A trademark of <strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong><br />

<strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong> is the world biggest manufacturer of hydraulic retractable lift truck forks,<br />

which are manufactured under the brand name KOOI Reachforks ®. The telescopic forks were<br />

introduced in 1980 by KOOI BV, manufacturer of the collapsible fork-lift truck, the so-called Kooi-AAP,<br />

but were manufactured by <strong>Meijer</strong> BV. From November 2000 <strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong> (division of<br />

<strong>Meijer</strong> Holding) along with production is also responsible for the marketing and sales of the telescopic<br />

forks.<br />

With your new telescopic forks you have acquired a reliable product that meets the highest quality and<br />

consumer requirements. Before you start using the telescopic forks you should know how to use the<br />

telescopic forks correctly. This manual tells you everything that you must know about the telescopic<br />

forks. It allows you to optimally operate the telescopic forks. Moreover, our After Sales Department is<br />

always ready to render you technical support.<br />

KOOI Reachforks ® meet the following quality standards:<br />

3. Introduction<br />

The KOOI Reachforks ® are hydraulic retractable lift truck forks. They are designed in such a way that<br />

minimum maintenance is necessary, which allows to reach the most possible life span. To achieve<br />

this it is really important that the maintenance is performed according to the instructions of the<br />

manufacturer. The aim of this instruction manual is to acquaint you with the telescopic forks. We also<br />

advise you to study this instruction manual carefully before you start mounting the telescopic forks and<br />

as you operate them later on.<br />

The manufacturer reserves the right to modify specifications without prior publications. Because we<br />

are constantly striving to improve the product it may happen that the pictures in this manual do not<br />

coincide with the telescopic forks that you have acquired. That is why it is important to mention the<br />

type and serial number as you order spare parts or inquire for information. In the appendices there are<br />

figures and specification tables of all types of telescopic forks, so that you may state the<br />

corresponding article number when you order spare parts.<br />

4.2. Explanation of type plate<br />

The type plate is the plate that is located on the upper side of each telescopic fork. The type plate is<br />

mounted on the left as well as on the right fork. Both left and right must be seen from the positions of<br />

the fork-lift truck driver. The type plate contains important information about the technical<br />

specifications of the telescopic fork. Figure 4.2 shows an example of a type plate. The letters in the left<br />

plate can be found in Table 4.1 that represents the description and the measuring unit. The right plate<br />

is an example of how the type plate can be filled in.<br />

Often A at Figure 4.1 contains the type of the telescopic fork. From the type code again various<br />

information can derived. Table 4.2 gives the description of the various sections of the type code.<br />

4.4. Capacity<br />

The type plate, which is mounted at the upper side of the telescopic fork, shows among other things<br />

the maximum carrying capacity per telescopic fork. This data is also engraved on the side of the<br />

telescopic fork. With the following load diagram the capacity per telescopic fork or per couple of<br />

telescopic forks can be defined for each load distance. The correction factors are shown vertically and<br />

the load distances are shown horizontally counted in mm from the front side of the back of the fork. On<br />

the following page an example of the operation is given.<br />

We take as an example the filled in type plate from Figure 4.2 with the type RE4-35-1350-1000. The<br />

maximum capacity of both telescopic forks is 35 x 100 = 3500 kg at a load centre of 600 mm. That<br />

means that the maximum capacity of one telescopic fork is 3500 / 2 = 1750 kg at a load centre of 600<br />

mm. If the telescopic forks are extended you must look at Figure 4.3 to calculate the new maximum<br />

capacity at the corresponding load centre. If the load centre lies e.g. at 1200 mm then Figure 4.3<br />

shows here a correction factor of 0,5. So the maximum capacity of this telescopic fork at a load centre<br />

of 1200 mm is 1750 x 0.5 = 875 kg.<br />

!<br />

Warning:<br />

Figure 4.3 applies only to the telescopic forks. The residual capacity<br />

of the fork-lift truck with the telescopic forks must be provided for by<br />

an authorised fork-lift truck dealer.<br />

5. Safety<br />

A trademark of <strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong><br />

Safety starts with the fork-lift truck driver. That is why we advise that the driver of the fork-lift truck<br />

possesses a recognized diploma of a fork-lift truck driver.<br />

Furthermore it is important to observe the following safety instructions:<br />

1. Do not load the telescopic forks above the values defined by the manufacturer, concerning lifting<br />

capacity and load centre.<br />

2. Pull the load in if it is possible. ATTENTION, telescopic forks of the type REE are extension forks,<br />

never pull them in with a load on.<br />

3. Retract the telescopic forks during driving if there is no load on them.<br />

4. Always drive with the telescopic forks in the lowest possible position.<br />

5. Never drag the telescopic forks over the ground when driving.<br />

6. Never allow riding on the telescopic forks or load.<br />

7. Telescopic forks with defects may not be used until they are expertly repaired or replaced.<br />

8. Before you start performing service work on the telescopic forks you must make sure that the fork-<br />

lift truck is switched off and that there is no more pressure in the hydraulic system (remove the<br />

ignition key).<br />

9. The load should always be carried by the two telescopic forks as proportionally as possible.<br />

10. Always keep the exterior of the outer forks free from grease and oil.<br />

All abovementioned points must be read and understood by the fork-lift driver.<br />

!<br />

!<br />

!<br />

Warning:<br />

Never exceed the maximum carrying capacity of the fork-lift truck,<br />

irrespective of the carrying capacity of the telescopic forks.<br />

Warning:<br />

Never walk under the telescopic forks.<br />

Warning:<br />

Applicable only to telescopic forks with a high<br />

palletstop (type Y2 or Y3), that with a retracted<br />

fork is at a distance of 50mm or less from the<br />

back of the fork (from palletstop front to the front<br />

side of the back of the fork).<br />

When retracting avoid squeezing limbs or goods<br />

between the back of the fork and the palletstop.<br />

This may result in serious injury or damage of<br />

goods!<br />

6. Instructions for use<br />

Telescopic forks offer the possibility to load and unload a lorry from one side, to stack goods at<br />

warehouses double-deep, to pick up two pallets at a time, and they may be used as extension forks<br />

when operating with pallets of various dimensions.<br />

The telescopic forks are easy to mount and to demount. The telescopic forks must be tuned to the<br />

fork-lift truck for the purpose that they are intended for. The final capacity must be defined by an<br />

authorised fork-lift truck dealer. On the type plate of the fork-lift truck the capacity must be adapted to<br />

the new combination of fork-lift truck and telescopic forks. It is advisable that the fork-lift truck driver is<br />

professionally trained in the use of telescopic forks.<br />

!<br />

!<br />

!<br />

Attention!:<br />

The contact of the telescopic forks with the ground, during driving and<br />

during pick-up of a load, must be avoided as far as possible. This<br />

prevents wear at the bottom of the outer forks. To prevent this wear<br />

wear-resistant pads can be welded to the underside of the outer<br />

forks.<br />

Attention!:<br />

When moving in reverse take care that the telescopic forks do not<br />

drag over the ground. This can result in damage to outer fork as well<br />

as to piston rods.<br />

Attention!:<br />

Telescopic forks of the type REE are extension forks. This type of<br />

telescopic forks is not intended to be extended and retracted when<br />

loaded. Retract or extend the telescopic forks to the required length<br />

before picking up a load.<br />

7. Mounting instructions<br />

A trademark of <strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong><br />

In this chapter first of all several prescriptions are listed that must be observed during service work on<br />

the telescopic forks, irrespective of the type. In 7.2 the telescopic forks with a separate flow divider are<br />

dealt with. 7.3 tells about what can be done to reduce wear at the bottom of the telescopic forks.<br />

7.1. Prescriptions<br />

There are several prescriptions that must be observed during mounting operations, inspection or<br />

maintenance of the telescopic forks.<br />

During all service work on the telescopic forks, the forklift truck should be switched off and the ignition<br />

key must be removed.<br />

When performing maintenance the hydraulic system of the fork-lift truck must have no pressure.<br />

Position the telescopic forks on the convenient ergonomic height to prevent backaches.<br />

Wear safe working clothes, shoes and safety goggles.<br />

When disconnecting the telescopic forks from the fork carrier the connection couplings of the<br />

telescopic forks must be unplugged to protect the hydraulic system from dirt that might get inside.<br />

Nothing can be welded to the telescopic forks without written consent of the manufacturer. If<br />

something is welded to the telescopic forks without written consent the guaranty on the telescopic<br />

forks terminates.<br />

7.2. Mounting instructions for telescopic forks with a separate flow divider<br />

(RE2, RE4, REE2 and REE4)<br />

To achieve the most optimal operation of your telescopic forks after the mounting you should observe<br />

the following mounting instructions:<br />

1. On the type plates of the telescopic forks there are an L and an R displayed. Mount these<br />

telescopic forks accordingly on the right and on the left sides viewed from the position of the fork-<br />

lift truck driver.<br />

2. Slide the telescopic forks onto the fork carrier and make sure that the locking pin fits into one of<br />

the fork carrier notches.<br />

3. The flow divider must be mounted on a safe and protected spot.<br />

4. Connect the enclosed hydraulic hoses of the telescopic forks and the hoses of the fork-lift truck<br />

according to Figure 7.1 and pay attention to the letters that are engraved at the top of the fork as<br />

well as in the flow divider.<br />

5. Make sure that the hydraulic connections are carefully tightened and secured.<br />

6. The maximum allowable working pressure of the telescopic forks is 200 bars.<br />

7.2.1. Recommended oil flow and hose diameter<br />

A trademark of <strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong><br />

Table 7.1 shows what the recommended hose diameter is at a certain oil flow for the telescopic forks<br />

with a separate flow divider. The recommended flow divider type is also shown.<br />

Type of telescopic fork Recommended oil flow Recommended hose Flow divider type<br />

(L/min)<br />

diameter<br />

RE2/REE2/RE4/REE4 8 – 25 ¼” RE0100000<br />

Table 7.1 Which hoses and flow divider to use for which oil flow<br />

If the oil flow is more than 25 l/min, it will have little effect on the speed. It is also recommended to stay<br />

below this value, so that the pump does not constantly have to deliver the maximum pressure and so<br />

no oil pumps through the safety valve to the tank. This will also require less energy.<br />

7.2.2. Putting the telescopic forks into operation<br />

First you should make sure that there is no more air in the system. You can do this in the following<br />

way:<br />

Extend and retract the telescopic forks ten times.<br />

Bend the mast of the fork-lift truck several times forward and backward.<br />

Extend and retract the telescopic forks ten times.<br />

Then control if the hoses can go all over long enough and check if the system leaks no oil.<br />

7.3. Protecting the telescopic forks<br />

To avoid that the telescopic forks come into contact with the ground we advise to place a plastic<br />

sleeve on the lift cylinder in such a way that the telescopic forks just do not contact the ground. The<br />

lifting chains of the fork-lift truck can be somewhat shortened, which will have the same effect. Always<br />

consult your dealer or manufacturer if you want to perform such a modification.<br />

8. Inspection and maintenance<br />

The telescopic forks operate with a closed self-lubricating hydraulic system. The telescopic forks are<br />

delivered with Rando HD 32 hydraulic oil.<br />

The servicing that must be performed to keep the telescopic forks in good condition is very limited.<br />

What is important is that the servicing is carried out in time and correctly.<br />

Check the telescopic forks each day for damage and oil leakage. If there is indeed damage or leakage<br />

this should be reported to the person in charge. During all service work on the telescopic forks the<br />

fork-lift truck should be switched off, the ignition key must be removed and there may be no more<br />

pressure in the system.<br />

Consult the maintenance schedule for further inspection. In some cases it may happen that the<br />

maintenance schedule must be adjusted, for example in extra polluted environment. Plugs should<br />

then be replaced more often, in particular the wiper ring.<br />

The telescopic forks must be tested again minimum once per year by a specialist according to the ISO<br />

5057 norm. The results of the test should be kept in a test book.<br />

In case parts of the piston or the cylinder head must be replaced, this should be carried out by a<br />

skilled person or contact an officially authorised importer listed on the website<br />

(www.telescopicforks.com).<br />

8.1. Maintenance schedule<br />

Table 8.1 shows which parts must be controlled, what actions must be taken and when this must be<br />

done. The numbers of the description correspond to the telescopic fork in Figure 8.1 (page 16).<br />

14 © MEIJER SPECIAL EQUIPMENT 2005


Here comes a commentary on the maintenance schedule from Table 8.1:<br />

A trademark of <strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong><br />

1. As lubricating grease we recommend Novatex EP 2, this is a special type of calcium grease for<br />

lubrication of heavy loaded sliding parts that protects against wear and corrosion.<br />

2. In case of leakage in the curve of the inner fork immediately demount the telescopic forks from the<br />

fork-lift truck and take contact with your dealer. In case of leakage of couplings tighten or replace<br />

them.<br />

3. When the wear resistant strips are thinner than 1,5 mm, they should be replaced or filled up with<br />

filling plates. For REE: When the hardened wear pad at the bottom of the telescopic fork is so<br />

worn-out that it is level with the bottom of the outer fork, it should be replaced. This is to prevent<br />

excess wear of outer and inner forks. The remainder of the old wear pad must be removed and<br />

the new wear pad must be welded under the telescopic fork according to the welding figure in<br />

Appendix 13. ATTENTION: Take out interior work (piston, piston rod and cylinder head) from<br />

telescopic fork BEFORE welding.<br />

4. When the hardened wear pad in the heel of the outer fork is level with the underside of the outer<br />

fork or is even thinner than the original thickness of the outer fork then the outer fork should be<br />

replaced.<br />

5. Eventual dirt in the front part of the outer casing can affect the stroke length of the telescopic<br />

forks. Depending on the application it may need to be controlled either more or less often.<br />

6. The wiper ring can be easily controlled if the outer casing is taken off (for instructions on removing<br />

the outer fork, see par. 8.4).<br />

7. The international standard ISO 5057 must be applied for checking your telescopic lift truck forks,<br />

except for paragraph 5.6.1 because the inner fork may not be subject to wear.<br />

8.3. Instructions for replacing hydraulic parts<br />

1. Set the telescopic forks on the hip level, bend the mast forward and remove the ignition key from<br />

the contact.<br />

2. Take the outer fork off by removing the spiral clamping bushes (be careful not to damage the<br />

piston rods).<br />

3. Unscrew the hose couplings a little off the hose above on the rug of the telescopic fork so that the<br />

piston rods do not pull vacuum when demounting the telescopic forks.<br />

4. Unscrew the locking screw situated between the cylinder heads.<br />

5. Place a reservoir under the telescopic forks. Use the cylinder head key to unscrew the cylinder<br />

heads. Take care that the right cylinder head (as viewed from the position of the diver) is<br />

unscrewed first, along with the plastic bung under the locking screw.<br />

6. Carefully pull out the piston rods.<br />

7. The piston can now be unscrewed. To avoid damage to the piston rod it must be clipped onto the<br />

mounting clip. The cylinder head can now be unscrewed from the piston rod.<br />

8. Replace the parts.<br />

9. Remove Loctite from the screw thread of the piston rod.<br />

10. Clean piston rod and screw thread with Loctite 7063.<br />

11. The cylinder head can now be put on the piston rod again.<br />

12. When mounting the piston on the piston rod it must be locked with Loctite 270.<br />

13. Keep the piston rod (along with piston and cylinder head) straight before the cylinder and tap it<br />

carefully directly to the inside.<br />

14. Smear the screw thread of the cylinder head with Copaslip.<br />

15. Tighten again the cylinder head carefully with a cylinder head key.<br />

16. As all piston rods sit again in their place, the locking screw must be screwed up again above the<br />

plastic bung.<br />

17. Now the hose couplings of hose must be screwed up.<br />

18. Take care that the piston rods should be unscrewed for about 150 mm.<br />

19. The outer forks can be now mounted again. Take care that the clamps of the piston rods are<br />

located exactly under the holes in the outer fork. Insert a screwdriver or a bolt in one hole and hit<br />

the new spiral clamping bushes in the other gat with a hard hammer. The screwdriver or the bolt<br />

can be taken from the hole and now the spiral clamping bushes can be knocked in here.<br />

20. Start the fork-lift truck and extend and retract the telescopic forks several times.<br />

8.4. Ordering spare parts<br />

A trademark of <strong>Meijer</strong> <strong>Special</strong> <strong>Equipment</strong><br />

With the types RE4-25, RE4-35 and RE4-45 of the Power Range and with a stroke (see Paragraph<br />

4.3.) of more than 1200 mm a rod thickness of 20 mm is operated with, this should be taken into<br />

consideration when ordering pistons, cylinder heads and plugs. Besides, deviations in bore diameter<br />

are engraved on the side of the telescopic forks.<br />

In case a separate piston, cylinder head or only a plug, wiper ring or guide ring must be ordered, it is<br />

recommended to order them mounted and all together to avoid problems at mounting.<br />

For ordering the piston rods instead of XXXX in the article number the length of the piston rod must be<br />

filled in. The length of the piston rod is equal to stroke of the telescopic forks plus 100 mm.<br />

For ordering stop elements for upper blocks (stop pin, catch, spiral clamping bush in aid of catch and<br />

compression spring) or hydraulic screw couplings the serial number of the telescopic fork must be<br />

mentioned.<br />

For ordering wear pad for the REE2/REE4 forks instead of the YYYY in the article number the length<br />

of the telescopic forks minus 196mm must be filled in. Besides, for ordering wear pads and outer<br />

casings for the REE/REE4 forks it is recommended to mention the serial number of the forks.<br />

It should be taken into consideration that the RE2/REE2-forks contain 1 cylinder per telescopic fork<br />

and the RE4/REE4-forks contain 2 cylinders per telescopic fork.<br />
