Companionway Ladders for Ultimate Security

Companionway ladders, also commonly referred to as ship ladders, provide fixed secure access to heights under 3m. Companionway ladders are known to be safer to use than a vertical ladder thanks to their slope inclined design. The design provides more stability, while still maintaining the flexibility to suit most internal and external locations. Ship ladders or companionway ladders are often a preferred choice when a ladder is frequently used within a work environment.

Companionway ladders are angled between 60 to 75 degrees and the ladders are often used when space is minimum and insufficient for a staircase. The ladders can be integrated into guardrail edge protection to form part of a planned comprehensive access strategy. We equip these systems with a single line of a handrail on each side, to provide extra safe hold. Our companionway ladders or ship ladders are lightweight and are available for freestanding or as a permanent fixture. This ladder system provides simple access to roof areas or raised floors such as mezzanines.

All you need to know about this solution...

The Work at Height regulations 2005 (WAHR 2005) require that whenever a roof or raised area that has to be accessed, this access must be undertaken in a safe and planned manner.

Whatever your access needs or problems, a vertical ladder can be designed to give you safe and secure access to any raised areas while complying with all Work at Height Directives.

Where design parameters permit, companionway ladders are more practical to use than vertical ladders. Companionway ladders comply with the following standards:

BS 5395: Part3. 1985
