Claims

[Scope of utility model registration request]

A tilting hydraulic response device is installed between the cab of the truck and the vehicle body frame, and tilts the cab up or down around a pivot at the lower front end portion of the cab by its expansion and contraction, and is installed in parallel with the hydraulic response device. A mechanical locking device comprising a column that is displaced together with the device and a locking member that engages with the column and prevents contraction of the hydraulic response device when hydraulic pressure oil is lost in the hood when the hydraulic response device is extended; An electric motor that drives a hydraulic pump that supplies hydraulic oil to the response device; and an electric motor that selectively supplies hydraulic oil from the hydraulic pump to a tilt-up side working chamber and a tilt-down side working chamber of the hydraulic response device. a tilt-up circuit that is connected in parallel between the electric motor and the power source and includes a first normally closed switch that opens when the locking device is actuated; and a second normally closed switch that opens when the cab is in the normal running position. a motor activation circuit comprising a tilt-down circuit including a normally closed switch and a selection switch operated by an operator to connect either the tilt-up circuit or the tilt-down circuit to a power source, and in parallel to the motor energization circuit; It includes an electrical alarm device such as a connected buzzer, and when the locking device is activated, the switching valve communicates the tilt-up operation chamber of the hydraulic response device with the hydraulic pump, and the tilt-up operation chamber of the hydraulic response device communicates with the hydraulic pump, and the A cap tilt device for a truck, characterized in that it is configured to be driven by an electric motor.
