Operational Features

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.

Wide Choice of Lip Lengths

The Stertil Dock Products telescopic lip X-Series levellers offer numerous possibilities and can be customised for your loading ba dock situation. 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

Standard X-Series Leveller

The Stertil Dock Products' Telescopic X-Series Dock Leveller is a highly practical and premium solution. It has fully controllable variable lengths of up to 1,000 mm. The long chamfers and the lip angle ensure a smooth transition from the warehouse floor to the floor of the vehicle.

Stepped Frame

Combine the X-Series telescopic leveller with a stepped frame base frame. This makes it possible to quickly dock vehicles without the need of opening doors. Furthermore, it is the solution for a complete Cool Chain solution.

Flexible width

The X-Series dock leveller can be equipped with independent side sections on both sides of the telescopic lip. This makes it possible to dock a variety of vehicles of different width on the same loading bay.

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 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 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.

Installation and Maintenance

The X-Series Telescopic Lip dock levellers can be installed with a base-supported frame (XP) in a closed pit, or a suspended frame (XF) in an open pit. Both types of installation are simple to carry out. Stertil Product Managers and Engineers can provide all of the necessary information for construction and installation including drawings.

The telescopic levellers guarantees smooth loading and unloading, minimising the risk of damage to goods and to loading trucks. This considerably increases their operating life and cuts down on maintenance. The leveller itself offers superb performance due to the high quality materials from which it is manufactured, thus low maintenance costs and high return on investment.
