4. The functioning of the bale grab
Mount the bale grab to a vehicle with a hydraulic system. The bale grab only works when it is
attached correctly to the hydraulic system of the vehicle.
One movement is possible with the bale grab:
The clamping of wrapped bales takes place with the help of the clamp arm that is powered
by a hydraulic cylinder.

5. Installation, starting up, adjustment
Check if the bale grab is undamaged and in good condition on delivery. Please
contact Meijer Holland if you notice any damages. Use the grab only if it is found
to be in good order and after this manual has been read.
5.1 After delivery
Place the bale grab on a solid and even ground.
5.2 Before moving the bales
1. Drive the vehicle in such a way to the bale grab that the mounting surface falls against the
mounting point of the bale grab.
2. Attach the bale grab to the vehicle.
3. Check the couplings for dirt. Only attach clean couplings to prevent dirt from entering the
system.
4. Connect the two correct hydraulic hoses of the vehicle to the two quick release couplings
above the mounting point of the bale grab. The upper hose is for clamping the bales and
the lower one is for releasing them.
5. Check for leakage.
6. Check the correct control of the cylinder from the hydraulic system.
7. Put the hydraulic system under pressure and test the bale grab by opening and closing
the hooks.
5.3 After having moved the bales
1. Place the bale grab with the vehicle on a solid and even ground.
2. Check whether the bale grab stands steady.
3. Disconnect the hydraulic hoses and check them for leakage.
4. Dismount the junction of the vehicle from the bale grab and drive away in reverse.
Store the grab in a dry and clean environment until the next use.

6. Operation and use
1. Drive the vehicle to the bale and open the clamp arms by putting the hydraulic system in
‘return’.
2. Keep driving until the bale is located between the two clamp arms.
3. Clamp the bale by operating the hydraulic system.
4. When the bale is clamped, put the hydraulic system back into ‘neutral’.
5. Lift the bale and drive the bale to the destination.
6. Let the bale sink to the (loading) floor and put the hydraulic system in ‘return’. By doing so,
the hooks open and release the bale.
7. Drive the vehicle away from the bale in reverse.
8. The bale grab is ready to grab and move another bale.

worn parts.
Check the hydraulic clutch, hoses and cylinders for leakage, wear and
damages. Let problems be fixed immediately by a competent mechanic.
At least once a week
Clean the collector of caked dirt and dust. When using a high pressure
