CAUTION
Welding on galvanized parts can produce hazardous fumes. To avoid intoxication:
ALWAYS wear a suitable respirator.
ALWAYS provide good ventilation.
ALWAYS grind off the galvanization from the areas to weld.
Most lifts are equipped with thermoplastic hoses, that can be damaged by hot metal chips, welding sparks and slag.
Damage to a hose can lead to sudden loss of hydraulic pressure and an accidental drop of the platform.
The penetration of welding sparks and slag can also cause a flame flash.
Both types of incidents can put the welder or installer and any bystanders at great risk of personal injury or death. To avoid
these risks:
ALWAYS protect and cover thermoplastic hoses with a welding blanket, prior to grinding, drilling and welding.
ALWAYS inspect the hydraulic hoses at the end of the installation process. Make sure all hoses are undamaged,
replace them if required.
Welding can cause severe damage to the electronic components of the vehicle and lift. To prevent damage:
ALWAYS follow the instructions and precautions of the vehicle manufacturer.
DO NOT weld if this is not authorized by the vehicle manufacturer.
ALWAYS disconnect the battery and ground terminals from the battery.
ALWAYS connect the ground directly to the component being welded, as close to the weld as possible.
Welding should be done by skilled and qualified tradesmen only.
NOTICE
Make sure the vehicle battery power is disconnected while installing the wheelchair lift. Connect the battery power to the
wheelchair lift only when the installation is completed or as required in the installation instructions.
DHOLLANDIA wheelchair lifts are designed as a bolt-on system and don’t require any welding. See section 9.2 for prescribed
torque values.
Welding should be done by qualified personnel only and only to the extent allowed by the vehicle manufacturer. Ensure that
the positive and ground cables are disconnected from the batteries and that all electrical and electronic equipment is fully
isolated before welding.
ALWAYS keep the ground clamp as close as possible to the weld location.

1.7 DESCRIPTION AND WHEELCHAIR LIFT TERMINOLOGY
1.7.1 General
DHOLLANDIA lifts are developed and manufactured using state-of-the-art technology, high quality materials and components,
and highly skilled workmanship. They comply with the European CE safety regulations mentioned in the Declaration of
Conformity issued with each lift (unless otherwise agreed for lifts exported outside the CE region).
The DH-CH003 and the DH-CH100... series comprise of a range of cassette lifts, designed for a wide range of multi passenger
vehicles, busses and coaches, with different mounting positions in or under the vehicle, but functioning in a very similar way.
In travel position, the platform and lift frame are safely stored inside a sealed “cassette”. Upon deployment, the platform and lift
frame are slid out of the cassette. Then a bridge plate and handrails are unfolded to make the lift ready for use.
This cassette can be mounted in various positions depending on the type of vehicle: under the chassis, in the luggage
compartment, or integrated in one of the access stairs of the bus.
Main details and terminology: see below.
DH-CH003* / CH101* / CH102* / CH103* ●TERMINOLOGY

Description
1
Cassette: sealed box housing the lift frame and platform when stowed in travel position, and protecting the mechanism
against adverse weather conditions.
The cassette is equipped with slide rails and a retraction system to slide the lift frame and the platform from a travel position
deep inside the cassette to a work position at the outboard edge of the cassette, and vice versa.
2
Mounting brackets: brackets used to mount the cassette to the vehicle.
3
Lift frame: steel assembly incorporating the lift arms and lift cylinders, who together carry the platform. The lift frame is
moved in and out of the cassette by means of an electric motor and gearwheel system.
4
Lift arms + lift cylinders: 2 lift arms L+R actuated by the lift cylinders, used to lift / lower the platform and its load (=
functions UP / DOWN).
5
Platform: carries the load during lifting / lowering. The platform is covered with an aluminium top plate with a non-slip
surface. It is further equipped with a bridge plate, handrails and a roll stop flap.
The platform can be 1 single section [# 5] or an extensible platform [# 6] with a platform main section [# 6a] and an extensible
point [# 6b].
6
Extensible platform: extensible platforms are used to shorten the mounting space needed to fit a cassette lift with a certain
platform depth. It is standard on lift type DH-CH003*.
6a
Platform main section: inboard main section of the extensible platform, attached to the lift arms.
6b
Extensible point: extensible point of the platform, pulled out upon deployment of the lift, and pushed back upon stowage.
7
Flashing platform lights: used to make the platform visible to other parties in traffic.
8
Bridge plate: plate mounted at the inboard platform edge, used to bridge any gap between the platform and the vehicle
floor when the platform is raised to its maximum height.
9
Handrails: Rails mounted at both sides of the platform. Lift occupants should hold on to these handrails to prevent them
from falling off the platform. Handrails must be deployed manually and secured in vertical position prior to using the lift, they
must be stowed manually before retracting the lift back into its travel position.
On DH-CH101*, foldable extensions [# 9a] to the handrails are available as an option (option OWP013).
10
Roll stop: roll stop mounted at the outboard platform edge. The roll stop is tilted up automatically when the platform leaves
the ground, it is tilted down automatically when the platform touches the ground.
The roll stop prevents the wheelchair from slowly and unexpectedly rolling off the platform during lifting and lowering. It is
not designed to stop fast and powered movements.
11
Automatic cassette lock: in regular conditions, the lift frame and platform are automatically locked inside the cassette by
