Type DLE-NG 60kN

Docklevellers are used in order to bridge the difference in height and distance between the loading bay and the vehicle floor as efficient as possible. The dockleveller ensures an optimal connection between the lip or sliding and the vehicle bed. During loading and unloading the dockleveller will automatically follow each up and down (suspension) movement and due to the lateral flexibility the dockleveller will follow the ‘tilting’ movements of the vehicle as well.

The length of the dockleveller is determined by the maximum acceptable gradient which is governed by the internal transport and type of load. With a greater difference in levels between the vehicle bed and the building floor the dockleveller must be increased in length to reduce the gradient. For more information see Projectplanning.

You can find the available dimensions of the DLE-NG docklevellers in our webshop.

Self supporting sub frame

The DLE docklevellers come standard with a self-supporting sub frame suitable for an open pit with a tail lift opening. No extra horizontal steel construction is required in front of the pit underneath the front beam of the dock leveller. An economic none self-supporting sub frame is optional available for all closed pits.

Please, find below a short description of all the possible pit constructions.

PiT SYSTEM 010

Self-supporting sub frame integrated into the dockleveller

Pit system 010 is a fully “open” construction in which the dockleveller hangs in the pit box (the so called letterbox opening starts immediately beneath the leveller). During production the frame (angular lines) is attached onto the leveller, subsequently the leveller and frame are suspended in a prepared pit box.

The dock leveller is installed in concrete recess by welding on to the existing reinforced concrete pins, which is then back filled with concrete.

PiT SYSTEM 020

Pit system with a concrete intermediate floor

Pit system 020 is provided with a concrete intermediate floor. The leveller rests on the intermediate floor (which does - in standard situations – not support any force). For this pit system, the frame (angular lines) is positioned on location, after which the leveller is welded to it at a later stage. This type of construction does not allow an approach of the dockleveller from the bottom side

A contractor makes the pit and supplies and fixes the pit edge angles and steel plate.

Advantages:

• Dockleveller comes in low transport height to ensure substantial savings (around 50%) in transport costs can be achieved.
• Extremely quick assembly.
• After installation of the dockleveller immediately available for use.

PiT SYSTEM 030

Pit system with concrete console

Pit system 030 provides the rear side of the leveller with a raised edge, on which the rear hinge rests on the rear console. The forces at the hinged side are divided is this manner. For this pit system, the frame (angular lines) is positioned on location, after which the leveller is welded to it at a later stage.

A contractor makes the pit and supplies and fixes the pit edge angles and steel plate.

Advantages:

• Dockleveller comes in low transport height to ensure substantial savings (around 50%) in transport costs can be achieved.
• Extremely quick assembly.
• After installation of the dockleveller immediately available for use

PiT SYSTEM 040

Pit box model with lost shuttering

Pit system 040 is fastened to the dockleveller during production and encloses the complete leveller (cladding on all sides). Subsequently the dockleveller is placed onto a temporarily shuttering, after which the pit box is welded to the reinforcement of the concrete. Next, concrete is poured around the leveller and the shuttering is removed. This work has to be carried out by a contractor.

Pit system 040 is only possible for dockleveller with a maximum length of 3 meters.

Advantages:

• Short installation time / low costs

PiT SYSTEM 059

Pit system especially for dockhouse

Pit system 059 is only used in combination with a dockhouse.
The frame in which the dockleveller later will be welded/bolted consists mainly of the assembled dockhouse (side platforms plus HEA beam with adjustable feet) and a pit edge angle at the back. The dock house and the back of the frame (pit edge angle) are mounted on site. A contractor makes the provisions such as supply and fixing of the pit edge angles.

PiT SYSTEM 060

Self-supporting sub frame integrated into the dockleveller

Pit system 060 is a fully “open” construction in which the dockleveller hangs in the pit box (the tail lift opening starts immediately beneath the dockleveller). The frame is built from an angle of 80x80x8. The angles are reversed welded when you compare this frame to pit system 010. The bracket for the front beam is welded on a solid 6 mm plate. The fixed toe guard is built from a 4 mm plate. On the rear frame, angles of 90x60x6 are welded to support the dockleveller during transport. The width between the side frames is B+20 mm (for example 2020 mm).

Advantages:

• Pour of concrete is not needed 
• Short installation time
• After installation of the dockleveller immediately available for use

PiT SYSTEM 070

Self-supporting sub frame integrated into the dockleveller, suitable for installation with pre-fabricated concrete elements.

Pit system 070 is based on pit system 060. This type (070) is extended with anchors all around the frame. The front side of the frame will be supported by the pre-fabricated concrete elements. To level the frame, two adjusting screws are placed on the rear frame.

Advantages:

• Short installation time / low costs.

PiT SYSTEM 075

Self-supporting sub frame integrated into the dockleveller, suitable for installation with pre-fabricated concrete elements.

Pit system 075 is almost similar to 070 with the major difference that this frame has two adjustment screws on each side to level..

Advantages:

• Short installation time / low costs

pit system 080

Self-supporting sub frame integrated into the dockleveller with adjustable screws, suitable for installation with pre-fabricated concrete elements. 

Pit system 080 is functionally equivalent to pit system 075. However, the frames have been constructed in different ways and with different materials. The side frames of pit system 080 are built in a curved corner of 250x90x6 instead of 80x80x8. The rear frame is constructed in a corner of 80x80x8 and with a bent corner of 170x90x6. The width between the side frames + B is 30mm (for example, 2030 mm).

Advantages:
• Very quick installation and low construction costs.

controlbox typE ACB015

With a 4-switch operation, the movement of the platform and telescopic lip can be individually controlled and they can therefore be accurately moved to the required position. The operation is very simple. By keeping the ‘raise push button’ pressed, the platform moves up from the rest position until it reaches the correct loading height. By means of the ‘lip out push button’, the lip can subsequently slide onto the truck floor until the desired support is realised. When the button is released, the platform and lip will descend automatically to the level of the vehicle bed.
After the loading and unloading process has been completed, by continuously pressing the ‘R-button’ the dock leveller can be returned to the rest position.

In addition, the operation of different dock equipment products, for example the dockleveller and the inflatable dockshelter, can be combined in one controlbox. The ACB015 controlbox works by sequence control. The modular concept of the ACB015 controlbox is easily expanded with several options to increase the safety on and around the loading bay. By means of special programming of the controlbox traffic lights, wheelchocks, docklights, photo sensor etc. can be coupled.

The protection class is IP 65 ACB015.

controlbox ACB015 + OPTIon door/leveller security

When using this safeguard the dockleveller operation is released at the time the sectional door has reached a certain opening. When manually operated doors are used the release is generally provided by a photoelectric sensor. As soon as the safeguard is activated the dockleveller will maintain this setting. The latter is of significant importance since the sectional door will be closed in the meantime and the loading and unloading process will be continued / completed at a later stage. Should a manually operated door be used, a photoelectric sensor can be ordered for this safeguard. By choosing this option the controlbox will be specially prepared for this function and a photo sensor will be included. The program can be activated upon installation.

Paint Black RAL 9005

The standard finish of the dockleveller is painted in the colour RAL 9005 (black).

PRIMER

other RAL colour

THERMo galvanized finish

Thermo galvanising is an effective treatment to ensure a durable anti-corrosion protection. Especially in the food industry (meat and fish processing industry) the application of a hot dip galvanized dockleveller is preferred. The life span of a zinc coating can vary between 10 to 50 years, all depending on the atmosphere to which the galvanised steel is exposed. After the preparation of the steel for galvanisation (e.g. degreasing, rinsing, drying, etc.) it is immersed in a zinc bath, filled with liquid zinc at a temperature between 445°C and 465°C.

After the galvanizing process, the dockleveller can still optionally be painted in the standard colour black RAL 9005. In order to let the paint bond to the zinc layer an additional layer of primer is required.

Insulation – AIR SEALS (between pit/leveller)

Between the edge of the pit box and the dockleveller top platform a narrow opening of approx. 15 mm exists. This opening allows hot or cold external air to rise, which brings draught. To minimise these effects the dockleveller can, on three sides, be provided with air seals. These rubber seals have a thickness of 1 mm and a sealing height of 5 cm; these seal the opening entirely flexible. Mainly with regard to conditioned areas (heated / cooled) the application of air seals is advised:  prevention of draught could result in energy savings and a better working climate.

Insulation – underneath the platform

The steel top platform in itself has a low isolation value. Mainly with regard to conditioned areas (heated / cooled) a significant loss of heated or cooled air could be lost via the steel top platform of the dock leveller. Apart from the use of air seals it is therefore also possible to provide the lower side of the top platform with isolation. The area between the cross beams and the top platform will be completely filled with an isolation layer, which will result in energy savings and an improved working climate.

telescopic lip 500MM

The dockleveller Type DLE-NG comes standard with a straight telescopic lip (slide) of 500mm made of steel 12/14.

telescopic lip 1000MM

The dockleveller can be provided with an extended sliding lip of 1000mm. In this way the range of the dockleveller is increased. This option is available for dockleveller Type DLE-NG (length > 2,5 meters) and offers advantages when an isolated dockleveller is used (the additional space in front of the door is bridged) or when thick buffers are used.

tapered lip on both sides (100X100MM HXB)

The telescopic lip of the dockleveller can be provided with tapered sides. This means that the front side of the slide is narrower. This increases the range of the dockleveller in relation to the width; even smaller vehicles can be loaded and / or unloaded in this manner. 

The degree in which the slide is made narrower depends on the length of the gradient. For a dockleveller DLE-NG the length of the gradients is 100 mm, resulting in a narrowing of 100 mm. In total the front side of the lip is therefore 2 x 100 mm = 200 mm narrower.

flexible side-lips on both sides

Depending on the type of dockleveller model it is possible to provide telescopic side slips. By sliding in the side slips, the possibility is enabled for smaller vehicles to load and / or unload with the dockleveller. The side-lips follow the movement of the slide until an obstacle is within the range of the side-lip. At that time only the slide will extend. When returning to the rest position the side-slips once again follow the movement of the slide.
                                                                                        

When side-slips are applied the slide can be narrowed by : 2 x 150 mm (width per side-lip) = 300 mm.

extended lip location length

The lip location length of the sliding is 280mm. This can optionally be extended to 470mm. This option is often used to load / unload trucks that deviate from standard trailers. In cases where there are bumpers mounted on the back of the truck or the loading floor does not begin immediately at the back of the truck.

different building height

De The dockleveller DLE-NG NG has a standard height of ± 700mm. In some situations where the standard overall building height seems too high, for example to fit the DLE-NG dockleveller into an existing pit for replacement or in a pit which was made for a DLH-NG dockleveller, the overall height can be adjusted to ± 600mm.

Forklift brackets to platform

A standard dockleveller is equipped with two forklift brackets on top of the upper deck, which fit the forks of the forklift.
That is how the dockleveller can be loaded and unloaded.

sleeves for loading in a container

In the case the docklevellers need to be loaded in a container the forklift brackets cannot be used. For container loading we will equip the docklevellers with special rear forklift sleeves under the platform so the docklevellers can be loaded / unloaded into a container.

OPTion "SECURE LOAD" for container loading (inflatable cushions + EXTRA straps)

This option can only be selected in the webshop when the goods are to be loaded into a container and that will be done by us.
In order to ensure that the goods will not be damaged during transport overseas, the load will be fixed with extra straps and inflatable cushions are placed between the cargo and the wall of the container.
