Winter Operation Tips for Truck Mounted Cranes

Operating truck mounted cranes in winter conditions requires additional precautions to ensure both safety and equipment longevity. Cold temperatures affect hydraulic fluid viscosity, steel strength, and ground conditions -- all of which have a direct impact on crane performance.

Before starting work, always allow the hydraulic system to warm up for at least 10-15 minutes at idle. Cold hydraulic oil is thicker and flows poorly, which can cause sluggish movements and increased wear on pumps and valves. Consider switching to low-temperature hydraulic fluid (ISO VG 22 or VG 32) for sustained cold-weather operations.

Ground conditions change dramatically in winter. Frozen ground may seem stable, but thawing soil beneath the surface can give way under outrigger pressure. Always use outrigger pads with larger surface area in winter conditions. If operating on snow or ice, check the ground beneath for hidden soft spots.

Steel becomes more brittle at low temperatures, which increases the risk of structural failure under sudden loads. Avoid shock loading at all times, and reduce the rated capacity by 10-15% in extreme cold (below -10°C). Inspect wire ropes and hooks carefully for cracks before each shift.

Electrical systems and batteries are also affected by cold. Ensure batteries are fully charged and connections are clean. Anti-freeze levels should be checked in all engine coolant circuits. Keep all grease points well-lubricated with cold-rated grease to prevent seized joints.

Finally, operator comfort and safety are essential. Ensure cab heaters are working, windshields are clear, and operators have adequate cold-weather PPE. Reduced daylight hours mean work lights should be checked and functioning properly before every shift.
