tions will apply.
DEL Equipment (UK) Ltd (herein referred to as DEL) withhold the right to revise these
terms and conditions without prior notice at any time in the future.
General Terms and Conditions
1.1 DEL warrants its Customer and/or End User of its products, provided it has re-
ceived payment in full for the goods, that it will repair/replace, either in its factory or
through one of its approved Service Agents, without charge, any original part of any
DEL product found to be faulty within twelve months of installation or within fifteen
months after the date of despatch from its factory, whichever is the shortest, which is
proven to the satisfaction of DEL to be defective.
1.2 Warranty covers failure of DEL products and does not include installation (unless

2. OPERATING SYSTEMS
The tailift is powered from the vehicle battery. A wire is taken from the battery positive to
the powerpack starter switch and the hand control. These circuits are protected by in-line
fuses. The power to the hand control is isolated by a switch in the driver’s cab. When the
isolation switch is switched on, the up button on the hand control provides power to the
starter switch, which operates the powerpack motor. This pumps high-pressure hydraulic
fluid to extend the ram. On release of the up button the fluid is held in the ram due to a non
return valve which locks the ram in position therefore holding the platform stationary. Push-
ing the down button powers the lowering solenoid, which allows the hydraulic fluid back
from the ram to the power pack reservoir. The ram is connected to the powerpack with two
pipes, one is the high pressure feed hose the other is the low pressure return hose to the
reservoir. The ram pushes two chains, which, via a sprocket system, are connected to the
sliders at each side of the platform, which run inside the lift columns. When the down but-
ton is pressed the platform lowers by gravity. Each slider has a load safety device, which,
in the unlikely event of a chain break, jams the slider in its column. The opening and clos-
ing of the platform is torsion bar assisted. The torsion bar is pre-set on manufacture and
located inside the platform and is not a user serviceable part. The platform is stowed verti-
cally when not in use and is held in place by the platform locks. Care must be taken when
stowing the platform that the locks are correctly engaged and the stow indicator (if fitted) in
the drivers cab is off.

Del Equipment (UK) Ltd Operator/Maintenance Manual - Column Tailifts
3. SAFETY FEATURES
Before operating the tailift be sure you understand the safety devices fitted, and ensure
that they are in good working order by following the regular maintenance program.
CIRCUIT BREAKERS
Fuses protect the electrical circuits. In the case of any electrical fault they will protect the
tailift from any damage to its electrical systems. It is possible to disconnect the electrical
supply by removing the fuse.
ISOLATION SWITCH
The isolation switch located in the drivers cab ensures that the lift cannot be operated
whilst the vehicle is moving or whilst it is left unattended. The lift must ALWAYS be isolat-
ed after use.
LIFTING LOADS – RELIEF VALVE
The power pack is equipped with a pressure relief valve, which ensures that a gross over-
load of the lift, which may damage critical parts cannot be lifted. This valve is set on in-
stallation to ensure that the lift cannot raise a load 25% more than the safe working load.
LOWERING LOADS – FLOW REGULATOR
The returning oil from the ram passes through a flow regulator valve, ensuring the plat-
form lowers at a controlled speed irrespective of the load.
Note – The platform must not be overloaded on lowering, as this will cause permanent
damage to the lift operation.
LOAD SAFETY DEVICE (LSD)
Each slider has its own LSD located inside the column. In the unlikely event of a chain
failure the LSD will activate, jamming the slider in the column. The lift will not drop more
than 100mm from its position at the time of failure.
3 WAY FOLDING RAMP/CART STOP
On platforms equipped with a 3 way folding ramp, the edge of the ramp can be fixed in a
vertical position to ensure that loads cannot roll/fall from the loading edge of the platform
whilst lifting or lowering. A platform fitted with ‘cart stops’ has a similar effect.
CONTROL BOXES
The buttons are designed so they are just large enough to be operated by one finger. This
prevents accidental operation by other objects hitting the control box. The control boxes
themselves are mounted in a steel protective cover.
TOE GUARD
The toe guard is angled in such a way so to reduce the risk of feet being crushed while
the lift is being raised.
PLATFORM
The platform has a rough, anti-skid surface, which ensures that the platform is not slip-
pery in most weather conditions.
STOW INDICATOR (IF FITTED)
The stow indicator in the drivers cab activates when the platform is not in its stowed posi-
tion. Ensure that it is not active before driving the vehicle. If it activates whilst driving, stop
as soon as possible and check that the platform is stowed correctly.
HANDRAILS (IF PROVIDED)
Handrails are fitted wherever there is a risk of falling more than 2 meters.

5. INTENDED AND UNSAFE USES
INTENDED USES
The Column Lifts are intended for: -
 Lifting of loads vertically from the ground to vehicle bed height and vice-versa.
 Lifting of the load and the operator only, where the operator has been trained to
use the lift following all safety procedures.
 Lifting and lowering of loads no heavier than the safe working load of the lift fitted.
 DO/DT type lifts are to be used on tipping vehicles and form the vehicle tailgate.
UNSAFE USES
The following are un- safe practices, which may damage the lift and cause
risk of personnel injury: -
 Driving a forklift onto the platform.
 Using the lift as a jack.
 Using the lift as a link bridge.
 Using the platform as a step to the truck bed.
 Lifting unstable/wheeled loads without special precautions
 Use as a passenger lift
 Driving the vehicle with the platform open.
 Overloading the platform when loading from the vehicle to the platform.
6. SAFETY PROCEDURE
Before operating the lift be sure to understand the following instructions: -
1. Read and be familiar with the safety instructions and warning decals before oper-
ating the lift.
2. Be sure the vehicle is on level ground, securely braked and that there is adequate
lighting in the working area.
3. Inspect the lift for maintenance or damage. If there are any signs of damage do
not use the lift or attempt repairs unless you have been specifically trained.
4. Clear the working area of any obstructions.
5. Do not overload the lift. Note that the safe working load of the lift applies to both
lifting and lowering operations.
6. Make sure the centre of the load is placed as near to the centre of the platform as
possible. If wheeled loads are lifted ensure these are securely braked and that
available safety devices are used (3 way folding ramp/cart stop)
7. Make sure that whenever you intend to ride the platform that you leave enough
room to stand without risk of falling.
8. Make sure the platform is securely stowed in its travelling locks and that the stow
indicator (if fitted) is out before driving the vehicle
