USA Sliding Door, Inc: Actuation equipment for clas II and III sliding watertight doors

Types of Actuation Equipment for Class II and Class III Sliding Watertight Doors

Every vessel and each installation is individually considered as to space constraints. We will assist you in your selection of the actuating equipment that best suits your installation.

MODULAR REMOTE HAND PUMP STATION

CLASS II DOOR SYSTEMS:

Class II Door Systems are Hand Hydraulic operated Doors. You will have a Hydraulic Hand pump & Directional Control Valve on each side of the bulkhead to Open & Close the Door. For emergency situations a Modular Remote Hand Pump Station mounted above the bulkhead deck enables you to Close the door only.

A light indicating station will be mounted to the Modular Remote Hand Pump Station indicating if the door is open or closed. A Central Indicating Station mounted on the Bridge indicates the door positions for all like doors on your vessel.

Each Actuating System has three separate Parts.
1. The Local Control Equipment at the door.
2. The Modular Remote Hand Pump Station (IF REQUIRED).
3. The Central Indicating Station (IF REQUIRED).

Usually item No. 1, the Local Control Equipment is your concern regarding space constraints. We have found that most customers prefer this system to be our Modular style.

The Modular System has all of the Local Actuating Equipment Mounted to a bulkhead plate. The equipment includes all of the electrical and hydraulics required by the Regulatory Agencies for its Class. Each component is mounted to the modular plate, pre-piped, pre-wired and tested prior to shipping from our works. This system reduces installation time by 65%. if your space constraints do not allow for the Modular Plate next to the door you can order a non-bulkhead penetrating Modular Plate System.

The Modular Plate has the majority of equipment mounted to it but can be mounted to a 90 degree bulkhead from the door or elsewhere within sight of the door.

The Hand Pump and Manual Control Valve for the opposite side of the bulkhead will have to be mounted individually and piped through the bulkhead to the Modular Control Plate. If space constraints eliminate this choice all of the Local Control Equipment can be ordered separately and dispersed around the door where space allows. This dispersed equipment is then mounted, piped, and wired at the shipyard installation.

CLASS III DOOR SYSTEMS:

The Class III Door Systems are Electro and Hand Hydraulically operated. There is an Electric Control Switch, Emergency Hand Pump & Directional Control Valve on each side of the bulkhead to Open and Close the Door. For Emergency situations a Modular Remote Hand Pump Station mounted above the bulkhead deck enables you to Close the door only. Affixed to this station is a Light Indication Station, which indicates if the door is open or closed.

A Central Control & Indicating Station is mounted on the Bridge. This station has light indication showing the door position status. It also has a Master Switch that Closes all of the doors simultaneously.

Each Actuating System has three parts.
1. The Local Control Equipment at the door.
2. The Modular Remote Hand Pump Station (IF REQUIRED).
3. The Bridge Control & Indicating Station.
