Bale grab Jumbo CKM1 ‒CKM2 ‒CKM3 –EN 4
1. Introduction
The bale grabs Jumbo CKM’s of Meijer Holland are designed to be attached to a telescopic
handler, front loader, wheel loader or forklift (hereinafter referred to as ‘vehicle’) in order to
grab and transport wrapped bales over a short distance). The hydraulic hoses of the bale
grab are to be attached to the hydraulic system of the vehicle.
It is important to read the manual carefully before using the machine. Should this
not be the case, there can be the risk of serious injury or death for the user and
damages to the environment. Moreover, there is the risk of damage to the materials
or to the machine. Therefore it is essential that you follow the instructions of this
manual.

3. Safety precautions
The following precautions are important to prevent injuries and damages.
1.
Read the manual before use.
2.
Only experts should (dis)mount the bale grab.
3.
Only experts should operate the bale grab.
4.
Use the bale grab only for bales.
5.
Check whether the hydraulic system is working well right after having mounted the
bale grab.
6.
Follow the instructions for use (chapter 6).
7.
The working area of the machine is 5 metres:
no persons are allowed within that range!
8.
Operate the bale grab exclusively from the cabin of the vehicle.
9.
Mind the rules for max. load (chapter 2).
10.
Be aware of oil leakage:
check the hydraulic hoses and cylinders at least once per day.
11.
Replace damaged or worn wires and cylinders immediately.
12.
Follow the instructions for maintenance (chapter 7).
13.
When driving longer distances or on a public road:
no bales are permitted in the bale grab!
14.
Drive straight backwards after having placed the bales.
when the clamp arm is not lifted above the placed bale, the stack of bales can fall
over.
15.
While reversing:
make sure that there are no people behind the vehicle.
Build the stack of straw and hay bales in a stable way so that it cannot fall over.
The driver must be aware of the rules that apply to the lifting and hoisting of
heavy loads.

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.
For all three types of the bale grab - CKM1, CKM2 and CKM3 - the clamping of a bale takes
place with a clamp arm that is powered by a hydraulic cylinder. Each clamp arm has one
cylinder. This movement can be seen in the images below.
The Jumbo CKM3 offers the possibility to adjust the distance between the clamp arms.

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 oil 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 bale grab in a dry and clean environment until the next use.

6. Operation and use
1. Drive the vehicle in such a way to the bale that the bale is located right under the bale
grab (with the CKM3 the first bale has to be located right under the middle clamp arm).
2. Let the bale grab sink until the front frame leans against the bale.
3. When the frame pushes against the bale, the hydraulic system can be operated. The rear
frame moves towards the bale.
4. Once the bale is clamped, put the hydraulic system back into ‘neutral’.
Make sure that the rear frame has enough space above the ground so that it does not
drag on the ground.
5. Lift the bale and drive the vehicle to the place of destination or to the next bale.
6. For the second and third bale: drive again in such a way to the bale that the still empty
clamp arm hangs right above the second bale.
7. Let the bale grab sink so that the front frame leans against the bale. Hold the bale grab in
such a way that the wheel will be pushed up. By doing so, the hydraulic circuit is pushed
under pressure the clamp arm will be closed.
8. Let the bale (bales) sink to the loading floor and put the hydraulic system in ‘return’. Lift
the bale grab up.
9. Drive the vehicle away from the bales in reverse.
10. The bale grab is ready to grab and move another series of bales.
Use Jumbo CKM1, 2 and 3

7. Maintenance
Regular maintenance extends the life span. The bale grab needs relatively few maintenance.
Maintenance schedule
Before every use
Check the bale grab for damages and wear. Replace damaged or worn
parts immediately.
Check the hydraulic clutch, hoses and cylinders for leakage, wear and
damages. Let problems be fixed immediately by a competent mechanic.
At least once per
week
Clean the bale grab of caked dirt and dust. When using a high pressure
washer, avoid the electrical parts.
Put grease on the grease nipples. At extensive use:
after every 8 working hours add a bit of grease (0,86 grams per grease
nipple).
Check the clamp arms for damages in order to prevent damages of the
wrapped bales.

8. Problems and solutions
The bale grab has relatively few moveable parts and damages are unlikely to occur when
used properly. Repair or replace damaged or worn parts immediately. Spare parts are
available at Meijer Holland.
Turn off the engine of the vehicle while you are fixing one of the below-
mentioned problems.
Turn off the power supply during welding.
Hydraulic fluid is a poisonous liquid that is harmful to the environment. Never try
to shut a leak with your hand. Fluid under high pressure easily penetrates
through skin and clothing and can cause serious injuries.
Problem
Possible cause
Solution
The clamp
arm(s) is/are
not moving.
The hydraulic system of the bale grab is
not attached to the hydraulic system of
the vehicle.
Attach the two hoses.
The hydraulic circuit of the bale grab is
not attached correctly.
Exchange the wrongly attached
hydraulic hoses.
Malfunction in the hydraulic system of
the vehicle.
Consult the manual of the vehicle.
The clamp arm(s) or cylinder(s) is/are
blocked.
Look for the blockade and remove
it.

9. Environment and disposal
The bale grab has a hydraulic circuit that contains hydraulic fluid, a poisonous liquid that is
harmful to the environment. Regularly check the bale grab for leakage and replace damaged
or worn parts immediately.
9.1 Disposal of the bale grab
Drain the hydraulic system and let the fluid be disposed by an authorised company.
The rest of the bale grab is made of coated steel and can be disposed of as crap.
