Caring Instructions for LED Highmast Systems

A complete maintenance guide for pulley-type and motorised LED highmast systems to ensure long-term performance, safety, and reliability.

1. Introduction

LED Highmast systems are engineered for robust outdoor illumination. However, routine inspection and care are essential to maintain long-term performance, safety, and reliability. Proper maintenance reduces downtime, prevents premature failure, and ensures stable lighting output.

2. Why Regular Care is Important?

• Prevents early component failure
• Reduces corrosion and mechanical wear
• Ensures smooth raising/lowering cycles
• Lowers long-term maintenance costs
• Maintains lighting efficiency
• Improves technician safety

3. Types of Highmast Systems

a) Pulley Type Highmast System

Operates using a manual winch and wire rope. Requires manual lowering during service activities.

b) Motorised Highmast System

Uses an electric winch motor and control panel for fully automated lowering/raising operations.

4. Caring Instructions for Pulley-Type Highmast Systems

4.1. Monthly Inspection

• Check wire rope for rust, fraying, or wear
• Inspect pulleys for smooth rotation
• Verify winch handle movement
• Ensure latches and locking system are working properly

4.2. Cleaning

• Remove dust and mud from winch and base-plate areas
• Lubricate pulleys using industrial-grade grease
• Use anti-corrosion spray on exposed metal parts

4.3. Safety Check

• Technicians must use safety harness
• Check winch brakes before lowering
• Avoid overloading headframe with excess luminaires

5. Caring Instructions for Motorised Highmast Systems

5.1. Electrical System Care

• Inspect motor wiring and terminal tightness
• Check for overheating or unusual noise
• Verify limit switches, MCBs, and contactors

5.2. Mechanical Care

• Check winch drum lubrication
• Inspect gear system and motor bearings
• Ensure proper headframe alignment

5.3. Routine Testing

• Perform complete lowering and raising cycle every 30–45 days
• Ensure smooth motion without jerks

6. LED Luminaires Maintenance

• Clean with dry or slightly damp cloth
• Inspect gaskets to maintain IP66 protection
• Check for cracks, rust, or loose brackets
• Verify Surge Protection Device (SPD)

7. Pole & Foundation Care

• Check for rust, peeling galvanization, or dents
• Apply zinc-rich primer on rusted sections
• Inspect anchor bolts and tighten if needed
• Ensure foundation water outlets are clear

8. Wire Rope & Latch Mechanism Care

• Replace wire ropes every 2–3 years
• Check latching system for proper locking
• Lubricate pulleys bi-monthly

9. Safety Guidelines for Technicians

• Perform maintenance during daytime
• Barricade the area before lowering mast
• Wear PPE: helmet, gloves, safety shoes, harness
• Avoid working during heavy wind or rain
• Disconnect electricity before panel inspection
