Method to make to rotate a drum of a concrete mixer comprising a vehicle provided with a movement unit having wheels, to effect the movement of the vehicle, a concrete mixer mounted on the vehicle and comprising a drum, and a device to selectively make the drum rotate. The method provides to feed an electric motor connected to the drum by means of an electric energy generator unit suitable to selectively feed the electric motor.

Truck mixer with device to make the drum of the mixer rotate

Truck mixer comprising a vehicle provided with a heat engine which cooperates with a movement unit having wheels, to effect the movement of the vehicle, a concrete mixer mounted on the vehicle and comprising a drum, and a device to selectively make the drum rotate. The device comprises an electric motor connected to the drum, and an electric energy generator unit suitable to selectively feed the electric motor.

Truck mixer with a device to make the drum of the concrete mixer rotate and corresponding method

Vehicle to project concrete, including a truck provided with a main motor to move the truck using a movement unit, a unit to project the concrete equipped with a pumping device configured to feed the concrete along a pipe, where the vehicle includes a unit to generate and feed electric energy configured to selectively feed one or more of either the movement unit of the truck, the concrete projection unit and the pumping device.

Vehicle to project concrete

A concrete mixer truck comprises a vehicle provided with a heat engine and a concrete mixer having a rotating drum and an auxiliary device provided with a unit for generating electric energy that selectively feeds an electric motor connected to the rotating drum. The electric energy generating unit comprises at least an alternator selectively connectable to the heat engine and to a movement unit of the vehicle by means of a gearbox and a power take-off positioned between the clutch of the vehicle and the gearbox. The alternator is configured to convert mechanical energy into alternate electric energy and vice versa. The electric energy generating unit also comprises at least one accumulator and reversible conversion means of electric energy, connected to the accumulator and to the alternator in order to selectively take continuous electric energy from the former and supply alternate electric energy to the latter, to move the drive wheels of said movement unit, or to convert the alternate electric energy produced by the alternator into continuous electric energy to be transferred to the accumulator.

Concrete mixer with perfected auxiliary device

Truck mixer with safety device, comprising a drum rotatable around an axis of rotation by means of rotation devices, which comprise a first drive member of the electric type suitable to make said drum rotate, during normal use, and a second drive member that functions as a safety device, able to be selectively actuated in a condition of non-usability, even temporary, of said first drive member, and also suitable to make the drum rotate.
