Described is a lift truck comprising an energy storage unit (4), consisting of a plurality of battery modules or packs (23), for powering a drive unit (2) and one or more auxiliary user devices (3);an electric circuit (5) is designed for distributing energy from the energy storage unit (4) to the drive unit (2) and to the auxiliary user devices (3);a single control and management system (6) of the lift truck (1) and of the passage of current from the energy storage unit (4) to the drive unit (2) and to the user devices (3) through the electric circuit (5);the control and management system (6) comprises at least one module (7) for managing the energy storage unit (4), a solid state switch (9) and a single contactor (12), having a relative control card (11), for controlling the opening or closing of the passage of current towards the drive unit (2) and the auxiliary user devices (3);the management module (7) of the energy storage unit (4) is configured to send a control signal (8) to the solid state switch (9) in response to which it switches a branch (10) of the electric circuit (5), for opening or closing, for powering the control card (11) of the contactor (12).

Described is a with a door or window frame comprising a system (1) for locking a handle (2) which can be associated with it that comprises a fixed frame (4) and a mobile frame (5) configured to pass from a closed configuration to an open configuration in relation to the relative position between the mobile frame (5) with respect to the fixed frame (4); the handle (2) which can be associated with the door or window frame (3) which comprises a pin (6) for controlling operating means (7) for forming the closed or open configuration of the mobile frame (5) with respect to the fixed frame (4); the locking system (1) comprises a seat (8) in which the control pin (6) of the handle (2) can be inserted and the control pin (6) can be rotated in the seat (8); the seat (8) has a recess (9) configured for inserting a tab (10) of the control pin (6) and a guide element (12) configured for guiding, in use, the tab (10) of the control pin (6) starting from the recess (9) up to an end of stroke position (11); the guide element (12) defines a feed path of the tab (10) during its rotation from the recess (9) to the end of stroke (11), and vice versa.

Described is an operating system for a door or window (1) comprising operating means (7) configured for moving the door or window (1) from the closed configuration to the open configuration, and vice versa, wherein the open configuration comprises a side hung or tilt and turn opening; retaining means (108) can be engaged with a pin (10) for controlling the opening and closing of the articulated arms (12) for keeping it in a non-operating condition of the electric actuator (6) and in a rotated position of the handle (5), preferably by 90°, corresponding to a tilt and turn opening configuration of the door or window (1) and for disengaging it in an operating condition of the electric actuator (6) for performing a tilt and turn opening of the door or window (1).
