A gripping block includes a rear side with a largest rear side width, a front side with a smallest front side width and an outer surface with a friction generating surface arranged over at least a part of the outer surface, a first side face, and a second side face. The first side face and the second side face are arranged opposite of each other. The rear side abuts against an inner wall in a slot in a holding device. The largest rear side width is smaller than the smallest front side width.

A method for pushing and pulling rod strings through the ground or an underground pipe. A grip assembly is supported on a stationary frame and moveable relative to the stationary frame. The grip assembly has a slip bowl tapering from a large opening to a small opening in a first direction, a plurality of slips, and an actuator. The actuator powers relative axial movement between the slip bowl and the slips. A positioning assembly carries the grip assembly and powers its reciprocating and straight-line movement to urge the grip assembly in either a first or second direction. The grip assembly will work when operated to push or pull the pipe, irrespective of the is direction of the slips.

An apparatus for slip monitor and control includes a body; a plurality of slips; a transmitter for each slip; at least one receiver coupled to the body; and an actuator for each slip configured to move the respective slip vertically relative to the body. A method for slip monitor and control includes obtaining slip positional information for a plurality of slips; determining whether the slip positional information for each of the slips matches criteria; and sending one or more control signals to one or more actuators, each actuator configured to move one of the slips vertically relative to a body. A method for handling a tubular includes actuating a plurality of slips to move vertically relative to a body; engaging the tubular with at least one of the slips; measuring positional data of the plurality of slips; and identifying an offset pipe condition.
