To prevent the damage of boat s going under the ladder in case of alternating water level it has a boat fender in prolongation of the ladder. The ladder has a handrail s on both sides for safety. The construction of an accommodation ladder guarantees, that the Step footing steps are horizontal in each angle of inclination of the ladder.

Unreferenced stub auto yes date December 2009 Image Hook ladder.png thumb 200px right Hook ladder The hook ladder also called a pompier ladder was once a very important tool of the fire department as firefighters could theoretically reach every floor of a building with it. It consists of a simple 2.5 metre ladder with a long, flat hook on its top, with serrations on the underside which gripped the sill. A firefighter denied use of stairs inside a tall structure would lean out a window with the pompier ladder and swing the hook through the window above them, latching the hook to the window stool. They would then climb up the ladder, enter the window above, and repeat the process for as many stories as necessary. The hook ladder was previously used by fire departments all over the world, but its use has been discontinued in several countries as turntable ladder s and fireproof stairwell construction have provided safer and more effective alternatives for ascent. In the former Kent Fire Brigade KFB of the 1960s, raw recruits were trained at the KFB Training Centre, Linton , near Maidstone. The Kent ladders had a fixed eye by the top round rung . After a degree of competence was achieved, the trainee had to climb the ladder to the first floor, enter, straddling the window sill one leg in, one leg out then hoist and twist the ladder into the next floor s window, above. He then climbed back onto the ladder and mounted same hand, same foot, until he reached the next floor. Once there, he attached a hook on a belt around his waist into the eye at the top of the ladder, took one hand and one foot off the ladder, shouting Hooked It was not unknown for an instructor to be waiting on the second floor to give the hook a kick, making it go back several teeth.

Named after noted free solo ist John Bachar , Bachar ladder s typically consist of PVC rungs joined by webbing or cord to create an unstable structure similar to the ratlines of a sailing ship. However, unlike ascending ratlines leaning inward using one s legs for upward progress and arms for steadying, the Bachar Ladder is typically hung at an overhanging angle of 20 degrees and climbed with arms alone. While similar in inclination and intent to a campus board , the Bachar ladder swings slightly even when tethered, requiring the climber to use more core tension to maintain stability.

An eel ladder is type of fish ladder designed to help eel s swim past barriers, such as dam s and weir s or even natural barriers, to reach upriver feeding grounds. Many eels are fish migration catadromous , living in fresh water but Spawn biology spawning at sea. The basic design of an eel ladder has the eel swim over the barrier using an eel ascending ramp, which provides the eels a climbing substrate to push against while slithering upstream. For some higher barriers, elevator style systems are also used. An eel ladder typically consists of four parts an eel ascending ramp , a supporting structure , a water feeding system , and a side gutter . The side gutter provides an attraction flow to draw eels toward the ladder, the water feeding system ensures the proper flow of water to the gutter and the ramp, and the supporting structure mounts the ladder to the barrier. The eel ascending ramp can be a fairly simple constructions, such as a hollowed out tree filled with recycling recycled fishing net , or a more complex structure designed to accommodate specific species or ages of eels.

The design and construction of the ladders is tightly specified ref http www.opsi.gov.uk si si1987 Uksi 19871961 en 1.htm The Merchant Shipping Pilot Ladders and Hoists Regulations 1987 ref by international regulation under the International Convention for the Safety of Life at Sea SOLAS regime. Construction The ladders are made by threading and fixing a series of hardwood , machined steps, each approximately 500mm x 110mm, onto two pairs of 28 30mm diameter manila hemp manila ropes , and binding each step to the ropes at 350mm intervals. At a maximum interval of 8 steps, the standard step is replaced by a spreader , which is an elongated version of the standard machined step, with a minimum length of 1.8 m. The spreader s function is to prevent the ladder from twisting in the prevailing weather conditions when in use. The lowest four steps of the ladder are normally made from a synthetic or composite resin , which is more resistant than hardwood, to the interaction between the host vessel and the pilot boat coming alongside. Because the decks of most commercial ships are far above the waterline, pilots and others who need to come aboard at sea can usually only do so if a pilot ladder is put out. When not being used, the ladder is stowed away usually rolled up rather than left hanging.
