Wharf Boarding Ladder

1. Description of Wharf Boarding Ladder

Wharf boarding ladder is an equipment for people boarding and disembarking safely and favourably during oil tanker operating at modern size oil dock. The conventional boarding equipment accomplish the purpose by accommodation ladder of tanker. During the development of oil dock, latter-day size oil dock, special naked pier, dock surface is discontiguous and too high in elevation, the ship bump and drift continually and strongly during operation.

Distance between the shipboard in berth and the edge of dock is too long because of the large fender, in this condition, it is difficult to settle the contact between ship and dock with accommodation ladder. So as to accelerate loading work of tanker and ensure that people is safe during board and disembarking, the boarding ladder almost become a necessary equipment same as marine loading arm at oil dock.

2. Wharf Boarding Ladder Characteristics

(1) The material of ladder body is aluminum alloy, it is light and safe.
(2) Adopt four-link mechanism for steps, and steps will keep in horizontal when the ladder changing in a range of minus 45 degrees to 60 degrees.
(3) The triangle ladder and front ladder are connected with single point, so that the land wheel under triangle will still keep contacting with deck of ship steadily and be immune from influence from bump of ship and inequality.
(4) The hydraulic system is arranged suitably, weather proof and convenient to maintain.
(5) Locking performance of the lifting mechanism is firm and interlocked.
(6) The electric control system is designed independently by our company and adopt domestic and international products of famous manufacturer for main components, has reliable quality and good performance.
(7) The wireless remote made operating more convenient.

Our boarding ladder completely meet following government standard:

(1) Hoister design standards
(2) Steel structure design standards
(3) Chemical and petroleum enterprise design standards—fireproof electrics
(4) Handing oil dock fireproof design standards
(5) Measurement of dry film thickness
(6) Surface rust grade and scale removal grade of steel before painting
(7) Erection quality test criterion for harbor equipment
(8) Hydraulic system general technical specification
(9) Steel and alloy chemical analysis
