| General |
These heavy duty instrument stands provide
exceptional rigid support for Optical Alignment and other instruments. They are easily
positioned by rolling on retractable rubber-covered casters. A quick release mechanism
places these stands on three adjusting bolts with swivel pad shoes. Adjustable bolts
permit leveling of stand. The height of the center column is adjusted by turning the
capstan wheel which operates the fine adjustment rack and pinion.The Low Instrument Stand
has a height adjustment range from 28” to 44”. The High Instrument Stand has a
height adjustment range from 38" to 74" between floor and instrument base
interface. A clamp lock and safety ratchet pawl holds the column to any desired height. A
U.S. standard 3 1/2” x 8” thread is machined in the head for instrument
attachment. the column is hollow to permit downward sighting, with a clear 2.0”
diameter aperture. These stands are provided with rubber shock bumpers for instrument
protection if elevation clamp is released under load. A shock-resistant plastic thread cap
is provided. |
| Bases |
Bases are designed for strength and stability. Three casters with
rubber tires are used for mobility and can be retracted into the base. In use, the stand
rests on three adjusting screws with lock nuts. This permits leveling the stand on uneven
surfaces. Main tubes are seamless steel tubing with a clamping collar on the upper end. |
| Columns |
The base and elevation columns are constructed
of heavy seamless steel tubing precision machined. The base column is welded to the base
and is also supported by struts made of heavy wall steel tubing welded to the column to
limit vibration and provide for extreme rigidity during use. |
| Gear Housing |
The gear head housing is made of cast iron and contains the pinion elevation
assembly, clamping collar, safety ratchet as well as an adjustable tensioning mechanism. |
