Safety instructions and safety rules
MULTILIFT XR hooklift equipment was developed for the loading, unloading, tipping
and transporting of removable containers/bodies on vehicles. All other use of the Multilift
hooklift equipment is strictly forbidden. Multilift accepts no liability whatsoever with regard
to such other use.
The hooklift equipment meets all safety and stability standards that apply at the moment
of its delivery from the factory. Use the hooklift equipment only if it is in good condition,
and only for the purpose for which it was designed and in accordance with the instructions
and guidelines specied in this manual.
Cargotec Finland Oy Multilift accepts no liability whatsoever for any loss or damage caused
by the failure to strictly adhere to the safety instructions specied in this manual or due
to carelessness during the operation, adjustment, maintenance or repair of the hooklift
equipment. Depending on the specic working conditions, additional safety instructions may
be required. Contact your Multilift dealer immediately if you have encountered an unsafe
situation with XR hooklift equipment that is not described in this manual.
Safety during use - general
The driver must be familiar with the contents of this manual and should strictly follow the
directions and instructions. He must see to it that his XR hooklift equipment is technically
in perfect condition. Control of the suspension, condition of the tyres, tyre pressures, weak
or poor condition of the container or unsuitable loading of it, are all his responsibility. The
driver must handle the XR equipment with care. For example during loading and unloading
the front wheels of the truck must not be lifted up from the ground.

XR14S/16S/18S/21S/26S/30S
XR hooklift equipment may only be used when sitting on the driver´s seat.
If it is necessary to leave the cabin during loading, unloading or tipping,
always engage the parking brake and disengage the power take-o󰀨.
See instructions for safe radio use on the next page.
In the vicinity of the control units there must be no obstacles or loose objects that might
accidentally activate unit´s functions.
If the equipment has not been used for two weeks or longer, all safety functions must be
checked before the equipment is used again.
Avoid the unnecessary use of the main pressure relief valve. Heating up of the oil reduces
the quality of it and results in shorter life span of retaining rings and gaskets.
In subzero temperatures (<32°F) it is recommended to let the pump idle for around 1 minute
in order for the hydraulic oil to be warmed up
During the use of the equipment the engine noise will increase due to additional loading.
Noise level will also increase if the container is pulled along the ground during loading or
unloading of it.
When the equipment is used carefully and in a sensibly planned manner, the noise level
can be kept lower.
Take care that the truck or the hooklift is not overloaded. Observe the factory data for
the truck with regard to maximum permissible axle load/GVW. See also the axle load
calculations!
Strong winds will have an e󰀨ect on the operation during loading, unloading or tipping of
the container.
If several successive containers switches are performed, the hydraulic oil may
overheat >140ºF (60ºC) making it necessary to install an oil cooler to the system.

Safety regulations
WARNING
The driver must apply the parking brake before leaving the
cabin to manoeuvre the hooklift by radio control. Otherwise the
vehicle may start mowing during loading/unloading.
WARNING
When loading/unloading is done on sloping ground, the driver
must sit in the cabin and operate the brakes of the vehicle.
WARNING
The driver must use great caution when loading/unloading
from outside the cabin because he/she may e.g. be standing in
the danger zone described above.

Working area
Load or unload only where there is su󰀩cient space; this also applies to free height. There
must be at least 33 ft (10 m) free space at both sides of the vehicle.
Check the vicinity for possible dangers.
When loading, the container must be placed in line with the driving direction of the truck.
If working in the dark, use working lights shining backwards in addition to the standard
truck lights.

It is the responsibility of the driver to ensure that there are or there will be no other persons
within the danger zone of the working area. It is strictly forbidden for anybody to be close
to the truck or the container.
Tip Mark out the working area, for example, with cones.
Tip Ensure that the warning buzzers are operational (remember the night time
limitations)
In case of emergency:

Safety instructions and maintenance
Always follow the maintenance instructions and use only original Multilift spare parts.
See chapter Maintenance.
Container
The demountable body can be a container, tank, gravel body, body for transporting
machinery etc. according to standards (e. g. DIN 30722, SFS 4417, SS 3021 or CHEM).
Check to be sure that the container is suitable for the load to be transported. Generally each
container has a model plate (ID) on which the length and permissible load are specied.
Before picking up the container, check that the hook height (H), tunnel height (T) and the
width (W) correspond with the XR hooklift dimensions and that the notches for the body
locks are in correct positions.
If there is even the slightest doubt of the container dimensions, measure them rst in order
to prevent the equipment and the container from being damaged.
Gripping height (H), tunnel height (T) and width (W) of the container can vary from one
container to another. Note that they are country specic dimensions. If there is doubt about
the origin of the container, the tunnel height and width must be checked in order to ensure
that they are compatible with those of the Multilift equipment.
Country specic standard dimension table of the container is on the next page.

Country specic standard dimension table of the container is on the next page.
If your country is not mentioned on the list, check the matter in your hooklift equipment
technical specications.
The condition of the container must be checked regularly. Especially if you are going to
use a type of container with which you are not familiar. In particular, check the condition
of the locking points and the condition and position of the lifting hook.
The maximum allowed wear of the lifting hook is 10 % from its nominal diameter. Nominal
diameter must be checked with the hooklift equipment supplier.
The longitudinal rails at the bottom of the container are under heady burden. Carry out
daily checks of these components for wear or damage.
If the container is frozen to the ground, do not pull it loose by using the XR hooklift equipment.
Use, for example, a forklift truck.
