| 发明名称 | Conveyance cart | ||
| 摘要 | A conveyance cart that can convey a loaded burden, includes: a body frame supported by a wheel; 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; and a controller that is configured to supply an electric current to the electric actuator. The controller stops supply of an electric current to the electric actuator when a continuous driving time of the electric actuator is equal to or longer than a predetermined time. | ||

| 主权项 | 1. A conveyance cart configured to convey a loaded burden, the conveyance cart comprising: a body frame supported by a wheel; 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; and a controller that is configured to supply an electric current to the electric actuator, wherein the controller stops supply of an electric current to the electric actuator when a continuous driving time of the electric actuator is equal to or longer than a predetermined time, and the controller includes an electric current determination part that is configured to determine whether or not an electric current having a range supplied in a normal use continuously flows to the electric actuator for the predetermined time or longer, andan electric current control part that is configured to stop supply of an electric current to the electric actuator based on the determination of the electric current determination part. | ||
