Shallow Mount Electro-Hydraulic Automatic Bollard

The YD-S804D is an advanced shallow-mount electro-hydraulic automatic bollard designed for heavy-duty traffic control and high-security access protection. Featuring an innovative dual-layer column structure with a high-hardness steel interior and a rust-proof 304 stainless steel surface, this automatic rising bollard is engineered to reliably withstand the passage of 40-ton container trucks. With a pre-buried sleeve height of only 768±5mm, it reduces installation costs and deep excavation complexity, while its one-piece molded PP+PE sleeve, IP68-rated chassis, and high-capacity bottom drainage system (drain port ≥50mm) ensure maintenance-free performance in any environmental condition.

Innovative Shallow Mount Design with Electro-Hydraulic Drive

Powered by a reliable electric-hydraulic drive system, this automatic bollard requires a pre-buried height of only 768±5mm. It seamlessly adapts to complex road conditions, significantly reducing civil excavation costs and construction complexity, making it an ideal choice for retrofit projects where deep burial is restricted.

Advanced Dual-Layer Material Optimization for Maximum Hardness & Rust Prevention

The rising column engineering utilizes a high-performance coaxial structure: the inner layer leverages high-density structural steel to provide the extreme mechanical hardness required to withstand up to 40 tons of vehicle impact, while the outer surface is wrapped in authentic 304 stainless steel (including a 6±1mm thickness top cover plate) to guarantee premium all-weather rust resistance.

One-Piece Molded Modified PP+PE Protective Sleeve

Unlike traditional iron sleeves that rot underground, the underground outer enclosure is constructed using premium modified PP+PE plastic through one-piece mold injection. Featuring a 6mm structural wall thickness and heavily reinforced ribs, this 3-section heavy-duty sleeve delivers exceptional corrosion and aging resistance, dramatically extending the equipment's underground operational lifespan.

High-Capacity Bottom Drainage System

To survive severe rainstorms and wash-down road environments, the bollard chassis base incorporates an integrated bottom drainage mechanism. Equipped with a drain port diameter of ≥50mm and a robust drain port wall thickness of ≥4mm, it ensures rapid and effective water discharge to maintain consistent IP68 waterproof and dustproof protection.

Rapid Lifting Response & Fail-Safe Emergency Protections

Engineered for high-traffic entry control, the bollard achieves a rapid rising time of ≤4s and a fast lowering time of ≤2s to optimize vehicle throughput efficiency. It supports instant emergency stops during operation and features a built-in backup power supply to automatically enable emergency descent during sudden power outages, keeping critical safety lanes unobstructed.

Q1: What installation environments is this bollard suitable for?

A: This bollard is suitable for retrofit projects with complex underground utilities or where deep excavation is difficult. Its shallow foundation design helps reduce civil works complexity and installation costs.

Q2: Why is the sleeve not made of traditional steel?

A: The sleeve is made of modified PP+PE with integrated reinforcing ribs. Compared to traditional steel sleeves, it offers improved corrosion and aging resistance, helping extend the service life of underground components and reduce long-term maintenance concerns.

Q3: Will heavy rain or standing water affect operation?

A: This bollard features an IP68 dustproof and waterproof rating, combined with a bottom drainage system (drain port ≥50mm). Together, they support stable operation in rainy, water-prone, or wash-down environments.

Q4: Can the 40-ton load capacity handle daily high-frequency passage of heavy vehicles?
A: Absolutely. The column utilizes a high-strength composite engineering design: the inner layer leverages high-density steel to provide the extreme mechanical hardness required to withstand 40-ton container trucks, while the outer sleeve is wrapped in premium 304 stainless steel to ensure long-term rust resistance. This dual-layer approach delivers maximum physical durability and all-weather protection at a highly cost-effective investment level.

Q5: Is the lifting speed noticeable in daily use?

A: Rising time ≤4s and lowering time ≤2s. The faster lowering speed helps vehicles exit quickly, making it suitable for entrances where traffic flow efficiency matters. The hydraulic drive also provides smooth movement.

Q6: What happens during a power outage? Will the bollard stay stuck in the raised position?

A: The bollard includes a backup power supply that enables emergency descent during a power failure to keep the passage clear. Emergency stop is also supported during operation for on-site control.
