The lifting assembly 10. 110 is provided for lifting oilfield tubular members T onto the floor of a derrick D. The assembly includes a lower base 12 which is positioned at a selected location relative to the derrick, and an upper platform 14 pivotally connected at its rearward end to the base. The upper platform has a substantially planar upper surface with a lateral width sufficient for supporting a plurality of oilfield tubulars T thereon. One or more v-shaped troughs 52, 54 are positioned along the platform each for receiving one of the plurality of oilfield tubular members. A hydraulic ram 16 operates against an inclined slide member 20, 116 for tilting the upper platform 18 relative to the base. A powered ejection unit 34 moves a tubular within the trough with respect to the derrick. A push member 56 substantially encloses the v-shaped trough and pushes the tubular. The method of the invention enhances oilfield operations by reducing delays, and substantially improves worker safety.
