Technical Guide of Cable Protectors
1. Height Verification (Critical Point): The diameter of the largest cable must be smaller than the internal height of the channel. As a rule, a 10% safety margin is left (e.g., if the channel is 30mm high, the cable should not exceed 27mm).
2. Horizontal Space Calculation (Width): The diameters of all cables that must pass through the same channel are summed.
Sum of Diameters + (Number of Cables - 1) x Maneuver Space ≤ Channel Width
Note: Cables are never perfectly straight, so some tolerance is required.
3. Fill Rule (Area): To avoid overheating (especially for power cables), you should never occupy more than 60-70% of the channel's cross-sectional area.
For a quick and easy calculation, we have designed the Technical Wiring Configurator which you can find in this technical section.

The material of a protector affects strength, flexibility, and durability. Here are the differences:
- Rubber (Natural/Synthetic): Elastic polymer with excellent resilience. It absorbs shocks and vibrations, ensuring maximum grip on irregular surfaces.
- TPR/TPE (Thermoplastic Elastomers): Combine the flexibility of rubber with the ease of processing of plastic. They maintain high performance across a wide range of temperatures.
- TPU (Thermoplastic Polyurethane): High-performance, eco-friendly, and recyclable material. It offers significantly superior resistance to abrasion and extreme loads, ideal for heavy-duty industrial applications.
Our ramps are mainly made of Rubber or TPU. TPU offers millimetric precision and is odorless, while rubber remains the optimal choice for maximum resilience and ground stability.
The quality of rubber depends on the percentage of raw (natural) rubber present in the compound:
- High Quality (70% raw rubber): Estimated lifespan ~8 years.
- Good Quality (35% raw rubber - Our Standard): Best compromise between cost and reliability. Estimated lifespan ~5 years.
- Standard/Economy (10% raw rubber): Often contains low-quality recycled plastics. Limited lifespan of ~3 years and a pungent odor.
Factors affecting operational life: Traffic frequency, type of load (static vs. dynamic/braking), and installation environment (UV rays, chemicals, extreme temperatures).
However, it is necessary to opt for a cable protector with a capacity of 10t or higher (Safety Factor) if:
- The passage is frequent (daily).
- The support surface is irregular.
- Maneuvers, braking, or use in extreme environments (oils, acids) are expected.
Please note that markings/warnings or even permits may be required when used on public roads.
A maximum vehicle speed of 5 km/h is recommended.
Regulations: Our products comply with D.M. 17-01-18 (Technical Standards for Construction) and Eurocodes UNI EN 1993 for road loads (Cat G - areas for medium vehicle traffic 30kN-160kN).
Environment: Unlike low-cost products of doubtful origin, the rubber of our ramps comes from specifically treated recycled tires. It does not contain chemicals that act on the endocrine and hormonal systems, nor does it contribute to the variation of soil or water pH. It contains no hazardous ingredients in accordance with EC Regulation No. 1907/2006 - REACH (Registration, Evaluation and Authorization of Chemicals).
