A raising and lowering high mast lighting system allows the floodlight ring to move between the mast head and ground-level maintenance position. Jieyao manufactures project-specific systems for ports, highway interchanges, logistics yards, airports, parking areas, industrial sites and stadium surroundings.
The complete supply can include the polygonal galvanized mast, lowering light ring, LED floodlights, electric winch, emergency manual drive, wire ropes, pulleys, headframe, mechanical locking system, power cable, control equipment, base plate and anchor-bolt cage. Final configuration is calculated from mast height, ring weight, fixture quantity, fixture EPA, wind criteria and the owner's maintenance procedure.
| System element | Project option | Selection basis |
|---|---|---|
| Mast height | Common project range 20–45m | Lighting calculation, site constraints and structural design. |
| Mast body | Tapered polygonal steel sections | Wind load, steel grade, equipment EPA and transport length. |
| Light ring | Circular, polygonal or custom frame | Floodlight quantity, brackets, cable routing and exposed area. |
| Drive | Electric winch with manual emergency provision | Ring mass, lifting travel, safety factor and site power. |
| Suspension | Project-designed wire ropes and pulleys | Working load, redundancy, corrosion environment and inspection access. |
| Operating support | Mechanical latching at mast head | Supports the ring in service and defines correct engagement. |
| Lighting | Multiple LED floodlights with selected optics | DIALux layout, lux, uniformity, glare and spill-light limits. |
| Surface protection | Hot-dip galvanizing; optional paint system | Design life and inland, industrial or coastal corrosivity. |
Actual operation must follow the supplied manual. Personnel should be trained, the exclusion zone controlled and the equipment inspected at the specified intervals.
The number of floodlights should be determined from the required maintained illuminance and uniformity. Jieyao can model the site using project coordinates, mast positions, aiming constraints and luminaire photometric files. The resulting ring arrangement is then coordinated with the structural design.
Wind analysis must include the complete ring, luminaires, brackets, cables and accessories. Pole sections, overlap lengths, plate thickness, base plate and anchor bolts are designed from the approved loading basis. Foundation reactions are provided so the local civil engineer can verify the concrete design with the geotechnical report.
A lowering system reduces routine work at height but still requires planned inspection. The owner should check wire ropes, terminations, pulleys, winch brake, gearbox, electrical cable, limit functions, guides, fasteners, corrosion and latch engagement. Inspection intervals depend on the operating environment, frequency of use and project standard.
Jieyao supports mast cutting, forming, welding, trial assembly, dimensional inspection and surface-treatment coordination at its Yangzhou production base. The company was formally established in 2017 and has 15 years of lighting-industry experience, a 10,000-square-metre production base and 35 employees.
The arrangement is project-specific and can be designed for common 20–45m high mast systems. Height alone does not determine suitability; ring load, internal space and the complete structural design must be checked.
An emergency manual operating provision can be included when specified. The required method should be agreed before production.
A properly designed mechanical latching system supports the ring at the operating position. The exact load path and engagement method are defined by the approved system design.
Quantity depends on the lighting calculation and on ring weight, EPA, wind loading and structural capacity. There is no safe universal number.

Our structural designs are based on local wind data. Standard designs withstand winds up to 160km/h (45m/s), with reinforced options for hurricane-prone regions.
It depends on the mounting height and required lux levels. Generally, for a 25-30m pole, high-power LED floodlights ranging from 400W to 1000W are recommended.
High mast light refers to poles typically 20m (65ft) or taller. It is widely used in airports, seaports, highways, stadiums, and logistics hubs to provide uniform illumination over a vast area.
Q345B has higher yield strength, allowing taller, slimmer poles to remain safe while reducing weight and improving wind performance.
Yes. For coastal cities, we provide anti-corrosion powder coating that meets 500-1000 hours of salt spray test requirements.
High mast poles are designed for large-area outdoor lighting, and their height usually depends on the size of the space that needs to be illuminated.
We use high-strength carbon steel such as Q235B or Q345B, bent into polygonal shapes (usually 12 or 16 sides) and hot-dip galvanized both internally and externally.
Raising & Lowering systems feature an electric winch to lower the light ring to ground level for maintenance. Fixed systems require a bucket truck or ladders for servicing.
It consists of an electric winch, stainless steel wire ropes, pulleys, and an automatic latching mechanism. Once reaching the top, the ring locks mechanically to relieve tension from the ropes.
No. Our systems feature an automatic mechanical latching system and safety brakes to ensure the ring stays secure even without rope tension when in the locked position.
Yes. Each pole is equipped with a lightning rod at the top and dedicated grounding bolts to connect to the foundation grounding system.
We use professional asymmetrical optical lenses (such as Type IV or Type V) to ensure uniformity over large areas and minimize glare.
Through shields and precise light distribution design, we confine excess light to the target area, reducing interference for the surrounding environment and drivers.
A concrete foundation must be poured based on pole height and soil conditions. We provide detailed foundation drawings and anchor bolt cages.
In standard outdoor environments, hot-dip galvanizing provides rust protection for over 25-30 years without requiring additional painting.
Yes. Due to height limits, poles over 20m are typically split into 2-3 telescopic sections for convenient shipping in 40ft containers.
No. Sections are joined via overlap (telescopic fit) using gravity or hydraulic force. This mechanical joint is more flexible and fatigue-resistant than welding.
Yes. Our professional lighting design team provides free Dialux simulation reports based on your site’s CAD drawings to optimize lighting layouts.
Yes, we have extensive project references in the Middle East, Southeast Asia, and South Africa. We can provide photos and technical parameters upon request.
We typically offer a 10-year warranty on the pole structure and a 5-year warranty on the LED fixtures and lifting systems.
Yes. Our light rings can be customized with brackets to accommodate CCTV cameras or other security sensing devices.
EPA refers to the Effective Projected Area of the pole and fixtures under wind pressure. It is a critical parameter for calculating structural safety.
Technically yes, but due to high power consumption, very large solar arrays and battery banks are required. We typically recommend grid-tied or hybrid systems.
We use high-quality stainless steel or plastic-coated wire ropes and recommend regular greasing during annual inspections.
Yes. With intelligent control systems, you can remotely adjust brightness and scheduling to maximize energy savings.
