MANITOU ITALIA S.R.L.

An operating machine that includes one or more mobile apparatuses, each operable by one or more respective actuators, a control element operable by an operator, a control unit configured to control the actuators based on the operation of the control element, and one or more operating sensors to detect one or more operating parameters based on operating conditions of the machine. The control unit is configured to control the actuators on the basis of operating relations between an input signal received from the control unit following the actuation of the control element and a speed of an actuated apparatus, which are variable as a function of the operating parameters detected by the sensors.

An operator unit for an operator vehicle that includes at least one actuator, which can be associated with two or more tools or equipment which are alternative to each other, a control device, which is movable and can be positioned in an operating space, and a control module connected to the control device and to the actuator and designed to send to the actuator a control signal whose level is a function of a position adopted by the control device inside said operating space. The control module is programmed with at least two control functions, each of which relates a position adopted by the control device inside said operating space with a level of the control signal. The control module is also programmed with a control algorithm configured for receiving an identification signal which identifies a tool associated with the actuator.

An operating machine provided with an electrical system, a plurality of user devices powered by the electrical system, including an electric motor set up to supply the power required by one or more other user devices, an electrical charge storage device connected or connectable to the system and arranged to power the user devices of the machine, a control element which can be operated by an operator to control the operation of one or more user devices and an electronic processing unit comprising a power management module configured to adjust a power delivered to the user devices as a function of at least one safety threshold of a power which can be delivered by the storage device. A generator unit is connected to the electrical system for powering the storage device.

A telescopic cylinder that includes a first cylinder having a first piston slidable in a jacket which has an extension chamber and a re-entry chamber, separated from each other by a head of the first piston and a second cylinder having a second piston slidable in a sealed fashion in a second jacket which has an extension chamber and a re-entry chamber, separated from each other by a head of the second piston. The jacket of the first piston is integral with the second piston. The telescopic cylinder further has an outer conduit, connected to the re-entry chamber of the second cylinder for allowing the supply and discharge of oil. The outer conduit has a first body having a first slider and a second body having a second slider, wherein the first slider has a first inner channel and the second slider has a second inner channel.

A telescopic cylinder that includes a first cylinder having a first piston slidable in a sealed fashion in a jacket which has an extension chamber and a re-entry chamber, separated from each other by a head of the first piston. A second cylinder of the cylinder has a second piston slidable in a sealed fashion in a jacket which includes an extension chamber and a re-entry chamber, separated from each other by a head of the second piston. The jacket of the first piston is integral with the second piston and a conduit for connection to the extension chamber of the second cylinder is made at least partly through the first piston and the second piston. A compensating device is provided with a control module configured for adjusting a flow rate of operating fluid to be fed to or discharged from the extension chamber.

A device for controlling movement of a load. The device includes a first conduit, designed to be connected to a first chamber of a hydraulic actuator, a second conduit designed to be connected to a second chamber of the hydraulic actuator, a first balancing valve, positioned along the first conduit, which is normally closed and is actuated towards an open position by the pressure present in the second conduit, a second balancing valve, positioned along the second conduit, which is normally closed and is controlled towards an open position by the pressure present in the first conduit, and a third balancing valve, positioned along the first conduit, which is normally closed and is actuated towards an open position by the pressure present in the second conduit.

Described is a telehandler equipped with a carriage movable on wheels and a driver's cab ( 1 ), located above the carriage, which comprises an access door ( 10 ) equipped with two side jambs ( 11, 12 ), to each of which is fixed a continuous handle ( 2, 3 ) the length of which is greater than half the length of the respective jamb ( 11, 12 ).

A self-propelled operating machine includes a traction motor, a hydraulics system motor, a battery, and a processing unit configured to control operation of the traction motor and the hydraulics system motor. The processing unit is further configured to determine a state of charge of the battery, determine a maximum battery power that can be delivered by the battery based on the state of charge, determine a maximum traction power to be delivered to the traction motor based on the maximum battery power, determine a maximum hydraulic system power to be delivered to the hydraulics system motor based on the maximum battery power, limit instantaneous power delivered to the traction motor based on the maximum traction power, and limit instantaneous power delivered to the hydraulics system motor based on the maximum hydraulic system power.

Described is an attachment device ( 1 ) for telehandlers ( 100 ) designed to be connected to an operating arm ( 101 ) and comprising a front frame ( 12 ) designed for removably attaching an accessory ( 102 ) for engaging a load, such as a fork, a side shift carriage, a winch or a loading platform. The frame comprises two lateral sides ( 121 ) and two crosspieces ( 122 ), of which one upper and one lower, which join the side elements ( 121 ) to each other. One or more crosspieces ( 122 ) have an oblique inner side ( 120 ) relative to a horizontal plane.
