General conditions

Product liability

In relation to product liability the current rules under Danish

law shall apply.

The Seller shall never be held liable for operating losses,

loss of earnings and other indirect losses.

Product liability insurance which includes cover against

injury and property damage has been taken out.

Any disputes between the parties shall be settled by the

Maritime and Commercial Court in Copenhagen (Sø- og

Handelsretten) in pursuance of Danish law

Installation in corrosive surroundings

Special guidelines must be observed when installing the

rail system around swimming pools, etc.

The surfaces of the brackets used, traverse travelling

trolleys, etc., must be painted. Hoists must be supplied

with a special surface treatment.

All fixing elements, nuts, washers, threaded rods, must be

acid-proof.

Acid-proof threaded rods and dual-component adhesive

must be used for installation in concrete, tiles, etc.

Through-going threaded rods or acid-proof screws must

be used for installation in wood.

Particular care should be taken to avoid damaging the

surface of painted components.

Washers made of synthetic material must be used in

between painted surfaces and nuts and ordinary washers.

Damaged paint must be repaired after installation, and

visible threaded rods, nuts, washers, etc., must be covered

with paint.

Hidden threaded rods, nuts, washers, and brackets in the

rail track must be treated with a silicone coating.

Wherever possible, nuts must be fitted with protective

caps.

There must be no swarf, dirt, or other impurities in the

rail system as they will accumulate moisture and lead to

corrosion.

Bearings in traverse travelling trolleys must be treated with

a silicone coating before installation.

Placing a new Hoist in an existing rail system.

Please notice, before placing a new hoist in an existing rail

system it must be ensured:

• The rated max. load of the rail system, must be equal or

higher than the max. load of the new hoist.

• If there is no max. load mentioned on the rail system, it

must then be checked according to the guideline in the

installation manual (distance between bracket according

to max. load).

• If the brackets are not visible, then a load test with 1,5 x

max. load of the hoist must be performed. The deflection of rails must not be higher than 1/200.

• If it is not possible to do any of the above mentioned,

please contact Guldmann or their representative.

• If the rail system can not be rated to the same max. load

as the hoist, then there must be installed extra brackets

according to the installation manual (distance between

bracket according to max. load).

Installing heavy duty rail systems

Bracket types must be chosen in accordance with the list

of components, certain types of bracket must not be used

in connection with these installations.

A heavy duty model traverse travelling trolley must be used

in connection with room-covering rail systems rated over

500 kg (1100 lbs).

The distance between brackets must be adapted

to the type of rail in question in accordance with the

instructions.

Two installation elements, a glue anchor or expansion bolts

must be used per bracket when installing the system in a

concrete ceiling or wall, in accordance with the instructions.

Ceilings and walls made of materials other than concrete

must be carefully inspected and tested for suitability.

Special care should be taken when testing at 1.5 x the

rated load.

Note! GH3 rails with charging liners must not be used in

corrosive or dusty surroundings (areas around swimming

pools and at riding schools).

Quality designation for bolts, etc.

A4/AISI 316 = acid-proof

A2/AISI 304/rustproof 18.8 = not acid-proof

Protection against electric shock

Electrical installations

These precautions apply to installations made in Denmark.

Protection against electric shock

Local requirements may differ.

Guldmann ceiling hoist and rail systems are manufactured

and installed in accordance with Medical Electrical

Equipment UL 60601-1.

Guldmann has a UL/DEMKO approval of its products

which confirms that they meet the requirements contained

in UL 60601-1.

This regulation defines how medical equipment must be

classified and also how it must be protected so that

danger of electric shock does not arise when handling

the products.

Guldmann ceiling hoist and related rail system are classified as equipment in Class I – High Voltage Regulation,

Medical Electrical Equipment, Chapter 14.

Regarding installation of Guldmann rail systems

in bathroom environments

Guldmann power supply (transformer) must not be installed and charging of hoist must not be carried out in Areas

0, 1 and 2. Power supply and charging area must be

located outside Area 2, but hoist and rails may be used

inside the area.

If e.g. cleaning by hosing, the power supply and charging

area must be located completely separate from the area in

which splashing with water may occur.

If the rail system is only installed in the bathroom and not in

other rooms outside the bathroom, the rails do not need

grounding.

Grounding must be done if the rails continue outside the

bathroom and the lower edge of the rail is less than 3.0

m/ 120” above the floor.

Reference is made to Fig. 701A – Area Division 0 to 3.

Installation of the rail system is carried out with safety

voltage – designated SELV. The safety transformer

with a nominal voltage of 24 V AC voltage.

In accordance with the High Voltage Regulation,

Chapter 701 – AREAS WITH BATHTUBS OR SHOWERS

Excepted are:

Single rails hanging higher than 2.25 m/90” above the floor

and not continuing into Area 0, 1 and 2.

For single rails the grounding may be located as required

either in the bathroom or in the adjacent room.

The parallel rails do not need to be grounded.

Chapter 701.4 Protection for safety reasons

When SELV is used (safety voltage), protection against

direct contact must be in place regardless of the size of

the voltage, i.e. to min IP2X.

The geometry of the live rails meet the requirements for

protection against contact.

Any special requirements carried out without the participation of Guldmann are the purchaser’s own risk.

Chapter 701.413.1.6 Additional equalizer

Note

Metallic pipes and ducts (Guldmann aluminium rails) which

are only found in these four areas and are not conductive

when in contact with earth or parts outside the areas do not

have to be connected to the equalizers.

Note

These rules have been issued by the Electricity Council

and form part of the High Voltage Regulation.

There may be special local requirements for the installation

of rail systems in medical treatment areas.
