Introduction

2200004 _7225 2018 04 20 English EN
Unfortunately, the majority of workplace accidents
occur due to thoughtlessness or carelessness.
These can be avoided by taking preventative
safety measures. No safety equipment or devices,
no matter how well constructed, is better than
machine operator care and observation.
Read through the instructions for use carefully and
make sure you understand the contents before using
Rototilt®. Poorly performed or incorrect handling and/
or assembly may result in serious or life-threatening
injury.
Observe the safety instructions contained in this
publication in order to protect Rototilt®and to prevent
personal injury.
Read and note all warning decals on Rototilt®.
The warning decals have a yellow background
with black text.
Do not permit untrained individuals to handle, repair
or perform maintenance on Rototilt®.
Otherwise refer to the base machine safety
instructions.
Description of warning texts
Warning texts are classied in three levels as shown
below, according to how serious the consequences
of an accident can be.
DANGER!
Indicates an accident risk if the instruction
is not followed. Accidents will lead to
serious personal injury, death and/or
serious damage to property.
Warning!
Indicates an accident risk if the instruction
is not followed. Accidents may lead to

Grapple module
IMPORTANT!
The grapple module is only intended for
installation on Rototilt®units from Rototilt
Group AB.
Before use
• Before use, check that no-one is within the base
machine’s risk area. Increase the risk area when
handling long objects with the grapple.
• Check that the tool used in combination with
Rototilt®does not interfere with the grapple
module. In certain cases, it may be necessary
to adjust the tool.
IMPORTANT!
Read through the Handling chapter.
IMPORTANT!
Information on the grapple module
operating controls can be found in the
control system’s instructions for use.
IMPORTANT!
Read through the instructions for use
carefully and make sure you understand
the contents before using the grapple
module.

During use
• Never stand or pass beneath a raised object.
• Risk of falling objects.
• Crush risk.
• An installed Rototilt®and grapple module
changes base machine geometry. Risk of
collision between the tool and the base machine.
• An installed Rototilt®will alter base machine
weight parameters. The values specied in the
base machine lifting table must be reduced by
the weight of the Rototilt®.
• Exercise caution when handling long objects
with regard to the forces of inertia and the
extended risk area.
• The grapple arms may not be used for anything
other than gripping objects suitable for lifting.
MAY NOT BE USED FOR LIFTING PEOPLE.
• Never attach chains or straps around the
grapple arms for lifting.
Use the base machine lifting hook instead.
• It is not permitted to lift weights greater than
the lifting capacity stated in the machine
specications when using the Rototilt®and
grapple module.
See base machine instructions for use.
• Never exceed the maximum lifting capacity.
See information plate.
• Always bear in mind the risk of dropping the load
when lifting objects with the grapple arms.
• When the grapple is not in use, keep the grapple
arms retracted.
IMPORTANT!
Due to the parallel hydraulic connection,
the grapple arms may move at di󰀨erent
rates.
The grapple arm with the lowest load will
move rst.

Description
General
The grapple module is a hydraulically driven tool
intended for installation and use on Rototilt®units
from Rototilt Group AB.
Tools connected below a Rototilt®unit and the
grapple module are assumed to be of a type
normally used for work with the base machine.
The grapple module is installed on the quick coupler
and does not a󰀨ect the unit’s total installation height.
The grapple module is a Rototilt®accessory
intended for use for light grappling and handling
work.
The grapple module is used as a supplement to
other tools, but does not replace a grapple tool
connected beneath the tiltrotator.
Warning!
Never exceed the maximum lifting
capacity.
See information plate.
Other types of use may not take place without the
manufacturer’s approval.
The grapple arms are connected in parallel
hydraulically to the extra function performed by the
swivel. Operation is controlled using the appropriate
levers.
The G-AG/RG series grapple cylinders are tted with
pilot controlled non-return valves or load holding
valves to maintain hydraulic pressure during gripping
operations.
IMPORTANT!
Valve functions form an important part of
the safety system.

Grapple module operation
The grapple module’s two hydraulic cylinders are
connected in parallel hydraulically and are operated
via the extra outlet on the Rototilt®quick coupler.
Oil ow in one direction opens the grapple arms,
while oil ow in the other direction closes them.
Note which control levers operate the functions
“open grapple alarms” and “close grapple arms”
respectively.
Information concerning the control levers that
operate the grapple module can be found in the
base machine control system manual.
Extra function operation may di󰀨er from unit to unit
depending on the control system the Rototilt®is
equipped with.
Extra function
(*does not apply to G400B and RG series)
It is possible to connect an extra function on grapple
modules G600B, G800B, G850B, G910 and G1060.
To use the extra function, turn the nuts for the
directional valves (located in the rear part of the
cylinders) in direction E. See Fig. 1.
IMPORTANT!
The directional valves on both cylinders
must be redirected.
Turning the nuts on the directional valves switches
between operation of the grapple function and any
other hydraulically driven tool connected to the extra
function outlet. Use a wrench to turn the nuts.
To use the extra function, remove the plug and
connect the connection. See Figure 2.
For other information regarding the extra function
and other Rototilt®functions, see the Instructions
for use for Rototilt®.

Extra function G400B
An extra function can be connected on model
G400B, if a valve block with the ability to close
the “grapple open channel” is installed.
To connect a hydraulic tool to the extra function,
do as follows:
1. First retract the grapple arms to their closed
position.
2. Then turn the bolt on the directional valve
clockwise to close the grapple open function.
See Figure.
3. Remove the plugs from the outlets and connect
the hydraulically driven tool.
WARNING!
The extra function is always pressurized.
Even if the grapple module is used, the
extra function is pressurized in both
directions.

Grapple module removal
1. Rest the Rototilt® at against the ground.
Run the grapple arms out to the open position
and then switch o󰀨 the base machine.
Disconnect the hydraulic hoses between
the base machine and the Rototilt®.
2. Removes the four attachment bolts from
the grapple frame. Allow the bolts to remain.
3. Remove the hydraulic hoses between the
grapple module and the quick coupler.
4. Remove the four bolts fully, carefully tap the
back of the cylinder protection while pulling
the grapple module and a quick coupler apart.
5. On some models it is necessary to remove
the rear shank locks before it is possible to
pull them apart.
On the AG/RG series, it is necessary to remove
the rear stay before the grapple module is
removed from the quick coupler.
6. Install the plate, adapter and cover for the
hydraulic hoses and plunder the connections.
7. If the tension pins are still in the quick coupler,
remove them with the aid of pliers.
Then fasten the protection plates. Ideally,
stow the tension pins in the grapple module
attachment holes (to be ready for grapple
module reinstallation).

2200004 _7225 2018 04 20 English EN
Grapple module installation
Perform installation in reverse order.
See tightening torque table.
Connection
In order for the grapple module to function correctly,
attachment must take place as illustrated.
See Figure below.
Model Tightening torque
G400B 130 Nm
G600B,RG600 330 Nm
G800B, RG800 330 Nm

Danger!
In the case of incorrect connection,
gripping force may be lost and the load
dropped.
Dropping a load may result in damage to
property and the risk of personal injury or
serious personal injury.
