The aerial lift CACES is the common name of the R486 CACES, which covers mobile elevating work platforms. In its theory test, the operation theme alone is worth 54 points out of 100, and you need at least 27 correct answers in it to pass. It gathers the situations behind serious accidents: an operator trapped between the guardrail and a structure overhead, a platform tipping on soft ground, on a slope or at the edge of a trench, wind above the limit on the plate, getting too close to a power line, or a person stuck at height who has to be brought down with the emergency controls. The set above draws twenty questions from that theme, marked after each answer. To choose the category, A for vertical lift or B for multi-directional lift, the small tool starts from the type of platform. The R486 CACES is valid for 5 years.

The syllabus of this theme is long, but it revolves around four questions: can the platform tip over, can the operator fall or be crushed, can something fall on someone below, and how do you rescue the operator at height. Every question in the set ties back to one of them.

Before going up

  • Check the ground: bearing capacity, slope, trenches, manholes, and set outriggers on spreader plates where fitted.
  • Cordon off the area below so nobody walks under the basket.
  • Spot overhead obstacles: beams, power lines, overhead cranes.
  • Check the wind against the plate limit, and the rated load in the basket, people and tools included.

Questions operators and candidates ask

At what wind speed must an aerial lift stop?

The limit is the one the manufacturer writes on the platform’s plate, often around 12.5 m/s for models usable outdoors; some platforms are designed for indoor use only and tolerate no wind at all. An anemometer or local weather data helps decide, and a gust counts as much as the average wind.

Who can bring a platform down if the operator is taken ill?

Someone on the ground trained on the emergency controls of the platform in use. That is why the operator does not work alone at height: someone on the ground knows where the emergency controls are and how to lower the basket. The recommendations make this rescue organisation knowledge that the test assesses.

Can I climb out of the basket at height?

No, except under a specific procedure set by the risk assessment and the manual, with an external anchor point. As a rule, the operator stays inside the platform, does not climb on the guardrail and adds neither ladder nor stepladder in the basket to gain height.

How many operation questions must I get right in the aerial lift CACES?

At least 27 out of 54, half the theme rounded up, on top of an overall total of at least 70 points out of 100. As the theme is long, a well-prepared candidate reaches it easily; it is the short themes that fail people, especially maintenance at 6 points.
