    摘要： Disclosed is an electric assist cart that can travel by applying an assisting force in addition to a driving force applied by an operator. A controller operates an electric motor to apply a determined assisting force to a drive wheel and lifts or lowers a deck lift portion in response to an instruction for lifting or lowering a deck. When a handling detection part detects an instruction for braking the brake, the brake is braked, and an operation of the electric motor is inhibited regardless of a detection result of the torque detection part.

    摘要： An electric assist cart includes: a body frame; a drive wheel; a control handle by which a user can input a driving force to the body frame; a torque sensor that detects a driving torque input to the body frame from the control handle; a controller that computes an assisting force based on the driving torque; and an electric motor that applies the assisting force to the drive wheel. The controller includes an electric current determination part that determines whether or not an electric current having a magnitude equal to or larger than a first setting value continuously flows for a first setting time, and an electric current control part that reduces a maximum value of the electric current that can be supplied to the electric motor to be smaller than the first setting value based on the determination of the electric current determination part.

    摘要： A conveyance cart includes: a body frame; a deck provided liftably against the body frame to load a burden; an electric actuator electrically driven to expand or contract to lift or lower the deck; a current detection element that detects an electric current value supplied to the electric actuator; and a PWM control element that drives the electric actuator in a pulse width modulation (PWM) control manner. The PWM control element increases an on-duty ratio input to the electric actuator if the electric current value detected by the current detection element exceeds a setting value when the deck is lifted.
