With dynamic capacities of 6, 8, 10.5 and 12 tons is the S-Series dock leveller extremely versatile. The dock leveller is available in many different sizes and is an excellent choice for almost every dock situation.


Lifetime warranty on the Open Lip Hinge

The unique hinged lip has big advantages, thanks to the open construction, accumulation of dirt is impossible. Furthermore, the construction is much stronger than a traditional piano hinge, therefore Stertil provides a lifetime warranty on the open lip hinge. The levellers which are wider than 2,000 mm are equipped with a tapered lip for badly centered trucks.


Optimum safety

In case of premature vehicle departure whereby the forklift truck is still on the dock leveller, the automatic panic-stop activates. The leveller in most cases remains in operation even after a panic-stop situation. The emergency stop button on the control box can also be operated manually


During maintenance, the dock leveller is held safely in position by means of a special maintenance strut. When the leveller is in parked position, it is automatically supported by two cross-traffic safety legs.


Interlock Operation System

The dock leveller can be positioned perfectly using the three control buttons, and returned to the parked position using the standard auto park function.


There are several advanced control options which provide additional functions such as door control, shelter control, automated interlock to prevent operation when the dock door is not fully open, and automatic door closure locking until the leveller has been parked correctly.
