Are you Winter Ready?

Winter presents a variety of issues for crane operators on construction sites. Reduced daylight, unpredictable weather, and deteriorating conditions all require constant monitoring by crane operators and site managers. The decision to continue or suspend lifting operations is regularly under review and heavily influenced by the need to protect workers and equipment.

With more than 25 years of experience in crane hire, we have seen how sites with robust winter protocols and strong management practices are far better equipped to handle the uncertainties that winter weather brings. Understanding lighting requirements, wind operating thresholds, and operator preparedness will ensure that the correct decisions are made when conditions deteriorate.

In this article, we look at the key considerations for maintaining safe crane operations throughout the winter months.

Lighting Requirements

As winter reduces daylight hours, effective crane lighting becomes essential for maintaining safe operations during early starts and late finishes on construction sites. Tower lights mounted on crane sections illuminate the ground below, improving worker safety and preventing collisions, whilst jib lights enhance load control by eliminating blind spots around the hook and alerting ground workers to crane movements. Aircraft warning lights ensure the crane remains visible to low-flying aircraft in all conditions, day and night. Together, these lighting systems—tower, jib and aircraft warning lights—reduce accident risks, improve visibility for both operators and ground personnel, and enable contractors to work safely and efficiently despite reduced daylight hours.

Wind Speed Thresholds

Before operating any crane, operators must familiarise themselves with the crane manufacturer’s manual, particularly sections covering wind speed limits and operational restrictions. Pre-shift checks should confirm that anemometers and warning systems function correctly, as maximum wind speeds refer to gusting conditions that exceed mean wind speeds. Loads with large surface areas require significantly reduced wind speed thresholds for safe handling, and operators must cease lifting immediately if they feel unable to maintain control, regardless of recorded wind speeds. When wind speeds approach operational limits, place the crane out of service with the jib free to weathervane, allowing the structure to align naturally with wind direction. Establish clear communication channels between operators, ground personnel and site management to enable rapid shutdown decisions when conditions deteriorate.

Rain, Ice and Storm Considerations

Heavy rain reduces visibility and affects load control, particularly when handling sheet materials or loads with significant surface areas that act as wind sails. Water accumulation on loads increases weight unpredictably, whilst wet slings and chains can slip if not properly secured.

Before predicted storms, conduct thorough inspections of all moving parts, braking systems and electrical components. After ice or snow, never attempt operations until the crane has been fully inspected and cleared of ice build-up.

Operator Competency and Winter Awareness

In all cases, the crane manufacturer’s guidelines on operating in windy and stormy conditions should be adhered to. Beyond this, competent operators should recognise when conditions have moved beyond safe working parameters and be prepared to halt lifting operations until satisfied that it is safe to resume. Experienced banksmen play a vital role in winter operations, providing ground-level assessment of conditions that may not be apparent from the crane operator’s cab. Regular communication between operators, slingers and site management ensures everyone understands current weather limitations and agreed thresholds for ceasing work.

Prioritising safety on site during winter months protects the site team and prevents the delays that follow incidents or equipment damage. When winter conditions threaten operational safety, experienced guidance and proper protocols protect both the site’s workforce and project timelines.
