1. Principles for designing a cableway

The wakeboard/water ski cableway can be installed on lakes, rivers and on the sea with 4, 5 or

6 masts. The basic structure of the cableway is limited by this geometry, by the need for safety

distances and by the required or maximum water depths. Any deviations must be reported to

Rixen Cableways GmbH.

Segments of a wakeboard/water ski cableway:

A segment is defined as the distance between the individual masts

Maximum length of a segment: 310 m

Minimum length of a segment: 25 m

Recommended minimum starting segment: 70 m

Recommended minimum length in front of the motor mast: 45 m

Running angle of a wakeboard/water ski cableway:

The running cable angle is defined as the internal angle of the running cable on the mast

Maximum angle on a mast: 130°

Minimum angle on a mast: 85°

Recommended angle on the masts: 90°-120°

Safety distances:

The safety distance is defined as the right-angled distance between the running cable and the

shore, an island or any other obstacle. In the case of varying water depths, the minimum water

depth must be used as the basis.

Safety distance with standard tow rope length: 26 m

With other tow rope lengths: Lt + 7 m

Dachau, 15.05.2012


Water depths:

The minimum water depth is defined as the depth at the described point at low water

Minimum water depth below the running cable and at

a distance of 15 m to the left and right of the running cable: 1 m

Minimum water depth at the start ramp: 1.5 m

Minimum water depth near obstacles: 2 m

Maximum water depth near the masts: 22 m

If the water depth near the masts is more than 5 m, the customer must provide divers for the

installation.

Safety distance between carriers:

Minimum safety distance between carriers: 70 m (at 30 km/h)

If the cableway is operated faster than 30 km/h, only every 2nd carrier should be used.

Other geographical and geological data:

Wind load for the calculations:

(Rixen Cableways GmbH must be notified if the wind load is

higher)

0.65 kN/ m² up to a height of

10m

0.8 kN/m² above 10m

Minimum soil pressure around the base plate: 200 kN/m²

Soil coefficient of static friction (concrete to subsoil)

With land anchors: 0.6

With water anchors: 0.35

Evidence of the soil pressure and soil coefficient of static friction must be provided to Rixen

Cableways GmbH before installation. If anchors slide during installation due to unproven or

incorrect values, the costs resulting from this shall be paid by the contractual partner of the

installation. Rixen Cableways will not accept the risk of the coefficient of static friction values.

Dachau, 15.05.2012


2. Official approvals

Depending on the country, various approvals are required to install and operate a

wakeboard/water ski cableway. Rixen Cableways GmbH can act only as an advisory and

supporting partner in this respect. The contractual partner must ensure that all the necessary

approvals are obtained before the construction and operation of the cableway commences.

Rixen Cableways GmbH will provide the following documents:

a) Layout of the cableway including the necessary safety distances and water depths

b) Station plans for all masts including dimensions of the individual masts and anchor

foundations

c) Standard drawings including a reinforcement plan for the anchor foundations

d) Data sheet for the tensioning weight

e) Standard dimensional drawing for the start ramp

f) Certificate of the load bearing capacity of the cableway (maximum calculation)

g) Force calculation for the cableway

Dachau, 15.05.2012


3. Surveying the site

Before the foundations and the start ramp are constructed, the site must be surveyed. The most

practical solution is to have it surveyed by a local surveyor and a Rixen employee.

Any survey plan should be compiled in AutoCAD formats dxf or dwg.

The survey plan must contain the following details:

a) Water depth when the survey was carried out and potential deviations

b) Position, height and alignment of all foundations

c) Position and height of the mast base plates

d) Position and height of the start ramp at a minimum of 6 points

e) Water depth near the safety distances

f) Position of the electrical control system for the cableway

Any changes in the site plan may only be carried out by mutual agreement between Rixen

Cableways GmbH and the contractual partner.

If changes are made to the start ramp or to the layout of the lake without the agreement of

Rixen Cableways GmbH, the contractual partner shall be responsible for any additional costs

incurred due to this.

Dachau, 15.05.2012


4. Foundations and tensioning weight

Rixen Cableways GmbH calculates and defines the position and size of the foundations based

on local conditions. The foundations are usually the responsibility of the contractual partner.

Anchor foundations:

Usually, 2 concrete foundations on the shore or under water are used to tension the masts. The

size of the anchor foundations can be found in the station plans for the masts and in the force

calculation. The standard drawings specify the reinforcement and the tie bars depending on the

type of anchor.

Building materials to be used:

Concrete: See concrete description below

Steel for tie bars: S 235 JR G2 (RST 37-2)

Reinforcing steel: Q 188 A / Q 355 A

We recommend that the tie bars be galvanised. It is specified that the tie bars must be painted

with a rust protection agent. The tie bars must be freely accessible in the direction of the top of

the mast. Delivery documents and photos of the anchors must be provided to the testing bodies

as evidence that the correct building materials were used.

Tensioning weight:

The size and design can be found on the tensioning weight data sheet for the cableway.

Building materials to be used:

Concrete See concrete description below

Steel for tie bars S 235 JR G2 (RST 37-2)

Reinforcing steel Q 188 A

We recommend that the tie bars be galvanised. It is specified that the tie bars must be painted

with a rust protection agent. A weight slip must be provided to the testing bodies as evidence of

the weight.

Concrete

Anchor foundations and tension weights are exposed to different forces and environmental

stresses. Therefore you have to check beforehand which concrete you have to use for

cableway.

This table should assist you to find the right concrete.

Sourrounding conditions Classifcation -

Dachau, 15.05.2012


5. Electrical system

The manufacturer will supply the control system for the cableway and the cable from the control

cabinet to the operation platform and to the motor mast. A local electrician must connect the

system and install the cables. Control and power cables should be installed in separate cable

ducts (provided by the contractual partner) and, if possible, with a gap of at least 50 cm between

them. The cable ducts should have a cross section of >= 50 mm and be UV-stable. On

completion, the electrician must compile a test log for the system. Rixen Cableways GmbH

employees can provide assistance as regards the connection.

Standard connection:

Power: 32kW - 45 kW depending on the

number of carriers

Voltage: 400 V (three-phase current)

Cable: 3 x 35mm² + N + PE

Current and preliminary fuse: 125 A current with 100 A fuse

RCCB with ID No.: 300 mA

Other connected loads must be specified separately and be defined in the agreement.

Cable ducts must be approved for outdoor use.

The control cabinet should be installed in a cool, dry room. In very hot countries we recommend

the installation of an air conditioning system. The room temperature must be between -5°C and

+30°C. The distance from the control cabinet to the motor mast and to the operating platform

may not exceed 80 m.

Dachau, 15.05.2012


6. Delivery

Damage caused by delay due to a late delivery will not be acknowledged.

The buyer shall be responsible for all standing and waiting times of trucks and/or containers due

to customs formalities and has to take over the arisen costs.

Dachau, 15.05.2012


7. Installation

Depending on the scope of delivery and the degree of difficulty, it takes between 4 and 6 weeks

to install a cableway.

The following conditions must be adhered to:

a) Before installation begins, all anchor foundations and the tensioning weight must be

completed and the documentation for this work (photos) must be sent to Rixen

Cableways GmbH.

b) The start ramp and the main power connection must be completed at the latest in the 2nd

week of installation.

c) The contractual partner must provide two workers during the entire installation and initial

training times.

d) The contractual partner must take out building site insurance against fire, theft and

vandalism.

e) The contractual partner must take suitable measures to secure the building site against

theft and vandalism.

f) During the installation the contractual partner must provide a boat with outboard motor

(min. 5 HP)

g) The contractual partner has to provide a telescopic forklift (see chapter delivery)

h) If the required load bearing capacity data for the feet of the mast (see page 3) is not

available, the contractual partner must take suitable measures (e.g. tipping gravel etc.).

The pre-assembly information document contains more details.

Dachau, 15.05.2012


8. Acceptance

When the installation and initial training have been completed, the contractual partner must

accept the cableway. This is done in writing using the acceptance log that is part of the delivery.

The following points must especially be defined in the acceptance log:

a) Condition of the cableway upon acceptance

b) Damaged or missing parts on the cableway, spare parts or other contractually agreed

additional deliveries

c) Additional work by the contractual partner or Rixen Cableways GmbH not included in the

contractual agreement

d) Additional costs on the part of the contractual partner or Rixen Cableways GmbH not

included in the contractual agreement

The acceptance log document contains more details.

Dachau, 15.05.2012


9. Repair and maintenance

During the installation and initial training the workers provided by the contractual partner will be

shown all the basic maintenance and repair work. The contractual partner also receives a

technical operation manual that explains all the maintenance and repair work. We urgently

recommend that the contractual partner keeps an operation journal to log all maintenance work.

Rixen Cableways GmbH will accept no liability for damage resulting from a lack of or from

incorrect maintenance.

Changes in the angle of the masts

In the first months after the cableway has been installed, the angle of the masts may change

slightly due to soil compression. The contractual partner must control this and, if necessary,

adjust the masts according to the operating manual and the instructions.
