- counterweight is meant both a counterweight in the conventional sense of the term and a balancing mass.
- the installation may include a counterweight having a mass less than that of the cabin, equal to that of the cabin, or greater than that of the cabin.
- the installation may also have no counterweight.
- the linear element of the closed loop may comprise a belt, of relatively flat section, and comprising for example metal cables embedded in a matrix.
- the pulleys of the closed loop can thus be chosen relatively small diameter for more compactness.

- the installation can be devoid of counterweight.
- the linear element may for example comprise a belt, or other.
- the linear element may be unique, that is to say that the closed loop is then made with a single linear element, for example a single belt.
- a linear element can be provided in several parts, possibly of different natures, for example a belt part passing through one of the two pulleys of the closed loop, and a cable part passing through the other of the two pulleys of the loop. closed.
- the drive motor may be part of the closed loop, or not.
- the invention is limited to a particular location of the drive motor, provided that this motor allows to drive in motion the linear element.

- it will be possible to laterally offset the motor for example by using an additional linear element mounted on the motor and on one of the two pulleys.
- the measured value of the parameter representative of the engine torque can for example be derived from a value of current consumed by the drive motor, a power value consumed by this drive motor, and / or other.
- the value received in step (a) can be measured when the car is at a standstill. We can thus improve the accuracy of the estimation to the extent that some factors of the friction type or otherwise, then exert relatively little influence on the engine torque.
