§1 - Introduction
• This manual forms a quick guide for the use of the lift model DH-VO.07.K1 or DH-VO.15.K1 with option OVU010 DUMP-
THROUGH.
• This manual handles with the particular user and safety instructions involved in working with a DUMP-THROUGH lift. It
must be read in conjunction with the general user’s manual with regards to the safety instructions for the operator
(chapter A), the periodic maintenance (chapter B), and the legal requirements regarding period testing and certification
(chapter C).
• In case of doubt, stopimmediately, and ask further advice from DHOLLANDIA prior tocontinuing.
§2 - Electrical controls
• The lift can be operated by a variety of electrical controls, which fall outside of the scope of this supplement
manual. For further information, please refer to the general user’s manual issued with the lift.
• Where operations involve an electrical control, the functions will be shown as shown on right side
Consult the user’s manual before getting started. Follow all safety instructions. Check if the lift can be used safely, and that no urgent
maintenance or repair is required. DO NOT continue if any unsafe condition exists
§3 - General outline
• DUMP-THROUGH OVU010 column lifts are designed to be mounted at the rear of tipper bodies, and can be used in 2 different
ways
1. CASE1: From the closed road-position behind the vehicle body, the platform can be unlocked at the top of the lift runner, and
deployed to serve as normal tail lift, to load and unload goods from the ground to the vehicle floor (and vice versa)
2. CASE 2: From the closed road-position behind the vehicle body, the platform can be unlocked at the bottom of the lift runner,
and transformed into top-hinged rear door, so that loose goods (sand, gravel,…) loaded onto the truck bed can be dumped
through and between the lift platform and the rear of the vehicle floor.

N° Opening the platform
1 Consult the user’s manual before getting started. Observe all safety instructions.
2 Switch on the electrical power to the tail lift (cabin switch in the driver’s cabin, and battery switch of the exterior control box).
3 Ensure that the 2 top pivot pins L+R and the 2 bottom articulation pins L+R are fully engaged and locked before commencing.
See Fig. 4.3 below.
If applicable, LOWER the mechanical or hydraulic stabilising legs into work position.
4 LOWER the platform approx. 20cm to a height that brings the 2 top pivot pins L+R within your reach.
5 Whilst standing beside the platform (not under !), release the security needles locking the 2 top pivot pints L+R. See Fig. 4.3.
6 Manually open the platform 90° into horizontal work position. For platforms with torsion bars fitted, ensure the platform is locked
in horizontal position.
N° Loading & unloading
Select between exterior control box and auxiliary controls.
7 Use any of the functions LOWER (see generaluser’s manual) to LOWER the platform to the ground.
7 Use any of the functions LIFT (see general user’s manual) to LIFT the platform to the vehicle floor level.
8 Observe the loading diagrams & instructions at all times.
N° Closing up in travel position
9 LIFT the platform up to a convenient height for closing.
10 Stand to the side of the platform, press it down by hand, disengage the open-platform-lock, and manually close the platform into
vertical travel position.
11 Mount the security needle in position, secure the 2 top pivot pins L+R. See Fig. 4.4.
12 LIFT the platform until the mechanical travel lock is engaged.
If applicable, LIFT the mechanical or hydraulic stabilising legs into travel position.
When using the lift platform as proper tail lift, to load and
unload goods, it is important that rod extensions of the
bottom L+R articulation pins are securely locked and
fastened in the locking device mounted on the lift runner.

§5 - CASE 2: Top-hinged rear door allowing to dump-through.
• The instructions in this § explain the procedures to demount the bottom articulation pins from the platform, and enable the platform
to tilt open when the tipping body is lifted in the air.
1- Verify and ensure that the security
needles on the 2 top pivot pins L+R are
fully engaged. Stow the platform in the
highest position.
2– Push the extension rod of the 2 bottom articulation pins (L+R) forwards. Take into
account that at least one of the pins is connected to the torsion bar inside the platform,
and that this rod will strongly pivot towards you as soon as the locking device (3) is
released.
3– While still pushing the extension rod forward, lift the locking device, so that the bottom
articulation pin with its extension rod can pivot rearwards.

Extension rod is under tension from
torsion bar inside platform, and will
forcefully pivot rearwards when releas-
ing the locking device (3). Beware of
hand or finger traps!
4- Pivot the bottom articulation pins (L+R) with their extension rod rearwards, releasing
them from any tension of the torsion bar(s) inside the platform.

5- Demount the bottom articulation pins on
L & R side.
6– The platform is now ready to pivot
around the 2 top pivot pins (L+R), and tilt
open when the tipping body is lifted.

• In order to stow the platform back in road position, proceed in inverse order. The bottom articulation pins that were under tension
upon their dismounting, should be mounted into the platform under the right angle, in order to fit over the square torsion bar inside
the platform, and result in the same tension as originally foreseen.
1– NOT OK, articulation pin mounted 45°
too low on the square torsion bar inside the
platform.
2– OK, articulation pin mounted correctly
on the square torsion bar inside the
platform.

3– Lift the locking device.
4– Push the extension rod of the 2 bottom
articulation pins (L+R) forwards. On the
pins mounted over the torsion bar, force
will be needed to overwin the tension of
the torsion bar.
Proceed with care, beware of hand and
finger traps. Beware that the torsion bars
incorporate a lot of energy, and might flip
back towards you when released before
the locking device is engaged !
6– Ensure that the extension rods of the
bottom articulation pins are correctly
secured.
Warning !
In order to avoid premature damage or wear to the platform, tip the vehicle body and
dump its load with care and consideration. Hard and brutal impact of solid objects
against the platform surface can cause damage. DHOLLANDIA cannot be held
liable for mechanical damage afflicted in this way to the lift.
