The crew is up on the facade. The basket starts to drift a little. Someone on the radio asks the question nobody wants to answer: “Are we still OK up here?”
If you have hired a boom lift or man lift rental Dubai for tower work, you will face this moment sooner or later. The MEWP wind speed limit has been reached, the programme is tight, and everyone is looking at the supervisor.
At Dream Way, this is one of the calls our rental desk takes most often when the wind picks up on a tower job. Over time we have settled on a simple routine. Below you will find that routine, the numbers that actually matter, and practical ways to keep the day productive while the machine waits on the ground.
What should you do the moment wind goes over the MEWP limit?
When wind exceeds the MEWP limit, stop the task, secure loose items, and lower and stow the platform straight away. Record the reading, keep people clear below, and tell the supervisor. Do not go back up until readings at platform height stay below the rating on the machine plate, typically 12.5 m/s for outdoor machines.
The limit is printed on the machine data plate and in the operator manual. And the reading that counts is the one taken at platform height, not the one taken at the site gate.
A typical call our desk gets on a windy afternoon
A facade contractor working on a Business Bay tower called our desk one afternoon. Their crew was up on a telescopic boom fixing cladding brackets. The handheld reading in the basket kept climbing, and the supervisor wanted to know one thing: could they finish the last panel before coming down?
We hear that question a lot. It usually comes from a good place. The crew is nearly done, the panel is right there, and nobody wants to lose an hour.
Our answer was the same one we always give. Bring the platform down and stow it. No panel goes into the basket in that wind, because the panel is exactly what turns a breeze into a push.
We asked the supervisor to note the readings and the time in the site log. Then we talked through what the crew could do on the ground in the meantime: sorting brackets, marking the next run of fixings, checking the panels that were waiting to go up.
The crew came down without fuss. They did their ground level prep. Later, once the readings at height had settled and stayed down, the operator walked round the machine, tested the controls, and they went back up to finish the run.
Nothing dramatic happened, and that is the point. A calm stop is far cheaper than a damaged machine, a dropped panel or an injured operator.
What is the actual MEWP wind speed limit for a boom lift or man lift?
The 12.5 m/s rating for outdoor machines
Outdoor rated MEWPs are typically designed for a maximum wind speed of 12.5 m/s. That is 45 km/h, or about 28 mph.
This figure comes from the European MEWP standard EN 280 and the international ISO 16368 standard. In North America, the ANSI A92 and CSA B354 standards use the same 12.5 m/s rating, aligned with ISO.
Here is the part people miss. Always use the figure on the data plate and in the operator manual of the actual machine on your site. Some machines, and some configurations of the same machine, carry a lower figure. The plate wins every time.
Indoor only rated machines have a zero wind rating
Some scissor lifts and compact machines are rated for indoor use only. That rating means no wind at all.
So an indoor only machine must not go outside, even on a still Dubai morning. A slab edge, an open podium or a rooftop counts as outside.
Before any of those jobs, check the plate. If the job needs it, ask for an outdoor rated scissor lift instead. We are always happy to confirm the rating on a machine before it leaves our Ras Al Khor yard.
What 12.5 m/s feels like (Beaufort scale)
On the Beaufort scale, 12.5 m/s sits inside force 6, the “strong breeze” band, which runs from 10.8 to 13.8 m/s.
In practice, that is when large branches move and wires start to whistle. It is a useful mental picture. But it is only a rough guide, and feel never replaces a reading from an anemometer.
Why the wind at the top of a Dubai tower is not the wind at the gate
Wind speed increases with height
IPAF notes that wind speed can be around 50% greater at 20 metres than at ground level. On a tower facade, the basket may be working well above that.
Weather app and forecast figures are usually given for 10 metres above the ground. So a forecast that looks comfortable can understate what the platform actually sees. Take your own reading in the basket.
Funnelling between towers in Business Bay, Downtown, Marina and JLT
Tall buildings standing close together do strange things to wind. They shelter one spot and squeeze the air through another.
In districts like Business Bay, Downtown Dubai, Dubai Marina and JLT, the corners of a tower and the gaps between neighbouring towers are where the basket tends to get pushed. One face of the building can feel calm while the corner twenty metres away is gusting hard.
That is why a reading on one side of the site tells you very little about the other side.
Gusts, not averages
A gust is a short, sudden rise above the average wind speed. Crane guidance measures it as a 3 second gust, and that idea is useful for MEWP crews too.
The machine does not care that the average looks fine. It reacts to the gust that hits it. Genie advises against operating in strong or gusty winds for exactly this reason.
So watch the peak reading on the meter, not just the steady number.
Sail loads: panels, glass and signboards
Anything with surface area in the basket increases the wind force on the machine. Cladding panels, glass units, signboards and banners all act like sails.
Manufacturers prohibit increasing the platform surface area or attaching banners and signs. If heavy panels need lifting, a lift plan with mobile crane rental may suit the job better, keeping in mind that cranes have their own wind limits on their load charts.
Step by step: what to do when wind exceeds the limit mid task
- Stop the task and secure loose items (operator). Put the tool down, finish nothing. Clip or bag anything loose in the basket so it cannot fall or blow out. Do not try to fix “just one more” bracket. The decision is made the moment the reading crosses the plate value.
- Lower and retract to the stowed position (operator). Follow the operator manual for lowering and retracting. Move smoothly and keep clear of the facade, because a swinging basket near glass or cladding is how damage happens. Bring the machine fully to its stowed position, not just partway down.
- Tell the supervisor and the HSE officer, and log it (operator and supervisor). Radio the supervisor straight away. Record the reading, the time and the location on the site wind log. That simple record protects the crew and the contractor if anyone later asks why work stopped.
- Keep people clear below and around the machine (ground person or spotter). While the platform comes down, hold the exclusion zone. Nobody walks under the basket or stands in the swing path. Loose debris can come off the facade in strong wind too.
- Wait for readings to settle (supervisor). Do not raise again until readings at platform height stay below the plate value, and the forecast for the next work window is acceptable. A single quiet minute is not enough. Look for readings that hold steady.
- Walk round and test before going back up (operator). Check the machine for damage and for anything that moved. Test the controls from the ground and from the platform. Check the work area below is clear and the outriggers or ground conditions have not changed.
- Call the rental company if anything felt wrong (supervisor). If the machine behaved oddly, an alarm tripped, or you suspect a different machine would suit this exposure better, call us. That is what our 24/7 on site support is for.
Who has the authority to stop work?
The operator in the basket can always come down. IPAF puts it plainly: if you do not feel comfortable, descend from height.
The supervisor and the HSE officer should back that call, not argue with it. An operator who is pressured to stay up in wind is a risk to everyone below.
Our advice to every contractor is the same. Write the stop and restart values into the site lifting or access plan and the risk assessment, so nobody has to debate it on the day.
What if the platform is stuck at height in high wind?
Do not improvise. Follow the site rescue plan that was briefed before the shift.
Use the ground controls or emergency lowering exactly as the manual describes. Then call the rental company. Our desk is available 24/7, and if a unit has a fault, we will arrange support or a swap.
How to keep the day productive when you cannot go up
As one of our team likes to say: “We would rather lose an afternoon with you than send a machine back with damage or have someone hurt.” But losing the afternoon does not have to mean losing the whole day.
Move to the sheltered face or a lower level
Sometimes one face of the tower or a lower level is genuinely within limits. That can keep a crew working.
This is not a loophole, though. The rule is always the reading where the basket actually is. Take a fresh reading at that face and height, and let the supervisor confirm before anyone goes up.
Switch to ground level prep and inside work
Wind time is good prep time. Crews can pre assemble brackets, cut and mark materials, sort fixings, and check panels for the next lift.
Inside work is another option. A spider lift for lobby and atrium work, or a scissor lift used indoors, can keep fit out moving while the facade waits.
Plan the windy part of the day
Many sites find the wind builds as the day goes on. Where the forecast supports it, plan the most exposed lifts for the calmer part of the day.
In summer, the midday break already takes 12:30pm to 3pm out of outdoor work, so careful planning matters even more. Our guide on what to do when summer heat halts operator work on a Dubai site covers that side of the schedule.
Choose the right machine for exposed tower work
The machine choice makes a real difference on an exposed facade. A few things we always talk through with customers:
- Articulated or telescopic. An articulated boom lets the crew work closer to the facade with less exposed outreach. Here is how a jib helps you work close to the facade.
- The outdoor rating and maximum wind speed on the plate.
- Working height with some margin, so the crew is not working at full stretch.
- Platform capacity for people and tools, not for panels the method statement does not allow.
Our boom lift rental in Dubai range includes telescopic and articulated machines, and our man lifts from JLG, Genie and Haulotte run from 8 m to 43 m. Tell us about the tower and the exposure, and we will help you pick.
Practical example: a glazing crew on a Marina podium
Picture a glazing crew planning to fit glass units from a MEWP on an exposed podium edge in Dubai Marina. The morning looks fine from the ground.
Before lifting the first unit, the supervisor sends the operator up with a handheld anemometer and no glass. The reading at height is higher than the ground reading, and the peak keeps jumping.
Glass is a sail load, so the supervisor does not want it in the basket in those gusts. The decision is simple. Bracket and frame work goes first, with no large surfaces in the basket.
The glass units are held back for the calmer window later in the shift, once readings at height have settled and held. The day stays productive. Nobody takes a chance with a large pane in a gusty corner.
That is the whole skill, really. Measure where you work, treat big surfaces with respect, and change the order of the work instead of forcing it.
Wind day checklist for MEWP work on Dubai towers
Run through this before the shift starts:
- Check the machine data plate for the outdoor rating and the maximum wind speed.
- Keep a handheld anemometer in the basket.
- Check the National Center of Meteorology (NCM) forecast and any weather alerts before the shift.
- Agree the stop value and restart value in the toolbox talk.
- No sheets, banners or panels beyond what the method statement allows.
- Assign a spotter and mark the exclusion zone.
- Brief the rescue plan to the whole crew.
- Keep a wind log sheet on site.
- Save the rental desk phone number in the cab and in the supervisor’s phone.
- Use an IPAF trained operator holding a valid PAL card.
Dust often travels with strong wind here, so our guide on what to do when sandstorms disrupt crane and MEWP work in the UAE is worth a read too.
Restart checklist after high wind
Before anyone goes back up:
- Readings at platform height are back under the plate value and holding steady.
- The machine has been walked round for damage and loose items.
- Controls have been tested from the ground and from the platform.
- The work area below is clear and the exclusion zone is back in place.
- The crew has been briefed again on the plan for the rest of the shift.
Frequently asked questions
What is the maximum wind speed for a boom lift?
For outdoor rated boom lifts and man lifts, the maximum design wind speed is typically 12.5 m/s, or 45 km/h. This comes from standards such as EN 280 and ISO 16368. Always follow the figure on the data plate of your machine, because some models and configurations carry a lower rating.
What is 12.5 m/s in km/h?
12.5 m/s is 45 km/h, which is about 28 mph. To convert metres per second to kilometres per hour, multiply by 3.6. Many handheld anemometers can display either unit, so set yours to match the plate on your machine.
Can an indoor rated scissor lift be used outdoors on a calm day?
No. Indoor only means the machine is rated for zero wind. Even a calm Dubai morning can bring a sudden gust at a slab edge or rooftop. If any part of the job is outside, ask for an outdoor rated scissor lift.
Is the wind speed at ground level good enough to decide?
No. Wind increases with height, and IPAF notes it can be about 50% higher at 20 metres than at ground level. Buildings also funnel wind around corners. Always take the reading at platform height, where the basket is actually working.
Do gusts count or only the average?
Gusts count. A gust is a short burst above the average, and the machine reacts to that peak. If the average is under the limit but gusts are pushing past it, treat it as over the limit and bring the platform down.
Who decides to stop MEWP work in wind?
The operator in the basket can always decide to come down if they are not comfortable. The supervisor and HSE officer should support that decision. The best practice is to agree stop and restart values in advance and write them into the site plan.
How long should we wait before going back up?
There is no fixed number of minutes. Wait until readings at platform height stay below the plate value and the forecast for the work window is acceptable. Then walk round the machine, test the controls, and check the area below before raising the platform.
Need a boom lift, man lift or IPAF trained operator for a windy tower job?
Wind on a tower job is not something to fight. It is something to plan for, with the right machine, a trained operator and a team that answers the phone.
That is how we work at Dream Way. We help you pick a machine suited to the exposure, supply IPAF trained operators on request, and run IPAF training in the UAE for your own team. Every machine is checked before it leaves our Ras Al Khor yard, with test certificates and inspection logs kept current.
We offer same day delivery on most equipment across all seven Emirates, plus 24/7 on site support and a swap if a unit has a problem.
