Abstract: A battery holder for containing an electric storage battery is transported by a lift unit on a mobile vehicle. The lift unit is pivotally mounted at a rearward end portion of the vehicle to move into surrounding relation with the battery holder positioned on the ground. The lift unit is pivoted upwardly to raise the battery holder to a preselected elevation within the minimal lateral and overhead clearance available in an underground mine. The lift unit includes a pair of lifting forks extending in spaced parallel relation from the vehicle within the lateral dimensions of the vehicle. The lifting forks have a configuration adapted to permit downward movement of the forks into engagement with the ground to pick up a battery holder positioned on the ground. The lifting forks extend laterally of the battery holder and engage the holder for vertical movement to an elevated position that does not exceed the uppermost position for transportation of the battery in areas of minimal overhead clearance.
