Part 1: Core Systems Winterization Checklist

1. Engine & Cooling System: The Heart of Reliability

The engine is most vulnerable during cold starts. Ensure its protection by:

• Switching Fluids: Replace engine oil with a lower-viscosity, winter-grade oil. Verify that your engine coolant is a 50/50 mix with a freezing point 10-15°C below local minimums.
• Proper Warm-Up: Idle for 5-10 minutes, then operate crane functions without load until hydraulic fluid reaches 50-80°C 
• Additional Care: Use radiator covers and inspect belts for cold-weather cracks.

2. Hydraulic & Drivetrain: Ensuring Smooth Operation

Thick fluid can cause jerky movements and damage pumps. Manage it with:

• Winter-Grade Oils: Switch to hydraulic and gear oils formulated for low-temperature operation.
• Moisture Management: Periodically drain water from the hydraulic tank reservoir to prevent ice blockages.

3. Electrical System & Battery: Power in the Cold

• Battery Maintenance: Clean terminals and test charge. Disconnect the negative terminal if stored for >2 weeks.
• Inspect Wiring: Check for brittleness in wiring harnesses caused by freezing temperatures.

4. Structure, Wire Rope & Tires: Mechanical Integrity

• Lubrication: Use calcium- or lithium-based cold-weather grease to resist water wash-out.
• Wire Rope Care: Use specialized lubricants to prevent internal corrosion.
• Tire Pressure: Check bi-weekly; cold weather causes significant PSI drops.

Part 3: Special Winter Operating & Storage Notes

Pro Tip: Avoid pressure washing at sub-freezing temperatures to prevent ice from locking critical mechanisms.

• Storage: Park on level ground with outriggers extended (if possible) and use wheel chocks.
• Daily Inspection: Always perform a visual walk-around and no-load operational cycle.
