Here are some examples of questions we might ask when providing a quote on LifeLadders®:
- How many ladders do you need? Higher volume = Discounts
- What length of ladders do you need? LifeLadders® come in modules of 30 cm. They should project down 1 meter below lowest water level
- Do you want LightUnits for your LifeLadders®?
- Do you prefer to install ladders with or without handholds?
- When would you need the LifeLadders® delivered?
To better help you, we might ask additional questions:
- What is the construction of your quay? Do you have challenges with ladders being unsupported for the lower part?
- How many and what kind of ladders do you have today?
- Are your current ladders installed in niches or protected by fenders?
- How many ladders do you replace every year?
- What is the estimated lifetime for your current ladders?

Yellow modules of reinforced polyamide (PA6IM GF30) are tied together by static ropes of Dyneema® fibers (Ø5 mm, SK78, Breaking strength >2,0 t) and held apart by rubber spacers (EPDM Shore A85), resulting in a stiff yet slightly flexible construction, perfect for climbing.
No. The ropes of Dyneema® fibres are static and will not stretch. During assembly of a LifeLadder®, knots and splices on the ropes will tighten, creating a bit of excess rope. Please follow the Assembly Guide for optimum assembly.
The lifetime of a LifeLadder® is expected to be +20 years.
The Danish Technological Institute, the plastic manufacturer and the plastic compound supplier have assisted in validating this lifetime expectancy.
Traditional galvanized steel ladders typically have a shelf-life of 12-15 years.
The UV weathering resistance of the color is 6,5 on a 1-8 scale, which is very high for a highly visible bright color. Should the color change over time from exposure to sunlight, it will fade slightly towards white and remain visible against the darker waterfront.
Freeze tests show that ice inside the modules will not cause the plastic to break.
Marine growth is expected to have same impact as on ladders of other materials. LifeLadder®’s visibility will be maintained above water, continuously providing a superior level of safety.
The Modules and Spacers will sink, avoiding damages to ship screws.
Due to their size (4x4x4 cm), the spacers do not pose a risk of being swallowed.
No. The ropes are of Dyneema® SK78, developed for marine and off shore environments and are used worldwide for fishfarms, mooring of large vessels etc.
Dyneema® is a super-strong fiber made from Ultra High Molecular Weight Polyethylene (UHMWPE).
Despite the long lifetime of +20 years, the components of the LifeLadder® will eventually degrade.
The LifeLadder® can be installed on almost any waterfront structure of wood, concrete, stone, sheet pile, etc. It can also be mounted on pontoons and bridges.
Most of our customers prefer to handle the installation of LifeLadders® themselves or leave the installation process to an external maintenance team.
We at Port-Safety do not perform installations, but we will be happy to help you get in contact with a professional installation team.
Assembly and Installation guides are included with the LifeLadders®.
Please contact us if you have any questions before or during installation.
The bracket for mounting is made from 8 mm 316 stainless steel. Bolts are not included, as they depend on the material of the quay wall. The bracket is prepared with extra holes for the bolts to allow flexibility in the mounting.
The surface of the stainless-steel Brackets is very small in comparison to the surface of a steel quay wall; thus, no galvanic corrosion is expected.
The recommended maximum distance of unsupported lower end of LifeLadder® is 1,6 meters. The LifeLadder® should go 1,0 meter below lowest tide, making distance from the lowest bracket to the water surface at lowest tide 0,6 meters.
At night, the LightUnit’s two LEDs illuminate the rungs and side rails of the ladder, providing a clear direction to safety. To download a Technical Data Sheet on the LightUnit, click below.
Yes, we offer two versions: Solar Powered and Grid Powered. The Solar Powered version functions autonomously without connection to the power grid. It can be installed in most locations where it receives sunlight.
The Grid Powered version must be connected to the power grid. It is the best choice in dark/shady locations and in geographies with long winters.
The Solar Powered LightUnit is designed to function all year round up to 60°N, as long as the solar panel is in a fully exposed position with no disturbing shadows from buildings, trees etc. A built-in algorithm optimizes energy consumption by adjusting the light level dynamically.
A partly covered solar panel will result in a reduced ability to charge the battery. If a solar panel is completely prevented from receiving sunlight, the batteries will not be charged. The LightUnit will continue functioning until the energy stored in the battery is used up.
No. The LightUnit is an autonomous system that needs no taken care of. In dirty environments, the solar panel may need occasional cleaning. Expected Battery lifetime is 10 years
Yes. The LightUnit is made of reinforced polyamide and the solar panel is made of hardened glass – designed to withstand the weight of a person.
The solar panel’s smooth glass surface is enclosed by a protruding anti-slip frame of reinforced plastic.
Yes. The LightUnit is waterproof rated IP68. The transparent lid is equipped with an IP68-rated valve that ensures pressure equalization in the electronics compartment.
The LightUnit is CE-marked and is currently undergoing TÜV-certification.
The plastic resin is colored during production. The standard yellow color (RAL 1016) is chosen for its great visibility even in low light conditions. Color customization is an option that we can offer at an additional charge. Please contact us for further information.
The rungs are designed for anti-slip: The profile of the LifeLadder® rung combines the traditional shape of a steel ladder’s tilted square shaped rung profile with a more ergonomic circular shaped profile.
Should a LifeLadder® be impacted by e.g. a vessel, one or more plastic parts might break and should be replaced. The intact plastic parts of the LifeLadder® can be reused.
Yes. The ropes inside the LifeLadders® are made of Dyneema® fibers and are very strong (Breaking strength >2.0 t).
The ladder’s plastic parts will break before the ropes do, and thus will any damages be visible and easy to inspect.
If a LifeLadder® has been damaged, the broken parts should be replaced: You will need a Repair Set. Please contact us with a description of the length of the broken ladder, and we will help you acquire a suitable Repair Set.
2x Modules, 8x Spacers, 2x Clamps, 4x Top-plugs w. ropes of appropriate length.
Please indicate the length of the broken LifeLadder® when ordering a Repair Set.
Rules & Recommendations
Yes. LifeLadder® is designed to comply with European Standard EN 14329. This standard applies for all 34 CEN CENELEC countries including Denmark, Norway, Sweden, Finland, Germany, Netherlands and United Kingdom.
European Standard EN 14329 recommends safety ladders to be installed no more than 30 m apart. EN 14329 also describes the recommended dimensions of a safety ladder, which LifeLadder® of course complies with. The design meets the EN14329 and ILO recommendations for Safety and Health in Ports; among others 40cm length of each rung and minimum 15cm from mid rung to quay wall.
