Product Description

 

Product Description

The Quaydots Tandem Headblock gives significant improvements in productivity. It is specially designed to be operated on a ship to-shore crane and quickly shift between a Quaydots Spreader and a regular ship-to-shore single lift or twinlift spreader. The Tandem Headblock is equipped with heavy duty twistlocks, and can also be equipped with an optional automatic connector for power and signals to the spreader. The sheave wheels automatically expand to a wide position for tandem lift when connecting to a tandem spreader and to a narrow position when attaching to a single or twinlift spreader.

The headblock consists of a center platform and two identical end beams. The end beams are designed as two vertical plates with the two movable sheave wheel arm assemblies, the locking shaft mechanism and the heavy duty twistlocks placed between them. The hydraulic powerpack, the electrical cabinet and a cable damper (optional) are mounted on the center platform. If the headblock is equipped with the optional Quaydots nector upper part, it will also be mounted on the platform. Made of high quality steel, the Quaydots Tandem Headblock pro vides high lifting capacity with a low nominal tare weight thanks to the end beam design. The Headblock is designed in accordance with EN13001. All components can be easily assembled, adjusted, removed and are accessible for inspection and maintenance. The headblock comes with a controller, reducing and preventing downtime through improvements in the area of electrical connections.

 

Major Features
· Automatically expand or retract the sheave wheels when moving from single spreader to tandem operation
· Fast trouble shooting
· With the optional autoconnector, quickly shift between a Tandem spreader and a regular ship-to-shore single lift or twinlift 
   spreader, and attach and connect to a spreader without any manual work.
· Fulfils the design criteria among EN13001, DIN 15018 H2B4, FEM 1.001 and British Standard BS 2573


End beam

Two vertical plates in combination with spacer shafts and

gable plates form the end beam box which carries the heavy

load between the headblock twistlocks and the sheave

wheels.

 

Two cylinders drive the sheave wheel arm assemblies in

each end beam to synchronously rotate 60 degrees from the

tandem lift position into the single spreader lift position.

The sheave wheel arm assemblies are fixed in both posi

tions by hydraulically manouvered locking shafts

Headblock Twistlocks

Four heavy duty twistlocks are located in the lower corners of the headblock end beams to engage and lift the spreader. A hydraulic cylinder rotates the twistlock and two sensors indicate the position, Locked or Unlocked. A landing pin safety system is provided to assure that the headblock is properly landed on the spreader before rotating the twistlocks.

A spring loaded landing pin near each twistlock is pushed up into the twistlock housing when the headblock is landed on the spreader.When the headblock is properly landed, the landing pin will activate a sensor. The twistlocks can only be turned when all the corners of the headblock are landed. At the same time, the blocking key is moved high enough so the blocking stop on the twistlock lever arm passes underneath it. If the spreader is not properly landed, the sensor will not be activated and the blocking key will get in the way of the blocking stop. This will stop the twistlocks from turrning.

LED type signal lights are provided to indicate landed (yel low) / locked (red) / unlocked (green)/ Twin mode (blue). These lamps are positioned on the headblock center plat form.

Each lamp panel indicates the status of the nearest spreader end beam. In Tandem mode all four panels are activated. In single spreader mode only lanside panels are used
