FIELD: electricity.
SUBSTANCE: invention is referred to mobile electric mechanical equipment with a supply cable coupled to a power supply source. The invention suggests a delivery cart (10) intended for the transportation of material in underground workings (versions), as well as a device intended to diminish the damage of the electric transportation vehicle supplied by the supply cable (22) that contains an electric sensor (54, 56) used to determine the position of the mobile equipment in regard to a source of danger and an electric controller interacting with the electric sensor and actuating motor in order to change the operation mode of the electric transportation vehicle in order to diminish the risk of an unfavourable impact on the supply cable when the electric transportation vehicle is close to the source of danger.
EFFECT: invention ensures the reliable indication of the delivery cart position in regard to a certain known position.
