Electrical vehicle interface

1. Design criteria for generator, battery, cables, fuses
For the proper functioning of the taillift, a reliable power supply is essential. The power of the taillift is usually provided by the vehicle battery or an additional battery, eg. for trailer. Vehicles on which taillift are mounted, typically have 12V or 24V battery systems. In the tables 1 and 2 in the annex recommendations for the battery capacity and current, as well as the necessary power generator, as a function of the weight classes for taillifts and vehicle voltage.

2. Electric preparation for taillift on trucks
Goal of the electric preparation is to offer a uniform electrical standard, or interface, so that all taillifts of the VDHH members can be directly connected. The preparation in the truck refers to the switch of the taillift in the driver cabin, the display of the operating or driving position of the platform and the starter lock and control electricity. The preparation package includes the Code A "control feed" and in anticipation of future developments, the code B and C "main feed". This electrical preparation ends truck-side with electrical plug-in connectors that are easy in the taillift-side opposing couplings have to be inserted.
More information about installation are listed in the annex and in the following circuit diagrams (circuit diagrams electrical preparation).

3. Installation of non-OEM controls
Wireless remote controls are in taillifts state of the art and are more and more used. Taillift manufacturer that offer remote controls, secure with the CE mark and the declaration that they comply with the EC machinery directive. The wireless remote control is part of the machine and must fulfill all requirements of the directive. This is the basic requirement for safe operation of the tail lift with wireless remote control. The retrofitting of non-original remote controls is not recommended. Most of these remote controls do not fulfill the minimum requirements. The declaration of conformity loses its validity and the machine must not be used. If wireless remote controls will be retrofitted, the retroffiter has to check if this is technically and safely permitted. Only the manufacturer of taillifts with original remote control is a guarantee of the full security of the entire system during operation.

4. SmartCharge
The operation of tail lifts at semi-trailer or trailer requires a reliable power supply. The electronically controlled charging system SmartCharge always guarantees operational reliability. The standardized plug connection, train and trailer vehicles with SmartCharge can be changed arbitrarily. SmartCharge allows a demand-oriented charging of the batteries. Well-charged batteries are the basis for operational safety during taillifts of semi-trailer or trailer. The electronically controlled charging system limits the charging current briefly to 50 A, permanently at 30 A. A fuse failure due to overloading is excluded. Thanks to the optimal dimensioning of the components the wear of the electric motor and power relay is reduced. Any disturbance of SmartCharge is indicated by a flashing signal in the driver cabin and a coded signal to the electronics module. The waterproof sealed electronics module is located on the tractor. In addition to the energy transfer passes SmartCharge also the feedback signal indicating the driving position of the taillift in the driver cabin of articulated trucks both for the platform on the truck and also for the trailer. For further information please contact your preferred tail lift manufacturer.

5. Rear lights
The VDHH with its members has determines the space requirement for the kinematics for all taillifts, to define a standardized rear light. This standardized installation space has been communicated to the truck manufacturers who can now act accordingly, or can provide for intended installations of a taillift a suitable rear light as an option. In the space drawing (02294.000-3) the installation space for trucks is defined.
