Bale grab Rambo 3 - EN 4
1. Introduction
The bale grab Rambo 3 has a fixed frame
1
and is 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 straw or hay bales over a short distance. The bale grab is equipped with a
hydraulic circuit that is to be connected to the hydraulic system of the vehicle.
It is important to read the manual carefully before using the machine. There could
be a risk of serious injury or damage to the environment if the bale grab is not used
properly. Moreover, damages to the material or to the machine might occur. It is
therefore important to follow the instructions of this manual.

There is also a standard Rambo available with a hinged frame: the Rambo 6K.

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 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 meters:
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.
Take into account that the sight of the driver is limited when there are bales in the bale
grab.
14.
When driving longer distances or driving on a public road:
no bales are permitted in the bale grab!
15.
When 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.
The clamping of the bales takes place with the help of hooks that are powered by
hydraulic cylinders. This movement can be seen in the figures below.
The Rambo 3 is equipped with three clamp arms that can grab one bale respectively.
Each clamp arm consists of four hooks and one cylinder.
One clamp arm does not have a hydraulic device; this one grabs the first bale.
The two other clamp arms do have a hydraulic advice.
The bales can be grabbed separately as well as simultaneously.

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 bale 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. Attach only 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 moving 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.

6. Operation and use
1. Drive the vehicle in such a way to the first bale that the bale grab without the device hangs
right above the bale.
2. Let the bale grab sink until the frame touches the bale.
3. Clamp the bale by closing the hooks. Put the hydraulic system back in ‘neutral’
afterwards.
4. Lift the bale and drive to the place of destination or to the next bale.
5. For the following bales: Drive again in such a way to a bale that the still empty clamping
hooks hang right above the bale and the frame touches it. Hold the grab in a way that the
wheel is pushed upwards. The valve opens and the bale will be clamped.
6. Let the bales sink to the loading floor en put the hydraulic system in ‘return’. By doing so,
the hooks open and the bales are released. Lift the bale grab up.
7. The vehicle can now be driven away from the bales in reverse.
8. The bale grab is ready to grab and move another series of bales.
Use of the Rambo 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.
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 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).

8. Problems and solutions
The bale grab has relatively few moveable parts and hardly any wear occurs when used
properly. Repair or replace damaged and 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 hooks are
not moving.
The hydraulic circuit 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 hooks or the axes on which they
are attached 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 scrap.
