A shovel 100 according to an embodiment of the present disclosure comprises a lower traveling body 1, an upper turning body 3 mounted on the lower traveling body 1 so as to be capable of turning, a hydraulic actuator that drives a part to be driven including the lower traveling body 1 and the upper turning body 3, a main pump 14 that supplies hydraulic oil to the hydraulic actuator, a pump motor 12 that drives the main pump 14, and a power storage device 19 that supplies electric power to the pump motor 12. In addition, the shovel 100 causes the hydraulic actuator to transition to an inoperable state if a charging cable is connected to a charging port 72 while the shovel 100 is operating. In addition, as long as the charging cable is connected to the charging port 72, the shovel 100 does not activate the pump motor 12 even when an input to activate the pump motor 12 is received from a user.
This asphalt finisher comprises: a tractor; a hopper installed on the front side of the tractor; a conveyor for conveying paving material in the hopper to the rear side of the tractor; a screw for spreading, in the vehicle width direction, the paving material conveyed by the conveyor and scattered on a road surface; and a screed device for evenly spreading, behind the screw, the pavement material spread by the screw. The operation of a transport vehicle is synchronized so as to correspond to the operation of the asphalt finisher.
