Design and structure vary according to each type of gangway, but in general they are made from welded steel plate that forms a closed box and are strengthened internally by transverse corbels.
The whole structure is made from independent elements with watertight, sealed sections. These are assembled with thick lintels that are attached with highly resistant, controlled torque screws.
This type of construction allows a better quality finish, reduced assembly time and also facilitates future maintenance.
Movement Mechanism
The movement mechanism comprises a system of driving wheels that are propelled by hydraulic or electric motors that directly power the wheel system.
Variety of wheel models with different materials and steering systems:
- Wheels with a metal centre mechanised with a vulcanised exterior cylinder.
- Solid metal wheels on a monorail or bi-rail.
- Wheels with tyres and a guide rail.
- Guided by the wheel rail or with an additional rail.
Boarding ramps and platforms
Mobile gangways are connected to boats using different elevation and range mechanisms, allowing passengers to move from the maritime terminal to the vessels.
Jointed sections: the incline can be varied (within the maximums established by relevant standards) to overcome the vertical distance between the quayside or maritime terminal and the vessel’s entrance. In some models they can be found running parallel to the quay and bridging gantries.
Telescopic pieces. These allow the range of the gangway to vary, using a hydraulic system that is controlled by the operator. These use sealed bearings to move inside the jointed sections. At the end of the last piece are two reinforced steel claws that grasp the vessel’s coupling device, and also an aluminium panel to avoid any obstacle created by the joint.
Intermediate platforms. These landings connect the different jointed sections and bridges.
Hydraulic elevation and telescopic range mechanisms.
The mechanisms for reaching the vessel’s entrance have an electro-hydraulic action.
A hydraulic system located in a locked cabinet feeds the cylinders of one or more elements that comprise the system in order to achieve the required range with the necessary strength.
