Abstract
A work support and method of clamping a translatable component of a hydraulic work support system. The work support may include a rigid, hollow slotted collet, a sleeve, and the translatable component, such as a plunger or rod. Hydraulic fluid may be pumped into an inlet of the hydraulic work support system to hydraulically actuate the translatable component outward from a first retracted position to a second extended position. The hydraulic fluid may further be pumped to the sleeve at a sufficient pressure that the sleeve presses against the collet. The collet responds thereto by flexing into contact with the translatable component, thus holding the translatable component in the second extended position. The slots in the collet allow for flexure even when using a thicker material with stronger column strength.
