2. General safety regulations

2.1 Intended use The fixed ladder is intended solely for the following applications:

• Fixed installation on buildings, machinery, silos etc. as a means of access to the

respective units

• Assembly and use in accordance with the applicable standards DIN 18799-1

(for Austria: ÖN Z 1600), DIN 14094-1 or EN ISO 14122 Part 4

• Use of all accessory parts in accordance with this manual

2.2 Improper use Hazards may arise as a result of improper use. In particular, improper use includes

the following:

• Unauthorised structural modifications or incorrectly executed repairs

• Combination with components from other manufacturers in ladder and platform

systems

• Use of single parts or the overall system for purposes for which they were not

intended

• Use of parts other than those supplied or approved by Zarges

2.3 Safety equipment The following safety equipment (fall protection devices) is approved for use:

• Fall arrester system

• Back guard

Manipulation of the safety equipment is prohibited. If defects are ascertained, the fixed

ladder system must not be used.

Observe the relevant standards, depending on the designated use of the fixed ladder

system.

2.3.1 Fixed ladders for construction work (DIN 18799-1)

A fall protection device in the form of a back guard or a fall arrester system in

accordance with EN 353-1 is mandatory from a fall height of 5 metres onwards.

If the fixed ladder is of multi-section design, the maximum permissible length of each

ladder section is 10 metres.

2.3.2 Emergency-ladder systems (DIN 14094-1)

A fall protection device is mandatory from a fall height of 3 metres onwards. Fall arrester

systems in accordance with EN 353-1 must not be used. Only a fall protection device in the

form of a back guard is permissible.

If the fixed ladder is of multi-section design, the maximum permissible length of each

ladder section is 6 metres.

The top exit must be designed with an angled stile.

2.3.3 Permanent means of access to machinery; fixed ladders (EN ISO 14122 Part 4)

A fall protection device in the form of a back guard or fall arrester system in accordance

with EN 353-1 is mandatory from a fall height of 3 metres.

If the fixed ladder system is of multi-section design, the maximum permissible length

of each ladder section is 6 metres.

In addition, the top exit must be equipped with an exit step and a double safety barrier.

2.4 Operating

instructions and

training

The operator is under obligation

• to compile operating instructions for the use of the fixed ladder system. These

instructions must contain all necessary information for safe use of the equipment.

• to instruct personnel using the equipment at least once per year, on the basis of the

operating instructions.

• to inform personnel using the equipment that the emergency-ladder systems may

only be used in the event of fire and for maintenance.

2.5 Personnel 2.5.1 Use

The operator must ensure that fixed ladders are only used by personnel familiar with

the fixed ladder system. Personnel must be in appropriate physical condition to use the

fixed ladder system.

Persons under the influence of drugs, alcohol or medication reducing reaction times

must not be allowed to work on or with the fixed ladder.

2.5.2 Assembly

The fixed ladder must be assembled by specialist personnel.

Specialist personnel are authorised by the operator. Such personnel are persons whose

professional training, specialist know-how and knowledge of the relevant regulations

place them in a position to carry out the tasks assigned to them and identify and avoid

possible risks.

3. Technical description

4. Assembly

4.1 Safety instructions • Ladder systems must always be installed vertically.

• If the wall brackets are mounted with screw anchor systems, use only building-

authority approved screw anchor systems. The company carrying out installation

is responsible for the work and must examine the masonry thoroughly. In the event

of uncertainty, contact an expert for the planning of structural framework or a

specialist consultant from the company which manufactures the screw anchors

(mandatory in accordance with DIN 14094-1). The attachment of the individual wall

bracket must be capable of withstanding a total extraction force of  3 kN and, in

combination with a fall arrester system (e. g. the Zarges ZAST fall arrester system),

an impact force of  6 kN. Screw anchors are not included in the scope of delivery.

• Where it is necessary to cut components to size, this work must be performed by

specialist personnel on-site.

> Deburr all edges.

> Restore anti-corrosion protection.

• Screws and nuts:

> Use screws and nuts from ZARGES or screws and nuts of equivalent quality.

> Secure screwed connections with self-locking nuts.

> To ensure easy and safe assembly, use a suitable high-performance anti-wear

agent designed for heavy-duty use on stainless steel screws in the assembly area.

ZARGES recommends the product Chaast, manufactured by the Hebro company.

> Tighten screws to the following torques:

4.2 Recommendations

for assembly

4.2.1 Preparation

• For a better overview, spread the fixed ladder components out on the ground and

pre-assemble them segment by segment.

4.2.2 Order of assembly

As the setup will vary according to specific on-site conditions, there is no prescribed

order of assembly.

Recommendation:

• Carry out assembly starting at the top and working towards the bottom. Observe the

prescribed dimensions and spacings.

• The top rung must be flush with the edge of the building or machine.

• The topmost wall bracket should ideally be attached in the area of the top two rungs.

If otherwise not possible, at least between the second and third rung.

• Each ladder section must be attached with two wall brackets or four single wall

brackets. The wall brackets must not be more than 2.0 metres apart.

• The topmost back hoop is attached to the stile extension or the guardrail of the

bridging.

• Wall brackets can be pre-assembled on the supporting structure, following the

planned route of the ladder system. It is essential to ensure flush alignment.

• The platform mounting plates can be pre-assembled for each platform. They must

be assembled flush (both horizontally and vertically).

• Following pre-assembly on the floor, ladder systems (even if they comprise several

ladder segments) can be lifted using lifting tackle of suitable load-bearing capacity.

To prevent damage to the ladder connectors and the overall structure during lifting,

stabilise the ladder system, for example using tensioning straps spanning at least 2

to 3 rungs in the area of the ladder connections. If necessary, reinforce, for example

with wood.

• Where necessary, shorten the lower section of the ladder and the ladder safety cage

to suit on-site conditions. Restore anti-corrosion protection.

4.3 Special notes The assembly instructions are in the form of diagrams.

The following must also be observed:

> Safety instructions in Chapter 4.1 Safety instructions.

> The notes below on the individual assembly steps.

Double-sided wall brackets (U-shaped bar), single-sided wall brackets

> Check that the surface of the substructure is flat and perpendicular; use adjustable

wall brackets if necessary.

> Mount each ladder segment with at least two double-sided U-shaped bars or four

single-sided wall brackets.
