Do you need a high-altitude permit for high-altitude work on the climbing vehicle: The question of whether a high-altitude permit is required for work on the climbing vehicle is actually not a simple yes or no answer. This depends on the specific operating environment and safety requirements.
First of all, we need to be clear about what aerial work is. Generally speaking, all operations carried out at a height of more than 2 meters (including 2 meters) from the fall height datum are called aerial work. As a platform that can be raised for work, if its height exceeds this standard during use, then in accordance with relevant regulations, the operator needs to hold a high-altitude work certificate.

Secondly, the aerial work certificate is a kind of proof that the operator has been trained in safe operation and passed the assessment. This certification ensures that the operator can follow the relevant safety operating procedures when working on the climbing vehicle, effectively reducing the risk of operation. Therefore, from a safety point of view, it is more secure for operators with aerial work permits to work on the climbing vehicle.
However, in practice, there may be cases where a work-at-height certificate may not be required. For example, if the environment in which the vehicle is safe to use, the working height does not exceed 2 meters, and the operator is very familiar with the operation of the climbing vehicle, then in this case, a working at height certificate may not be required. 
In general, whether a high-altitude permit is required for operations on the climbing vehicle needs to be judged according to the specific operating environment and safety requirements. If the working height is more than 2 meters, or there are large safety hazards in the working environment, then the operator needs to hold a high-altitude work certificate. Otherwise, if the working environment is safe and the operator is very familiar with the operation of the climbing vehicle, then a working at height certificate may not be required. But in any case, safety always comes first, and we should always follow the relevant safety operating procedures to ensure the safety of the operation.
