A workpiece support system has a driven, circulating traction device, a stationary base frame, and at least one workpiece support that has a load carrier and a traction carriage. The traction carriage has a clamping device with upper and lower clamping elements between which the traction means is arranged and with which the traction carriage is clamped by a clamping action onto the traction device. The traction carriage has a spring element that exerts a spring force on at least one of the upper and lower clamping elements for effecting the clamping action. The workpiece support has an actuating element arranged in a leading area in a travel direction of the workpiece support. The actuating element reduces a camping force of the clamping action when the workpiece support bumps into a leading workpiece support in the travel direction. The traction device is guided about two pulleys.
