Abstract: A power hoe is provided, which includes an electric motor operating tools for work in the ground and at least one battery intended to power the motor and having a set of functionalities. The power hoe is able to operate in at least two operating modes selected according to at least one information item representative of a level of charge remaining in the battery or batteries. These operating modes include, at least: a normal operating mode, in which all of the functionalities of the equipment are available, including a functionality allowing the motor to be supplied with additional power for a limited period of time; and a downgraded operating mode in which at least the functionality allowing the motor to be supplied with additional power is disabled.

Abstract: A device for determining when a threaded joint for steel tubes having a male element (1) with external threads (3) with a screw limiting stop (5), and a female element (2) with corresponding internal threads (4) and a corresponding screw limiting stop (6) is properly made up is provided. The device comprises a strain gauge (12) and means (10, 11) for applying said gauge on the external surface of the female element (2) such that the gauge can measure superficial deformations of the female element (2) in the longitudinal direction along one of the generatrix of the female element.

Abstract: A process is provided for executing the screwing of a threaded joint for steel tubes, designed especially for the petroleum industry, of the type having a male element (1) with external threading (3) and female element (2) with internal threading (4), as well as at least one pair of screwing limit stops (5, 6). A strain gauge which allows the instantaneous determination of longitudinal deformations of the external surface along a line of the female element (2) is applied to the external surface of the female element (2) at a certain distance from the plane of the screwing limit stop and on the side of said plane which is opposite to the threads (3, 4), and the screwing down of the joint is executed until the indications provided by the strain gauge corresponds to an extension of a predetermined value of the surface of the female element (2) along said line at the level of the gauge.
