This 1985 Calweld 200CH is a vertical drill — also referred to as a foundation drilling rig or rotary drill rig — designed for deep foundation work including drilled shafts, caissons, and large-diameter bored piles. Calweld is a well-established American manufacturer with a long history of building crane-mounted and truck-mounted drilling equipment for the heavy civil construction and deep foundation industries.
This particular machine is configured as a crane-mount rig, meaning it is designed to be suspended from and operated in conjunction with a crane, a common setup for deep foundation applications requiring precise positioning and significant crowd force. Power is provided by twin Detroit diesel engines, giving the rig a robust, redundant power source well suited to demanding drilling conditions. The rig is rated for a digging depth in excess of 150 feet, making it capable of reaching the deep bearing strata required for large structures, bridges, and other heavy civil projects.
The machine is equipped with large-diameter tooling, indicating it is set up for producing wide-bore holes consistent with drilled shaft and caisson work rather than smaller exploratory or geotechnical borings. According to the seller, the rig has accumulated very low hours since new and is described as being in excellent condition, which is notable given its 1985 manufacture date. The machine is currently located in California, USA.
