If you have a standard UK driving license, you are legally able to drive a cherry picker that weighs under 3 and a half tons. On top of this, if you acquired your driving license before 1994, you are able to operate cherry pickers that weigh up to 7.5 tons. To operate heavier, more specialised machinery, you must undergo sufficient training. ACS Access recommend that the operator is competent, including any relevant training, before driving any cherry picker or operating a boom lift.
