# Heat, Rain, Wind and Cold: Operating Access Equipment Through Australian Weather

Western Sydney gives access equipment every season: 45-degree January slabs, February downpours, August westerlies. Each one changes what a machine can safely do. This guide covers the four conditions that actually stop or slow elevated work, and how we plan hires around them.

## Wind: the hard limit

Every EWP has a maximum in-service wind speed in its manual, commonly 12.5 m/s (about 45 km/h) for outdoor-rated scissors and booms, and lower for some machines and configurations. Above the rated wind, elevated work stops: wind load on a raised platform acts on the machine’s stability in a way ballast cannot argue with. Two things catch people out: gusts count (not just average speed), and the wind at 10 m is stronger than at ground level. Indoor-only machines, most compact electric scissors, are rated for zero wind: still air, or the machine stays inside. A cup anemometer on site costs less than an hour of downtime and removes the argument.

## Rain: ground and grip

The machine itself tolerates rain better than the site does. Wet weather softens unsealed ground, yesterday’s firm gravel is today’s bog, so rough-terrain and tracked machines need their access route re-walked after heavy rain, and any outrigger or wheel loading on soil rechecked. Platforms, ladders and steel get slippery; charging connections must stay dry; and electric slab machines should not sit exposed in driving rain. Lightning ends elevated work immediately, full stop.

## Heat: machines and people

Batteries age fastest in heat: charging a hot battery bank in a 40-degree shed shortens its life and its afternoon runtime. Park and charge machines in shade where possible. Hydraulic systems run hotter and can slow or derate on sustained duty; diesel engines need their coolant checked like any plant. The bigger risk is the operator, an elevated platform over a slab is a radiant oven, so plan work for mornings, shade breaks and water. None of this is exotic: it is the same heat plan the rest of the site runs, applied at height.

## Cold: the slow morning

Sydney cold is mild by machine standards, but a 2-degree Berkshire Park morning still shows up: battery capacity drops temporarily, so a machine that ran all day in March feels short in July; diesel engines want their glow cycle and a minute of warm-up; and frost on a platform floor is a slip hazard until it burns off. Plan the first lift of a winter morning ten minutes later and the day runs normally.

## Planning a weather-exposed hire

- Check the machine’s rated wind speed in the manual before booking exposed work, not after the westerly arrives
- Have an indoor task list ready for wind and rain days
- Re-walk unsealed access routes after heavy rain before the machine moves
- Charge overnight, under cover, every night: heat and cold both punish neglected batteries
- Build weather days into the hire length rather than paying for a machine that cannot legally work

## FAQ

What wind speed stops a scissor lift? The machine’s manual states its maximum in-service wind speed, commonly around 12.5 m/s (45 km/h) for outdoor-rated machines, and zero for indoor-only electrics. The plate and manual govern; if you do not know the figure, ask us for the machine’s rating.

Can I leave the machine outside overnight in rain? Parked and lowered, generally yes for outdoor-rated machines, but charge connections must be protected, and we will tell you anything model-specific at handover.

Does weather extend my hire? Tell us when weather stalls the job, options depend on the booking, and asking on the rain day beats asking at off-hire.
