Abstract: A mat washer includes: a body adapted for highway transport; a loading platform adapted to receive a stacked pair of mats from, for example, a forklift, and adapted to pivot the pair of mats to an upright position; a splitter adapted to receive the mats from the loading platform and to separate the mats from one another; a transporter adapted to transport each of the mats longitudinally relative to the body from the splitter; a uniter adapted to receive the mats from the transporter and urge them together; an unloading platform adapted to receive the pair of mats from the uniter and pivot them downwardly for retrieval by, for example, the forklift; and a washing facility disposed between the loading and the unloading platform and adapted to wash the mats.

Abstract: A wellbore tubular handling system for applying a downforce to wellbore tubulars using a service rig. A downforce system includes a first frame assembly coupled to a slip assembly for engaging wellbore tubulars, a base member connected to the first frame assembly, and an actuator adapted to extend and/or retract the first frame assembly between a first position and a second position, wherein the second position is laterally displaced from the first position along a path formed by extension of the actuator, and wherein the base member is connected to the mast of the service rig. A method of applying a downforce to a wellbore tubular using a downforce system for a service rig.
