Abstract
A rod elevator including a first latching mechanism and a second latching mechanism connected to one another in a spaced apart relationship for connecting a pair of rods to one another in an axially aligned relationship. Each of the latching mechanisms has a rod receiving space axially aligned with a rod receiving space of the other latching mechanism.
Claims1
A method of pulling a sucker rod string from a well bore, the sucker rod string suspended from a horsehead of a pump jack, the sucker rod string having a polished rod extending through a stuffing box and a pony rod extending from an upper end of the polished rod, the pony rod having an area of reduced diameter, the method comprising:
- obtaining a rod elevator comprising:
- a first latching mechanism having a first body and a first pair of latch members, the first body provided with a first notch on one side thereof, the first notch defining a first rod receiving space sized to receive the latching section of one of the first rod and the second rod, the first pair of latch members pivotally attached to the first body and extending from the first body into the first rod receiving space;
- and
- a second latching mechanism having a second body and a second pair of latch members, the second body provided with a second notch on one side thereof, the second notch defining a second rod receiving space sized to receive latching section of one of the first rod and the second rod, the second pair of latch members pivotally attached to the second body and extending from the second body into the second rod receiving space;
- wherein the first latching mechanism is connected to the second latching mechanism in a spaced apart relationship with the first rod receiving space of the first latching mechanism substantially aligned with the second rod receiving space of the second latching mechanism;
- interconnecting a rod to a traveling block of a hoist system, the rod having an area of reduced diameter on at least a lower end thereof;
- connecting the first latching mechanism to the lower end of the rod by inserting the area of reduced diameter of the rod into the first rod receiving space of the first latching mechanism;
- connecting the second latching mechanism to the pony rod by inserting the area of reduced diameter of the pony rod into the rod receiving space of the second latching mechanism so that the rod and the pony rod are in a spaced apart, axially aligned relationship,
- wherein the rod has a length such that the traveling block is maintained above the horsehead in a non-contact relationship thereto.
