A construction equipment comprises a working element and at least one actuation device for operating the working element relative to a support element of the construction equipment. The actuation device includes a carriage guided and movable along an 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.

Construction equipment

Construction equipment includes a framework and at least one electric actuator for moving at least one element of the framework. The actuator includes a ball or roller screw system having a threaded rod and a nut forming a helical connection with the threaded rod. An electric motor drives the rod in rotation around a longitudinal axis, forcing the nut to move axially along the rod. A carriage is axially connected with the nut. An axial guide guides the movement of the carriage. The guide is fixed to the framework. At least one support element connects, directly or indirectly, the threaded rod to framework. The support element is designed so that threaded rod can tilt, to some extent, relative to framework around any axis perpendicular to rod longitudinal axis.

Construction equipment provided with a specific arrangement to allow titling movement within electric actuator

A construction equipment includes an electric actuator including a rod extending along a longitudinal axis, a sliding member movable along the rod, an electric motor for converting electrical power into a movement of the sliding member along the longitudinal axis, a connecting rod including a first end which is articulated on sliding member and a second end which is articulated on a first element of the construction equipment in order to move the first element relative to a second element or inversely and guiding means for guiding the movement of the sliding member the longitudinal axis. The electric motor, the rod and the sliding member are integrated into the second element of the construction equipment.

The invention relates to an engine air filter unit for a vehicle () that is designed to supply filtered air to an internal combustion engine of the vehicle (). The engine air filter unit () comprises a main filter (), a mounting base () to secure the engine air filter unit () on at least one body panel () of the vehicle, a pre-separator fluidically connected to the main filter. The main filter () is arranged on a side of the mounting base () and the pre-separator () is arranged on the opposite side of the mounting base (). The pre-separator housing is at least partly formed by the mounting base () and an air duct () extends through the mounting base () to fluidically connect the pre-separator to the filtration chamber.
