Adjustable camera stand - movable along column by means angle of pulley, and lockable by lever with respect to azimuth position and height

摘要

The carrier (2) is moved up and down the column (1). It is connected to a counterweight (9) by a cable (7) and pulley (8). It is locked in the required position by the lever (3) on its outer section (12). The centre section (14) of the carrier rotates in azimuth and is locked by the lever (15). Angular displacement is read from the scale (16). The column is of square section. The carrier may have sliding bushes but preferably has eight roller bearings, two against each face. Ring clamps (10) allow camera feet (11) to be fastened to the transverse arm (5).
