DHOLLANDIA
6.3 IMPORTANT GUIDELINES
6.3.1 General
6.3.2 Risk assessment by the installer
•The DHOLLANDIA column lifts consist of a wide range of different executions and are offered with a multitude of options to adapt
the liftgate to the client’s specific needs. They are installed on a wide variety of different vehicles, often personalized by the body
builder. Moreover, they are being used for an endless array of vastly different applications often unknown to the manufacturer.
•It is therefore important that the installer conducts a comprehensive risk assessment to make sure the liftgate complies with the
applicable legislation and can be used safely. SECTION 7 of the operation manual gives a good overview of the applicable risks that
must be mitigated. DHOLLANDIA strongly recommends implying the client and his H&S management in the risk assessment process
to obtain best possible understanding of the application and work conditions.
•In K9 executions travelling above the vehicle floor, the user and occasional bystander is exposed to additional risks, and a thorough
risk assessment is required.
WARNING
•ALWAYS make sure that the lift columns are installed in accordance with the installation instructions of DHOLLANDIA.
•Pay special attention to the type of bolts, minimum quantity per side, minimum size and strength class, and the spread of the bolts
over the full surface of the columns. Fasten the bolts and nuts with the required torque, see 16.2 on page 43.
•Incorrect or negligent installation can cause the liftgate to fall off the vehicle chassis once the platform is loaded, and can put the
installers, the operators, and bystanders at great risk of bodily injury or death.
•In case of doubt, don’t continue, but contact your national DHOLLANDIA dealer for further advice.
WARNING
•DHOLLANDIA liftgates are installed on a wide variety of different vehicles and are being used for many different applications often
unknown to the manufacturer.
•To guarantee the safe use of the liftgate in all foreseeable circumstances, ALWAYS conduct a thorough risk analysis. SECTION
7 of the operation manual provides a comprehensive overview of the main risks potentially associated with the liftgate use.

14
DHOLLANDIA
7MOUNTING OF THE LIFT FRAME (PREMOUNTED PLATFORM)
7.1 HANDLING
•Unless ordered otherwise, the column lift is delivered fully premounted. It can be handled by
a hoist or forklift from the installation guide bracket between the 2 columns.
•When using a forklift, position the forks as wide as possible, and correctly centered on the
middle of the installation guide bracket. If positioned too narrow, or out of center, the column
liftgate could shift sideways and fall.
•Drive slowly and safely. Take extra care when driving on uneven terrain. ALWAYS make sure
the column lift cannot shift from its position and fall.
•ALWAYS make sure you keep the bottom of the columns at a safe distance from the ground.
ALWAYS make sure that the column lift cannot slide forwards off the forks and fall. Secure the
installation guide bracket by means of adequate clamps, or incline the mast of the forklift.
•Clamp 2 lengths of 3” (76 mm) minimum alignment tube channel or other sufficiently strong material, to the bed extension with
approx. 4” (100 mm) overhang. These alignment tubes will help align the platform with the bed extension.
•Install at minimum, a 300 lbs (136 kg) counterweight on the tube channels to prevent them from moving during installation. Or
tack-weld the tube channels temporarily to the rear sill and floor of the vehicle.
CAUTION
•The lift frame is heavy! When falling on a person it can cause serious personal injury or death.
•Therefore, handle the lift frame with extreme care. Use an adequate gantry crane, hoists, or a forklift to move the lift frame safely,
without a risk of collapse.

15
DHOLLANDIA
•Bring the liftgate in front of the rear frame of the body. Observe the guidelines and precautions for handling.
•Raise the liftgate to the correct mounting height and align the cylinder beam with the 2 alignment tubes positioned earlier at the
rear sill.
•Ensure the lift columns are square by checking the
diagonals between the columns as shown. The distances
between the tops and bottoms of the columns should be
equal.
•Ensure the cylinder beam is parallel and even with the vehicle
floor using the alignment tubes. Center the cylinder beam to
the vehicle body.
•Ensure both lift columns are perpendicular
to the ground.
•If the lift columns are not perpendicular to
the ground, adjust by adding shims starting
at the top side of the lift columns.
•After installation, the platform will deploy at
90* from the lift columns.
•The platform is designed to be level with the
ground, and not the vehicle floor.

16
DHOLLANDIA
7.2 WELDED INSTALLATION
NOTICE
CAUTION
•If you intend to weld, ALWAYS follow the NOTICE and CAUTION with regards to welding in section 4 on page 6.
NOTICE
•Besides the physical protection of hydraulic hoses and composite parts, be aware that the lift runners inside the columns are
equipped with nylon slide pads.
•The heat generated by welding can melt or deform the nylon slide pads. Hot metal chips, welding sparks and slag falling inside
the lift columns can damage the nylon pads, the lift runners, and the chain break protection devices.
•ALWAYS LOWER or LIFT the lift runners and the nylon slide pads as far away as possible from the area to be welded.
•ALWAYS use a welding blanket to prevent hot metal chips, welding sparks and slag from falling inside the columns. Clean out the
columns if required.
•The installer or body builder must make sure that the rear frame of the body is sufficiently strong to sustain the forces exerted by the
column lift and its load at the maximum rated capacity, plus legally mandated safety factors.
•ALWAYS grind off the galvanization or paint from the areas to weld.
•The cylinder beam must be strongly connected to the rear cross member of the vehicle floor. Once in use, this connection will prevent
the cylinder beam from bowing down when heavy loads are transferred from the platform to the vehicle floor or vice versa.
•For column lifts with an aluminum cylinder beam, follow the bolt instructions in 7.3 from page 19 onwards. (unless the rear sill of the
loading floor is aluminum too, and both can be welded together).
•Push the columns and the cylinder beam hard against the rear frame of the body (and shims if necessary).
•Make sure the cylinder beam is level and parallel with the rear sill of the vehicle floor.
•Make sure that the lift frame and cylinder beam are properly centered, square, plumb, level, and true to the vehicle body.
•Use suitable C-clamps to secure the lift columns and cylinder beam in the final working position.

17
DHOLLANDIA
•Make 2 light welds at the top of
the columns to attach the lift
frame to the rear frame of the
body.
•Do NOT weld further at this
stage, to avoid damage to the
nylon slide pads.
•Make the welds or connection
between the cylinder beam and
the rear sill of the loading floor,
in accordance with the
instructional graphic on page
18.
•Temporarily connect the battery and ground
cables of the liftgate to the vehicle batteries or
an auxiliary battery cart (see 10.1 on page
27).
•(1) Operate LOWER to release the platform
from the up stop lock.
•(2) For manual closure platforms, release the
platform latch by sliding the latch upwards
(located towards the inboard edge of the
platform).
•(3) OPEN the platform.
•(4) LOWER the platform fully to the ground to
create maximum possible distance between
the slide pads and the area to weld.
•On hydraulic open gates, remove the tilt cylinder hose guard and protect the hydraulic hoses with a welding blanket before
welding.
•Weld the lift columns to the rear frame of the body in accordance with 7.2 on page 18. Also finalize the 2 top welds applied to attach
the lift frame to the rear frame.
•Clean up the welds, remove any burnt galvanization or paint and apply adequate anti-corrosion protection.
•Verify that all nylon slide pads have remained undamaged. Replace them if required. See contact info on page 4.
•Verify that no metal chips, welding spares and slag have fallen inside the columns or cylinder beam. Clean out if required

18
DHOLLANDIA
WARNING
•Position the liftgate, cylinder beam, and lift columns in accordance with the instructions in this manual.
•Weld the lift columns to the rear frame of the vehicle body in accordance with all welding instructions in this manual.
•Disregard could lead to a fall of the liftgate and its load, and may put the operator and bystanders at risk of serious personal injury
or death.

DHOLLANDIA
7.3 BOLT-ON INSTALLATION
7.3.1 Position of the drill holes
•The drill-hole template starts at a fixed distance below
the vehicle floor. From that point onwards, the spacing
goes up in fixed steps, and it goes down a fixed amount
depending on the liftgate order.
•The center width of the drill-holes will be determined by
the vehicle width. The mcw can be measured before
installation –do so at the holes positioned just below the
top of the liftgate cylinder beam.
•To easily find drill hole positioning, the liftgate can be
brought up to the rear of the vehicle body as described
in 7.1 from page 14 onwards. The topmost holes may be
manually marked through the column using a paint or
marker.
•Mark the center points of the drill holes on the rear frame
of the body.
•Drill the holes through the rear frame of the body.
•Deburr and apply adequate anti-corrosion protection.
7.3.2 Mounting of the lift frame
•The installer or body builder must make sure that the drill holes in the
rear frame are sufficiently strong to sustain above mentioned forces,
plus legally mandated safety factors, and the bolts won’t be pulled out
of the rear frame. Use reinforcement strips or big washers to spread the
forces over a larger surface.
•Additional bolts must be foreseen in the cylinder beam and through the
rear sill of the vehicle floor. Once in use, this connection will prevent the
cylinder beam from bowing down when heavy loads are transferred
from the platform to the vehicle floor or vice versa.
•Push the columns and the cylinder beam hard against the rear frame of the body.
