— Product Overview

Purpose-Built for Mission-Critical Infrastructure

The YLDG-M series delivers uniform, high-lumen illumination across vast open areas — from highway interchanges to container ports — with minimal maintenance downtime.

Motorized Lifting System

Electric winch with stainless steel cable allows safe lowering of the luminaire carriage for ground-level maintenance — no crane required.

High-Efficiency LED Array

Modular 6× 200W LED fixtures with 180 lm/W efficacy, 5000K daylight output, and Type III/IV distribution optics.

Hot-Dip Galvanized Steel / SS 304/316L

Pole shaft, cross-arms, and carriage hot-dip galvanized per ASTM A123 for corrosion resistance exceeding 25-year service life.

Smart Control Ready

0-10V dimming, photocell input, and optional NEMA 7-pin receptacle for wireless IoT monitoring and scheduling.

— Core Mechanism

Motorized Lifting & Lowering System

The heart of the YLDG-M is its electrically-powered winch mechanism, housed within the pole base. A 1.5 kW motor drives a planetary gearbox through a stainless steel cable and pulley system, enabling a single technician to safely lower the entire luminaire carriage to ground level for maintenance — eliminating the need for bucket trucks or cranes.

1.5 kW three-phase motor with thermal overload protection
316 stainless steel wire rope, 8mm diameter, 6×19 construction
Automatic mechanical brake engages on power failure
Guide rollers prevent cable tangling during operation
Lowering speed: 3 meters per minute (controlled descent)
Manual override hand-crank for emergency operation
Carriage locking mechanism at operating position
Maintenance cycle: < 30 minutes for full lowering and raising

— Light Source

High-Power LED Luminaire Module

Each YLDG=M carries 6 independently aimed LED floodlight modules, delivering up to 216,000 lumens of uniform white light. The modular design allows individual fixture replacement without disrupting the entire system.

6× 200W modular LED floodlights (1200W total per pole)
Luminaire efficacy: 180 lm/W system-level
CCT: 4000K / 5000K selectable (CRA ≥ 70)
L70 rated life: 100,000 hours (TM-21 projected)
Distribution: Type III, Type IV, or asymmetric optics
Die-cast aluminum housing with integrated heatsink
Tempered glass lens with anti-UV coating
Surge protection: 10kV/20kV (line-to-ground)

— Structural Integrity

Pole Shaft & Foundation System

The tapered octagonal pole shaft is fabricated from high-strength Q345B steel plate, seam-welded and hot-dip galvanized for maximum corrosion protection. The multi-section design with flanged connections allows transport and on-site assembly.

Material: Q345B high-strength low-alloy structural steel
Shape: Tapered octagonal (12-sided optional)
Wall thickness: 6mm to 35mm
Wind load rating: up to 160 km/h (Category III)
Seismic rating: Zone 3 / Site Class D
Foundation: Reinforced concrete with embedded anchor bolt cage
Flange connection: 24× M30 hot-dip galvanized bolts
Coating: Hot-dip galvanized per ASTM A123 (85μm min.)

— Applications

Deployed Where Scale Meets Safety

The YLDG-M series is the standard solution for large open areas requiring uniform, high-intensity illumination with minimal fixture count.

Airports & Runways

Apron, taxiway, and cargo area illumination meeting ICAO standards for vertical and horizontal illuminance.

Highway Interchanges

Grade-separated intersections and toll plazas with uniform light distribution eliminating dark spots.

Ports & Yards

Container terminals, logistics yards, and rail facilities requiring 24/7 high-security lighting.

Sports & Events

Stadium perimeter, training fields, and outdoor event spaces with glare-controlled flood lighting.

Container Port Illumination

Multiple YLDG-M units deployed across a major container terminal, providing 30+ lux uniform illuminance across operational areas while reducing energy consumption by 65% compared to legacy HPS installations.

A high mast lighting pole is a tall, heavy-duty lighting structure designed to illuminate large outdoor areas efficiently. Typically ranging from 15 to 50 meters in height, high mast poles provide wide-area coverage with fewer installations, making them an ideal solution for highways, airports, seaports, sports facilities, industrial yards, parking lots, and public squares.

Manufactured from high-quality stainless steel or galvanized steel, high mast poles offer exceptional strength, corrosion resistance, and long service life, even in harsh environmental conditions. Their elevated mounting height allows multiple LED luminaires to be installed on a single crown, delivering uniform illumination while reducing energy consumption and maintenance costs.

Modern high mast systems are often equipped with a motorized lowering mechanism that enables safe and convenient maintenance at ground level. Engineered to withstand high wind loads and meet international safety standards, these poles provide reliable performance and structural stability for demanding lighting applications.

With customizable heights, finishes, and lighting configurations, high mast poles are a cost-effective and durable solution for large-scale outdoor lighting projects.
