 Technical Report

Product Name: Big Truck Solid Rubber Wheel Chock Rubber Tyre Stopper

Model: RBT-250

Manufacturer: RUBASIA RUBBERTECH INDUSTRIES

Country of Origin: Malaysia

Category: Industrial Vehicle Safety Equipment

1. Product Overview

The RBT-250 Big Truck Solid Rubber Wheel Chock is a heavy-duty wheel immobilization block engineered to prevent unintended movement of stationary vehicles such as trucks, trailers, lorries, buses, and construction machinery.
Manufactured from vulcanized industrial-grade rubber, the product ensures maximum grip, high load resistance, and long-term durability under Malaysia’s demanding environmental and industrial conditions.

The RBT-250 model is specifically designed for large trucks and trailers exceeding 20 tons GVW, providing mechanical stability during loading, unloading, parking, or vehicle maintenance operations.

2. Product Identification

3. Physical Dimensions & Properties

4. Material Composition

The RBT-250 is produced from solid vulcanized rubber, a compound formulated for maximum mechanical strength, resilience, and chemical resistance.

4.1. Base Polymer Composition

This material blend results in a dense, non-porous, shock-absorbing solid rubber block suitable for both indoor and outdoor industrial use.

5. Manufacturing Process

1. Material Mixing:
   All raw materials are batch-blended using a Banbury internal mixer for homogeneous compound consistency.
2. Sheet Forming:
   The mixed compound is calendered into rubber sheets, pre-cut into mould-sized blanks.
3. Compression Moulding:
   Each blank is moulded under high pressure (120–150 bar) and temperature (160–170°C) in precision steel moulds for approximately 12–15 minutes.
4. Curing (Vulcanization):
   The rubber undergoes crosslinking reaction to achieve its permanent elasticity and hardness.
5. Demoulding & Finishing:
   Each part is demoulded, edge-trimmed, and surface cleaned. Optional reflective tape or paint marking can be applied.
6. Quality Inspection:
   100% visual inspection for surface defects, followed by random destructive testing for tensile strength and hardness verification.

6. Mechanical & Functional Design

6.1. Structural Geometry

• Wedge Shape: 15° incline angle designed to optimize frictional holding force.
• Base Profile: Cleated, anti-slip design (4 mm depth ridges) for enhanced ground adhesion.
• Tire Contact Surface: Concave curvature (radius ~350 mm) for maximum tire fit and pressure distribution.
• Side Walls: Reinforced with ribbed design to prevent lateral deformation.
• Handle Integration: Dual pre-moulded rope holes (Ø20 mm) for attachment of handle, chain, or rope.

6.2. Anti-Slip Base Analysis

Friction coefficient (μ) on different surfaces (dry and wet):

This ensures stable immobilization performance even under low-traction industrial environments.

7. Performance Evaluation

8. Safety and Compliance

The RBT-250 conforms to relevant international and Malaysian industrial safety guidelines, ensuring compliance for professional and commercial use.

9. Environmental Resistance

10. Functional Applications

10.1. Primary Applications

• Heavy Truck Parking Safety – prevents roll during loading/unloading.
• Trailer Immobilization – stabilizes 20ft/40ft containers at docks.
• Construction Machinery Securing – for cranes, dumpers, and loaders on slope.
• Fuel Tanker Safety – used during refueling to prevent drift.
• Aircraft Ground Equipment – supports tow tractors and baggage vehicles.

10.2. Secondary Uses

• Mechanical workshops, bus depots, industrial yards, logistics warehouses, and military transport hubs.

11. Recommended Usage Guidelines

1. Use minimum two wheel chocks per vehicle (front and rear side of wheel).
2. Place on flat, stable surface with cleated side facing downward.
3. Ensure full contact between tire and curved surface.
4. When used on slopes >10°, apply dual chocks on each tire for redundancy.
5. Store in dry, shaded location after use.
6. Replace after visible wear, cracking, or loss of grip pattern.

12. Durability and Service Life

• Expected operational lifespan: 5–8 years under normal industrial use.
• Maintenance-free design; no repainting or tightening required.
• Rubber retains ≥90% mechanical properties after 1,000 usage cycles.
• Can be recycled at end-of-life through rubber reprocessing facilities.

13. Packaging and Logistics

14. Warranty & Quality Assurance

• Manufacturer Warranty: 12 months against material or manufacturing defects.
• Quality Control Protocol:
  • 100% visual inspection.
  • Random batch hardness test.
  • Monthly tensile & compression validation.
  • Batch traceability via coded mould numbers.

All products are certified “Made in Malaysia” and carry RUBASIA Quality Seal ensuring compliance with ISO 9001:2015 quality system.
