02.10 –Maintenance
The correct operation and long life of the ramp depend largely on the preventive maintenance work carried out.
Advanced maintenance may only be carried out by the INKEMA technical service or staff authorised by the latter.
This maintenance is carried out to ensure that the product conserves the safety and usage characteristics it had when
it was first installed.
All changes, repairs or manipulation of the product that fail to comply with these regulations will lead to the
cancellation of the one-year warranty term and the liability of INKEMA for the product will automatically end.
Continuous greasing, painting and vigilance is the best way to guarantee its performance for many years.
02.10.01 –Hydraulic oil
The hydraulic oil must be replaced every two years.
The oil must contain agents that prevent the formation of foam, oxidation and water absorption. If the winter
temperatures are very low, the oil must not be too thick and its viscosity index must remain stable at low
temperatures.
Never mix different oils, as the new oil may have a different resistance to oxidation and affect the life of the
original oil.
It is important to check the oil level every 6 months. The oil tank must be filled until it almost overflows from the
closing cap, in the lowest possible position.
The machine is supplied already containing T-15 oil
Hydraulic oil for ramps in refrigerated storerooms must have specific properties of use, in accordance with the
temperatures to which it is exposed. For this reason, if the need arises, the manufacturer must be informed about the
conditions in which the machine will be operating to ensure it contains the special oil.
02.10.02 –Grease points.
Every six months, check the grease points shown in the diagram

02.11 –Instructions for use
02.11.01 –Before use
Make a visual check to ensure the leveller is in perfect conditions of use.
Centre the vehicle against the rubber stops of the leveller.
Check that the vehicle is completely immobilised and blocked. (Switch off the engine, apply the handbrake and
place chocks on the wheels).
To raise the leveller to the load surface level, connect the manoeuvring circuit by turning the red section switch.
The green pilot light will come on.
To raise the leveller and open the lip, press the elevation button without releasing it.
If you stop pressing the button, the leveller will descend at a controlled speed, due to its own weight.
Raise the leveller until the lip starts to open. Once the lip is open completely, release the elevation button.
Let the leveller descend at a steady speed until it rests on the load surface of the truck.
Check that the whole width of the lip is resting on the load surface of the vehicle in an area NO smaller than
130mm.

Instructions manual RH11 and RH12 Inkema
V03 –2016
www.inkema.com
10
02.11.02 –During use
The dock leveller will merely rest on the load surface (truck). The hydraulic cylinders MUST NOT be blocked to
allow the leveller to adapt to the height of the load surface (which will vary, depending on the variation in the truck
suspension).
Check that the emergency stop is NOT activated and that the leveller is supplied with power.
VERY IMPORTANT:
It is strictly prohibited to perform loading and unloading operations with the emergency stop activated, or
while the leveller is not supplied with power.
Never exceed the maximum nominal load. (See its plate characteristics).
Ensure that the leveller continues to rest on the load surface during transit. If this is not the case, press the
emergency stop button immediately.
Fork-lift trucks must be driven with caution. The maximum transit speed calculated for the leveller is 10 km/hour.
02.11.03 –After use
Raise the leveller and close the lip before the truck leaves the loading position. To do this, press the elevation
button and raise the leveller just enough for it to clear the truck.
Release the button and wait for the leveller to descend at a steady speed and rest on the closed lip on the front of the
bedplate.
02.11.04 –Precautions during use
Check that the emergency stop is not activated.
Never exceed the maximum nominal load. (See its plate characteristics).
Before each manoeuvre check that no-one is in the working area.
Check that the leveller is resting properly on the load surface of the truck, with the entire lip coupled to a surface of
approximately 130 mm along its whole width.
The hydraulic unit has the sole function of making the necessary movements to manipulate only the dock leveller.
It must never be used to support and/or lift loads.
Before raising the device ensure that its movement is not blocked by other equipment. (Doors, etc...)
After completing the operation check that the lip is properly inserted in the closed leveller position.

05 –Installation
05.01 –Positioning in the pit
VERY IMPORTANT: When handling the leveller, always respect the occupation risk prevention legislation and
the regulations regarding safety, hygiene and health at work.
Place it in the pit with the help of a crane, fork lift truck or similar element, using the worm screws, and chains,
slings and similar items to lift it. With a load capacity equal to or greater than the weight of the leveller
Then unwind the electrical cable and pass it through the tube that is centred at the back the pit. Once the cable has
emerged at the other end of the tube, position the leveller correctly in the pit.
05.02 –Securing the leveller in the pit
05.02.01 –Securing in the case of an embedded model
Once the leveller is in the pit, check the following:
The separation between the sides of the leveller and the pit must be exactly the same at the front and back of it.
In the event of the separation not being equal in the pit, this must be at the rear part and not at the sides.
Considering that the height of the pit is usually about 10mm. more than the height of the leveller it is essential to
support the leveller base with plates or similar elements until the leveller is flush with the loading bay. The support
points are those marked with the arrows in the following diagram:
Place at least the following levelling plates in position:
- 2 at the front of the machine (which must coincide with the weld cords).
- 3 at the rear of the machine which must coincide with the bedplate head pipes.
- 1 at each cylinder application point.
Then weld the plates to the leveller and weld the ramp to the recessing subframe, as indicated:
Block it against the wall, if necessary.

Instructions manual RH11 and RH12 Inkema
V03 –2016
www.inkema.com
15
The weld areas are indicated in the following diagram:
- 2 weld cords with a throat of 6mm. and length of 200mm. coinciding with the points where the lip is
supported on the front of the machine.
- 5 weld cords with a throat of 6 mm. and length of 100mm., distributed and separated by 375mm at the rear
part.
6x100/375 (x5)
6x200 (x2)
05.02.02 –Securing in the case of a self-supporting model.
Once the leveller is in the pit, check the following:
The separation between the sides of the leveller and the pit must be exactly the same at the front and back of it.
In the event of the separation not being equal in the pit, this must be at the rear part and not at the sides.
These spacers have the mission of NOT allowing the sides of the bedplate to close against the mobile leveller, due
to the pressure exerted when concreting the paving in the premises; if this should occur, it would cause a serious
problem in the subsequent functioning of the machine.
The anchoring hooks are in a pack supplied with the machine.
Distribute 5 hooks at the rear, 3 or 4 at each side (depending on the machine length) and 2 at each pipe at the front.
Weld one end to the profile of the bedplate and the other end to the reinforced concrete notch.
Weld one end to the profile of the bedplate and then seal the sides with polyurethane foam.
Once all the lips are welded, seal the sides with polyurethane foam so that the concrete cannot penetrate into the
existing space. The platform will be ready for creating the formwork of the final paving in the loading bay.
Note: Floor of at least H250 concrete with a thickness greater than or equal to 200mm. Filling of perimeter with at least H250
concrete.

05.03 –Installing the electrical control panel
The electrical panel must be installed in the wall on the truck driver side, to allow the dock leveller operator to see
and talk to the driver if necessary. (See electrical control panel connections, page 17)
Secure the electrical panel box to the wall at the desired height and perfectly aligned with the output of the leveller
cables, approximately 1300mm from the floor.
Adjust the tube for the electrical cables to pass through at the existing distance between the panel and floor.
Secure the tube to the wall (using at least 3 brackets); it must be perpendicular to the loading bay floor and aligned
with the leveller output cables.
The plastic tube is delivered sealed to one of the two sides of the leveller bedplate.

05.04 –Completed installation
Eliminate the front strips joining the lip to the bedplate.
VERY IMPORTANT: Weld the lateral panels, removing the rivet that holds them in place and check their
movement and functionality.
Lastly, check the condition of the leveller paint, correcting any flaws (including the levelling plates).
The installation is considered completed when the installer authorised by INKEMA has filled in the respective
installation control sheet.

06 –Dismantling
06.01 –Dismantling an embedded leveller
VERY IMPORTANT: When handling the leveller, always respect the occupation risk prevention legislation and
the regulations regarding safety, hygiene and health at work.
To dismantle the leveller, it must be in the rest position.
Disconnect from the mains and also disconnect the electrical panel. Dismantle the electrical panel box and
electrical conduction tube.
Strap the front of the leveller to prevent it from opening when being handled. To do so, use at least 2 steel flanges
of 30x1mm.
Then cut all the welding attaching the leveller to the subframe, at the front and back.
Once the above tasks have been completed, remove the leveller from the pit.
This operation should be made using a crane or similar element, using chains, slings or similar elements to raise it.
With a load capacity equal to or greater than the weight of the leveller.
06.02 –Dismantling a self-supporting leveller
It is important to bear in mind that this type of leveller cannot be dismantled completely, as the bedplate is attached
to the loading bay paving using formwork.
VERY IMPORTANT: When handling the leveller, always respect the occupation risk prevention legislation and
the regulations regarding safety, hygiene and health at work.
Proceed as follows:
- With the leveller in the rest position, press the up/down button. The machine starts to rise. Just before the
lip starts to open, press the emergency STOP button turning the selection switch to the (0) setting.
- In this position, release the maintenance bar and place it in the operating position.
- Connect the power and press the up/down button (once). Let the machine rest on the bar.
- Turn off the power.
VERY IMPORTANT: Check that the maintenance bar is in the correct position, as the dismantling work must be
done inside the machine.
