To follow the minimum finished dimensions, make sure to consider the tolerances according to VOB, part C (DIN 18330 and 18331) and the DIN 18202. 3 Car width for platform width 230 cm [7’-7’’]. If wider platforms are used it is also possible to park wider cars. 4 For dividing walls: cutting through 10 x 10 cm [4’’ x 4’’]. 5 Potential equalization from foundation grounding connection to system (provided by the customer). 6 Slope with drainage channel and sump.

Biggest type
Three-sided barrier compliant to DIN EN ISO 13857. In compliance with DIN EN 14010, 10 cm [4’’] wide yellow-black markings compliant to ISO 3864 must be applied by the customer to the edge of the pit in the entry area to mark the danger zone (see „load plan“ page 5). 9 At the transition section between pit floor and walls no hollow mouldings/coves are possible. If hollow mouldings/coves are required, the systems must be designed smaller or the pits accordingly wider. 10 For convenient use of your parking space and due to the fact that the cars keep becoming longer we recommend a pit length of 540 cm [17’-9’’]. 7 8

Carriageway in accordance with local regulations
For parking boxes on the edges and boxes with intermediate walls we recommend our maximum platform width of 270 cm [8’-10’’] for single platforms and 540 cm [17’-9’’] for double platforms. Problems may occur if smaller platform widths are used (depending on car type, access and individual driving behaviour and capability).
For larger limousines and SUV wider driveways are necessary (in particular on the boxes on the sides due to the missing manoeuvring radius).

Operating device
By default, the system can only be used for a fixed number of users. If different users use the system – only on the upper parking spaces – (e.g. short-time parkers in office buildings or hotels) the Multiparking system needs to be adjusted. If required, would you please contact us.
The home and off position of the system must always be in the lowered position. Special controls with key interlock are required that ensure that the key can only be removed when the system has been lowered to its lowest position. Depending on the conditions of the construction project, a stand may be necessary for the control elements (at an extra charge).
Low-noise power units mounted to rubber-bonded-to metal mountings are installed. Nevertheless we recommend that parking system’s garage be built separately from the dwelling. If it is not possible to install the hydraulic power units with the solenoid valves in adjacent buildings or spaces, the power unit and the solenoid valves must be housed in a cabinet (at an extra charge).
– wall recess plans – maintenance offer/contract – declaration of conformity – test sheet on airborne and slid-borne sound
Units
Building application documents
According to LBO and GaVo (garage regulations) the Multiparking systems are subject to approval. We will provide the required building application documents. Gap covers
Any existing gaps between the systems or the platforms and the walls of the pit must be reduced to approx. 10 cm by installing sheet-metal covers (at an extra charge). Environmental conditions
Environmental conditions for the area of multiparking systems: Temperature range –20 to +40° C [–4 to +104° F]. Relative humidity 50% at a maximum outside temperature of +40° C [+104° F]. If lifting or lowering times are specified, they refer to an environmental temperature of +10° C [+50° F] and with the system set up directly next to the hydraulic unit. At lower temperatures or with longer hydraulic lines, these times increase. Sound insulation
As per DIN 4109-1 (sound insulation in building construction), Section 9, KLAUS Multiparker are in the range of technical domestic installations (garage systems). Normal sound insulation:
DIN 4109-1, Section 9, maximum permissible A-rated sound levels in rooms requiring external protection, generated by technical domestic installations and commercial businesses affiliated with the building.
Table 9 shows the values for the maximum permissible A-rated sound levels in rooms requiring external protection, generated by technical domestic installations and business affiliated with the building. As per line 2, the maximum sound level in living rooms and bedrooms must not exceed 30 dB (A). User noises are not subject to the requirements (DIN 4109-1, Section 9).
The following measures are required to comply with this value: – Sound protection package according to offer/order (KLAUS Multiparking GmbH) – Minimum sound insulation of the building of min. R’w = 57 dB (service/item to be provided by the customer) Increased sound insulation (special agreement):
VDI 4100 (sound insulation in building construction) Assessment and proposals for enhanced sound insulation. Agreement: Maximum sound level in living rooms and bedrooms 25 dB (A). User noises are not subject to the requirements (see VDI 4100, Paragraph 1, Scope of application – Notes).
The following measures are required to comply with this value: – Sound protection package according to offer/order (KLAUS Multiparking GmbH) – Minimum sound insulation of the building of min. R’w = 62 dB (service/item to be provided by the customer) Note: User noises are basically noises that can be individually influenced by the user of our Multiparking systems. These include, for example, driving on the platform, slamming vehicle doors, engine and brake noises.

Care
To avoid damages resulting from corrosion, make sure to follow our cleaning and care instructions and to provide good ventilation of your garage. Corrosion protection
See separate sheet regarding corrosion protection. CE Certification
The systems on offer comply with DIN EN 14010 and EC Machine Directive 2006/42/EC. Furthermore, this system underwent voluntary conformity testing by TÜV SÜD.

Marking
Constraints according to DIN EN ISO 13857 must be put in place on three sides (all except the entrance side), unless buildings border the pit.
In compliance with DIN EN 14010, 10 cm [4’’] wide yellow-black markings compliant to ISO 3864 must be applied by the customer to the edge of the pit in the entry area to mark the danger zone.
Consecutive numbering of parking spaces.
Any necessary wall cuttings according to page 1.
Any required lighting, ventilation, fire extinguishing and fire alarm systems as well as clarification and compliance with the relevant regulatory requirements.
Suitable electrical supply to the main switch must be provided by the customer during installation. The functionality can be monitored on site by our fitters together with the electrician. If this cannot be done during installation for some reason for which the customer is responsible, the customer must commission an electrician at their own expense and risk. In accordance with DIN EN 60204 (Safety of Machinery. Electrical Equipment), grounding of the steel structure is necessary, provided by the customer (distance between grounding max. 10 m).
Numbering of parking spaces Building services
Drainage
For the front area of the pit we recommend a drainage channel, which you connect to a floor drain system or sump (50 x 50 x 20 cm). The drainage channel may be inclined to the side, however not the pit floor itself (longitudinal incline is available). For reasons of environmental protection we recommend to paint the pit floor, and to provide oil and petrol separators in the connections to the public sewage network. Strip footings
If due to structural conditions strip footings must be effected, the customer shall provide an accessible platform reaching to the top of the said strip footings to enable and facilitate the mounting work.
Wall cuttings
Electrical supply to the main switch / Foundation earth connector
If the following are not included in the quotation, they will also have to be provided / paid for by the customer:
– Mounting of contactor and terminal box to the wall valve, complete wiring of all elements in accordance with the circuit diagram – Costs for final technical approval by an authorized body – Main switch – Control line from main switch to hydraulic unit
Description Single platform (EB) and Double platform (DB) General description
