1. A construction equipment, comprising a working element, a dipper or a boom, and at least one actuation device for operating the working element relative to a support element of the construction equipment, the at least one actuation device including:
a carriage which is guided and movable along a first axis,
an electromechanical actuator which, when activated, converts electrical power into a first force moving the carriage along the first axis, and
a hydraulic actuator, which connects the carriage and a first element that is either the working element or the support element so as to move the working element relative to the support element with at least partly the first force when the electromechanical actuator is activated, and which, when activated, converts hydraulic power into a second force moving the first element and the carriage relative to each other.
