SAFETY DEVICES
DHOLLANDIA tail lifts are equipped with a multiple safety devices in order to ensure that goods can be loaded and unloaded with
maximum safety for the operator, any potential bystanders, and the load itself. The following safety devices are incorporated or
recommended on most tail lifts:
•
Electrical safety valves mounted on all cylinders
[standard]. The
safety valves lock the oil inside the hydraulic cylinders as long as they
are not energized via the electrical controls. The purpose is to secure the
platform in its travel while driving, or in any other fixed position, in case
of accidental failure of a hydraulic pipe (as soon as the electrical controls
are released).
DHOLLANDIA safety valves are equipped with a manual emergency
control, allowing the operator or repair agent to open the valvue manually
in case of electrical failure (see MAINTENANCE AND REPAIR
MANUAL).
•
Mechanical platform lock(s)
[optional]. DHOLLANDIA offers (a)
mechanical platform lock(s) as an option, to further secure the platform
in its travel position in case of accidental loss of hydraulic pressure.
The use of a platform lock is good and safe practice in general. Also,
depending on the vehicle pay-load and the type of tail lift, extra locks
might be compulsory to comply with the CE load containment regulations
EN12195 and EN12642 Code XL. Ask DHOLLANDIA for further advice.
•
Pressure relief valve
[standard]. Safety device integrated in the pump unit, enabling the manufacturer and the installer of the tail
lift to limit the real lift capacity to the maximum rated capacity of the tail lift sold, and to protect it against overload while LIFTING.
•
Pressure compensated flow valves
[standard]. Flow valves are integrated in the hydraulic circuits to ensure the platform lowers
at a safe speed, both when empty as when fully loaded.
•
Marking of the centre point of maximum load
[standard]. Tail lifts
are not designed to LIFT and LOWER weights corresponding to their
maximum rated capacity over the entire surface of the platform. The
maximum rated capacity is only valid at a specified distance or “centre
point of maximum load” behind the vehicle body. Behind that point
marked on the platform, the maximum safe working load diminishes
according to the load diagrams supplied with the tail lift. See also

on load charts and
correct loading procedures.
•
2-hand exterior control box [standard]. On the exterior control box
mounted in fixed position at the side of the vehicle body, all functions
are actuated by means of a control switch and a safety switch. The
compulsory use of the 2 hands to actuate the various lift functions,
protects the operator from crushing his head, limbs or upper body
between the LIFTING or CLOSING platform and the rear frame of the
vehicle body.
