Summary of FRP Ladders Document

Uses and Characteristics
FRP ladders are made from fiberglass and isophtalic resin profiles, offering benefits such as resistance to chemicals and weather, durability, lightness, dimensional stability, dielectric properties, no maintenance, and easy installation.

Reference Norms
The ladders adhere to standards like UNI EN ISO 14122-1:2016 and UNI EN ISO 14122-4:2016 for machinery access safety, and UNI EN 131-2 for portable ladder features and testing.

Applications
These ladders are ideal for corrosive environments and are used in industries such as chemical, galvanic, mineral, textile, food, electric, oil, tannery, water treatment, marine, and paper.

Materials
The document describes ladder components like stiles, rungs, anchor brackets, safety cage profiles, and fixing devices, detailing dimensions, weight, and color.

Dimensions of the Ladders
Specifications include ladder heights, maximum heights for single and staggered flights, and dimensions for ladders with and without safety cages.

Types of Ladders
Describes standard vertical ladders and those with front or lateral exits, detailing specifications for stiles, rungs, and safety cage components.

Ladder Fittings
Includes information on safety fittings, gates, closing devices, and recommendations for ladder extensions and fixing methods.

Assembling Instructions
Provides instructions for ladder extension, fixing to concrete or FRP gangways, and assembling safety cages to ensure proper installation and safety compliance.

Specifications
Outlines ladder specifications, including dimensions, materials, and safety features. All ladders are grey RAL 7035 with a usable rung width of 400 mm. Safety cages have specific height calculations and maximum distances between hoops and anchor points.

Standard Ladder Types

Type 1: Suitable for heights up to 10,000 mm, requires division and junction devices for heights above 7,000 mm.
Type 2: Used for heights up to 3,000 mm, with a maximum anchor point distance of 1,200 mm.
Type 3: Designed for manhole access, usable with potable water, and requires division for heights above 7,000 mm.
Type 3 Plus: Reinforced for stability in high wind exposure, suitable for heights up to 10,000 mm.

Ladders with Exits
Includes front and lateral exit options for Types 1 and 3, with specific recommendations for safety steps and gates. Exit dimensions and additional safety features are detailed.

Rest Platforms
Required for ladders over 10 m, with specifications for structure and safety features. Maximum height per flight is 6,000 mm.

Accessories
Includes safety accessories like wall bars, safety steps, gates, and closing devices, all in grey RAL 7035.

Assembling Instructions
Details on ladder extension and fixing, including the use of junction devices for ladders over 6 m and maximum spacing for anchor brackets based on ladder type.

Fixing to Concrete
Requires stainless steel or fiber-reinforced plastic anchor brackets, using S.S. screws with a minimum diameter of M8 mm and anchoring dowels at least 60 mm long.

Fixing to FRP Walkway
Involves using S.S. or FRP anchor brackets with S.S. AISI 316 screws and self-blocking nuts.

Assembling the Safety Cage
Necessary for ladders over 3 meters high, provided pre-assembled for easy assembly. Drilled holes must match screw diameters to prevent backlash.
