2.1 Applicable Standards and Directives
The lift has been designed in accordance with the applicable standards and
regulations. The most important of these are:
•
2006/42/EC Machinery Directive
•
2014/30/EU Electromagnetic Compatibility Directive
•
2014/35/EU Low Voltage Directive
•
DIN EN 1493:2011 Vehicle Lifts
•
DIN EN 60204-1-100:2019 Electrical equipment of machines - General requi-
rements
•
DIN EN ISO 13849-1:2016 Safety-related parts of control systems - General
principles for design
2.2 Service Life
The lift is designed and tested according to DIN EN 1493. The assumptions
therein are valid for 22,000 full load cycles. After reaching this number of cycles,
or after a maximum of 10 years, the lift must be replaced by a new product or
be given a general overhaul.
A general overhaul should only be carried out by the manufacturer or persons
authorized by them. Load-bearing structures must be inspected and, if
necessary, other parts must be replaced according to the manufacturer's
specifications.
2.3 General Machine Description
2.3.1 Design and Basic Functions
The lift consists of lifting units with flat head supports or swing arm supports.
The lifting units are hydraulically operated and mechanically interconnected.
The lifting units are mounted in concreted installation boxes or installation
frames. The hydraulic unit is suspended in the installation box or in the
installation frame, or stands on the floor away from the lift.
The lift is operated via the control element of the control box. Lifting and
lowering of the lift is performed via pushbuttons. The cable routing from the
control box to the lift is underfloor.
Lifting unit
The lifting units consist of a left and a right version. These are of mirror-image
and redundant design and are connected via a mechanical synchronous
connection. The lifting units are welded together from the two components
cylinder head and tank tube. Depending on the version, the cylinder head is
screwed to the installation box or the installation frame or clamped via
clamping elements. The cylinder head thus transfers the load from the vehicle
