Rolling Water Well Rig With Tilting I-Beam Mast

Getting a water well drilled usually means bringing in heavy machinery, and that is the problem this build takes on. Cypsmen put together a portable rig for water drilling that rolls on its own wheels, with a mast that sits horizontal until it is swung upright where the work happens.



The frame begins as rectangular steel tubing, cut and held with magnetic welding squares, then MIG welded into a rolling base. Fixed axles with pneumatic wheels and a pivoting dual-wheel caster assembly carry it along, and an upright T-shaped handle stands on the base frame. Twin vertical stanchions welded to the frame take a pivot pin for the mast, a heavy steel I-beam. A hydraulic long-ram jack actuates the mast between horizontal and vertical, and outdoors the maker tilted it up using the ram handle.



The sliding carriage plate runs on four grooved steel roller bearings riding the I-beam flanges, secured with bolted hardware. Mounted on it is the drive: a heavy electric motor with an integrated gearbox and output sprocket, with a downward-facing output shaft and flange or gear coupling beneath the gearbox, set up to drive a vertical tool like an auger or drill stem. The motor was moved into place on a hand truck. Lifting duty falls to an electric winch labeled MAR-POL on the base frame, with steel wire rope routed through pulleys, and a yellow wired pendant control raises and lowers the carriage.



What stays open for me is downforce. The working method is to drill one pipe section down, lift the carriage, thread on another section and repeat, and I keep wondering whether the weight of the motor and a stack of pipe gives enough push against hard earth or rocks, and whether the frame holds up against reaction torque. That answer has not surfaced yet.

One thing I keep coming back to is the carriage. With four grooved roller bearings running on the I-beam flanges, how are they arranged to stop the plate twisting under the motor? Are they paired on both flanges top and bottom, or is the bolted hardware doing more of the location work?

The maker has not said how the bearings are arranged. What is known is that the carriage plate carries four grooved steel roller bearings riding along the I-beam flanges and is secured with bolted hardware. Beyond that, how the load is shared between the bearings and the bolts has not been spelled out.
