Merry Christmas from our team in Seagoville. Many crews slow down or shut down over the holidays, and North Texas winter weather can change fast. Before the break, here are the cold-weather crane habits worth reviewing with your crew.
Watch for fast-moving fronts
A North Texas winter day can start mild and turn cold and gusty within an hour when a front comes through. Those gusts matter more than the temperature. Large loads with a lot of surface area, such as panels, forms or roof units, catch wind like a sail and can swing well outside the planned path.
Check the forecast before the shift and again before any long or high pick. Know the wind limits in your crane's load chart notes and operator's manual, and remember that wind at the boom tip is stronger than what you feel on the ground. If gusts are rising, set the load down and wait; OSHA's rule (1926.1417) expects a competent person to decide what the manufacturer's guidance requires in adverse weather.
Check the ground after freezes and rain
Winter rain soaks the clay soils common around Dallas, and a freeze followed by a thaw can leave ground that looked firm yesterday soft today. Before setting outriggers:
- Look for standing water, mud or frost heave where the pads will go.
- Use proper outrigger pads or crane mats sized for the ground, not scraps of plywood.
- Re-check level during the day; a pad that settles changes the crane's stability.
Ground conditions are covered in 1926.1402, and the controlling contractor has duties there, but the operator is the one who sees it first.
Cold starts and slick surfaces
Cold mornings are hard on machines and people. Follow the manufacturer's warm-up procedure so hydraulic oil reaches operating temperature before you load the crane; sluggish or jerky controls are a sign it is not there yet. Clear frost from windows and mirrors. Check that the load moment indicator and anti-two-block system work after a cold night.
Ice on steps, decks and outrigger beams causes falls. Use three points of contact when climbing on and off, and clear ice before anyone works on the crane. Gloves that keep hands warm but still let you feel the controls are worth paying for.
Securing cranes for the holiday break
When a crane sits for days while the site is empty, a few steps prevent trouble when work resumes:
- Follow the manufacturer's procedure for leaving the crane unattended, including boom position and swing brake or lock.
- Lower or retract the boom where the manual recommends it for expected winds.
- Land the hook block and secure it so it cannot swing into the boom.
- Lock the cab, remove keys and secure the site against unauthorized use.
- Plan a full inspection before the first lift back, not just a quick walk-around.
Shorter days and holiday distractions
December has the shortest days of the year, and lifts that run late can end in poor light. Plan picks so you are not finishing a critical one at dusk, and make sure the signal person stays visible or switch to radios. The holidays also bring distraction: people thinking about travel, family and time off. A short pre-lift talk that names the hazards for the day helps everyone stay focused until the last load is down.
Looking ahead to the New Year
The holidays are a good time to plan next year's training. If your crew needs rigging and signaling skills, the Rigger/Signal Person Certification Level I 28 Hours course prepares for NCCCO Rigger Level I and Signalperson, and the Miller Crane Works Level I Rigger/Signal Person 4 Hours course gives a shorter qualification. For new operators, Mobile Crane Operations Fixed/Swing Cab 120 Hours is the usual start. Company classes explains how employers enroll a group.
From all of us at Miller Crane Works, Merry Christmas, and stay safe on the job.
Winter crane questions
Is there an OSHA wind speed limit for crane lifts?
OSHA's crane rule does not set a single wind speed for all cranes. The limits come from the manufacturer, and a competent person decides how to apply them when weather turns bad.
Do cold temperatures affect crane capacity?
Some manufacturers publish limits or special procedures for operating in very low temperatures. Check the operator's manual and load chart notes for the crane you are running.
What should we inspect when a crane has sat idle over the holidays?
Do a thorough pre-use inspection: wire rope, hook, sheaves, fluid levels and leaks, outriggers, and safety devices such as the load moment indicator and anti-two-block system.
