The latest Quick stabilizer is 35% more powerful but has substantially the same bulk as the X56
by Niccolò Volpati
Quick Gyro X75 is the latest and biggest stabilizer in the range since the acquisition of MareCalmo, a start-up proposing vertical axis stabilizers. Since then, the engineering team at Quick has been working to improve the product, widen the range and launch it on an international scale.
Compared to other gyro stabilizers, the new models have a horizontal axis, a feature that becomes even more important when the weight increases, as in the case of the X75. When operating, a metal “ball” with a vertical axis especially strains the lower bearing. The horizontal axis, on the other hand, has a better weight distribution, and the strain is distributed on several bearings.
This is also the reason why the metallic mass of a horizontal-axis stabilizer can turn less quickly while maintaining high stabilisation efficiency. So, the other big advantage is that they reach their operating rotation earlier than vertical models. This is an important aspect because from the moment it is switched on to its actual operation as much as thirty minutes can go by. Moreover, a stabilizer, which rotates less quickly also has lower power consumption.
THE X75 IS THE FIRST LIQUID-COOLED STABILISER TO ENSURE THAT THE BEARINGS LAST LONGER, REDUCING MAINTENANCE
TO A MINIMUM.
The horizontal axis is ideal for heavy stabilisers because the stress is distributed not only on the lower bearing.
The X75 has features that differentiate it from all other models in the Quick range. The first distinctive feature is that the bulk does not change. The power is higher, revolutions are higher, but the size does not differ.
Yards are always looking for powerful, efficient stabilizers, but without increasing volumes, because there is not an infinite amount of space in the engine room. It still has a horizontal axis, and it can supply power of 75,000 Nm, almost twice as much as the X40 model, which has the same bulk as the X75. And there is one more thing that differs from all other Quick stabilizers. The X75 has a liquid cooling system. It does not have a vacuum mass, but it does have a cooling system.
THE X75 IS THE MOST POWERFUL STABILISER
IN THE QUICK RANGE.
WITH THE SAME BULK
AS THE SMALLER MODEL, IT OFFERS MORE POWER.
In this case, the engineering team considered that to further reduce maintenance it was necessary to cool the abutments and bearings and not rely on the air-cooling system only. In a compact stabiliser, which nonetheless reaches a thrust of 75,000 Nm, cooling is an essential precaution if you want a product that will last in time without too many maintenance issues.
From the X2 to the X75 any boat from 7 to 24 metres in length can count on the ideal model for its specific characteristics.
The X75 is therefore ideal for boats of up to 400 tonnes, i.e., from 75 to 90 feet, and the bulk is very small as it is a one-meter cube. The exact measurements are 95x95x103 cm. Compared to the X56, there is a 35% increase in rectifying power with only a 5% bulk increase.
