Hydraulic turner designed to rotate precast concrete box culverts through 90° from their casting position to their installation orientation. It handles units from 1 to 4.27 m in both length and width and from 1 to 2.44 m in height. The maximum load is 25 tonnes, subject to the position of the unit’s centre of gravity relative to the pivot axis.
The L-shaped tilting frame has timber pads at the points of contact with the concrete and pivots on a fixed base anchored to the floor. An 11 kW hydraulic power unit drives two double-acting cylinders, each with a stroke of 1,900 mm. The operator controls the turn and return from a control panel. Limit switches stop the movement at 0° and 90°.
