It is available in a variety of lip lengths up to 1,000 mm and dynamic capacities from 6-8 tonnes, for accurate and efficient loading and unloading. The X-Series is supplied with an auto-park function as standard; with a push of a button, the leveller is brought back to its start position.

Wide Choice of Lip Lengths: The Stertil telescopic lip X-Series levellers offer numerous possibilities and can be customised for your loading and unloading dock requirements. The length of the platform will primarily be determined by the height difference between the warehouse floor and the expected range of vehicle loadbeds. In order to guarantee smoother loading and unloading with less physical strain, Stertil Dock Products base its sizes on a lower maximum incline than is stipulated by the EN 1398 Directive.

Ideal for end loads: The Stertil Dock Products' Telescopic Dock Leveller is a highly practical and reliable solution. The telescopic lip is fully controllable at variable lengths of up to 1,000 mm. This makes the dock leveller ideal for efficient loading and unloading end loads at the back of the truck. The long chamfers and the lip angle ensure a smooth transition from the dock leveller to the vehicle floor in every situation. The various installation methods, wide range of sizes and load capacities of 6 or 8 tonnes make the X-Series telescopic dock leveller very versatile.

Optimum safety: In case of premature vehicle departure whereby the forklift truck is still on the X-Series telescopic 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 console can also be operated manuallyDuring 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 X-Series Stertil Dock Products 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.
