Abstract: A hoisting apparatus mounted on a vehicle and used to raise oil tubing from within an oil well casing or the like having a lower telescoping boom element that includes a lower secured member and a lower extending member oriented to extend in one direction, and an upper telescoping boom element that includes an upper secured member mounted on the lower extending member with an upper extending member oriented to extend in a direction parallel to but opposite from the one direction. A pulley allows a lifting cable to depend from the lifting end and a lifting cable extends from the extended free end of the upper extending member to the first pulley so that the lower extending member can be extended to position the lifting cable and the upper extending member can be extended to raise the lifting cable.
