WHY BLUE SKY?

1. Blue Sky used to be the first factory special for dispenser controller in China. With over 20 years' history in this field and continuous optimization & innovation, Blue Sky makes controllers with as many functions as you like.

2. Almost every part is made by Blue Sky itself, including controller, flowmeter and pump, since Blue Sky finds that other factories' products cannot meet its demands and requirements due to the increasingly thriving business all over the world.

3. Professional, steady and advanced as Blue Sky is, its products already passed ATEX, OIML and other standards.

4. With top-ranking staff, some of which are from the first dispenser factory in China, and some belong to the new generation, Blue Sky dispensers boast sound market reputation, extensive business channels, solid customer foundation and strong market competitiveness.

5. Persisting to the principle of "making trade services the forerunner of the business", Blue Sky will strive for high efficiency, passion, integrity to provide customers with superior trade services.

The dredge Drag Head is a steel structure that is connected to the Dredger by a Suction Pipe. Supported by the gantries and by using hydraulic winches the dredge drag head and suction pipe are let down onto the sea bottom in order to suck a mixture of water and sand.
In order to dredge in waves, the suction pipe is suspended from special davits, which operate with heave compensation to ensure that the drag head nozzles stay in contact with the sea bed. The control of mixture of water and sand is done by a so-called dredge drag head visor. The visor controls the amount of water that enters along with the sand. In some cases this visor is hydraulically controlled.

To cut the sea bed, the dredge drag head is equipped with replaceable teeth and water jet nozzles. The nozzles are placed at the front of the dredge drag head and used to cut the sand at the sea bed vertically, while the replaceable teeth are placed at the back to cut horizontally.

The drag heads contributes to lower fuel consumption by having a low drag resistance, high production by mixing highest possible ratio of slurry, sand, clay and rocks with water efficiently.

Universal Dragheads
Our universal dragheads offer a combination of high excavation capabilities for loosening the soil and optimized hydraulic properties for mixture transportation. High mixture concentrations are possible in many different kinds of soil. Concentrations are more stable even in more compact soils, where the water flap is blocked in an optimized position. Production can be optimized by controlling the contact force of the draghead to the ground through a swell compensator system.
The soil to be dredged is loosened by cutting teeth at the visor and the effect of pressure water supply through special nozzles. The visor is equipped with an adjustable water flap for the supply of additional transport water when dredging in soft grounds.

US Dragheads
Our US dragheads are particularly suitable for dredging firmly-packed and strongly-binding types of soil. Due to their modular design, the US draghead can easily be converted into a the draghead with a turbulence visor or a universal visor. The US visor is equipped with knives and ripping teeth to loosen compact soils. Pressure water is used for fluidization of the ground. The US visor has adjustable water inlets on top, allowing the supply of additional transport water in soft grounds. Wide dragheads are equipped with two independent visors, so that the whole suction area is in close contact to the ground even on uneven ground.

Active Dragheads
Our active dragheads offer the highest production rates possible, even in compact soils and at varying dredging depths. The pressure nozzles can be arranged at the visor carrier and/or at the visor itself according to customers' preferences. The hydraulic power pack can be installed on deck or as integrated part of the draghead. Various control systems are available, enabling efficient use of the active draghead. The basic version of the control system includes continuous position indicators and switches for bridge desk mounting. Advanced dredge control and automation systems automatically adjust the visor position and water flap. Visor position can be controlled, for instance, with constant position, pre-selected Grab depth or cylinder force and water flap position to suction pressure at the draghead.
