Drive train apparatus

In a materials handling device having an element driven by a rotating shaft from a first position to a second position, the improvement comprising a first motor operatively coupled to the rotating shaft, a second motor operatively coupled to the rotating shaft, said first motor having means to drive said rotating shaft substantially faster than said second motor, means to sense when the element reaches a preselected distance from said second position, means to sense when the element reaches the second position, a brake mounted to the rotating shaft, and means to control said motors and brake so that the first motor drives a rotating shaft until the element reaches the preselected distance, the second motor drives a rotating shaft from the preselected distance to the second position, and the brake stops the rotating shaft when the element reaches the preselected distance, wherein an oil lubricated gear box having a level of oil and having bearings is driven by said rotating shaft and further comprising an automatic bearing oiler for said gear box including a cylinder, a supply line tapped into the gear box below the oil level and extending to said cylinder, a lube line extending from the cylinder to at least one bearing, and means to repeatedly operate said cylinder to deliver oil to the bearing.
