Quick Release Mooring Hook
Installed at dock, Quick release hooks are special equipments for winding and tying of ships. They are the update products of mooring dolphins. Compared with cleat, they reduce working intensity, increase working efficiency and improve safety and reliability.
Quick release hook consists of integrated
electrical winch and release systems. They are suitable for large tonnage ships mooring harbors that require fewer workers and quick releasing and winding of the hawser under heavy storm or other dangerous status.
Eminent is a professional manufactory for design, production, installation and service of Quick Release Hook(QRH). We learned about different design philosophies from various manufacturers , drawed on the pick of the basket and we have put
the client's valuable comments into the basket together with our own experience. Eminent Quick Release Hook as an excellent product came out to the world. Especially, our designers with a solid experience continue to update in new material and new technical process in evey year. We have own 38pc patents only for Quick Release Hooks.
We can supply you various type QRH(single, double, triple or quadruple hooks as required by the layout of the terminal, although other configurations, e.g. back-to-back,)with local manual hook release, electric, hydraulic and pneumatic remote release systems for the hooks, with the activation devices completely integrated into the hook assembly. And also can supply you the all type QRH installed mooring load monitoring system. We named it "Eminent Tysun Intelligent Hook".
We can produce custom-made quick release hooks base on your requirement.
Each hook is proof tested to 150% of its rated load, and the release mechanism is tested at full load rating at our own test facility and is witnessed by a surveyor from an independent Classification Society( LR,DNV,BV,ABS
etc.). If remote release is incorporated the hooks can be released from a remote location (generally the control room or jetty office) as well as by activating a button on the control panel mounted on the side of the hook. Local displays of the mooring load tensions and audible and visual alarms can also be incorporated into the hook.

3 Capstan Assembly
In order to save time and to ensure maximum safety,Each mooring unit is equipped with an integrated electric capstan motor assembly, the mooring ropes are lifted up to the mooring hooks by using the integrated electrical capstan. The capstan which is reversible is operated from a foot switch.
Capstans are integrally mounted to the hook units and are certified for Ex area where applicable.
This capstan complies with following specifications:
Starting pull: 40KN = max line pull Running pull: 15KN-30KN = normal line pull Line speed: 20 m/min-25m/min
Back-stop: 1.5 times normal line pull
The capstan gear box is a self locking device to prevent the capstan head from turning in the opposite direction due to the weight of the mooring line at power off.
The mounting model for motor is suggested: Horizontal.

SPECIFICATION AND PERFORMANCE DATA
Each hook will be tested as follows: Test load =1.5 times the SWL
Release load = 1.0SWL Manual release force for release bar < 170N@SWL
The movement range of hooks:
Vertical: -15°(MLMS model), -5°,0 to 45°, 55°.
Single hook unit: 90°/90°
Double hook unit: 90°/45° (left hook)

45°/ -45°(Middle hook)
-45°/-90° (right hook)
Quadruple hook unit: Same as Triple hook unit.
MOUNTING BASE METHODS
Bolted to steel deck
Welded onto steel deck
Different arrangements available
Hooks can be installed on both sides of post Hook post delivered with or without capstans Free standing capstans
5. INTELLIGENT HOOK
Eminent Intelligent hook includes Remote Release System, Status Sensors and Mooring Load Moritoring System. It is possible to performe Quick Release hooks release, monitoring out of the dock in emergency. Ensure the Security of Jettyand operators.
Remote Release System and Status Sensors
To operate the release system from the remote location a central remote control
panel is included in the delivery. The panel includes:
Hook release indicator
Hook release push button
A master release push button
An emergency release push button
A power on/off indicator lamp
A power on/off switch
Display of hook loads
Hook status (locked/unlocked)
The remote quick release panel RQRP is
connected via the LAN/Ethernet cabling to
the hook stations. Functionality of the hooks is controlled from the network dedicated processor LAN Micro Sensor (LMS) built into
the RQRP. Control of the hook’s
open/close functions is separated from the central computer system due to safety reasons. Furthermore a special coded message protocol between the RQRP and the hook station LAN/Ethernet unit is made to avoid accidental release of the hooks.
The design of the RQRP allows to have multiple RQRP’s connected both for
hazardous and safe area.
Mooring Load Monitoring System.
(1) The Load Pin:
The load pin is manufactured as a direct replacement for the hook swivel shafts.
The load pin shall have the same safe working load as the corresponding mooring
The load pins are made of stainless steel
17-4PH, which is a special quality of stainless steel with an extreme high strength.
(2)The Amplifier and Control Uint
A dedicated amplifier module LM4 that is integreted into the control panel for capstan has been designed to protect the load cells from
the cable network to aviod damage in case of
induction caused by lightening. The amplifier module is equipped with a proceesor unit that will track of the loads. This means that the load values are
memorized in this amplifier module keeping track of about 1year of data. Should the central computer
for some reason fail, the history is always available in the amplifier unit.Temperature ranging from -40℃ to 85℃
(3)Load Monitoring on Central Computor
The load information is in real-time sent to the central computor for visualization.
This central computor acts as server for the data recorders located in the hook remote release control
The central computor system will also host the
Vessel Docking Aid System Software. Display
screens will be available to the operator thought a standard MS windows interface and will form an
