The least expensive way to make a bench height-adjustable, with 8″ (200 mm) of manual travel. No power supply is required, which makes it the practical choice for cleanrooms, wash-down areas and remote workstations with no outlet nearby. The crank folds flat once the height is set so it does not obstruct the working area. Four LA 1420 linear units (1.38″ x 1.38″) on a hand-cranked pump, rated to 992 lbs (450 kg) including the frame. Lifting speed 0.2″ (5 mm) per turn.

For more range, see the 12″ (300 mm) and 15.75″ (400 mm) hand crank systems. If the bench will be adjusted several times a day, a motorized hydraulic system will be less tiring.
A manual hand crank system consisting of:
1 x pump with hand crank, 4 x linear LA 1420 (1.38”x1.38”) with 2x10ft and 2 x 8ft tubing connected to the pump, 4x levelling feet, 1 x drilling template and tubing mounting hardware.
