unit eliminates the need for rollers, chains, or bearings—solving common issues like jamming, wear, and lubrication failure faced by conventional conveyors in hot, dusty environments.

Key Advantages

High-Temperature Resistant & Versatile
Standard model: ≤400°C; high-temp version: up to ≤600°C—capable of directly conveying red-hot castings or forgings without pre-cooling.

Lubrication-Free & Maintenance-Light
No bearings, chains, or gears requiring lubrication—eliminates failures caused by grease carbonization at high temperatures and drastically reduces maintenance.

Smooth & Quiet Operation
Elastic leaf springs absorb shock and dampen vibration—ensuring quiet, stable conveying with noise levels ≤75 dB(A), improving workplace conditions.

Compact & Flexible Installation
Modular design supports horizontal, inclined (≤15°), or curved layouts—easily integrated with shakeouts, cooling drums, shot blasters, etc.

Energy-Efficient & Long-Lasting
Power consumption is only 30–50% of equivalent chain or roller conveyors. Leaf springs last 5–8 years; overall design life ≥10 years.

Typical Applications

The leaf spring conveyor excels in applications demanding high-temperature tolerance, cleanliness, and minimal maintenance. In foundries, it's commonly used to transfer castings from shakeouts to shot blast machines—preventing impact damage. In heat treatment lines, it conveys parts before and after quenching, enduring repeated thermal shocks. In forging plants, it transports red-hot forgings directly from dies to trimming or straightening stations—fully automated and operator-safe.
