Workpiece support apparatus

A workpiece support apparatus, comprising:

• an elongate channel-form primary body having a first end, a second end, a longitudinal axis, a first sidewall and a second sidewall;
• tracks extending longitudinally along each of the first sidewall and the second sidewall of the primary body;
• several height adjustable primary support columns extending vertically from the primary body, each of the primary support columns having a base with rollers that engage the tracks of the primary body for axial movement along the primary body whereby the primary support columns are selectively positioned;
• elongate channel-form arms extending radially from and being pivotally secured to each of the first sidewall and the second sidewall of the primary body, each of the arms pivoting about a substantially vertical axis for angular adjustment on a substantially horizontal plane, each of the arms having a first end, a second end, a longitudinal axis, a first sidewall and a second sidewall;
• tracks extending longitudinally along the first sidewall and the second sidewall of each of the arms;
• height adjustable secondary support columns extending vertically from each arm, each of the secondary support columns having a base with rollers that engage the tracks of the arms for axial movement along the arms whereby the secondary support columns are selectively positioned.

• several height adjustable primary support columns extending vertically from the primary body, each of the primary support columns having a base with adjustable rollers that engage the tracks of the primary body for axial movement along the primary body whereby the primary support columns are selectively positioned;
• laser alignment targets being provided on each of the primary support columns for aligning the primary support columns in a straight and level orientation along the longitudinal axis of the primary body;
• elongate channel-form arms extending radially from and being pivotally secured at pivotal connections to each of the first sidewall and the second sidewall of the primary body, each of the arms pivoting about a substantially vertical axis for angular adjustment on a substantially horizontal plane, each of the arms having a first end, a second end, a longitudinal axis, a first sidewall and a second sidewall, each of the arms having underlying rollers, the pivotal connections having several apertures, the arms being locked in a selected angular position by inserting a locking pin into one of the several apertures;
• tracks extending longitudinally along the first sidewall and the second sidewall of each of the arms;
• height adjustable secondary support columns extending vertically from each arm, each of the secondary support columns having a base with adjustable rollers that engage the tracks of the arms for axial movement along the arms whereby the secondary support columns are selectively positioned;
• each of the primary support columns and each of the secondary support columns having a screw levelling adjustment;
• each of the primary support columns and each of the secondary support columns having a top mounting adaptor adapted to receive a workpiece engaging member;
• each of the primary support columns and each of the secondary support columns being fluid activated telescopically extendible cylinders supplied with fluid through fluid lines, the fluid lines extend from each of the primary support columns to a rotary fluid manifold, upon rotation of the rotary fluid manifold in a first direction fluid lines are wound onto the rotary fluid manifold, upon rotation of the rotary fluid manifold in a second direction fluid lines are fed from the rotary fluid manifold, a plurality of direction altering rollers being used to route the fluid lines along the primary body.
