High Quality Marine Oil Dock Boarding Ladder
The boarding ladder must have good technical performance for the environment though its function is simple. For adapting to the fluctuation of ship to dock and the happenchance, a detail analysis about information of hydrography, weather and ship which shall arrive of the port will be carried out during design, to confirm the suitable operation condition and choose the correct scheme and reliable preventive measure so as to attain anticipative purpose.
There are many types of boarding ladder for selection. Usually adapting mechanical and hydraulic drive system for drive mechanism of boarding ladder, and equipped various protection device as per requirement during design to ensure each drive mechanism safe operation, determine to adopt explosion proof electrical equipment for boarding ladder according to the characteristic of handing oil at dock.
Selection of boarding ladder shall be carried out according to dock capacity, change of tide, condition of dock surface and cost performance. Customer should fill the following parameter list and submit it to the manufacturer so as to confirm the envelop range, basal dimension and load information of boarding ladder.
