The PU Sidewall Belt is a specialized design engineered to hold, lift, and transport bulk or loose materials along inclined paths or through multi-level transfer points. With its convenient structure and high durability, this belt is an ideal solution for production lines that require stable material flow control, minimized spillage, and optimized operational efficiency.
Structure of the PU Sidewall Belt
The belt consists of the following components:
PU Belt
Made from high-quality polyurethane, offering excellent tensile strength, flexibility, and resistance to oil and grease. PU is non-toxic, easy to clean, and suitable for food processing, pharmaceuticals, agriculture, and certain light chemical operations.
Cleats
Cleats (or flights) are fixed crosswise barriers that form holding compartments on the belt surface. They increase friction, prevent backsliding on steep inclines, and support Z-type or L-type conveyor configurations. Cleats can be straight, angled, or tray-shaped depending on the transport requirement.
Sidewalls
Flexible PU sidewalls run along both belt edges to prevent materials from spilling during elevation. Sidewalls are especially useful for loose products, small items, or steep-angle conveying.
The combination of PU belt, cleats, and sidewalls ensures stable transport on steep inclines, reduces spillage, and maximizes volumetric throughput per cycle.

Advantages of PU Cleated Sidewall Conveyor Belt
- Stabilizes material flow on inclines and prevents backsliding or spillage
- Maximizes volume capacity with adjustable cleat dimensions
- Allows steep-angle, Z-shape, or L-shape conveyor layouts
- Offers flexible material options for cleats (PU, TPU, PE) and attachment methods
Applications
The PU cleated sidewall conveyor belt is suitable for horizontal, inclined, and Z-shaped conveying.
- Food Processing: Transporting vegetables, fruits, grains, snacks, and other food products.
- Pharmaceuticals & Cosmetics: Conveying tablets, blister packs, vials, and small containers.
- Agriculture & Seafood Processing: Moving raw produce, semi-processed materials, or frozen items to upper processing levels.
- Logistics & Packaging: Transporting cartons, pouches, small parcels, and packaged products.
- Electronics & Semiconductors: Handling trays and small components in cleanroom environments; ESD versions available.
- Recycling & Waste Handling: Lifting plastic pellets, metal scraps, and recycled materials to bins or processing stations.
- Construction Material Handling: Transporting sand, gravel, stone powder, and lightweight building materials.
- Packaged Food Production: Moving trays, boxes, and completed goods between production stages.
- Post-harvest Processing: Sorting, cleaning, and transferring agricultural products to subsequent processing steps.

Cleat & Sidewall Design Considerations
- T- or V-type cleats: best for bulk materials
- L-shaped cleats: ideal for flat-bottom products
- Angled or straight layouts: selected based on stickiness, density, and particle size

Operational Guidelines
Daily Operation
Monitor belt tension and noise levels, avoid overloading, and apply slow start/stop settings.
Cleaning
Use neutral detergents and soft brushes, avoid corrosive chemicals, and prevent high-pressure spraying on joints or bonded areas.
Maintenance
Inspect weekly/monthly/quarterly, monitor joints, cleats, sidewalls, pulleys, bearings, and motors. Replace worn cleats or sidewalls early to prevent extended damage.
